Dairy cow feeding 5 bogey
First, the cow as a yellow cattle raise. Many farmers raise cows as yellow cattle, and their husbandry and management are extremely extensive. The roughage they feed to dairy cows is mainly dry corn stalks, leaves, wheat straw, rice straw, etc. The concentrate feed is mainly “three-in-a-kind†(bean meal, bran, cornmeal), resulting in a serious lack of nutrition for dairy cows, which in turn leads to postpartum paralysis. , No estrus, dystocia, no placental clothing, etc., have seriously affected the normal production performance of dairy cows, shortened the life of dairy cows, and caused significant economic losses. Feeds for dairy cows need to be as diverse as possible to achieve good palatability and complete nutrition, so as to meet the needs of cows and treat cows as yellow cattle.

Feeds for dairy cows should be as diverse as possible to achieve good palatability and complete nutrition to meet the normal physiological needs of dairy cows. Second, excessive addition of salt in concentrate feed. Some breeders have added 3-4% of salt to concentrates in order to allow the cows to drink more water to reach the goal of prolific milk production. Little do they not know that doing so can easily increase the burden on the cow’s kidneys and cause cows’ salt poisoning. Moreover, although this method can increase the milk production of dairy cows slightly, it will reduce the specific gravity and fat percentage of milk, which is not worth the candle. The proportion of salt in concentrates should be controlled at 0.7-0.8%. In order to supplement the deficiency of salt in concentrate feed, a trough can be set in the dairy stadium, and salt or raft salt bricks can be placed in the trough for the dairy cows to feed freely. Third, cows with small individuals. The initial age of dairy cows should be 18-20 months and the body weight should be about 380 kg. The two indicators should be considered comprehensively to achieve sexual maturity and maturity. Many rearing households do not pay attention to the rearing and management of dairy cows. At 18 months of age, the cows weigh only 250-300 kg. If they are bred at this time, the cows are often difficult to produce, and as a result, midwives have to be carried out, resulting in damage to the birth canal. Secondary endometritis, not only affect the normal reproduction of the next child, but also affect their own growth and milk production performance. Therefore, attention must be paid to strengthening the management of breeding calves and bred cattle. Fourth, predatory milking. A lactation cycle is typically 305 days for cows and 60 days for dry milk. Due to factors such as cow milk production, age, parity, lyrics and feeding level, the dry period of dairy cows should be appropriately extended or shortened, but the shortest period should not be less than 45 days. Some breeders have been predatory milking for the benefit of their eyes, and have been squeezed until the cows are not producing milk. The negative effects caused by this are serious: First, the cows consume excessive nutrients in the body, affecting the development of the fetus in the body and increasing the milk yield in the next lactation cycle; the second is causing the cows to have late estrus or estrus after calving, and the sexual cycle is disordered. . Dry milk period is indispensable for dairy cows, and dry cows should be properly extended for cows with poor lye, so that cows have sufficient rest and buffering time to make up for their body.
