Raising sheep to prevent inbreeding
In rural areas, there is a widespread problem of not arranging male rams for many years, and mating is very serious. There are shortcomings of the "two drops and one high" in the mating of sheep. Namely: sheep breeding performance decline, variety degradation, stunting, growth retardation, meat production, hair production decreased by 50%; reproduction rate decreased, freak, abortion, chemical, stillbirths continue to appear; sheep disease resistance is poor, The mortality rate is high. These problems must cause the sheep farmers to attach great importance to take measures to seriously solve them. First, timely exchange of species of rams. After two years of continuous use, the rams of a flock are exchanged with the same species of rams in other flock to avoid inbreeding. Second, the species of rams should be raised separately. In the mating season, rams with distant ties are used for breeding. Third, establish an artificial insemination station in rural areas with a large number of sheep. The insemination station should establish a file system, including a sheep breeding registration form, a lamb registration form, and an offspring determination record form. With these records, the kinship is clear, and it is possible to have a plan to select and match and avoid inbreeding.
