Abstract :In this study, the distribution of birth data during the day insert ignore into journalissuearticles values(24 hours); of 651 lambs born in 2019-2022 of Bafra sheep reared in a private sheep farm in Kızıllı village of Antalya province was investigated. In the study, the effects on the distribution of births during the day and the characteristics of lambs such as birth type, sex, difficult and normal births, and dam’s lactation number were investigated. The 24 hours were divided into four equal periods such as 06:01-12:00 = 1, 12:01-18:00 = 2, 18:01-00:00 = 3, and 00:01- 06:00 = 4 to evaluate the distribution within the day. χ2 insert ignore into journalissuearticles values(Chi-square); test analysis was used to determine whether the characteristics such as, birth type, sex, difficult and normal births, and dam’s lactation number affected the distribution of births during the day. As a result of the analysis, the distribution of a total of 651 lamb births during the day was observed as 260 heads insert ignore into journalissuearticles values(39.9%); at 06:01-12:00, 199 heads insert ignore into journalissuearticles values(30.6%); at 12:01-18:00, 109 heads insert ignore into journalissuearticles values(16.7%); at 18:01- 00:00, and 83 heads insert ignore into journalissuearticles values(12.7%); at 00:01-06:00, respectively. In the first and second time periods between 06:01 and 18:00, 70.5% insert ignore into journalissuearticles values(459 heads); of lamb births occurred. The ratio and number of lambs in sex distribution were determined as 45.8% male insert ignore into journalissuearticles values(298 head); and 54.2% female insert ignore into journalissuearticles values(353 head);, respectively. The number and rate of lamb births of ewes in the first lactation comprised 366 heads and 56.2%, respectively. According to the χ2 test of the time periods of the births, the effect of the lamb\`s birth type insert ignore into journalissuearticles values(P<0.05);, difficult and normal births insert ignore into journalissuearticles values(P<0.05); and dam lactation number insert ignore into journalissuearticles values(P<0.01);, were statistically significant while the effect on the lamb\`s sex was found to be insignificant. As a result, considering the distribution of births during the day, it was seen that they were concentrated during the daytime hours. Being more careful in herd management during these hours will increase the profitability of Bafra sheep, which is one of the sheep breeds with high fertility.
