Abstract

The present invention relates to a breeding method and application of a new breed of lambs with high reproductive ability. The breeding method comprises: mating male Dongfli sheep with female Small-tailed Han sheep to obtain F1 generation male sheep and F1 generation female sheep; Crossbreed the F1 generation male sheep with the female Hu sheep to obtain the F2 generation male sheep and the F2 generation female sheep; cross-cross the F2 generation male sheep and the F2 generation female sheep to obtain the F3 generation; establish in parallel according to the above method Families, the F3 generations of each family are cross-crossed with each other, and the traits are measured and selected, so as to obtain the new strain of high reproductive ability and multiple lambs. The new strain has high fecundity and can be used for matching hybridization or producing lamb meat, so as to meet the production mode of large-scale house feeding and the huge market demand.

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...
