Management techniques of farming cattle in Spring

Spring is the peak period for cattle breeding, but the climate is changeable, and the morbidity and mortality of cattle are very high. Therefore, in spring, we should strengthen feeding and management, scientifically breed and conceive, ensure the safety of mother and child, and improve the reproduction rate.

The raising of empty cows

Each cow is fed about 50 grams of salt and 1 kilogram of blister-crushed concentrate such as barley, corn and soybeans every day. First drink water and then feed the grass, wait for the cattle to eat 50-60% full, feed the mixed concentrate, and then drink light salt water, wait for the cattle to rest for 15-20 minutes before coming out for grazing. Grazing and giving up enough water and night grass to allow cattle to drink and eat freely. When the cow is too fat, it can increase the amount of work and feed more coarse and succulent feed. If you are too thin, you will replenish more concentrate and green feed, and strive to achieve medium fat before mating.

Estrus cow breeding at the right time

After estrus, the cow is excited and restless, with a high tail and a white translucent mucus from the vulva, which can be pulled into a silk shape of 7cm and 8cm with hand pinch. The estrus of cattle lasts 18 hours, usually 12-22 hours, and ovulation occurs 10-15 hours after the end of estrus. Therefore, the suitable mating time for cows is: if they are in estrus in the morning, they will be mated at 8: 10 p.m. on the same day, and at 7: 8 a.m. the next day; if they are in estrus in the afternoon, they will be mated in the next morning and once in the afternoon or evening.

Induce oestrus and ovulation in cows

If the cow's genitals are normal but not in estrus or miss estrus, pregnant women's urine, diethylstilbestrol triad hormone and courtship diol can be used to induce oestrus ovulation, timely insemination and prevent empty pregnancy.

Carefully feed pregnant cows

Pregnant cattle to meet their own and fetal nutritional needs, so to provide high-quality formula feed, the formula is corn 30%, bean cake 20%, rice 15%, cottonseed cake 15%, rapeseed cake 5%, rice bran 15%, appropriate amount of bone meal and salt. 1-2kg concentrate per day, which is enough for green feed and ammoniated feed. Feed regularly, add less frequently, and drink warm water. On a sunny day, grazing in a place that is leeward and sunny is chosen to enhance the movement of cattle.

Prevent miscarriage and keep mother and child safe.

Cattle in the second trimester of pregnancy should gradually reduce the intensity of forced labor, and it is strictly forbidden to draw cold whips, do urgent work, turn sharp corners and make heavy labor. Stop labor to prevent miscarriage one month before delivery. If the cow early pregnancy vaginal mucus, constantly look back at the abdomen, restless; later breast enlargement, showing arched waist frequent micturition posture, abdominal pain is obvious, fetal movement stop is a sign of abortion, to timely treatment, progesterone 0.51g intramuscular injection, once a day, 4 days for 6 days. Cows with mild dystocia due to lack of exercise can be subcutaneously injected with oxytocin 60,100 units or diethylstilbestrol 10mg, and the effect of induced labor is better.

Strengthen the management of daily feeding environment

Fence house to plug loopholes, sunny shelter from the wind, not leaking rain, not damp. Remove cow dung frequently, change soil frequently, and change bedding grass frequently. Disinfect regularly with quicklime or plant ash. After the cattle go out for grazing, open the doors and windows in the pen for ventilation, brush the skin of the cattle every day to keep clean and enhance disease resistance.
