Calf Spring Management Mo relax

Spring is the peak period of cattle mating, but climate change is unpredictable and the incidence and mortality of cattle are extremely high. Therefore, it is necessary to strengthen the feeding and management in the spring, scientifically fertilize the fetus, ensure the safety of the mother and child, and increase the reproduction rate. On March 6th, Xin Yaping, an associate professor of the Academy of Sports Sciences of the Northwest Agriculture and Forestry University, said in an interview with reporters that in the spring, many cattle farmers have loosened their management of the cattle, resulting in a lot of problems. I hope to pay attention to the following aspects.

The estrus cows were excited and excited after the estrus of the cows were in time. They continued to squeak and their tails were high. The white lucid translucent mucus came out of the vulva and could be drawn into 7-8 cm filaments by hand. The period of estrus in cattle lasts 18 hours, generally lasting 12-22 hours, and ovulation occurs 10-15 hours after the end of estrus. Therefore, the suitable mating time of the cow is: if the estrus occurs in the morning, it will be bred at 8-10 pm on the same day, and will be supplemented once at 7-8 am the next morning; if the estrus is in the afternoon, the breeding will be on the next morning and the afternoon or evening will be used once.

The empty cows are replenished every day with 50 grams of salt and 1-2 kilograms of barley, corn and soybeans. After drinking water first, feed the grass, wait until the cows have eaten until the five or six percents are full, feed the mixed concentrate, and then drink the salt water, and wait until the cows rest for 15-20 minutes before going out. After grazing, prepare enough water and night grass to allow the cow to freely drink and eat. When the cow is too fat, it can increase the amount of jousting, and feed more coarse material and juicy feed. If you are too thin, make up the fine material and green feed, and strive to achieve a medium sensation before breeding.

Careful feeding of pregnant cows Pregnant cows are required to meet the nutritional needs of their own and the fetus, so to provide high-quality compound feed, the formula is corn 30%, soybean cake 20%, rice 15%, cottonseed cake 15%, rapeseed cake 5%, rice bran 15%, proper amount of calcium hydrogen phosphate and salt. Feed 1-2 kilograms of concentrate each day, enough green feed and ammoniated feed. Timing, feeding less, drinking warm water. Sunny days choose to grazing where the leewards are sunny and enhance the body movement of the cattle.

Prevention of miscarriage and production of mother and child safe mid-pregnancy, cattle should gradually reduce the intensity of military service, is strictly prohibited to pull cold whip, dry emergency, turn sharp bend, so that heavy duty. One month before childbirth should be stopped to prevent miscarriage. If the cow is pregnant, vaginal mucus outflows, constantly looks back at the abdomen, and it is unsettled; late breast enlargement, oscillating urinary frequency posture, abdominal pain is obvious, fetal movement stop is abortion omen, to prompt treatment, progesterone can be used 0.5-1 grams Intramuscular injection, once daily, for 4-6 days. Due to the lack of exercise, the cow can produce subcutaneous injection of oxytocin at 60-100 units with better dystocia.
