First, predatory milking: General cows lactation period of 305 days, but due to cow age, parity, lyrics and feeding levels and other factors, sometimes the prolonged or shortened lactation period. At present, some dairy cows, no matter what the circumstances, have been squeezed from post-natal to no milk, only to stop milking. The negative effect of this is serious. One is that cows consume excessive nutrients in the body, causing the cows to lose their estrus and have a sexual cycle disorder, making it difficult to match the pregnancy. The second is that the dairy cows have large physical strength and are not easy to recover in a short period of time, affecting the increase in the amount of lactation in the next fetus.
Second, the initial small individual: data show that the initial weight of dairy cows should reach 350 to 400 kg, 10 to 11 times the calf's birth weight, many dairy cows in the yak was born 18 months old, weight Only 250 to 300 kilograms on the frozen, the first child often have dystocia, had to carry out artificial midwifery, causing more rupture of the vulva, secondary to endometritis, affecting the normal reproduction of the next fetus. Therefore, it is necessary to overcome the impatience and strengthen the breeding and management of yak and bred cattle so that the ideal body weight can be achieved before mating, so as to adapt to the cold match.
Third, dry milk reduction: Dairy cows after lactation, body nutrient loss, need to recover in dry milk to make up. Some dairy cows mistakenly believe that no milking should be fed worse, and that the concentrate is significantly reduced when compared to lactation. Since the nutrition is not compensated at this stage, the cows are in a lower condition before delivery and the calves are time-consuming. Weak, cows have low milk production. It can be seen that except for a few days after the dried milk, the dairy cows have reduced the amount of concentrate, and it is advisable that the amount of dry cow milk be 0.8% to 0.9% of the weight of the cow. Poorly bred dairy cows should be slightly lower than the lactation period to meet the needs of cows for protein, minerals, and vitamins during this period. The amount of concentrate feeding can be appropriately reduced a few days before delivery to facilitate the normal delivery of cows.
Fourth, little feed green feed: Most dairy cows feed wheat straw all year round, feeding only a small amount of green feed in July, August and September, far from meeting the needs of dairy cows for green feed. Should try to collect grass and crop stems and leaves removed to feed cows, the rest can be dried or silage, so that it is busy to fill, always do not lack of green.
Fifth, yak raising: Most dairy cows separate the newborn calf from the cow with a tethered neck, which not only limits the calf activity, but also seriously hinders the calf's growth and development, which is extremely harmful to calves. The newborn calf bar is free to move and is regularly fed by the breeder, which facilitates the management of the cows and helps increase the milk production of the cows.
Sixth, the trough sees the pile: The so-called trough sees the pile, is in regardless of four seasons throughout the year, feeds the cow when the cow gnaws on the trough or in the outer stake, does not allow the cow to move, like raises the yellow cattle the way Dairy cows, often appear cows estrus is not obvious, estrus is difficult to match the pregnancy, cows postpartum discharge slowly, individual cattle clothing, cows poor body, weak disease resistance and other adverse signs. In the improved method, the cow has a chain on the neck and the neck is tied on the trough when the trough is fed so that the cow can freely eat and rest. After feeding during the day, untie the trough on the chain to move the cow to any field. Maintaining sufficient exercise for dairy cows has a very important role in promoting the metabolism of dairy cows, increasing appetite, maintaining normal reproduction, and preventing diseases.
Seventh, do not brush cattle body: dairy cow skin metabolism is strong, sensitive to external dust reaction, when the hair is attached to dry faeces, dust, etc., the cows feel uncomfortable, commonly used tongue, use the body to wipe the wall, groove and other ways to lift the body Itching, along with the consumption of nutrients and the loss of appetite, seriously affects the health of dairy cows. In order to keep the body clean and tidy, brush once daily with a brush, comb from head to neck or even body limbs to maintain the normal physiological function of the cow's skin.
VIII. Non-disinfection awareness: Under good husbandry conditions, raising dairy cows rarely gets sick, but in rough feeding environments, dairy cows have poor constitution, weak disease resistance, and bacteria easily invade the bovine body, causing cows to become ill. To do a good job of disinfection, winter and spring disinfection of the cowshed, feeding environment once a week. Summer and autumn are sterilized twice a week. A disinfection tank shall be set up in front of and out of the door of the breeding cows to prevent invasion by foreigners. Do a good job of disinfection while doing feed, drinking water, clean, strictly prohibited feed mildew.
Nine, Yak is not scientific: As the cows do not tie cattle nose, no nose ring, dairy cattle households to facilitate the use of rope angle, some cows small, can not hold back, use the rope tied neck. Practice has proved that these two methods have drawbacks and can easily hurt the skin of cattle. Scientific bovine cattle are tethered to the cow's neck. When the cow is fed, the chain is attached to the groove chain and fed in a fixed slot. After feeding, the open chain releases the movement.
Second, the initial small individual: data show that the initial weight of dairy cows should reach 350 to 400 kg, 10 to 11 times the calf's birth weight, many dairy cows in the yak was born 18 months old, weight Only 250 to 300 kilograms on the frozen, the first child often have dystocia, had to carry out artificial midwifery, causing more rupture of the vulva, secondary to endometritis, affecting the normal reproduction of the next fetus. Therefore, it is necessary to overcome the impatience and strengthen the breeding and management of yak and bred cattle so that the ideal body weight can be achieved before mating, so as to adapt to the cold match.
