Nowadays, many individual breeders do not have the right way to feed, making it difficult to raise the economic benefits of raising cattle. Mainly in the following areas:
Awareness of detoxification is not strong Many dairy cows believe cattle have strong disease resistance and do not need to pay attention to it. As a result, cows often die. We must conscientiously do a good job of disinfection, winter and spring weekly disinfection of the cowshed and the surrounding environment, summer and autumn disinfection twice a week, and do feed, drinking water hygiene, prevent mildew feed.
Anxious to achieve a lot of dairy cows in the yak is not born 18 months old, when the weight is only 250 kg when the mating, the first child often have dystocia, rupture of the vulva, secondary endometritis, affecting the normal reproduction of the next child . Therefore, the cattle-raising households can't be eager to seek success, and the feeding tubes for yaks and bred cattle should be strengthened to reach 350-400 kg (about 10 times as much as the initial weight of yak).
Excessive Milking General dairy cows have a lactation period of 305 days, but due to factors such as cow age, parity, sensation and feeding level, sometimes the lactation period is prolonged or shortened. Some dairy farmers, from the post-partum period has been squeezed until no milk to stop milking, resulting in excessive consumption of nutrients in dairy cows, resulting in cows estrus is not obvious, sexual cycle disorders, more difficult to suffer from pregnancy and affect the increase in lactation. Therefore, milk must be milked during the lactation period so that the cows have enough time to make up for the loss of nutrients in the body and lay the foundation for the higher milk yield of the next baby.
During the dry period, the dairy cows in the milk-reducing period go through the calving of the puerpera, and the nutrient loss in the body is increased. In addition, the need for nutrition during pregnancy and embryonic development needs to be restored during the dry period. Many dairy cows mistakenly believe that the milk should be fed without milking. If it is worse, the amount of fine feed is drastically reduced, which results in a lower level of sensation before labor, and it takes time to produce calves. The calf's constitution is weak and cows have low milk production. This shows that in addition to just a few days after the dry milk and a few days before the temporary production of dairy cows to reduce the amount of feed, the dry period of feeding the amount of cows accounted for 0.8% -0.9% of body weight is appropriate.
The use of piles to raise most dairy cows raises the cows with ropes and necks regardless of the season. Never allowing the cows to exercise, not only limits the calf activity, but also seriously hinders the growth and development of calves, resulting in difficult labor for dairy cows. No more than fetal clothing, estrus is not obvious, bad health and other adverse reactions. Therefore, the calves should be allowed to move freely in the calf pens and feed regularly.
