Abstract

The present invention relates to a breeding method a new multi-lamb strain with high reproductive ability and an application of the breeding method. The breeding method comprises the following steps:mating male east Friesian sheep with female small tailed Han sheep to obtain a F1 generation male sheep and a F1 generation female sheep; crossbreeding the F1 generation male sheep and female Hu sheepto obtain a F2 generation male sheep and a F2 generation female sheep; crossing the F2 generation male sheep and the F2 generation female sheep to obtain a F3 generation; and parallel-establishing families according to the above method, crossing the F3 generations of each family, and performing character determination and breed selection to obtain the new multi-lamb strain with high reproductiveability. The new strain has high reproductive ability and can be used for supporting crossbreeding or producing lamb meat, so as to meet a production mode of large-scale house feeding and huge marketdemands.

Description

technical field [0001] The invention belongs to the field of multi-lamb breeding, and in particular relates to a breeding method and application of a new strain of multi-lamb with high reproductive ability. Background technique [0002] Fecundity is the ability of a single breeding sheep to reproduce offspring, and it is an important link in the sheep breeding industry. Only by improving the fecundity of the flock can the number and quality of the flock be increased, and better economic benefits can be obtained. There are certain differences in the fecundity of different breeds of sheep. Rural sheep are generally raised on a household basis, and the flocks are mostly large and small, and male and female are mixed. Long-term wild interbreeding and inbreeding cause breed degeneration, low fecundity of breeding sheep, slow proliferation of flocks, and low economic benefits. Improving the reproductive rate of ewes is the key to gaining profits for farms. Integrating market de...
