Misconception of dairy cow feeding
1. The mix ratio of concentrate feed and supplementary feed is unreasonable The protein feed uses more of a kind of cake, and it is rarely used with cotton aphid and peanut aphid. Minerals only pay attention to supplement calcium, phosphorus and salt, and do not do content determination, resulting in improper calcium or phosphorus ratio or insufficient supply and other issues. It is recommended that individual cattle farmers choose the better dairy cow concentrate feeds and supplementary feeds that are sold by regular feed manufacturers. They can also use dairy cows' special premixed feeds or concentrated feeds and formulate them according to their recommended formulas. 2. There are some feeds for green fodder and roughage. Some farmers raise green grass for the cows in summer and autumn, and only feed straw during winter. This is the wrong feeding method. The correct approach is to “combine dry and dry green and dry stems†in all seasons throughout the year and provide cows with a certain amount of root and dregs feed. This will not only increase the palatability of the diet but also satisfy the Milk nutrition needs of dairy cows. 3. Inaccurate proportion of concentrate feed and roughage cattle are herbivores and grass is the basic feed for dairy cows. In feeding, the mix ratio of dairy cow's concentrate feed and roughage is generally 5:5. 4. The feeding method is backwards. One is to feed part of the roughage first, then the concentrate feed and water are fed together; the second is that the concentrate feed, roughage and water are mixed in one feed. Both of these methods allow cows to shorten their feeding time and reduce the amount of saliva that enters the rumen. The third is to crush the roughage, which will cause rapid fermentation of the feed in the rumen. Long-term, it will easily lead to abnormal digestive function of dairy cows, milk production can not reach the normal level, and the proportion of milk fat is not stable. The better method is: (1) Determine the feed amount of concentrate feed and roughage according to the milk yield, etc., mix and feed, ie, fully mixed diet feeding method, and finally drink water. (2) After the first rough finish, first dry and then wet, when mixing materials with moisture can not afford dust, and finally drinking water. Try to make cows graze 7-8 hours a day, ruminates 7-8 hours, and rest 7-8 hours.
