The research on the influence of age on the reproduction indices in Karakul of Botoșani sheep was carried out by processing the data found in the breeding and calving registers, the lamb register and the existing breeding registers within the S.C.D.C.O.C. Popăuți for the period 2017-2019. Following the research carried out on the influence of the age of Karakul of Botoșani sheep on the reproduction indices, the obtained results indicated a statistically significant link between the age batch of which the sheep belong and the reproductive indices analyzed. The data obtained indicated values of higher reproduction rates in the 52-56 months’ age batch (107.8% fertility rate, 96.4% fecundity rate, 95.5% birth rate and 112.9% prolificacy rate) compared to the results obtained by sheep in the 16-21 months’ age batch (94.6% fertility rate, 90.6% fecundity rate, 89.1% birth rate and 106.1% prolificacy rate).
