Abstract

The invention relates to a method for cultivating breeding sheep of sheep for wool. The method comprises the steps of selection of the breeding sheep and feeding of the breeding sheep, wherein the selection of the breeding sheep comprises the steps: S1, eliminating newborn lambs which do not meet a standard of birth weight; S2, eliminating 10%, which have a thin cannon circumference, of the newborn lambs; S3, eliminating 20%, which have a small abdomen skin area, of the newborn lambs; S4, eliminating newborn lambs which cannot meet a standard of wool fineness; and S5, establishing a flock of the breeding sheep; and the feeding of the breeding sheep comprises the steps: X1, feeding the breeding sheep with sufficient colostrum, and drenching the fed breeding sheep with 10 mL of sheep rumen liquor of adult healthy sheep; X2, performing supplementation of lactation by ewes; X3, feeding the lambs at the age of 1-7 days with a feed; X4, when the lambs grow to an age of 7-28 days, isolating the lambs from the lactating ewe 4 times a day, and feeding the isolated lambs with the feed for 2 hours during each isolation; X5, when the lambs grow to an age of 28-60 days, isolating the lambs fromthe lactating ewe 3 times a day, and feeding the isolated lambs with the feed for 1 hour during each isolation; and X6, performing one-time compelled weaning on the lambs. Through the selection and feeding of the newborn lambs, the breeding sheep with finer high-yield wool are cultivated.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a method for breeding sheep for fluffy sheep. Background technique [0002] Excellent breeding sheep play a decisive role in the improvement of wool sheep breeds, the selection and breeding of original breeds and the cultivation of new breeds. Therefore, breeding and providing high-quality breeding sheep that meet the standards and giving full play to the role of high-quality breeding sheep are important means to promote the overall development of the wool sheep industry and improve economic benefits. Generally, after birth weight, weaning, six-month-old and one-year-old weight and body size are considered and phased out, the basic breeding sheep are finally determined for breeding. There are also individual core breeding sheep farms that undergo molecular screening at the lamb stage, and the eliminated part is not suitable. The lambs used for breeding are re...
