Goat Ration Formulation: Balancing Nutrients for Milk Production

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

Lactating goats require 3-4% of their body weight in dry matter daily, with high producers needing up to 5%, necessitating a ration density of 0.65-0.75 Mcal NEL/lb dry matter to meet energy demands, as energy is the primary limiting factor for milk production.
Protein requirements for lactating does range from 14-18% of dry matter, escalating with milk yield and protein content, and are crucial for milk protein synthesis, with lysine and methionine being key limiting amino acids.
Forage, such as quality hay or pasture, forms the nutritional foundation, providing essential fiber for rumen health and a base of protein and energy, while concentrates are used to bridge the gap between forage supply and the doe's specific requirements.
Precise balancing of calcium and phosphorus is critical, with a target ratio of 1.5-2 parts calcium to 1 part phosphorus, to prevent metabolic bone disease and support milk production, alongside adequate provision of water, which is often overlooked but essential for intake and milk volume.
Body condition scoring every 2-4 weeks is the most effective practical method to assess ration adequacy, with a target of 2.5-3.5 for lactating does, and any sudden drops in appetite, milk yield, or rumen activity warrant immediate veterinary assessment before ration adjustments.

Feeding a milking goat is not the same as feeding a dry doe or a growing buck. The lactation cycle places heavy demands on the body, and the ration you provide directly determines milk volume, butterfat content, body condition, and the health of the doe and her kids. This guide walks through the complete process of goat ration formulation, from understanding the science of nutrient requirements to building a practical feeding program with the feedstuffs available on your farm. It is written for dairy goat producers, small farm owners, and anyone transitioning from keeping goats as pets to managing them for milk production. You will learn how to calculate protein and energy needs, balance forages and concentrates, adjust rations through the lactation cycle, troubleshoot common feeding problems, and keep the records that make consistent feeding possible.

At a Glance

A lactating dairy goat needs roughly 3 to 4 percent of her body weight in dry matter each day, with high producers at the upper end.
Protein requirements for early lactation range from 14 to 18 percent of the total ration dry matter, depending on milk yield and milk protein content.
Energy is the most common limiting factor in milk production. Does in early lactation often need a higher energy density than they can consume from forage alone.
Forage should form the foundation of every ration. Quality hay or pasture supplies fiber, rumen health, and a base of protein and energy.
Concentrates fill the gap between what forage provides and what the doe needs. They do not replace forage.
Calcium and phosphorus must be balanced carefully. The ratio should stay near 1.5 to 2 parts calcium to 1 part phosphorus.
Water is a nutrient. A milking doe drinks 1 to 2 gallons per day or more, and intake drops sharply when water is dirty, frozen, or hard to reach.
Body condition scoring every 2 to 4 weeks is the single best practical check on whether your ration is working.
Any sudden drop in appetite, milk yield, or rumen activity warrants a health check before you adjust the ration.

Understanding the Nutrient Demands of Lactation

Milk production is biologically expensive. A doe producing 6 pounds of milk per day is moving a substantial amount of protein, fat, sugar, minerals, and water out of her body and into the milk pail. If the ration does not supply those nutrients, the doe will pull them from her own tissues. The result is weight loss, poor milk production, and eventually metabolic disease. To formulate a ration correctly, you need to understand what the doe is being asked to do and what nutrients are required to do it.

The Lactation Curve

A dairy goat's lactation follows a predictable curve. She freshens, milk production rises sharply in the first 2 to 4 weeks, peaks somewhere between 4 and 8 weeks, and then gradually declines. The shape of that curve varies by breed, age, nutrition, and management. Alpine, Saanen, Nubian, LaMancha, and Oberhasli does all have slightly different production patterns and milk compositions. A Nubian produces milk with higher butterfat but lower volume. An Alpine produces more volume with lower butterfat. Your ration must be adjusted to the individual doe, not to a breed average.

The most important point on the curve is the peak. The height of the peak largely determines total lactation yield. A doe that is underfed in early lactation will peak lower and produce less milk across the entire lactation, even if you correct the ration later. This is why the first 6 to 8 weeks after freshening are so critical. The doe is trying to increase milk output at the same time she is recovering from kidding and often eating less than she needs. She will draw on body reserves to support the demand. Some weight loss in early lactation is normal and acceptable, but excessive loss leads to ketosis and poor fertility.

Dry Matter Intake

The first step in any ration formulation is knowing how much the doe can eat. Dry matter intake is the total weight of feed minus its moisture content. A lactating goat typically consumes 3 to 4 percent of her body weight in dry matter per day. A 150 pound doe producing 6 pounds of milk will eat roughly 4.5 to 6 pounds of dry matter daily. High producers may reach 5 percent of body weight, but this requires excellent feed quality and careful management.

Dry matter intake is not fixed. It rises through early lactation, peaks a few weeks after milk production peaks, and then declines as production falls. In the first week after kidding, intake may be only 2 to 2.5 percent of body weight. This lag between peak production and peak intake is why early lactation is the most nutritionally challenging period. The doe needs more nutrients than she can physically consume, so she mobilizes body fat to make up the difference.

Forage quality has a huge effect on dry matter intake. Poor quality hay is fibrous, slow to digest, and fills the rumen without supplying many nutrients. A doe cannot eat enough of it to meet her energy needs. High quality forage digests faster, passes through the rumen more quickly, and allows the doe to eat more total dry matter. This is why forage quality is the foundation of the entire ration.

Protein Requirements

Protein is required for milk protein synthesis, tissue maintenance, and the growth of the fetus in late pregnancy. The protein requirement is expressed as a percentage of the ration dry matter or as grams per day. A lactating doe needs more protein than a dry doe, and the requirement rises with milk production and milk protein percentage.

For a 150 pound doe, the crude protein requirement is roughly:

Maintenance only: 8 to 10 percent of ration dry matter
Producing 4 pounds of milk: 12 to 14 percent
Producing 6 pounds of milk: 14 to 16 percent
Producing 8 pounds of milk: 16 to 18 percent

These are crude protein percentages. The actual need is for metabolizable protein, which accounts for how much protein actually reaches the small intestine for absorption. Rumen microbes break down some dietary protein into ammonia, and some dietary protein escapes the rumen undegraded. High quality forages and properly processed oilseed meals provide a good balance of degradable and undegradable protein. Soybean meal, canola meal, and fish meal are common sources of bypass protein for high producers.

The first limiting amino acid for milk production in goats is typically lysine, followed by methionine. Most practical rations based on good forage and a balanced concentrate will supply adequate amounts of these amino acids. If you are seeing poor milk protein percentages despite adequate crude protein, consider whether the amino acid profile is balanced.

Energy Requirements

Energy is the nutrient that most often limits milk production. The energy content of feed is measured in megacalories of net energy for lactation, or Mcal of NEL. The requirement is expressed as Mcal per day or as a density of Mcal per pound of dry matter.

A 150 pound doe at maintenance needs about 2.5 Mcal of NEL per day. Producing milk adds roughly 0.3 Mcal per pound of milk. A doe producing 6 pounds of milk needs about 4.3 Mcal per day. Producing 8 pounds requires about 4.9 Mcal.

The energy density of the ration matters as much as the total. A doe has a limited daily dry matter intake, so the ration must pack enough energy into each pound of feed. The target energy density for a lactating doe is 0.65 to 0.75 Mcal per pound of dry matter. High producers in early lactation may need 0.75 or higher. This is achieved by including grains and byproducts in the concentrate mix, because grains are more energy dense than forages.

Good quality grass hay provides about 0.55 to 0.60 Mcal per pound. Corn grain provides about 0.90 Mcal per pound. By blending forage and concentrate, you can achieve the energy density the doe needs. The challenge is doing this without pushing starch too high, which can cause rumen acidosis.

Minerals and Vitamins

Minerals play structural and metabolic roles, and lactation increases the demand for several of them. Calcium is the most critical. A doe producing 6 pounds of milk secretes about 6 to 8 grams of calcium in the milk every day. If her diet does not supply this, she will draw calcium from her bones. This is normal to a degree, but a prolonged deficiency leads to weak bones, poor milk production, and an increased risk of milk fever.

The calcium requirement for a lactating doe is roughly 0.4 to 0.6 percent of the ration dry matter. Phosphorus is required at about 0.3 to 0.4 percent. The calcium to phosphorus ratio should stay near 1.5 to 2 to 1. Excess phosphorus relative to calcium can interfere with calcium absorption and contribute to urinary calculi in bucks, though this is less of an issue in does.

Salt should be provided free choice or included in the ration at 0.5 percent. Trace minerals including copper, zinc, manganese, selenium, and iodine are required in small amounts but are essential. Many areas have soils deficient in selenium, and goats in those areas need supplementation. Work with your extension agent to learn about local mineral deficiencies.

Fat soluble vitamins A, D, and E are important. Goats on good pasture get adequate vitamin A from green forage. Vitamin D is synthesized in the skin with sunlight exposure, but goats housed indoors may need supplementation. Vitamin E works with selenium to support immune function. Most commercial goat mineral mixes contain these vitamins, but check the label to be sure.

Water

Water is the most essential nutrient and the one most often neglected. A lactating doe needs 1 to 2 gallons of water per day, and more in hot weather. Milk is about 87 percent water, so any reduction in water intake directly reduces milk production. A doe that cannot get clean, fresh water will not eat well, and her rumen function will suffer.

Check water sources daily. Buckets and troughs should be cleaned regularly, and water should be cool in summer and ice free in winter. Does drink more immediately after milking, so fresh water should be available at that time. Consider adding a second water source in the milking parlor or in the pasture to encourage intake.

Step by Step Guide to Formulating a Goat Ration

Ration formulation is a systematic process. You are not guessing or copying a neighbor's recipe. You are calculating what the doe needs, measuring what your feedstuffs provide, and building a ration that closes the gap. The following steps work whether you are feeding one doe or a herd of fifty.

Step 1: Assess the Doe

Start with the individual animal. Record her body weight, body condition score, stage of lactation, and daily milk production. For a herd, group does by production level and stage of lactation rather than by breed or age. A first freshener producing 4 pounds of milk has different needs than a mature doe producing 8 pounds.

Body condition scoring is a hands on assessment of fat cover over the ribs, spine, and sternum. Use a 1 to 5 scale where 1 is emaciated and 5 is obese. The ideal score for a lactating doe is 2.5 to 3.5. A doe at freshening should be at 3 to 3.5, and she can be allowed to drop to 2.5 in early lactation. If she drops below 2.5, she is losing too much condition and the ration needs more energy.

Estimate milk production by weighing milk at each milking for several days. If you milk once a day, multiply by 2 for a rough daily estimate, but know that once a day milking reduces total yield. If you do not have a scale, use a calibrated dipstick in a milking bucket or measure by volume in a quart jar.

Step 2: Determine Nutrient Requirements

Use the doe's weight, condition, and production to calculate her requirements. You can use a published table from a university extension service, a nutrition software program, or the calculations below. The National Research Council publishes Nutrient Requirements of Goats, which is the standard reference, but even a simple spreadsheet will get you close.

For a 150 pound doe, use these baseline figures:

Dry matter intake: 4.5 to 6 pounds per day
Crude protein: 0.55 pounds per day for maintenance, plus 0.08 pounds per pound of milk
Net energy: 2.5 Mcal per day for maintenance, plus 0.3 Mcal per pound of milk
Calcium: 0.02 pounds per day for maintenance, plus 0.001 pounds per pound of milk
Phosphorus: 0.014 pounds per day for maintenance, plus 0.0007 pounds per pound of milk

For a doe producing 6 pounds of milk, this gives:

Dry matter intake: 5 pounds
Crude protein: 0.55 plus 0.48 equals 1.03 pounds per day, or about 16 percent of dry matter
Net energy: 2.5 plus 1.8 equals 4.3 Mcal per day, or about 0.86 Mcal per pound of dry matter
Calcium: 0.02 plus 0.006 equals 0.026 pounds per day
Phosphorus: 0.014 plus 0.004 equals 0.018 pounds per day

These are estimates. Actual requirements vary with breed, environmental temperature, activity level, and individual metabolism. Use them as a starting point and adjust based on the doe's response.

Step 3: Test Your Forage

You cannot balance a ration if you do not know what is in your feed. Forage testing is the most important investment you can make in your feeding program. A basic forage analysis costs a small amount relative to the cost of wasted feed or lost production. Send a representative sample of your hay or pasture to a forage testing laboratory. The report will give you dry matter, crude protein, energy, fiber fractions, and mineral content.

Collect the sample properly. Use a hay probe to sample 15 to 20 bales from different parts of the stack. Mix the cores in a clean bucket and send about a pound of the composite sample to the lab. For pasture, clip samples from several areas the goats are grazing. The sample is only as good as the collection method, so take the time to do it right.

If you cannot test your forage, use book values from a feed composition table. These are averages and may not match your specific feed, but they are better than guessing. The variation between different cuttings of hay is large. A first cutting grass hay may have 10 percent protein while a second cutting legume hay may have 18 percent. Feeding them the same way will produce very different results.

Step 4: Choose Your Feedstuffs

The feedstuffs available to you depend on your region, season, and budget. The goal is to build a ration from the most economical ingredients that meet the doe's needs. Forage is the base. Concentrates fill the gaps.

Forage options include:

Grass hay: timothy, orchard grass, brome, fescue. Moderate protein and energy, good fiber.
Legume hay: alfalfa, clover. Higher protein and calcium, excellent for lactating does.
Mixed hay: a blend of grasses and legumes. Often the best choice for balance.
Pasture: high quality pasture can supply most or all of the diet in the growing season.
Silage or haylage: common in some regions, but spoilage risk is higher with goats.

Concentrate options include:

Corn: high energy, low protein. The standard energy source.
Barley: similar to corn, slightly lower energy, higher protein.
Oats: lower energy, higher fiber, good for starting does or light condition.
Soybean meal: high protein, excellent amino acid profile.
Canola meal: good protein source, slightly lower in energy than soybean meal.
Distillers grains: moderate protein and energy, high phosphorus.
Molasses: energy, palatability, and dust control.
Commercial goat feed: a complete or supplemental pellet formulated for goats.

Do not feed cattle or sheep concentrates to goats without checking mineral levels. Many contain additives or mineral levels that are inappropriate for goats. Copper is especially important. Goats need more copper than sheep, and some cattle feeds contain too much or too little for goats. Use a feed formulated for goats or have your mix custom formulated.

Step 5: Build the Ration

Start with the forage and calculate what it supplies. Then add concentrate to meet the remaining requirements. This is called the Pearson square method or the algebraic method when you have two feeds, but with multiple feedstuffs it is easier to use a spreadsheet or a ration balancing app.

Here is a practical example. You have a 150 pound doe producing 6 pounds of milk. Her dry matter intake target is 5 pounds. You have good quality mixed hay that tests at 12 percent crude protein and 0.58 Mcal of NEL per pound. You plan to feed 3.5 pounds of hay dry matter and 1.5 pounds of concentrate dry matter.

The hay supplies:

Protein: 3.5 times 0.12 equals 0.42 pounds
Energy: 3.5 times 0.58 equals 2.03 Mcal

The doe needs 1.03 pounds of protein and 4.3 Mcal of energy. The concentrate must supply:

Protein: 1.03 minus 0.42 equals 0.61 pounds
Energy: 4.3 minus 2.03 equals 2.27 Mcal

Over 1.5 pounds of concentrate, this means the concentrate needs:

Protein: 0.61 divided by 1.5 equals 0.41, or 41 percent protein. That is too high.
Energy: 2.27 divided by 1.5 equals 1.51 Mcal per pound. That is also too high.

The problem is that 3.5 pounds of hay is not enough dry matter, and the hay is not high enough quality. Increase the hay to 4 pounds and reduce concentrate to 1 pound. The hay supplies 0.48 pounds of protein and 2.32 Mcal of energy. The concentrate must supply 0.55 pounds of protein and 1.98 Mcal over 1 pound. That is 55 percent protein and 1.98 Mcal per pound, which is impossible.

The real solution is better forage or more total feed. If the doe can eat 5.5 pounds of dry matter, feed 4 pounds of hay and 1.5 pounds of concentrate. The hay supplies 0.48 pounds of protein and 2.32 Mcal. The concentrate needs 0.55 pounds of protein and 1.98 Mcal over 1.5 pounds, which is 37 percent protein and 1.32 Mcal per pound. A concentrate of 36 percent protein is achievable with soybean meal and corn, but it is a very high protein mix.

The simpler answer is to feed higher quality hay. If you switch to an alfalfa grass mix testing at 16 percent protein and 0.62 Mcal, then 4 pounds of hay supplies 0.64 pounds of protein and 2.48 Mcal. The concentrate needs 0.39 pounds of protein and 1.82 Mcal over 1.5 pounds, which is 26 percent protein and 1.21 Mcal per pound. A 24 to 26 percent protein concentrate is a standard dairy goat supplement.

This example shows why forage quality is so important. With poor forage, you need an expensive high protein concentrate. With good forage, a modest concentrate works. Always start with the best forage you can source.

Step 6: Balance Minerals and Vitamins

Once protein and energy are balanced, check minerals. Use a goat mineral mix or a custom mineral premix to meet calcium, phosphorus, salt, and trace mineral needs. If you are feeding legume forage, calcium is likely adequate and you may need to watch phosphorus. If you are feeding grass forage, both may be low.

Provide loose mineral free choice in addition to the ration. Goats are better at self regulating mineral intake than many people assume, but they will not eat a poorly formulated mineral. Offer a goat specific mineral mix and keep it clean and dry. Do not offer sheep mineral to goats, as it lacks adequate copper.

Step 7: Adjust for Stage of Lactation

The ration is not static. It must change through the lactation cycle.

Early lactation (0 to 8 weeks): The doe is at peak production and struggling to eat enough. Feed the highest quality forage available and increase the concentrate proportion to 50 to 60 percent of the ration dry matter. Feed small meals frequently to encourage intake. Watch body condition closely and increase energy if the doe is losing too much weight.

Mid lactation (8 to 24 weeks): Production is declining and intake has caught up. The doe can maintain condition on a lower concentrate proportion. Reduce concentrate to 40 to 50 percent of the ration. This is the time to let the doe regain some body condition, but do not let her get fat.

Late lactation (24 weeks to dry off): Production is low and the doe is often pregnant again. Reduce concentrate further to 20 to 30 percent. The fetus is growing rapidly in the last 6 weeks, so protein and minerals become more important. Do not let the doe get too fat, as this increases the risk of kidding problems.

Dry period: The doe should be dried off 6 to 8 weeks before kidding. Feed good quality forage with minimal or no concentrate. The goal is to maintain condition without excess weight gain. In the last 2 to 3 weeks before kidding, gradually introduce the lactation ration to allow the rumen microbes to adapt.

Step 8: Feed Management

How you feed matters as much as what you feed. Goats are selective eaters and will pick through a mixed ration, eating the tasty concentrate and leaving the forage. This leads to imbalances. Feed forage and concentrate separately or use a total mixed ration where everything is chopped and blended.

Feed at the same times every day. Goats thrive on routine. Feed after milking, when the doe is standing and relaxed. Provide enough bunk space so all does can eat at once. Bossy does will push others away from the feed, so watch for competition.

Weigh your feed. Scoops and flakes vary. Use a scale to weigh the concentrate for each doe or group, and weigh hay samples to calibrate your eye. This is the only way to know if the doe is actually getting the ration you formulated.

Common Mistakes in Goat Ration Formulation

Even experienced producers make feeding mistakes. The following are the most common problems seen on farms, along with how to avoid them.

Feeding by Eye Rather Than by Weight

A flake of hay varies in weight from 2 to 5 pounds depending on bale density and how it was baled. A scoop of grain varies with the feed and how it is scooped. When you feed by eye, the ration drifts. Some does get more than they need, others get less. Weigh feed for at least one feeding per week to calibrate your estimates.

Ignoring Forage Quality

Poor quality forage is the most common cause of poor milk production. A hay that looks green and smells good may still be low in protein and energy if it was cut late or rained on. Test your forage and buy hay by the test, not by the look. The cheapest hay is not the best value if it produces 2 pounds less milk per day.

Overfeeding Concentrate

More grain does not always mean more milk. When concentrate exceeds about 60 percent of the ration dry matter, rumen pH drops and fiber digestion suffers. The doe may go off feed, develop acidosis, and actually produce less milk. Increase concentrate gradually over 2 to 3 weeks and never make sudden changes.

Underfeeding Protein

Energy gets the attention, but protein is often the limiting factor in early lactation. A doe on high energy corn but low protein forage will not produce to her potential. The rumen microbes need ammonia to digest fiber, and the doe needs amino acids for milk protein. Balance protein and energy together, not separately.

Sudden Ration Changes

The rumen microbial population adapts to the diet over 2 to 3 weeks. A sudden change to a new hay or a higher grain ration disrupts digestion and can cause off feed, bloating, or acidosis. Make all changes gradually over 7 to 14 days. This is especially important at freshening and at dry off.

Forgetting Water

A doe that does not drink does not eat. Water intake drives dry matter intake, which drives milk production. Check water daily, clean troughs weekly, and provide water near the feed. In winter, break ice twice a day or use a heated waterer.

Feeding Whole Corn or Whole Grains

Goats do not chew grain thoroughly. Whole corn passes through the digestive tract largely undigested. Crack, roll, or steam flake grains to improve digestibility. Do not grind too finely, as dusty feed reduces intake and can cause digestive upset.

Using Cattle or Sheep Feed

Cattle feeds may contain non protein nitrogen like urea, which is poorly used by goats and can be toxic. Sheep feeds are formulated with low copper for sheep, and goats need more copper. Use feeds labeled for goats or have a custom mix formulated.

Neglecting Body Condition

The scale tells you about weight, but body condition scoring tells you about fat cover. A doe can lose condition while maintaining weight if she is gaining gut fill. Score body condition every 2 to 4 weeks and keep records. Adjust the ration before the doe becomes too thin or too fat.

Monitoring and Recordkeeping

A feeding program is a hypothesis. You formulate a ration, feed it, and observe the response. Without records, you cannot know if the ration is working. The following monitoring practices will tell you whether your ration is balanced.

Daily Observations

Walk through the herd every day. Look at each doe. Is she chewing her cud? Is her rumen full on the left side? Does she have good manure consistency? Is she bright and alert? These simple observations catch problems early.

Manure is a useful indicator. Normal goat feces are formed pellets or soft plops. Loose, watery manure suggests too much concentrate or a sudden ration change. Very dry, hard pellets suggest too little water or too much fiber. Manure with undigested grain suggests poor chewing or overfeeding.

Weekly Checks

Weigh feed refusals. If does are leaving feed, the ration is too large or unpalatable. If they are cleaning up the bunk in under 30 minutes, they may need more feed. Adjust the amount offered to achieve about 10 percent refusal for forage and near complete consumption of concentrate.

Check water intake if possible. A sudden drop in water consumption often precedes a drop in milk production. This can signal a water quality problem or an impending health issue.

Biweekly Checks

Body condition score each doe every 2 to 4 weeks. Track the trend. A loss of half a point in early lactation is normal. A loss of a full point or more is a warning. Gain in mid to late lactation should be gradual, not rapid.

Weigh milk production at least once a week. Keep a simple record of pounds per doe per day. A sudden drop of 10 percent or more is cause for investigation. Gradual decline following the normal lactation curve is expected.

Monthly Checks

Review your feed inventory and costs. Is the ration still economical? Are feed prices changing? Is the forage quality consistent between batches? Rebalance the ration when you bring in a new load of hay or a new batch of concentrate.

When to Adjust the Ration

Adjust the ration when you see a clear reason, not just because you think a change might help. Increase energy if body condition is dropping too fast or milk production is below target. Increase protein if milk protein percentage is low or if forage quality is poor. Decrease concentrate if does are getting fat or if manure is loose. Always make changes gradually and give the new ration 2 weeks before judging the result.

When to Call a Veterinarian or Extension Agent

Most feeding problems are solved by adjusting the ration. Some situations require professional help. Call your veterinarian if you see any of the following:

A doe goes off feed completely for more than 24 hours
A doe shows signs of ketosis, including sweet smelling breath, lethargy, or neurological signs
A doe has difficulty standing or appears weak
A doe has a fever, rapid breathing, or signs of pneumonia
A doe has diarrhea that is watery, bloody, or persists for more than 48 hours
A doe has a swollen udder, hard udder, or abnormal milk
A doe aborts or has a difficult kidding
Multiple does go off feed or show the same signs at the same time

Call your extension agent if you need help with:

Interpreting a forage test report
Calculating nutrient requirements for your specific herd
Identifying local feedstuffs and their typical nutrient values
Diagnosing a suspected mineral deficiency or toxicity
Designing a pasture or forage system for your operation

Extension agents have access to the latest research and can often run ration balancing software for you. They can also connect you with a ruminant nutritionist for complex situations.

Frequently Asked Questions

How much grain should I feed a milking goat per day?

The amount depends on the doe's size, milk production, and forage quality. A general starting point is 1 pound of concentrate per 3 to 4 pounds of milk produced, up to a maximum of about 1.5 pounds per feeding or 3 pounds per day for a large high producing doe. Divide the concentrate into two or three feedings per day to reduce the risk of acidosis. The exact amount must be calculated from the doe's requirements and the nutrient content of your forage. Start low and increase gradually over 2 to 3 weeks.

Can I feed my goats only hay and no grain?

Yes, but only if the hay is high enough quality to meet the doe's energy and protein needs. A dry doe or a doe in late lactation can often maintain condition on good forage alone. A lactating doe producing more than 2 to 3 pounds of milk per day will almost certainly need concentrate to meet her energy demands. High quality alfalfa hay can supply adequate protein, but it is rarely energy dense enough for peak lactation. Watch body condition closely if you feed forage only.

What is the best protein percentage for a dairy goat ration?

The ideal protein percentage depends on the stage of lactation and the doe's production level. Dry does need 10 to 12 percent crude protein. Does in early lactation producing 6 to 8 pounds of milk need 16 to 18 percent. Mid lactation does producing 4 to 6 pounds need 14 to 16 percent. Late lactation does need 12 to 14 percent. These are percentages of the total ration dry matter, not just the concentrate. A high producing doe on poor forage may need a 20 percent protein concentrate to bring the total ration up to the target.

How do I know if my goat is getting enough energy?

Watch body condition and milk production. If the doe is holding condition and producing at or above your target, she is getting enough energy. If she is losing more than half a body condition score in early lactation, she is not getting enough energy. If milk production is below the breed average for her stage of lactation, energy is the first thing to check. A doe that is thin and producing poorly needs more energy in the ration.

Why is my goat's milk butterfat low?

Low butterfat often points to a ration that is too high in concentrate and too low in effective fiber. The rumen needs physically effective fiber to maintain the right pH and produce the precursors for milk fat synthesis. Feed at least 40 to 50 percent of the ration dry matter as forage, and make sure the forage is chopped long enough to stimulate chewing. Avoid finely ground grains and excessive starch. Sudden ration changes can also cause a temporary drop in butterfat.

Should I feed a total mixed ration or separate forage and grain?

Both systems work. A total mixed ration ensures every bite is balanced and prevents selective eating, but it requires a mixer wagon and consistent forage quality. Feeding forage and concentrate separately is simpler and works well for small herds. The key is to feed the concentrate in small meals and make sure the doe eats her forage. If you feed separately, offer forage first and concentrate after, or feed concentrate in the milking parlor while the doe is being milked.

What minerals do milking goats need?

Milking goats need calcium, phosphorus, magnesium, potassium, sodium, chlorine, sulfur, copper, zinc, manganese, iodine, iron, cobalt, and selenium. The most critical for lactation are calcium and phosphorus, which are secreted in large amounts in milk. Offer a loose goat mineral mix free choice and check that the label includes selenium. The calcium to phosphorus ratio in the total ration should be about 1.5 to 2 to 1. Do not feed sheep mineral to goats because it is too low in copper.

How long before kidding should I dry off my goat?

Dry the doe off about 6 to 8 weeks before her expected kidding date. This gives the udder time to involute and repair, and it allows you to manage the doe's condition without the demands of lactation. During the dry period, feed good quality forage with minimal concentrate. In the last 2 to 3 weeks before kidding, gradually introduce the lactation concentrate to allow the rumen microbes to adapt. This reduces the risk of digestive upset at freshening.
