Usually rams can match their offspring, but inbreeding has advantages and disadvantages, which easily leads to sheep stiffness and gene mutation, so inbreeding is generally not recommended. In order to prevent inbreeding, artificial insemination stations should be set up in some sheep farms with large breeding scale and large number to record the breeding records of all breeding sheep, which can not only improve the breeding efficiency, but also avoid inbreeding, and can also replace rams regularly.
1. Can a ram match his offspring?
1. Can a ram mate with a female offspring?
Generally, rams can mate with their offspring, but this mating method has advantages and disadvantages, which easily leads to sheep stiffness and gene mutation, so inbreeding is usually not recommended.
2. How to prevent sheep from inbreeding?
(1) Replace the ram in time.
In the process of feeding, the ram should be replaced regularly. Usually, a ram needs to be replaced after two years of continuous feeding, which can not only improve the reproductive ability of sheep, but also effectively prevent the inbreeding phenomenon of sheep.
(2) feeding alone
(1) Feed ewes in groups. When the ewe is not in estrus, the ram is put into the sheephouse alone, and after the ewe is in estrus, it is paired with the ram to artificially assist mating, so as to improve the mating success rate.
② Attention: Pay attention to the blood relationship when choosing rams, and be sure to choose ewes that are far away from ewes for breeding.
(3) Artificial insemination
For large-scale sheep farms, artificial insemination should be adopted, artificial insemination stations should be established, and all data such as breeding records and lambs should be recorded, so as to effectively choose mating and avoid inbreeding.
Second, what are the consequences of sheep inbreeding?
1, disadvantages of inbreeding
(1) Sheep inbreeding will lead to the decline of reproductive performance, variety degradation, growth retardation, poor disease resistance and high mortality.
(2) The meat yield and wool yield of sheep decreased by 50%, the reproductive rate decreased, and malformations, miscarriages, stillbirths and stillbirths appeared constantly.
2. Advantages of close relatives
(1) Early exposure of harmful recessive genes
In Russia and Japan, most harmful genes in sheep are recessive, and in most cases, harmful genes will be covered by beneficial genes. Inbreeding can expose harmful genes in advance, eliminate inferior sheep in time and improve the genetic quality of sheep as a whole.
(2) Keep good blood.
For some excellent breeds, some farmers will choose inbreeding in order to maintain the excellent bloodline of sheep.
