Autumn is the peak period of cattle breeding. In the severe winter season when the grass is withered, pregnant cows need not only cold attacks, but also all the nutrients needed for the growth and development of the fetus. In adverse climate conditions, if pregnant cattle are improperly reared, especially if they experience abrupt changes in temperature, they may easily lead to a decline in the constitution of pregnant cows during hunger and cold stress, and even result in the death of the mother. For this reason, the following measures should be taken for pregnant cows.
1, renovation bar, cold warm
Pregnant cows should have a separate barn to avoid crowding and kicking to cause miscarriage. The barns should plug the loopholes, shelter from the wind, do not leak rain, and do not wet. The bedding is often replaced. On a sunny noon, the cows are allowed to go outside and enjoy the sun.
2, strengthen nutrition, carefully reared
After the cow is pregnant, in addition to maintaining the nutrients it needs, it also needs to provide nutrients for the growth of the fetus, while also accumulating certain nutrients to ensure the production of lactation. Therefore, 1-2 kilograms of concentrate should be fed daily. Conditional feeding of mixed concentrates is possible. The proportions are: corn 30%, soybean cake 20%, rice 15%, cottonseed cake 15%, rapeseed cake 5%, rice bran 15%, and some bone meal and salt are also added properly. Do regular, quantitative, and less to add ground, do not feed mildew feed. Drinking water should be clean, be careful not to drink empty belly water and ice residue water, it is best to feed warm and hot water. In the absence of rain, it is necessary to insist on cattle grazing up the mountain. Grazing can not only allow cattle to eat green feed, but also increase the amount of exercise, which is beneficial to the health of cattle. Put cattle in the leeward sunny bushes, do not let the pregnant cows eat frost grass. Feed should be diversified, palatable, and digestible. Since winter feeding is generally dominated by coarse materials such as hay and rice straw, attention should be paid to the modulation of feed. It is best to produce ammoniated feed for cattle. This will not only increase palatability, but also increase nutrition. If there is a lack of protein feed during supplemental feeding, urea feed may be used, which can supplement the deficiency of protein. Daily dosage of urea may be 40 g per 100 kg of body weight.
3. Prevent miscarriage and ensure the health of the mother
Winter pregnancy cows improper management and prone to miscarriage, the symptoms of vaginal outflow of mucus during the pre-pregnancy, continue to look back at the abdomen, upset unrest; late pregnancy showed breast enlargement, arch waist, repeated urination posture, abdominal pain, fetal movement stopped. Progesterone intramuscular injection 0.5-1g can be used for treatment, once a day, once every 4-6 days, can receive good results.
4, proper exercise, reasonable service
In the middle of pregnancy, pregnant cows should gradually reduce the intensity of military service. In the military service, it is strictly forbidden to draw cold whip, to rush, to switch to sharp bends, to slow down the service, to stop working until 1 month before labor, so as to avoid causing miscarriage, and not to feed completely. When pregnant cows are in sunny weather, they should be drawn to the outside for proper exercise to enhance their physical fitness and prevent dystocia. Mild dystocia can be induced by the use of posterior pituitary hormones, with a subcutaneous injection of 60-100 units.
