Abstract

The present invention relates to the technical field of crop breeding and particularly to a method for improving Guizhou buffalo hybridization. The technical scheme is as follows: Murrah buffalos areused as male parents to cross with Guizhou buffalos to select first hybrid cows (F1 generation), then the first hybrid cows cross with the Guizhou buffalos to produce second hybrids (F2 generation), and well developed cows and bulls are selected from the F2 generation to be crossed and fixed. Finally, the obtained improved Guizhou buffalo hybrid breed maintains characteristics of excellent Guizhoubuffalo breeds, a growth performance is improved, a beef grade is improved, and the improved Guizhou buffalo hybrid breed can be mass-produced and is a commercial buffalo with good quality and economic benefits.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a Guizhou buffalo hybrid improvement method.
