Feeding and management techniques of pregnant cattle in winter

Autumn is the peak period for cattle breeding. In the severe winter when the forage grass wilts, pregnant cows are not only attacked by the cold, but also provide all the nutrients needed for the growth and development of the fetus. In the harsh climate conditions, if pregnant cattle are not properly raised, especially in sudden changes in temperature, it is very easy to lead to the decline of pregnant cows' physique and even lead to the death of both mothers and offspring. For this reason, the following measures should be taken for pregnant cattle.

Renovate the fence house and keep warm against the cold

Pregnant cattle should have separate barns to avoid crowding, kicking and miscarriage. Fence house to plug loopholes, sunny shelter from the wind, not leaking rain, not damp. Often change the bedding grass, in a sunny noon, herding cattle to outside activities and basking in the sun.

Strengthen nutrition and raise carefully

After pregnancy, cows not only need to maintain their own nutrition, but also need to supply the nutritional needs of fetal growth and development, but also store certain nutrients to ensure lactation. Therefore, it is necessary to replenish 1m / m / m / 2kg concentrate daily. If you have the necessary conditions, you can feed the mixed concentrate, which is 30% of corn, 20% of bean cake, 15% of rice, 15% of cottonseed cake, 5% of rapeseed cake and 15% of rice bran, and some bone meal and salt should be added properly. do not feed moldy feed regularly, quantitatively and less. Drinking water should be clean, be careful not to drink empty belly water and ice water, it is best to feed warm hot water. On rainless days, we should insist on driving cattle up the mountain for grazing. Grazing can not only make cattle eat green fodder, but also increase the amount of exercise, which is beneficial to the health of cattle. Herding cattle should choose the bushes that are leeward and sunny, and do not let pregnant cattle feed on frost grass. The feed should be diversified, palatable and easy to digest. As the winter house feeding is generally based on coarse materials such as hay and rice straw, attention should be paid to the preparation of feed, and it is best to make ammoniated feed for cattle, which can not only improve palatability, but also increase nutrition. If there is a lack of protein feed during supplementary feeding, it can be fed with urea feed, which can supplement the deficiency of protein. The daily dosage of urea can be supplemented by 40 grams per 100 kg of cow body weight.

Prevent miscarriage and ensure the health of mothers and babies

Improper feeding and management of pregnant cows in winter is prone to abortion, which is characterized by vaginal mucus in the early stage of pregnancy, constantly looking back at the abdomen, restlessness, breast enlargement, waist arch, repeated micturition posture, obvious abdominal pain and stopping fetal movement. During the treatment, progesterone can be injected intramuscularly with 0,5 Murray 1g, once a day, for 6 days, and good results can be obtained.

Proper exercise and reasonable exertion

In the second trimester of pregnancy, pregnant cows should gradually reduce the intensity of causative labor, and it is strictly forbidden to draw cold whips, hurry for life, and turn sharp bends in the middle of pregnancy, and to slow them down. One month before delivery, the forced labor should be stopped so as not to cause miscarriage. when it is sunny and sunny, pregnant cows who are not in service should be led outside for proper exercise to strengthen their physique and prevent dystocia. Posterior pituitary hormone can be used to induce labor in mild dystocia. A hypodermic injection of 60 murmurs of 100 units, or diethylstilbestrol subcutaneous injection of 10 murmurs of 20 milligrams, can achieve good results.
