Breeding raising method for meat sheep

Abstract

The invention discloses a breeding raising method for meat sheep. The method is characterized by comprising the steps: by taking poll dorset sheep as a male parent and small tailed han sheep as a female parent, carrying out hybridization, wherein the propagative technologies mainly comprise estrus control, hormone treatment, biological stimulation, vaginal sponge method and prostatic hormone method to promote superovulation, a tit double-lamb agent or a twinborn-medicament, which is an aqueous agent and an oil agent, is adopted; 1 ml of the aqueous agent is subcutaneously injected into the neck of each of the male sheep once in 5 weeks and 2 weeks before mating; and 2 ml of the oil agent product is intramuscularly injected at the buttock in 2 weeks before mating. Twins and polyembryony are induced. Fundamental hybridization improvement is carried out from biological characteristics, artificial raising environment selection, raising variety selection, propagative technical improvement, raising feed research, fattening management technologies and disease diagnosis, prevention and treatment, and the meat sheep variety is bred, so that implementation of industrialization of the meet sheep is promoted.

Description

technical field [0001] The invention belongs to the field of breeding technology, and specifically relates to crossbreeding hornless Tauset sheep as the male parent and Small-tailed Han sheep as the female parent, and breeding a breed with a large number of reproduction, precocious, fast growth and development, and high meat production performance. fine-bred mutton sheep. Background technique [0002] Since my country does not have its own specialized mutton sheep breeds, it has been relying on the introduction of foreign mutton sheep breeds, but it is often heavy on introduction, light on breeding, heavy on purchase, and light on utilization. should work. There are more than 40 million sheep in Gansu. The task of breed improvement is huge, and the demand for meat-type breeding sheep is also huge. According to a preliminary estimate: if 30% of the existing sheep in Gansu will be improved for mutton production in recent years, at least 45,000-50,000 meat-use type rams will b...

Problems solved by technology

The third is to import and hybridize a variety that basically meets the requirements, but only has a major physiological defect that cannot be overcome by itself in a certain aspect, or it is used when it is difficult to improve certain qualities of the variety by purebred breeding.
