How to prevent inbreeding in sheep? Farmers can do this

Mutton is now a major meat product in China, with a very wide consumer base across the country. As a result, more and more people are raising sheep, but many of them manage breeding in a rather extensive and careless way. This has led to inbreeding problems on many sheep farms, causing an overall decline in flock quality. So what are the harms of inbreeding in sheep? How can inbreeding in sheep be prevented? Let's take a look below.

1. The harms of inbreeding

Inbreeding in sheep causes very serious harm. The reproductive capacity of ewes declines noticeably, and breed quality degrades markedly. Growth rate drops, and meat and wool yields are naturally affected very severely. Most importantly, deformed fetuses, miscarriages and stillbirths and various other very serious phenomena occur. And even if lambs are born normally, their resistance is very weak and the survival rate is extremely low. Therefore, for this phenomenon, in order to ensure breeding profitability, we must be sure to prevent inbreeding among sheep.

2. How to prevent it

Replace rams at the right time

In the course of raising sheep, we usually need to replace rams after a certain period. Under normal circumstances, a breeding ram needs to be replaced after being kept continuously for about 2 years. It does not need to be culled; generally it is enough to swap it with the breeding ram of another flock. This can improve the reproductive capacity of the flock and effectively prevent inbreeding in sheep. For rams that have had production-related problems, they need to be culled promptly and new rams introduced, so that breeding profitability can be effectively expanded.

Raise them separately

When raising sheep, grouping and separate rearing is also very important. In particular, rams and ewes should be raised separately and individually. When the ewes are not yet in heat, the breeding rams should be kept alone in a separate sheep shed. Then, when the ewes come into heat, both rams and ewes can be led out of the shed, and manual assistance can be used to promote mating and increase the success rate of breeding. In addition, when selecting breeding rams, we must also pay attention to their blood relationships, and be sure to choose ewes that are distantly related by blood to the breeding rams for mating.

Artificial insemination station

Artificial insemination stations mainly depend on the scale of the operation, and are generally not suitable for small flocks. They are used more in sheep farms with large numbers and large scale. Because the number of animals is large, it is hard to remember them all clearly. So we should set up an artificial insemination station, based mainly on a record-keeping system, and clearly record all data such as the breeding records of all breeding sheep and the lambs. With a clear record table, blood relationships will be obvious at a glance. Therefore we can also effectively carry out selective breeding and mating, and avoid inbreeding.

The above is a brief introduction to the harms of inbreeding in sheep and how to prevent it. When raising sheep, preventing inbreeding is very important, so everyone must pay close attention to it. That is all for today's introduction. This article is for reference only, and we hope it can help you!
