Problems solved by technology

[0005] At present, my country has not yet established and formed a mutton sheep breeding technology system and an industrialized development system. A series of problems such as the lack of high-quality mutton sheep varieties with independent intellectual property rights, low fecundity of existing meat varieties, and poor muscle quality have seriously restricted the rapid development of my country's mutton sheep industry. development bottleneck

Embodiment

[0021] (1) Hybrid innovation

[0022] A. Foreign Specialized Meat-using Sheep Breeds as Male Parents

[0023] According to the male parent selection standard, 10 purebred Dorper sheep were selected as the male parents of a new breed of meat sheep with high fecundity. Standards for male parent selection: consistent appearance, no horns, white coat, strong physique, long and wide body, barrel-shaped body, wide front chest, straight back and waist, well-opened ribs, plump buttocks, four limbs Strong, strong, and well-proportioned body; newborn weight 3.5kg, daily gain of 200g from 1 to 3 months, and 180g daily from 3 to 6 months; weaning weight of lambs at 3 months is 22kg; weight at 6 months is 38kg; adult rams Weight 70~80kg.

[0024] B. Local fine varieties as female parent

[0025] 160 Hu sheep lambs selected from the offspring of high-yielding ewes were used as female parents. 100 individuals with good body condition and single litter size ≥ 2 were selected.

Abstract

The invention discloses a breeding method of a new variety of a sheep with high fecundity. The breeding method can mainly solve the problem of insufficient quality character of the existing sheep meat of our country at present, and thereby the economic benefit of breeding the mutton sheep is obviously improved. The key point of the technical scheme is: a set of autonomous, high-efficient and perfect breeding method of the new variety of the sheep with high fecundity is set up from a complex hybridization technique by fully using two genetic resources at home and abroad and applying classic number of quantitative genetics and technologies.

Description

technical field [0001] The invention relates to the technical field of sheep breeding, in particular to a breeding method for a new breed of meat sheep with high fecundity. Background technique [0002] In recent years, due to the great changes in the demand relationship between domestic and foreign markets for wool and mutton, the sheep industry has gradually shifted from wool and wool to both meat and wool, and then to meat. my country's fastest growing animal husbandry industry. Since 1970, developed countries in the sheep breeding industry have gradually established and formed a relatively complete mutton sheep breeding system. On the basis of extensive application of economic hybridization, new breeds specialized in early-maturing meat and suitable for lamb production are bred, with a high lambing rate. Higher, good lactation performance, fast growth and development of lamb, good meat performance, high feed remuneration, etc. my country's mutton sheep breeding wo...
