Goat Pasture Rotation for Parasite Control: A Practical Guide

Key Takeaways

  • Pasture Rest is Paramount: A minimum of 60 to 90 days of pasture rest during warm weather is critical to allow infective Haemonchus contortus larvae (L3 stage) to die off naturally, as their survival is temperature and moisture dependent.
  • Strategic Grazing Height: Goats should be moved from a paddock when forage is grazed down to approximately 3 to 4 inches to avoid ingesting L3 larvae concentrated in the lower 2 inches of vegetation.
  • High-Density, Short-Duration Grazing: Implementing grazing periods of 1 to 3 days per paddock, especially during peak parasite seasons, concentrates manure and minimizes continuous exposure to larvae.
  • Multi-Species Rotation: Following goats with non-shared host species like cattle or horses acts as a biological vacuum, ingesting and eliminating goat-specific parasite larvae that cannot complete their life cycle in these animals.
  • Targeted Treatment with FAMACHA: The FAMACHA eye chart is a diagnostic tool to identify anemic goats (scores 4-5) due to barber pole worm infestation, enabling selective deworming and slowing anthelmintic resistance.
  • Integrated Management Practices: Mowing pastures post-grazing spreads manure, exposing larvae to desiccation, and feeding hay in elevated racks prevents direct ingestion of larvae from the ground.

Internal parasites, particularly barber pole worms (Haemonchus contortus), are the leading cause of death and production loss in goats across the United States. While dewormers have traditionally been the first line of defense, widespread drug resistance has made them increasingly ineffective. Goat pasture rotation offers a proven, cost-effective strategy to break the parasite life cycle, reduce reliance on chemicals, and improve overall flock health. This guide provides a complete, step-by-step system for implementing rotational grazing goats, covering pasture rest periods, grazing height, stocking density, and how to monitor success. It is written for small to mid-sized goat producers, homesteaders, and farmers transitioning to a more sustainable grazing system.

Understanding the Parasite Threat

Effective goat pasture management starts with understanding the enemy. Internal parasites, especially the barber pole worm, are not just a nuisance. They are a primary cause of poor weight gain, reduced milk production, anemia, and death. The economic losses from parasites in small ruminants are substantial, often exceeding the cost of any other health problem.

The Barber Pole Worm Life Cycle

The barber pole worm is the most dangerous parasite affecting goats. It is a blood-sucking worm that lives in the abomasum, the true stomach of the goat. The life cycle is direct, meaning it does not require an intermediate host.

  1. Adult worms inside the goat lay eggs.
  2. The eggs pass out of the goat in the feces.
  3. Under warm, moist conditions, the eggs hatch into larvae in the manure pat.
  4. Larvae molt and develop into the infective third stage (L3) over 4 to 7 days.
  5. L3 larvae migrate from the manure pat onto surrounding grass. They do not travel far, usually only a few inches.
  6. The goat ingests the L3 larvae while grazing.
  7. Larvae develop into adults inside the goat and begin laying eggs in about 3 weeks.

Why Goats Are Especially Vulnerable

Goats are more susceptible to parasites than sheep for several reasons. They are selective browsers, preferring to eat leaves, brush, and the tops of plants. However, when pasture is limited, they are forced to graze closer to the ground where infective larvae concentrate. Goats also have a weaker immune response to parasites compared to sheep, meaning they do not develop resistance as quickly.

The Problem with Dewormers

For decades, farmers relied on chemical dewormers to control parasites. This approach has failed. The overuse of dewormers has led to widespread drug resistance. On many farms, dewormers are now less than 50% effective. The American Consortium for Small Ruminant Parasite Control (ACSRPC) recommends a targeted approach to deworming rather than treating the entire flock. Treating every goat on a set schedule kills susceptible worms but leaves resistant worms to reproduce, accelerating the resistance problem.

How Goat Pasture Rotation Breaks the Parasite Cycle

Rotational grazing goats is a management system that controls parasites by breaking the life cycle. The core principle is simple: separate the goat from the parasite. By moving goats to a fresh pasture before they re-ingest significant numbers of larvae, and by allowing the previous pasture to rest long enough for larvae to die, you can dramatically reduce the parasite burden.

The Two Key Mechanisms

Goat pasture rotation works through two primary mechanisms.

1. Interrupting the Grazing Cycle

In a continuous grazing system, goats graze the same pasture all season. They constantly re-ingest infective larvae. The parasite load builds up in the pasture and in the goats. Rotational grazing goats moves them to a new paddock before they graze down to the danger zone where larvae are most concentrated. This reduces the number of larvae each goat ingests daily.

2. Using Time to Kill Larvae

The second mechanism relies on time. Infective larvae do not live forever. They require moisture and moderate temperatures to survive. By resting a pasture for a sufficient period, you allow the larvae to die off naturally. The length of the rest period depends on temperature and moisture. In hot, dry weather, larvae die quickly. In cool, moist weather, they can survive for months.

The Role of the Manure Pat

The manure pat is the center of the parasite universe. Eggs hatch and larvae develop inside the pat. The larvae then migrate out onto the grass. The speed of this migration depends on moisture. Larvae need a film of water on the grass to move. They cannot migrate in dry conditions. This is why parasite problems are worse in spring and fall when conditions are wet.

Designing Your Goat Grazing System

Before you move a single goat, you need a plan. A successful rotational grazing system requires careful thought about pasture layout, fencing, and water access.

Assess Your Land and Herd Size

Start by calculating your total pasture area and your herd size. A general rule of thumb for goats is 8 to 10 goats per acre for a continuous grazing system. With rotational grazing, you can often stock more densely because you are using the forage more efficiently. A good starting point is 10 to 12 goats per acre, but this depends heavily on rainfall, soil fertility, and forage quality.

Divide Your Pasture into Paddocks

The number of paddocks you need depends on your rest period and grazing duration. The formula is simple:

Number of Paddocks = (Rest Period in Days / Grazing Period in Days) + 1

For example, if you want a 60-day rest period and a 3-day grazing period, you need 21 paddocks. If you want a 30-day rest period and a 3-day grazing period, you need 11 paddocks. More paddocks give you more flexibility and better parasite control.

Permanent vs. Temporary Fencing

Permanent fencing is a significant investment but is the most reliable. High-tensile electric wire is a good choice for perimeter fencing. It is durable and effective at keeping goats in and predators out.

Temporary fencing is ideal for subdividing your pasture into smaller paddocks. Polywire and polytape with step-in posts are easy to move and allow you to adjust paddock sizes as needed. You can create a new paddock in 30 minutes or less.

Water Access in Each Paddock

Goats need access to clean, fresh water at all times. If you do not have a permanent water line to each paddock, you will need a portable system. A portable water tank on a trailer or a series of hoses and quick-connect fittings can work well. Some producers use a single water source and create paddocks that radiate out from it, giving goats access to water at the center.

How Long Should Pasture Rest Period Be for Goats?

The pasture rest period goats need is the single most important factor in parasite control. It is the time you leave a paddock ungrazed to allow parasite larvae to die. The required rest period varies with the season and weather conditions.

The 60 to 90 Day Rule

The general recommendation is to rest pastures for 60 to 90 days during the warm season. This is based on the lifespan of infective larvae. In warm weather, larvae die within 60 to 90 days. In cooler weather, they can live much longer.

Seasonal Adjustments

  • Hot, Dry Summer: Larvae die quickly in hot, dry conditions. A 30 to 60 day rest period may be sufficient. The heat and lack of moisture are lethal to larvae on the pasture.
  • Spring and Fall: These are the primary parasite seasons. Temperatures are moderate and moisture is plentiful. Larvae thrive. You should aim for the maximum rest period of 90 days.
  • Winter: Larvae survive the winter but do not reproduce. A rest period of 60 days is often enough. However, if you graze goats on winter pasture, they can still pick up larvae that survived from the fall.

How to Calculate Rest Periods

The rest period starts the day the goats leave the paddock. Mark the date on a calendar or in a record book. The paddock is ready for regrazing when the rest period has elapsed. This requires careful tracking. A simple whiteboard or a spreadsheet works well.

Grazing Duration: How Long Should Goats Stay in One Paddock?

The grazing duration is the time goats spend in each paddock. Shorter durations are better for parasite control. The goal is to move goats before they are forced to graze close to the ground where larvae concentrate.

The 1 to 3 Day Rule

During the peak parasite season, move goats every 1 to 3 days. This is called high-density, short-duration grazing. It mimics the natural behavior of wild herbivores, which move constantly and do not graze an area to the ground.

Grazing Height Matters

Do not let goats graze a paddock down to the dirt. The infective larvae are concentrated in the bottom 2 inches of the pasture. When goats graze below 3 to 4 inches, they ingest large numbers of larvae. Move them to a new paddock when the forage is grazed down to about 3 to 4 inches. This leaves a residue that protects the soil and reduces parasite pickup.

Adjusting for Forage Growth

In the spring, forage grows quickly. You may be able to graze a paddock for 3 days and then rest it for 60 days. In the summer, forage growth slows. You may need to lengthen the grazing duration or reduce the number of goats. The key is to match stocking rate to forage growth.

The Role of Stocking Density

Stocking density is the number of animals per unit area at a given time. It is different from stocking rate, which is the number of animals per acre for the entire grazing season. High stocking density is a key component of rotational grazing.

The Benefits of High Density

When you concentrate goats into a small area for a short time, they graze more uniformly. They are less selective and eat a wider variety of plants. This benefits the pasture because it prevents selective overgrazing of the most palatable plants. It also concentrates manure in a small area, which is then rested for a long period. This allows the manure to break down and the parasite larvae to die before goats return.

Calculating Stocking Density

A common recommendation is to stock at a density that allows goats to consume the available forage in 1 to 3 days. For example, if you have 20 goats that eat about 4% of their body weight per day, and they average 100 pounds each, they will consume about 80 pounds of forage per day. Over 3 days, they will consume 240 pounds. You need a paddock that contains at least 240 pounds of available forage, plus a residue of 3 to 4 inches.

Multi-Species Grazing: A Powerful Tool

One of the most effective strategies for goat parasite pasture management is multi-species grazing. Goats, cattle, horses, and sheep do not share the same internal parasites. The parasites that affect goats do not affect cattle, and vice versa.

How It Works

When you graze cattle after goats, the cattle will ingest goat parasite larvae. These larvae cannot survive in the cattle, so they die. The cattle act as a biological vacuum, cleaning the pasture of goat parasites. The reverse is also true. Grazing goats after cattle cleans the pasture of cattle parasites.

Designing a Multi-Species Rotation

The simplest approach is to alternate species in the rotation. For example, graze goats on a paddock for 2 days, then graze cattle on the same paddock for 2 days. The cattle will graze the forage down further and ingest goat parasite larvae. Then, the paddock rests.

If you do not have cattle, consider using horses. Horses are not affected by the same internal parasites as goats. Sheep share some parasites with goats, including barber pole worms, so grazing sheep after goats is not an effective parasite control strategy.

Pasture Management Beyond Rotation

Rotational grazing is the foundation of parasite control, but it is not the only tool. A comprehensive approach includes pasture mowing, manure management, and strategic hay feeding.

Mowing After Grazing

After goats leave a paddock, mow the pasture to a height of 3 to 4 inches. This serves two purposes. It spreads the manure pats, which exposes the parasite larvae to the sun and air. It also encourages new, palatable forage growth. Mowing is especially important in the spring when forage growth is rapid.

Harrowing or Dragging Pastures

Harrowing is a controversial practice in parasite control. It spreads manure and breaks up manure pats, but it also spreads parasite larvae over a wider area. In some cases, harrowing can increase the risk of parasite pickup because it spreads larvae onto more grass. If you choose to harrow, do it during hot, dry weather when larvae are likely to die quickly.

Feeding Hay Off the Ground

If you feed hay in the pasture, use an elevated hay rack or feeder. Feeding hay directly on the ground forces goats to eat near the soil where parasite larvae concentrate. Elevated feeders reduce parasite exposure and reduce hay waste.

The Use of a Sacrifice Lot

A sacrifice lot is a small, heavily grazed area where you keep goats during times of high parasite risk or when pasture is limited. It is called a sacrifice lot because you sacrifice the grass in that area to protect the rest of your pasture. Use a sacrifice lot during the hottest, most humid months when the parasite load is highest. Keep the lot dry and clean. Feed hay in elevated racks. The sacrifice lot will become bare dirt, but it prevents your main pastures from being overgrazed and contaminated.

The FAMACHA System for Targeted Deworming

Even with excellent goat pasture rotation, some goats will still need deworming. The key is to treat only the goats that need it, not the entire flock. The FAMACHA system is a tool for identifying goats that are anemic due to barber pole worm infection.

How FAMACHA Works

The FAMACHA system uses a laminated card with five color charts that match the color of the mucous membranes of the goat's lower eyelid. The colors range from red (healthy) to pale white (severely anemic).

  1. Category 1 (Red): Healthy, no deworming needed.
  2. Category 2 (Pink-Red): Healthy, no deworming needed.
  3. Category 3 (Pink): Borderline, monitor closely.
  4. Category 4 (Pale Pink): Anemic, deworm.
  5. Category 5 (White): Severely anemic, deworm immediately or cull.

When to Use FAMACHA

Score your goats every 2 to 3 weeks during the parasite season. This is a quick and easy process. Restrain the goat, gently pull down the lower eyelid, and compare the color of the mucous membrane to the FAMACHA card. Record the score for each goat.

The Benefits of Targeted Deworming

Targeted deworming, also known as selective deworming, has two major benefits. First, it reduces the amount of dewormer you use, saving money. Second, it leaves a population of susceptible worms in the goats and on the pasture. These susceptible worms dilute the resistant worms, slowing the development of drug resistance.

Fecal Egg Counting for Monitoring

Fecal egg count (FEC) is a quantitative measure of the number of parasite eggs in a goat's feces. It is a valuable tool for monitoring the effectiveness of your goat grazing system.

How to Collect Samples

Collect fresh fecal samples directly from the rectum or from the ground immediately after defecation. Place the samples in a clean, labeled container. Keep them cool and transport them to a veterinary lab or do the test yourself.

Interpreting Results

A fecal egg count of less than 500 eggs per gram (EPG) is considered low. A count of 500 to 2000 EPG is moderate. A count of over 2000 EPG is high and indicates a significant parasite burden. Young goats and lactating does will have higher counts than dry, mature goats. A count of over 5000 EPG in a kid is a serious concern.

The FEC Reduction Test

The fecal egg count reduction test (FECRT) measures the effectiveness of a dewormer. To perform this test, collect fecal samples from a group of goats, deworm them, and collect samples again 10 to 14 days later. If the dewormer is effective, the egg count should drop by more than 95%. If it drops by less than 90%, the worms are resistant to that dewormer.

Common Mistakes in Rotational Grazing for Parasite Control

Many producers make mistakes when they first start rotational grazing. Here are the most common pitfalls and how to avoid them.

Mistake 1: Rest Periods That Are Too Short

The most common mistake is not resting pastures long enough. A 30-day rest period is not enough to kill parasite larvae in the spring or fall. You must rest pastures for 60 to 90 days during the warm season. If you are not seeing results, extend your rest periods before making any other changes.

Mistake 2: Grazing Too Low

Forcing goats to graze a pasture down to 2 inches or less is a recipe for disaster. The bottom 2 inches of the pasture is where the infective larvae are concentrated. Move goats to a new paddock when the forage is at 3 to 4 inches. This is a non-negotiable rule.

Mistake 3: Using the Same Paddock Size All Year

Forage growth varies throughout the season. A paddock that provides 3 days of grazing in the spring may only provide 1 day in the summer. You must adjust paddock size based on available forage. Use temporary fencing to make paddocks larger or smaller as needed.

Mistake 4: Ignoring the Manure Pats

Manure pats are the source of future parasite problems. If you do not mow or harrow to spread the manure, the larvae will concentrate around each pat. This creates a patchwork of high-risk areas in your pasture.

Mistake 5: Deworming Every Goat

Blanket deworming is a major contributor to drug resistance. Stop deworming every goat on a schedule. Use the FAMACHA system to identify and treat only the goats that need it.

Mistake 6: Not Keeping Records

You cannot manage what you do not measure. If you do not record rest periods, grazing dates, FAMACHA scores, and fecal egg counts, you are flying blind. Good records allow you to make data-driven decisions and identify problems early.

Decision Thresholds: When to Act

Knowing when to act is critical. Here are some decision thresholds to guide you.

When to Deworm an Individual Goat

Deworm a goat when its FAMACHA score is 4 or 5 (pale pink or white). Also deworm goats that are showing clinical signs of parasitism, such as weight loss, diarrhea, or bottle jaw (swelling under the jaw). Do not deworm goats with a FAMACHA score of 1, 2, or 3.

When to Change Your Rotation Plan

If you are seeing high fecal egg counts in your goats despite following a 60 to 90 day rest period, you need to change your plan. Consider extending rest periods to 90 days or longer. You may also need to increase the stocking density and shorten the grazing duration. If parasites are still a problem, consider multi-species grazing or a longer break from grazing the pasture altogether.

When to Call a Veterinarian

You should call a veterinarian if you have goats that are severely anemic, if you suspect a dewormer failure, or if you have a high number of goat deaths. A veterinarian can perform a fecal egg count reduction test to determine the effectiveness of your dewormer. They can also help you identify which dewormer is still effective on your farm.

When to Cull

Culling is a difficult but necessary part of parasite management. Some goats are genetically predisposed to parasite susceptibility. They will require constant deworming and will never thrive. These goats should be culled. If a goat needs deworming more than 3 to 4 times per year, it is a candidate for culling. Culling susceptible goats improves the overall health and resilience of your herd.

Record Keeping for Pasture Management

A simple record-keeping system is essential for successful goat pasture rotation. You need to track pasture use, rest periods, and goat health.

Pasture Records

For each paddock, record:

  • Paddock number or name
  • Date goats entered the paddock
  • Date goats left the paddock
  • Number of goats and their average weight
  • Rest period (date the paddock is ready for regrazing)
  • Forage height before and after grazing
  • Any mowing or harrowing dates

Goat Health Records

For each goat, record:

  • FAMACHA score at each scoring session
  • Deworming dates and products used
  • Fecal egg count results
  • Body condition score
  • Weight

Using a Spreadsheet or Notebook

A simple spreadsheet can handle this task. Create a tab for pasture records and a tab for goat health records. Alternatively, use a notebook and keep it in the barn. The key is consistency. Record data at the same time each day or week.

Seasonal Management Calendar

A year-round approach to goat pasture management is essential. Here is a seasonal calendar to guide you.

Spring (March to May)

Spring is the start of the parasite season. The weather is warm and wet, and larvae are hatching. This is a critical time for goat pasture rotation.

  • Begin rotational grazing as soon as forage growth starts.
  • Use a 60 to 90 day rest period.
  • Start FAMACHA scoring every 2 to 3 weeks.
  • Mow pastures after grazing to spread manure.
  • Monitor forage growth and adjust paddock sizes.

Summer (June to August)

Summer is the high-risk season for barber pole worms. The heat and humidity are ideal for larvae development.

  • Maintain the longest possible rest periods (90 days).
  • Consider moving goats to a sacrifice lot during the hottest, most humid weeks.
  • Continue FAMACHA scoring.
  • Check water sources daily.

Fall (September to November)

Fall is the second peak parasite season. The weather cools and moisture returns.

  • Continue rotational grazing with 60 to 90 day rest periods.
  • Watch for a second wave of parasite problems.
  • Perform a fecal egg count to assess the herd's parasite burden.
  • Deworm any goats that need it before winter.

Winter (December to February)

Winter is the low-risk season. Larvae survive but do not reproduce.

  • You can lengthen the grazing duration to 5 to 7 days per paddock.
  • Rest periods can be shortened to 60 days.
  • Feed hay in elevated racks.
  • Use a sacrifice lot if pasture is covered in snow or mud.
  • Plan your spring grazing system and make any needed fence repairs.

Building Genetic Resistance in Your Herd

Rotational grazing is a management tool, but genetics also play a role in parasite resistance. Some goats are naturally more resistant to parasites than others. They are able to mount a stronger immune response and carry lower parasite burdens.

Selecting for Resistance

When selecting breeding stock, look for goats that maintain good body condition and FAMACHA scores without frequent deworming. Do not breed goats that require constant deworming. Over time, you can build a herd that is more resistant to parasites.

The Role of Nutrition

Good nutrition supports the goat's immune system. A goat that is receiving adequate protein, energy, and minerals is better able to fight off parasites. Provide a balanced mineral supplement and ensure goats have access to high-quality forage. Protein is especially important. Goats that are protein-deficient are more susceptible to parasites.

Integrating Goat Pasture Rotation with Other Control Methods

Rotational grazing is a powerful tool, but it works best as part of an integrated parasite management program.

Copper Oxide Wire Particles

Copper oxide wire particles (COWP) are a treatment option for barber pole worms in goats. They are administered orally in a bolus. They are not a traditional dewormer but work by releasing copper in the abomasum, which is toxic to the worms. COWP can be useful for treating individual goats, but they do not replace good pasture management.

Biological Control

There is ongoing research into biological control methods for parasites, such as the use of nematophagous fungi that feed on larvae in the manure. These products are not widely available yet, but they may become a future tool.

The Importance of Biosecurity

When you bring new goats onto your farm, quarantine them for at least 30 days. Do not let them graze with your existing herd. Treat them for parasites and monitor their fecal egg counts before introducing them. This prevents the introduction of drug-resistant worms to your pasture.

Common Questions About Goat Pasture Rotation

How many acres do I need for rotational goat grazing?

The number of acres depends on your herd size, climate, and forage quality. A general rule is 10 to 12 goats per acre with rotational grazing, but you may need more in dry climates or less in areas with excellent forage. The key is to match the number of goats to the available forage and use temporary fencing to adjust paddock sizes.

How long does it take for parasites to die in a pasture?

The lifespan of infective larvae depends on temperature and moisture. In hot, dry weather, larvae can die in 30 to 60 days. In cool, moist weather, they can survive for 6 months or more. The 60 to 90 day rest period is a safe guideline for the warm season.

Can I graze goats with sheep?

Yes, but it is not a parasite control strategy. Goats and sheep share many of the same parasites, including barber pole worms. Grazing them together can increase the parasite load on the pasture. If you graze them together, you must be even more diligent about rest periods and monitoring.

What is the best dewormer for goats?

There is no single best dewormer. Widespread drug resistance means that the effectiveness of dewormers varies from farm to farm. The only way to know which dewormer works on your farm is to perform a fecal egg count reduction test. Your veterinarian can help you interpret the results.

How often should I move my goats?

During the peak parasite season, move goats every 1 to 3 days. In the winter, you can extend the grazing duration to 5 to 7 days. The key is to move them before they graze below 3 to 4 inches.

Should I mow my pasture after the goats leave?

Yes. Mowing after grazing spreads manure pats and exposes parasite larvae to the sun. It also encourages new forage growth. Mowing is one of the most effective pasture management practices you can adopt.

How do I know if my dewormer is working?

The best way is to perform a fecal egg count reduction test. Collect fecal samples from a group of goats, deworm them, and collect samples again 10 to 14 days later. If the egg count drops by more than 95%, the dewormer is effective. If it drops by less than 90%, the worms are resistant.

What is a sacrifice lot?

A sacrifice lot is a small, heavily grazed area where you keep goats during times of high parasite risk or when pasture is limited. It protects your main pastures from overgrazing and contamination. Feed hay in elevated racks and keep the lot as clean and dry as possible.

Frequently Asked Questions

What is the minimum pasture rest period for goats to control parasites?

The minimum rest period is 30 days, but this is only safe during hot, dry weather when larvae die quickly. For reliable parasite control, use a 60 to 90 day rest period during the warm season. In the spring and fall, aim for the maximum 90 days. In the winter, a 60 day rest period is usually sufficient.

Can I use rotational grazing to eliminate the need for dewormers?

Rotational grazing can dramatically reduce your need for dewormers, but it may not eliminate it entirely. Some goats will still need targeted treatment. The goal is to reduce dewormer use to a minimum and to use it only on the goats that need it, based on FAMACHA scoring and fecal egg counts.

How do I start rotational grazing with a small herd of goats?

Start by dividing your existing pasture into 4 to 6 paddocks using temporary fencing. Move your goats every 3 to 7 days, depending on forage growth. Track rest periods and aim for 60 to 90 days of rest. As you gain experience, you can adjust the number of paddocks and the grazing duration.

How do I know if my pasture rest period is long enough?

The best way to know is to monitor fecal egg counts in your goats. If the counts remain low throughout the season, your rest periods are adequate. If the counts are high, extend the rest periods. You can also perform a pasture larval count, but this requires specialized laboratory services.

What should I do with goats that are severely anemic?

Separate a severely anemic goat from the herd and move it to a clean, dry pen. Deworm it immediately. Provide high-quality hay and fresh water. If the goat does not improve within a few days, or if it is very weak, call a veterinarian. In many cases, a severely anemic goat is a candidate for culling.

Does rotational grazing work for goats on small acreage?

Yes, rotational grazing works well on small acreage. You can divide a single acre into several paddocks using temporary fencing. The key is to adjust the paddock size and grazing duration to match the available forage. On very small acreage, you may need to rely more on hay feeding and a sacrifice lot.

How does stocking density affect parasite control?

Higher stocking density for a short duration is better for parasite control. When goats are concentrated, they graze more uniformly and are moved before they graze too low. The high concentration of manure in a rested paddock allows the larvae to die before the goats return.

What is the best way to manage manure in a rotational grazing system?

Mowing after grazing is the best way to manage manure. It spreads the manure pats and exposes larvae to the sun. Avoid harrowing during wet weather because it spreads larvae onto more grass. In a rotational system, the long rest period is the primary manure management tool.
