First, abortion reasons 1. Disease causes. When the goat is infected with chlamydial disease during pregnancy, chlamydia grows and reproduces in the placenta, especially the hairy leaves, causing inflammation of the affected area, which results in early fetal output. After being infected with chlamydial disease, this type of ram can be transmitted to the ewes through breeding opportunities. Most of the affected sheep suffered a miscarriage about 1 month before birth. Before the miscarriage, only abnormal expressions, abdominal pain, and stillbirth were discharged during abortion. An effective method of prevention is to administer the vaccine to the sheep each year. Brucellosis often occurs when the ewes are 3-4 months pregnant. The first time the sheep is born, the abortion rate is very high. Regular vaccination of sheep can prevent this disease. 2. Nutrition deficiency. In the winter and spring withered grasses, the type of feed is single, and the nutrition is lacking. At this time, when the ewes are in the gestation period, the demand for nutrients increases continuously, the body does not make ends meet, and fetal dysplasia leads to miscarriage. 3. Improper management. Such as sudden changes in climate, drinking water, drowning water, feeding mildew, foraging, can be caused by pregnant women abortion. Second, comprehensive prevention measures Strengthen feeding and management, do a good supplement in winter and spring seasons, and feed pregnant sheep more carrots and grass meal to increase its resistance to disease; promote plastic greenhouses to raise sheep, ban on feeding mildew forage feed; Cleanliness, timely cleaning of manure, concentrated fermentation treatment, regular disinfection, early injection of anti-abortive vaccine; isolation of the aborted sheep, regular disinfection of the site, pasture, feeding trough, etc.; try to use artificial insemination technology to ewe mating To prevent infection.
