Unreasonable ratio of concentrate feed and supplementary feed
There are many kinds of cakes used in protein feed, and cotton aphids and peanut vinegar are rarely used together. 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-raising households should use the concentrated cow fodder and supplementary feeds sold by regular feed manufacturers. They may also choose cow premixed fodder or concentrated fodder, and formulate their own according to the recommended formula.
Green feed and rough feed
Some breeders feed grasses in summer and autumn and only feed straw in winter. This is a 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.
Inaccurate proportion of concentrate and roughage
Cows are herbivores and grasses are basic feed for dairy cows. In feeding, the proportion of dairy concentrate and roughage is generally 5:5.
Feeding method behind
One is to feed part of the roughage first, then feed the concentrate and water. The second is concentrated feed, roughage and water 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 correct method is to determine the feed amount of the concentrate feed and the roughage feed according to the milk production and other conditions, feed after mixing and mixing, that is, the fully mixed diet feeding method, and finally drinking water.
After the first rough finish, first dry and then wet, when the mix can not afford dust and finally drinking water. As far as possible, the cows grazing every day for 7 hours to 8 hours, ruminations for 7 hours to 8 hours, and rest for 7 hours to 8 hours.
