Abstract

It was studied live weight of young stallions and fillies at the age of 6 months from breeding farms: OOO “Signal” of the Altai region (n=56), SEC “Amuh’ (n=65) and “Kyrlyk” of the Republic of Altai (n=123). A comparative assessment of live weight of offspring depending on the age of sires was done. It was revealed the tendency of increase in live weight of progeny with increase in age of sires from 5 to 10 years, from 205 to 223 kg, respectively. By the method of one-factor dispersion analysis of variance it was found out that the origin by sire had more sufficient effect on live weight of offspring at the age of 6 months ( = 16,7-24,1%), than age of stallions ( = 5,3-7,4%).
