Correlation between Wool Color and Early Growth Performance in Prolifci Suffolk-Altui F2 Hybrid Lambs
摘要
Abstract
To investigate the correlation between wool color and early growth performance in lambs,a study was conducted using a resource population of F2 hybrid lambs produced from multiple birth of Suf-folk and Altay sheep.The wool color of the lambs was observed and recorded,and the initial birth weight and weights at 1~6 months of age were continuously measured for lambs of different coat colors.Statisti-cal analysis was performed to assess the growth differences among lambs of different coat colors.The re-sults indicated that the F2 lamb population comprised 5 coat colors,including white,black,gray,brown and mixed colors.The proportion of white lambs was the highest,while brown and black had the lowest proportion.The difference in birth weight of the five coat colors was not significant(P>0.05).At one month of age,the body weight of white male lambs was significantly greater than that of female lambs(P<0.05).At 2 months of age,the body weight of white and mixed male lambs was significantly greater than that of female lambs(P<0.01),and that of black male lambs was significantly greater than that of female lambs(P<0.05).At 3 months of age,the body weight of mixed male lambs was significantly grea-ter than that of female lambs(P<0.01),and the body weight of white,black,and grey male lambs was significantly greater than that of female lambs(P<0.05).At 4 months of age,the body weight of black,grey and mixed male lambs was significantly greater than that of female lambs(P<0.05).At five months of age,the body weight of white and mixed male lambs was significantly higher than that of female lambs(P<0.05).As the age of lambs increased,the cumulative growth and absolute growth of lambs of the five wool colors gradually increased.The daily wight gain of white lambs was significantly higher than black lambs at 2 months of age(P<0.01).At 3 months of age,the cumulative growth of white lambs was sig-nificantly higher than that of black lambs(P<0.05).At 5 months old,the cumulative growth of black lambs was significantly higher than that of brown lambs(P<0.05).These findings suggest that wool col-or influences the early growth and development of F2 hybrid lambs,but does not affect body weight chan-ges between sexes.White lambs exhibit faster early weight gain and growth.The research results provide a basis for the genetic improvement of local sheep breeds.关键词
