Investigation,analysis,and recommendations on the hybrid improvement effect of Guanling Yellow cattle
摘要
Abstract
Samples were collected and statistically analyzed from four major townships with Guanling Yellow cattle farming in Guanling County,Guizhou Province.Comparative analyses were performed on five indicators:Introduced hybrid breeds,baseline body weight of dams,calf birth weight,deviation between actual calving date and expected due date,and calving performance.Hybridization patterns were summarized to provide references for the systematic construction of crossbreeding improvement systems for Guanling Yellow cattle,and to establish practical quantitative reference indices for selecting and retaining individuals after crossbreeding improvement of Guanling Yellow cattle.The results showed that for the first cross,Guanling Yellow cattle were used as dams mated with Simmental cattle sires.Using local Guanling Yellow cattle as dams makes full use of indigenous cow resources.Calf heifers retained as breeding females should have a birth weight above 31.00 kg.For the second cross,F₁ female progeny derived from the first cross were mated with Simmental cattle sires;calf heifers retained as breeding females should have a birth weight above 32.00 kg.For the third cross,F₂ female progeny derived from the second cross were mated with Simmental cattle sires;calf heifers retained as breeding females should have a birth weight above 35.00 kg.For the fourth cross,F ₃ female progeny derived from the third cross were mated with Limousin cattle sires;calf heifers retained as breeding females should have a birth weight above 44.00 kg.This study indicates that for constructing the breeding⁃propagation system of Guanling Yellow cattle,elite Guanling Yellow cattle should be adopted as dams and Simmental cattle as sires for the first three generations of crossbreeding.Limousin cattle can be used as sires for the fourth⁃generation crossbreeding.关键词
