罗布羊生长发育规律及其与体尺相关性研究
Study on growth and development regularity and its correlation with body size of Lopnur sheep
摘要
Abstract
To study the growth and development patterns of Lopnur sheep and their correlation between body weight and body size in Ruoqiang County,Xinjiang,471 healthy Lopnur sheep aged 0-12 months were selected under grazing condition.Their body weights,body lengths,body heights,chest circumferences,chest depths,chest breadths,and tube circumferences were measured.The data were analyzed using SPSS 25.0 software,employing growth curve models including Logistic,Gompertz,and Von Bertalanffy for fitting analysis,as well as to examine the correlation between body weight and body size of newborn male and female lambs.The results indicated that from 0-12 months of age,both male and female Lopnur sheep exhibited a significant growth trend in body weight and measurements.Significant differences were observed in the indicators of body weight and measurements between males and females across different months of age(P<0.05).The three growth curve models provided a good fit for the growth and development pattern of Lopnur lambs(R2>0.95),with the Von Bertalanffy model demonstrating a superior fit compared to the Logistic and Gompertz models.The inflection points for body weight in rams and ewes determined to be 1.53 and 1.61 months of age,respectively.A highly significant positive correlation was found between body weight and body length,chest circumference,chest width,and tube circumference in newborn Lopnur rams(P<0.01).Similarly,a highly significant positive correlation was observed between body weight and body length,body height,chest circumference,and chest depth in ewes(P<0.01),along with a significant positive correlation with chest width(P<0.05).Therefore,when selecting and breeding Lopnur sheep,it is recommended to choose males and females with excellent body length,chest width and chest depth indices.关键词
