In this study, it was aimed to keep records of productivity in herds and to improve live weight and fertility based on the evaluation of these records. Although it changes according to the years (2017-2021), it has been studied with animal material that will not exceed the total number of 6300 heads. Birth weights and weaning (90th day) weights of the herds were recorded. The average birth weight was 2.69 kg in the 5-year period. The birth weight by years was determined as 2.99, 2.71, 2.61, 2.76 and 2.69 kg, respectively. Mean birth weights vary according to year, maternal age, birth type and sex (P<0.01). The average weaning weight was determined as 20.91 kg. Average weaning weights vary according to year, maternal age, birth type and sex (P<0.01). Lambing rate was found to be 86 % on average. Litter size is 0.83. Fecundity is 1.05. Infertility rate was determined as 20%. The average survival rate was determined as 93%. As a result, it has been revealed that there have been improvements in terms of weaning weight and fertility in herds over the years.
