First, the cause of abortion
(a) chlamydia disease. When the ewes are infected with chlamydial disease during pregnancy, chlamydia grows and reproduces in the placenta coat, especially the hairy leaves, causing inflammation in the affected area, leading to early fetal output. After being infected with chlamydial disease, this type of ram can be transmitted to the ewes through breeding opportunities. The sick ewes suffered a miscarriage in the first month or so of prenatal birth. Before the miscarriage, only abnormal expressions, abdominal pain, and stillbirth were discharged during miscarriage. An effective preventative measure is to inject sheep with the relevant vaccine each year.
(b) Brucellosis. The disease often occurs when the ewes are 3 to 4 months pregnant and the abortion rate is high when the sheep first occurs. Regular vaccination of goats can prevent this disease.
(c) Nutrition deficiency. Winter and spring subtilis feeds are of a single species and lack of nutrition. At this time, when ewes are in the gestation period, the demand for nutrients continues to increase, and the body's inability to make ends meet, and the fetus is stunted, resulting in miscarriage.
(d) improper management. Such as the sudden change of climate, drinking ice dregs, feeding mildew, and being caught in and out of the circle can cause pregnancy abortion.
Second, comprehensive prevention and control measures
Strengthen feeding and management, do a good feeding in winter and spring seasons, and feed ewes with more carrots and grass meal to increase their resistance to disease; promote plastics in greenhouses to keep sheep and feed mildew forage; To clean, excrement timely cleaning, concentrated fermentation processing, often disinfection, in advance of the mother sheep injection anti-abortion vaccine, for the abortion sheep should be immediately isolated treatment, site, pasture, trough appliances and other thorough disinfection; try to use artificial insemination technology Mating ewes to prevent infection.
