弗莱维赫牛×荷斯坦牛F1代生长发育规律分析
Analysis of Growth and Development Law of F1 Generation of Flaevich × Holstein Cattle
摘要
Abstract
This study was conducted to investigate the growth and development performance of F1 gen-eration hybrids from Fleckvieh and Holstein cattle.The objectives were to elucidate the early growth pat-terns of the crossbreds,examine the correlations between body weight and body size traits,and provide re-liable foundational data for their selective breeding.A total of 638 calves from birth to six months of age were selected from a company in Shihezi City of Xinjiang for growth performance measurement.The col-lected data were subjected to statistical and correlation analysis.The results indicated that compared to the local Holstein cattle,the crossbred calves showed varying degrees of increase in body weight and body size measurements as they aged.Furthermore,a highly significant positive correlation(P＜0.01)was found between body weight and all body size indices in the F1 generation.Therefore,in practical cattle farming,the growth and development characteristics of the F1 generation can serve as a basis for formulating breed-ing strategies for crossbred cattle and for improving the performance of medium-and low-productivity Hol-stein cattle.This work provides foundational data for exploring a new dual-purpose(dairy-beef)production model,primarily focused on milk production with meat as a supplementary output.关键词
