Methods to avoid inbreeding in raising sheep

Many breeders often have the phenomenon of inbreeding when raising sheep, so the lambs often grow slowly, weak and sick, and the survival rate is often low, resulting in the decline of the reproductive performance of the whole flock, resulting in huge losses. So is there any way to stop their inbreeding? the following pro-farm network brings you ways to raise sheep to avoid inbreeding.

In order to reduce the breeding cost, many farmers do not change the breeding sheep for a long time, resulting in that the whole flock is all close relatives, and the sheep born later are all problematic lambs. Generally speaking, a breeder sheep needs to be replaced after one or two years of use, so as to alienate the blood relationship of the whole flock. The new breeder sheep had better not be of the same race as the previous breed sheep, and had better cross-breed, so as to make the whole flock better and better.

2. Male and female separate cultivation

Many people raise sheep centrally, and rams and ewes are all raised together, so that when ewes are in estrus, they mate on their own. In this case, farmers do not know which breed is mating, which is easy to cause confusion. Therefore, rams and ewes had better be kept separately in captivity, and when ewes are in estrus, choose rams to give artificial assistance, make good records, and avoid inbreeding as far as possible.

3. Establish artificial insemination base.

In large-scale farms or rural areas with a large number of sheep, set up an artificial insemination base, collect the test data of breeder sheep and lambs, and collect their records into files, so that the blood relationship of all sheep is very clear. each breeding only need to extract files, planned selection to avoid inbreeding.
