Beef cattle cross improvement and production method

Abstract

The invention discloses a beef cattle cross improvement and production method comprising two stages. The first stage is the angusation of basal cows: anguses are taken as male parents, the current basis cows are crossed, and the generation of the basis cows are called the first angus cross generation; all the bulls of the first angus cross generation are put on the market, and healthy and sturdy female calves are reserved; the hybridization institution of the first angus cross generation is that the anguses are taken as the male parents, the generation of the first angus cross generation is called as the second angus cross generation, all the bulls of the second angus cross generation are sold, and the female caves of the second angus cross generation are identified and reserved; and another hybridization institution of the first angus cross generation is that the limousines are taken as the male parents, the generation of the angus is called as lyan red bulls, all the male calves of the lyan red bulls are sold, and the female calves of the lyan red bulls are reserved. The second stage is the rotational cross between the anguses and the limousines: The second angus cross generation is copulated with limousine bulls, and the generation is called the lyan red bulls; the lyan red bulls are copulated with the angus bulls, and the generation is call as angus cross red bulls; and the cross continuously cycles in this way. The method is simply in implement and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of animal breeding and hybridization, and relates to a beef cattle hybridization improvement and production method, more specifically, to the breeding of female parent groups in beef cattle production, the utilization of hybridization advantages, commercial beef cattle production models, and beef cattle hybridization production selection. application of the matching system. Background technique [0002] my country's beef cattle industry started relatively late, and it only took a short time to become an industry, only more than 30 years, but the development speed is relatively fast. Over the past 30 years, my country's beef production has increased more than 30 times, making it the third largest beef producer in the world. my country started cattle improvement and breed selection in the 1960s. Over the past 50 years, we have cultivated dual-purpose breeds such as grassland red cattle, Sanhe cattle, Horqin c...
