Feeding Dairy Goats: Nutritional Requirements, Common Feeds, and Best Practices

As someone who has raised dairy goats for several years, one of the most important aspects of goat care that I’ve learned is the importance of providing them with a balanced and nutritious diet. What dairy goats eat can have a significant impact on their health, productivity, and the quality of the milk they produce. In this article, I’ll be sharing what I’ve learned about feeding dairy goats, including their nutritional requirements, common feeds, and best practices for feeding them.

Nutritional Requirements of Dairy Goats

Before we dive into the specifics of what dairy goats eat, let’s first discuss their basic nutritional requirements. Like all animals, dairy goats require a balanced diet that provides them with the necessary nutrients, vitamins, and minerals to maintain good health and productivity. The four primary nutrients that dairy goats need are carbohydrates, proteins, fats, and fiber.

Carbohydrates are the primary energy source for dairy goats and provide them with the energy they need for daily activities and milk production. Proteins are essential for building and repairing body tissues and are particularly important for milk production. Fats are another important energy source for dairy goats and can also affect the flavor and texture of their milk. Finally, fiber is important for digestive health and helps keep the rumen functioning properly.

Common Feeds for Dairy Goats

Now that we know what nutrients dairy goats need, let’s take a look at some of the common feeds that are used to provide those nutrients. The specific feeds that you choose will depend on several factors, including the age and stage of lactation of your goats, their individual nutritional needs, and your own feeding preferences.

1. Hay

Hay is an essential component of a dairy goat’s diet, and it provides a vital source of fiber that promotes healthy rumen function and digestion. Good quality hay should be free of mold, dust, and other contaminants that can negatively impact the health of your goats. It’s important to ensure that your hay is harvested at the correct stage of maturity to ensure optimal nutrient content. The optimal stage of maturity varies depending on the type of hay, but in general, it’s best to harvest hay when it’s in the early bloom stage.

The type of hay that you choose will depend on your location and availability. Alfalfa is a popular choice for dairy goats because it’s high in protein and calcium, but it’s important to note that it can also be high in energy and may cause weight gain if not fed in moderation. Timothy hay is another common option that’s lower in protein and energy but high in fiber. Orchardgrass is a good choice for goats that are prone to bloat because it’s lower in protein and can be easier to digest. Finally, clover is a good choice for lactating does because it’s high in protein and calcium.

In addition to the type of hay, the quality of the hay is also important. Good quality hay should be green and leafy and should have a fresh, sweet smell. The hay should be free of dust, mold, and other contaminants, as these can cause respiratory issues and other health problems in dairy goats. To ensure that your hay stays fresh and nutritious, store it in a dry, well-ventilated area and protect it from moisture and pests.

It’s important to note that hay should be fed free-choice to dairy goats, meaning that they should have access to it at all times. This promotes healthy digestion and rumen function and helps prevent digestive issues like bloat and diarrhea. If you’re unsure about the quality of your hay or if you’re having trouble finding good quality hay in your area, consider working with a nutritionist or veterinarian who can help you develop a feeding plan that meets the nutritional needs of your goats.

2. Grains

While hay provides dairy goats with fiber, grains offer them energy, protein, and fats. Grains are a common supplement to hay in dairy goat diets, and they can help to meet their nutritional requirements for milk production. However, it’s important to note that grains should not be the primary source of nutrition for dairy goats, and their intake should be limited to prevent digestive issues.

Corn is a popular grain fed to dairy goats, and it’s a good source of carbohydrates. It can be fed whole or cracked, but it should never be fed as the sole source of grain because it’s low in protein and fiber. Oats are another commonly fed grain and are high in fiber and protein. They are also easy for goats to digest, making them a good choice for younger goats or goats with digestive issues.

Barley is a grain that is often used in dairy goat diets because it’s high in energy and protein. However, it can be more difficult for goats to digest, so it should be fed in smaller amounts. Wheat is another grain that can be fed to dairy goats, but it should be processed before feeding to improve digestibility. Like barley, wheat is high in energy and protein, but it’s low in fiber.

When feeding grains to dairy goats, it’s important to ensure that they are properly processed and balanced to prevent digestive upset. The grains should be ground or cracked to improve digestibility, and they should be fed in small amounts to prevent overconsumption. It’s also important to ensure that the grains are properly balanced with other nutrients in the diet to prevent deficiencies or imbalances. A nutritionist or veterinarian can help you to develop a balanced feeding program for your dairy goats that includes grains as a supplement to hay and other feeds.

3. Protein Supplements

Protein supplements are a valuable addition to a dairy goat’s diet, especially for lactating does. Soybean meal is one of the most commonly used protein supplements in dairy goat feed. It is a byproduct of soybean oil extraction and is a rich source of protein, containing around 44-50% crude protein. Soybean meal is also a good source of essential amino acids, making it a complete protein source. However, it should be noted that some goats may have an allergic reaction to soy, so it’s important to monitor them closely if you introduce soy-based feeds.

Cottonseed meal is another protein supplement that is often used in dairy goat diets. It is a byproduct of the cotton industry and is a good source of protein, containing around 41-46% crude protein. Cottonseed meal is also a good source of fiber and energy, making it a valuable addition to the diet of lactating does. However, it should be noted that cottonseed meal also contains gossypol, a toxic substance that can cause reproductive issues in some animals if consumed in large quantities. Therefore, cottonseed meal should be used in moderation and only under the guidance of a veterinarian or animal nutritionist.

Alfalfa pellets are also commonly used as a protein supplement for dairy goats. Alfalfa is a legume that is high in protein, containing around 15-20% crude protein. Alfalfa pellets are made by compressing alfalfa into small, easy-to-feed pellets. They are a convenient way to add protein and fiber to the diet of dairy goats. Alfalfa pellets can also be used to balance the protein content of the diet, especially during the late lactation stage when the protein requirements of lactating does are lower.

When feeding protein supplements to dairy goats, it’s important to ensure that they are properly balanced and that the goats are not consuming too much protein. Overfeeding protein can lead to health issues, such as urinary calculi and kidney damage. Therefore, it’s important to work with a veterinarian or animal nutritionist to determine the optimal protein requirements for your dairy goats based on their stage of lactation and individual needs.

4. Minerals and Vitamins

Minerals and vitamins are essential components of a dairy goat’s diet, as they play a crucial role in maintaining overall health and productivity. Here are some of the key minerals and vitamins that dairy goats need and their specific functions:

• Calcium: Calcium is essential for strong bones, milk production, and muscle function. Dairy goats require large amounts of calcium to support their high milk production levels, especially during early lactation when their calcium needs are the highest. Calcium can be provided through sources such as limestone, dicalcium phosphate, and oyster shell.
• Phosphorus: Phosphorus works together with calcium to build strong bones and teeth, as well as to support other bodily functions such as energy metabolism and cell growth. Phosphorus can be provided through sources such as dicalcium phosphate, monocalcium phosphate, and bone meal.
• Magnesium: Magnesium is necessary for proper nerve and muscle function, as well as for maintaining healthy bones and teeth. Magnesium deficiency can lead to symptoms such as muscle weakness, tremors, and even death in severe cases. Magnesium can be provided through sources such as magnesium oxide and magnesium sulfate.
• Zinc: Zinc is involved in many important bodily functions, including immune function, wound healing, and reproduction. Zinc deficiency can lead to symptoms such as reduced growth, poor immune function, and reproductive problems. Zinc can be provided through sources such as zinc sulfate, zinc oxide, and zinc methionine.
• Selenium: Selenium is an important antioxidant that helps protect cells from damage and supports immune function. Selenium deficiency can lead to symptoms such as reduced growth, muscle weakness, and reproductive problems. Selenium can be provided through sources such as selenium yeast, sodium selenite, and selenium-enriched alfalfa.
• Vitamin A: Vitamin A is important for vision, immune function, and reproductive health. Vitamin A deficiency can lead to symptoms such as poor growth, poor immune function, and reproductive problems. Vitamin A can be provided through sources such as alfalfa, sweet potatoes, and fish oil.
• Vitamin D: Vitamin D is necessary for proper bone growth and calcium absorption. Vitamin D deficiency can lead to symptoms such as weak bones and poor growth. Vitamin D can be provided through sources such as fortified feeds and exposure to sunlight.

To ensure that dairy goats are getting the right balance of minerals and vitamins, it’s important to work with a veterinarian or animal nutritionist to develop a diet that meets their specific needs. This may involve adding supplements or fortified feeds to their diet, or adjusting their feeding regimen to include more or less of certain foods depending on their nutrient content. Regular monitoring of body condition and milk production can also help ensure that dairy goats are getting the nutrients they need to stay healthy and productive.

Best Practices for Feeding Dairy Goats

In addition to providing the right types of feeds, there are several best practices that can help ensure that your dairy goats are getting the nutrition they need. Here are a few tips to keep in mind:

1. Provide fresh, clean water at all times.
2. Offer hay-free-choice to promote healthy digestion and rumen function.
3. Feed grains and supplements in small amounts to prevent digestive upset and to ensure that the goats are getting the nutrients they need.
4. Monitor the body condition of your goats regularly to ensure that they are maintaining a healthy weight and are not becoming too thin or overweight.
5. Avoid sudden changes to your goat’s diet, as this can cause digestive upset and lead to health problems.
6. Rotate hay sources regularly to ensure a diverse nutrient profile and prevent boredom.
