Winter pregnant cows prevent abortion measures

Pregnant cows raised in winter cattle farms are prone to miscarriage, and the reasons are many. In winter, the weather changes greatly, and it is faced with the threat of grass, frost, lack of green feed and cold, especially for the pregnant cows that will be allocated later in the spring. As the late fetal development is accelerated, such as poor feeding and management, feeding can not keep up, can easily lead to abortion and disease, resulting in irreparable damage. Therefore, we must fully grasp the pregnancy management of pregnant cows, pay attention to the prevention of pregnant cattle abortion, to ensure that pregnant cattle safe winter.

Prevention of Frost Damage to Pregnant Cows

The autumn cows have the dual effect of saving feed and beef, but they can't grazing in the morning after the frost to prevent the frost from harming the pregnant cows. Because in the morning the cows are hungry, their stomachs are empty, they are bulimia, they often bulge due to overeating and may even swell. Pregnant cows are more prone to fetal movement, restlessness or miscarriage. Grazing cattle in autumn Note: In the morning after the sun comes out, graze without dew; don't feed frosted or frozen fodder to pregnant cattle that are being fed.

Pay attention to keeping the house warm

Winter raising pregnant cows should do a good job in keeping the house warm, so as to reduce the heat loss of the cow body and ensure that the pregnant cow can safely live for the winter. The optimum temperature for cattle is 8°C~15°C, which is beneficial for preventing bodily miscarriage and miscarriage. Its effective approach is: close the doors and windows of the cowshed, plug loopholes to prevent the intrusion of thieves; the ground should be dry, not on the cold, to prevent the cold and wet; to do the wall is not windy, not to freeze, the shed does not hang frost, so pregnant cows have a A good wintering environment.

Meet the nutritional needs of pregnant cows

To ensure maternal winter, we must grasp the post-mortem condition of pregnant cows. In addition to the nutrition needed to maintain the life activities of pregnant cows, and to meet the nutritional requirements required for the rapid growth and development of the fetus, it is necessary to feed compound feeds with multiple varieties and nutrition. . In order to ensure the stability of the nutritional balance of pregnant cows, it is not possible to suddenly change the feed, to do regular ration, first coarse after the fine feeding method, in order to improve burdock, defense cold, reduce body temperature loss to provide protection, in order to guarantee the birth of yak Large, strong, strong disease resistance.

Feed loose and delicious feed

When the pregnant cow approaches the late pregnancy, the fetus grows rapidly, the uterus expands and the squeezing force of various organs increases, thereby affecting the growth of the cow and the fetus. This requires that pregnant cattle be fed with some bran-like loose feed, and at the same time reduce the amount of crude hard feed to protect the normal growth and development of the fetus, reduce the pressure on the organs, ensure smooth blood circulation, and prevent miscarriage. For maternity cows in the period of labor, care should be taken to feed small, good quality, easily digestible and delicious feeds.

Give pregnant cows plenty of water

Water is the first need in all life activities. In winter, most of the cattle to eat hay dry material-based, if the water shortage will cause reduction in saliva, digestion weakened, the cow rumen motility slows down, even the food plot, resulting in valve stomach blockage. Therefore, to give cattle a lot of water, but to drink cold water to the cattle will make the cow uterus contraction, may lead to miscarriage. Therefore, it is necessary to warm the pregnant cows in winter to reduce heat loss and avoid unnecessary losses.

Pregnant cows insist on proper exercise

Cows consume too much nutrients after pregnancy and are prone to frailty and decreased resistance. Therefore, we must grasp the feeding and management of pregnant cattle during pregnancy, and adhere to regular and appropriate exercise. Due to the cold weather in winter, we must prevent swift walking and jumping. In the later stages of pregnancy, do not climb mountains, steep slopes and dangerous roads, and do not use ice slides to prevent slipping. Pregnant cows should be kept separately from other livestock and managed separately to prevent biting, top racking and squeezing to ensure the safety of pregnant cows and avoid miscarriage.

Prevention of occurrence of bovine fetal movement and pain

Late pregnancy, due to the uterus content is too large, excessive expansion, coupled with the poor quality of the body, strong sensitivity, easy to cause fetal movement abdominal pain, manifested as often unrest, screaming, yelling, vaginal bleeding, cattle back Looking at the abdomen, frequently doing urination posture, palpation of fetal activity enhancement. Effective practice is: to maintain adequate rest and quiet pregnant cows, while the use of drugs for symptomatic treatment, available Analgin injection 30 ml ~ 40 ml intramuscular or intravenous injection, or potassium bromide 20 g ~ 40 g orally, with To calm the fetus; can also be used progesterone 1 g ~ 2 g intramuscular injection, 1 time / day, once every 3 days, can receive a good effect of abortion.
