Method for efficient reproduction of yaks and production of dzos

Abstract

The invention discloses a method for efficient reproduction of yaks and production of dzos. Through group management, nutrition control, oestrus identification and artificial insemination, the femaleyaks can resume the oestrus cycle in an oestrus season to achieve oestrus, mating and conception, a feed supplement standard and an efficient reproduction mode are planned for the female yaks different in reproductive conditions, the estrus rate of the yaks and the dzo conception effect are improved, the production of the dzos is accelerated, the technical and industrial development of efficient breeding of dzos is promoted, thus the problems are solved that the yaks in china are low germplasm performance and the breeding efficiency is low, and the healthy and green development of ecological breeding of the yaks and the dzos in the vast pastoral areas of the Tibet plateau is facilitated.

Description

technical field [0001] The invention belongs to the technical field of cattle breeding, and in particular relates to a method for efficient breeding and production of yaks. Background technique [0002] In recent years, the crossbreeding and improvement of yaks with small dairy cattle breeds Jersey and Angus beef cattle with smaller heads have achieved remarkable results, and the dystocia rate of the first generation of hybrid P cattle has been significantly reduced, and the survival rate of calves has increased. With different degrees of improvement, the adaptability and production performance of the offspring have good performance. [0003] There are a large number of native yellow cattle and the hybrid offspring of Simmental, Holstein and cattle in the agricultural areas and semi-agricultural and semi-pastoral areas of Qinghai Province. Over the years, there are mainly two production technology schemes for Pian cattle, one is to use local cattle Wait for the hybrid offsp...

AI Technical Summary

Problems solved by technology

[0004] However, due to the large size of the imported Simmental and Holstein cows in the traditional production method of P cattle, it is easy to cause dystocia in the process of using yak as the female parent to produce P cattle. The Qinghai-Tibet Plateau is limited by its unique natural environment and geographic location. The nutritional condition is poor, and the natural estrus rate of yaks is low. In the process of artificial insemination and production of cattle, the number of mating yaks is small. The production cost of this work is high and the effect is not good. Obviously, there are great difficulties in the production and promotion of Pian cattle, which is not suitable for the implementation of large-scale technology demonstration and promotion. In recent years, due to the continuous rise in the price of beef cattle, local cattle are used as female parents to introduce Angus beef cattle or Simmental beef cattle. Natural mating or artificial insemination improvement, the economic benefits of hybrid offspring are significant, however, using local yellow cattle or hybrid cattle as the female parent to produce P cattle production costs are too large, and the economic benefits are mediocre
