Fat is an indispensable material for dairy cows' milk formation. Sufficient fat supply is a necessary guarantee for dairy cows to promote milk production. Fat intake should be appropriate The content of fat in the dairy cow diet should not exceed 7% of the dry matter of the diet, and the supplement amount is generally 3% to 4%. Calculate the amount of fat to add accurately The amount of fat that cows need depends on the amount of buttermilk synthesis. If a dairy cow produces 36 kilograms of fresh milk per day, the milk fat rate is 3.5%, and the fat content in one day is 1.27 kilograms, to maintain the cow's normal condition and continuous production level, 1.27 kilograms of fat should be added to the diet. Feeding different sources and types of fat Do not use only one type of fat in production. For example, the only fat that uses soybean as a diet can cause an excess of degradable protein in the rumen, affecting feed intake. Gossypol poisoning occurs when cottonseeds are fed more than 3.6 kilograms per day, resulting in reduced visceral bleeding and reproductive performance. Liquid fats are not suitable for the feed of lactating cattle. Pay attention to the interaction between fat and roughage When adding fat, consider the type of roughage that makes up the diet. When corn silage is used as the main forage, only the addition of cow and sheep oil can increase milk production. Wolfberry and cottonseed have a good synergy and can accelerate the digestion of cottonseed. Feeding fat should be gradual Gradually increasing fat intake can avoid poor palatability. He began to feed 1/3 first and fed the whole amount in 3 stages. Generally it takes 3 weeks to 4 weeks. You can gradually add fat during the dry period. It usually takes 3 days for cows to adapt to fat. Compared with other feeds, cows are slower to eat fat. It is best to add fat to the fully mixed diet and mix thoroughly with the other ingredients. If this is not possible, feed as much fat and feed as possible.
