Abstract: The aim of this study is to determine the productive performance, body condition score and exterior dimensions of Mouton Charollais sheep. The object of study are the female breeding animals born in the period 2019-2021 in the herd raised at the Agricultural Institute – Stara Zagora. Live weight was recorded from birth to 2.5 years of age, and prolificacy – at first lambing. The average value of the trait live weight by age, year and type of birth was calculated. Body condition score was determined at the ages of 12, 18 months and 2.5 years using a five-point system. The data were processed using program Statistica for Windows. As a result of the conducted research, it was established that: the year of birth and production of female animals influence the level of the trait live weight, as at certain ages the differences are mathematically proven; the obtained values for the BCS and the exterior dimensions of the animals show the tendency of being the highest at the age of 2.5 years, when the animals almost complete their growth and development. The morphological profile of animals at all analyzed ages is an indicator of their very good physiological condition.
