Note: LSM—least squared means; SE—standard error; BW—body weight; BH—body height; BL—body length; HHC—height at the hip cross; CD—chest depth; CW—chest width; PG—paunch girth; CC—cannon circumference. The row in bold represents that there is a significant difference in different genotypes of the same traits. a and b represent significant differences. The significance level was 0.05.
