The prolific performance of the selected parental ewes has obvious heritability. In breeding and raising, attention should be paid to the selection of twin rams as breeding rams, and the choice of leaving twin ewes as basic ewes.
Pre-breeding pre-feeding 1-1.5 months before the ewes supplementary feeding compound feed, short-term excellent feeding on poor ewes to restore body condition and promote estrus. During the breeding period, the weight of the rams should pay attention to increase the supply of protein, vitamin A, vitamin E and minerals, and feed a shelled egg every day to ensure its strong sexual desire and mating ability.
With multi-product breeder crossbreeding and multi-product breeder crossbreeding, the lambing rate of the hybrid generation can be significantly improved.
One effective breeding method is repeated breeding. During one estrus period, repeat the breeding with the same ram 6-8 hours apart; the second is frequent breeding. Some breeds, such as Small Tail Han sheep, can be estrus throughout the year. When the ewes are in estrus about a month after they are born, the ewes with good constitution will have better breeding and fertility rates.
Timely Replacing and Renewal In the sheep breeding process, attention should be paid to increasing the proportion of ewes in the sheep of the appropriate age, and timely elimination of old age, infertility, habitual abortion, poor maternity, poor milking, production of lambs, reproductive organs, and defective breasts. ewe.
