Problems solved by technology

At present, the production of Tibetan sheep in our province is still in the stage of small-scale grazing and breeding. Due to the harsh natural environment and the limitations of existing breeding management technology, the benefit of Tibetan sheep breeding is not high, and the ecological problems such as overloading and overgrazing caused by it are becoming more and more prominent. , has become a bottleneck affecting the development of the Tibetan sheep industry in our province

Abstract

The invention belongs to the technical field of animal reproduction methods, and particularly relates to a method for increasing the reproduction rate of Tibetan sheep. The method includes the steps of forming an ewes group and a ram group; performing sex hormone injection before first mating, and completing one reproduction cycle in a gestation period of 5 months, a lactation period of 2 months and a to-be-mated period of 1 month after mating, wherein three reproduction cycles are completed in two years; performing nutrition regulation for ewes and rams in the warm season and the cold season.According to the method, under the grazing condition, by improving the feeding management technology and performing reproduction regulation, the seasonal estrus characteristic of Tibetan sheep can bebroken through, the ewes can rut in time for mating after the weaning of two-month-old lambs, and three reproduction cycles in two years are realized.

Description

technical field [0001] The invention belongs to the technical field of animal breeding methods, in particular to a method for improving the reproductive rate of Tibetan sheep. Background technique [0002] Tibetan sheep is the main dominant livestock breed on the Qinghai-Tibet Plateau, and has strong adaptability to the harsh natural environment of high cold and hypoxia, which is inferior to other sheep breeds. Qinghai Province has a wide distribution area of ​​Tibetan sheep, with as many as 11 million sheep. As one of the five major pastoral areas in the country, comprehensive factors such as the wide distribution of sheep in our province, the limitation of breed selection, and the importance of the ecological environment determine the province's sheep breeding. The sheep industry is a development model based on Tibetan sheep. At present, the production of Tibetan sheep in our province is still in the stage of small-scale grazing and breeding. Due to the harsh natural envi...
