Pay attention to observing the symptoms of labour. Cows are swollen about half an hour ago. The vulva is swollen. The sides of the tail are sunken and the breasts are enlarged. Clear mucous flows from the vulva 1 to 2 days before delivery. Pain occurs in the immediate vicinity of the delivery. Urine, uneasy.
Attention to timely midwife hybrids such as Charolais and other large-scale beef cattle are born with a large body size and a certain degree of dystocia. Midwifery must be performed to ensure that the mother and child are safe. When the cow has symptoms of labor, the cow is left lying and the hindquarters are disinfected. It is the two forelegs that come out with the head first. If burdock is not produced in time, check whether the fetal position and posture are normal. When the fetal forelimb and head have exposed the vulva, and the amniotic membrane is not ruptured, the amniotic membrane can be torn and the mucus in the oral cavity and nasal cavity of the fetus can be wiped off to prevent peri-inflation. When the fetus head passes through the vulva, one person should press the labia by hand to prevent the vulva from breaking.
Pay attention to postpartum management cows discharge the tires and clothes after about 12 hours of postpartum. If fetal clothing is not discharged 24 hours after delivery, surgical dissection should be performed. Postpartum cows should be given warm water, feed some nutritious and digestible feed to restore the cow's physical strength. At the same time, attention should be paid to the hygiene of livestock houses to prevent infectious diseases.
