A kind of breeding method of snowflake mutton sheep

Abstract

The invention discloses a method for breeding snowflake mutton sheep, taking a Hu-sheep as thefemale parent and a black head DuBo-sheep as the male parent , and get a first generation of HeiDuHu flock after hybridization,choose a generation of rams and ewes phenotype and pattern distribution, specific standards: black and white flowers all over the body with piece flowers distributed evenly and black and white flowers head;taking a Small Tailed Han sheep as the female parent and a black DuBo-sheep as the male parent ,and get a first generation HeiDuHan flock after hybridization, choose a generation of rams and ewes phenotype and pattern distribution, specific standards: Blossom-headed, parts of body are distributed in black, overall area of black is not less than 50%;making the first generation of HeiDuHu rams or ewes copulated with the first generation of HeiDuHan ewes or rams togive birth to a second generation of HeiDu Han sheep, choose the lambs with black and white flowers distributed evenly for breeding, and get the snow mutton sheep.The mutton from the snowflake mutton sheep bredis fragrant, fresh and tender, the mutton fat is deposited between muscle fibers, which contains the amino acids required by the human body and has a low cholesterol with per 100 grams of the mutton is less than 5-9 grams of the conventional mutton.

Description

technical field [0001] The invention belongs to the field of animal breeding, and in particular relates to a method for breeding snowflake mutton sheep. Background technique [0002] Mutton is a meat food with excellent nutritional characteristics. Its meat is tender and delicious. It is a nutritious food with high protein, low fat and low cholesterol. health benefits. From the perspective of mutton nutritional components, according to the determination of the Institute of Nutrition and Food Hygiene, Chinese Academy of Preventive Medicine, mutton has excellent characteristics compared with other common meats. The contents of protein, fat and cholesterol in every 100 grams of edible lean mutton are respectively 20.5 grams, 3.9 grams and 62 milligrams, the protein content is higher than other common meat protein content, while the fat and cholesterol content is relatively low in common meat such as pork, beef and poultry. The contents of lysine, arginine, histidine, threonin...

Problems solved by technology

Only a few of the introduced new varieties are bred and purified in enterprises and scientific research units, while most of them flow directly into the market, and the quality and hybridization effect of the varieties cannot be monitored

Due to my country's vast territory, great climate differences, different ecological conditions, and different natural resources, at present, there is no hybridization utilization system suitable for different regional characteristics, and the lack of a unified planning breeding system has led to the fact that most of the mutton in my country is some local breeds and hybrids. Mutton, there is almost no mutton of specialized mutton sheep breeds, which leads to low production level, low meat yield and poor quality of mutton sheep

In recent years, the price of mutton in my country has continued to rise, and the contradiction between supply and demand has continued to increase. On the one hand, due to the reduction in the number of breeding, and on the other hand, because the hybrid advantage is far inferior to the breed advantage, it is difficult to improve the production level of mutton by hybridization and local breeds, which has led to The mutton market is chaotic, and fake mutton is flooding the market, making it impossible to form a market system for high-quality, high-priced, and graded sales of mutton
