Abstract

In the article, rams are inseminated with seeds obtained from them in order to study the pedigree, valuable traits and characteristics of rams of different ages. The manifestations of flower types of the obtained generations and their belonging to flower types were studied. In the study, it was observed that in the offspring of rams aged 7.5-8.0 months, belonging to the semicircular pen type was higher than in the offspring of rams in the experimental group of the same age. Pedigree rams aged 17.5-18.0 years differed from rams of all groups in that their ability to pass on their traits was superior. Generations of rams aged 17.5-18.0 years also showed high results in terms of belonging to the elite 1st and 2nd classes
