摘要
[Objectives]In order to better understand the performance of Kongshan cattle,their growth and development was analyzed.[Methods]The body weights of 106 kongshan cattle at different month ages were measured,and the growth curves and body measurement indices of Kongshan cattle after one year old were analyzed by SPPS18.0.[Results]Kongshan cattle have good body shape.Compared with 1985,the performance of body measurements and weight was improved significantly;and the body measurements and body weight of Kongshan cattle increased significantly after 24 months old,indicating that Kongshan cattle still have good fattening performance in adulthood.[Conclusions]This study analyzed the growth and development laws of Kongshan cattle and the status quo of the population,and will provide some help for the selection and utilization of Kongshan cattle breed more intuitively.
