Plant by-products

Plant by-products can be fed to cows as a source of feed and fuel. Dairy cows include milking cows, replacement heifers, and dry cows. The total amount of byproducts fed to cows was 4,535,929 kg/cow/d.


Fruits are a great source of protein and vitamins for cows. These nutrients help them produce high-quality milk. They also contain dietary fiber and other nutrients beneficial to the cow’s health. In addition, they’re highly digestible. Cows can eat fresh, dried, and cooked fruits. Many common fruits are ideal for feeding to cows, including watermelon, apples, grapes, and oranges.


Vegetables for cows can provide a number of important nutrients. For instance, carrots can provide energy. It is common to feed cows as much as 35 pounds of carrots every day. While root crops are high in water, they should still be valued on a DM (dry matter) basis. This will ensure that they are equivalent in terms of weight. One vegetable cows should not consume is onion. Onions can be toxic to cows and are not recommended as human food.


The Food Standards Agency has confirmed six cases of sweet potato poisoning in cattle. The toxins are produced by fungi that can grow in damaged vegetables. This problem is not very common and is unlikely to affect human consumption. However, it is important to check the food before giving it to cows. Sweet potatoes are widely used in the US, parts of Asia and China, and are also a good source of vitamin C for humans.


Pears are not only good for humans, but they can also be eaten by cows without any ill effects. Pears are a good source of carbohydrates and fibre, and they also contain some protein. They are also high in vitamins C and K, as well as minerals like copper and potassium. Additionally, they contain polyphenol antioxidant compounds that prevent oxidation and inflammation in the body. Cows often suffer from low milk production when they are fed diets that do not contain enough essential nutrients.


Although not a common part of a cow’s diet, grapefruits can be a good source of vitamin C, zinc, and dietary fiber. Grapefruits are not dangerous to cows and can even lower their methane gas emissions. Cows can also consume ripe plums. However, there are some caveats about feeding cows these fruits. The pits of stone fruits should be removed before feeding them. Moreover, the fruit contains vitamins K, C, A, and B1. Additionally, it is high in calcium and magnesium.


In moderation, cows can eat strawberries, as long as they are free from contaminants. This is because cows are herbivores. They eat grass and other plant matter, which they break down into cellulose. Cellulose is a key source of energy for cows. However, in large quantities, strawberry consumption can be dangerous for cows, which is why cows should not eat it.


Oranges are the most popular human food that cows can eat, and they are an excellent source of vitamins and nutrients. They also have an antimicrobial effect, which is important for the health of the cows’ digestive tract. The peels of oranges are also rich in essential oils, which support healthy digestion and eliminate harmful bacteria.
