Let's look at what protective fats are. The protective fats are found on the surface of oils and fats. They are substances that are difficult to break down in the rumen and protect fat. In order not to be destroyed, it will be fully absorbed, digested, and utilized by the intestines after it enters the small intestine. Protective cows themselves can not only increase milk production and improve milk quality, but also reduce the stress of dairy cows, and can also increase the reproductive performance of dairy cows. The benefits of protective fat-fed cows are a new technology, and the precautions for feeding cows with protective fats: 1, choose the type of protective fat products: In the practical application of protective fat feeding cows, protective fatty products should be selected short carbon chain fatty acids, protective carbon chain short fatty acids into the intestine to absorb well, high utilization . Also pay attention to the choice of unsaturated fatty acids, better absorption than saturated fatty acids, the effect is good. If the fat used in production is not coated, special attention should be paid when feeding cows: one is to control the added amount; the other is to increase the content of calcium and magnesium in the diet. 2. Control the amount of added: because adding too much will cause waste and reduce the feed intake of the cow, which will reduce the production performance of the cow. Generally, the total fat content in dairy cows' diets reaches 5%-6%, and the cow's utilization rate is the best. When the amount is more than 6%, there will be side effects on the production of dairy cows. On the contrary, when the amount is small, if it is less than 3%, the effect is not obvious. 3, add time to be timely: After calving, the consumption of dairy cows is large, and the feeding of fat itself is also a kind of stress, so the cows should not be added in the short term after delivery. Should be fed 3 to 5 weeks after the birth, the effect of stress after feeding is smaller, and milk production will temporarily drop, but then the milk production will gradually increase. In the hot season, it is better to enter the lactation period and can prolong the peak period of milk production. It will increase milk production throughout the lactation period. However, the effect of lactation to the late stage is not obvious, and there is no need to use this protective fat. 4. The composition of the diet should be reasonable: Feed cows protective fat, should be fed high quality hay, so that the amount of fiber to meet the requirements, can promote the rumen more acid production, so as to give full play to the role of fat, dairy cows milk production and milk fat to Significantly improved, dry matter content in the diet of 17% of the level, 21% of acid washing fiber. 5. Distinguish applicable objects: Dairy cattle protective fat is mainly suitable for high and middle-producing dairy cows. It is not suitable for low-yielding dairy cows. The feeding effect is not good. If the average cow's milk yield is lower than 25.5 kg, no need to add oil, the milk output exceeds this average. Values ​​can be added to increase the energy of the diet to meet its production needs. Practice has proved that dairy cows whose milk fat percentage is less than 3.5% have good use effect. When the milk fat percentage is higher than 3.5%, the effect of adding is not obvious. 6, step by step: feeding cows protective fat, should gradually increase the amount of feeding not to reach the required number of steps, you can avoid the problem of poor palatability, should be divided into three stages to the required quantitative, generally after 3 weeks - 4 weeks to use Full amount, this will not significantly affect the palatability of dairy cows. Through this article in more detail summarized how to feed dairy cows protective fat, so that cows more fully absorb, digest and use, and ultimately to improve reproductive performance, improve milk quality and increase milk volume, provide better for cattle raisers The proceeds.
