A kind of hybrid breeding method of Nongben sheep

Abstract

The invention relates to a hybrid breeding method of Nongben sheep, which belongs to the field of breeding methods for new strains of animals. The breeding method uses Hu sheep as the female parent and Dorper sheep as the male parent to carry out crossbreeding to produce F1 generation flocks; use F1 generation ewes and Hu sheep Hybridization of sheep and rams, F1 generation rams and Hu sheep ewes are crossed to produce F2 generation sheep flocks, self-breeding of F2 generation sheep flocks, sub-breeding, and finally a new strain of Nongben sheep; the cultivated Nongben sheep This new breed of sheep maintains the basic shape and appearance characteristics of Hu sheep. It has a large body, full muscles in the forequarters and hindquarters, fast growth and development, and high meat production rate. The adult weight of rams is over 90 kg, and ewes are 60 kg. Above, the reproduction rate is over 220%, with strong adaptability, suitable for barn feeding and development of fat lamb production.

Description

technical field

[0001] The invention relates to a method for cultivating new strains of animals, in particular to a method for cultivating nongben sheep by hybridization. Background technique

[0002] China has a long history of raising sheep and is a big sheep raising country in the world. In recent years, in our country, with the improvement of people's living standards, the change of people's food structure and the higher and higher requirements for healthy food, people consume more and more mutton, thus promoting the rapid development of the mutton sheep industry. develop. Raising sheep to get rich has also become a hot spot in the animal husbandry industry today. But at the same time, when the traditional sheep raising industry is rapidly transforming into the modern sheep raising industry, the problem of low productivity of sheep breed resources has become an important bottleneck restricting the development of the modern sheep raising industry. The region has introd...
