This study was conducted on 693 lambs born between 2019 and 2021 in an Akkaraman sheep farming registered with the 'National Small Ruminant Breeding Project' in Çankırı Province. The study aimed to investigate the distribution of lamb births throughout the day and the relationship between birth times and lamb sex, birth type, birth year, and lamb mortality at birth. For this purpose, the 24 hours of the day were divided into four equal segments of six hours each: 1. night (00:01-06:00), 2. morning (06:01-12:00), 3. afternoon (12:01-18:00), and 4. evening (18:01-00:00). Lamb births occurred most frequently at night, accounting for 39%, followed by morning (23.1%), evening (20.2%), and afternoon (17.7%). It was observed that lamb births were highest during the night for both female (42.8%) and male (35%) lambs, as well as for single (42.0%) and twin (30.9%) births. It was noted that births in 2019 (42.0%) and 2020 (30.9%) occurred most frequently during the night, while in 2021 (29.4%), they occurred most frequently in the evening. The highest rate of lamb mortality at birth was observed during the afternoon hours (4.1%). According to the Chi-square (χ2) analysis results, the effect of birth type (P=0.023) and birth year (P=0.001) was significant, while the effect of gender and lamb mortality at birth was found to be not significant. The study indicates that lamb births in Akkaraman sheep are concentrated during the night, providing an opportunity for farmers to be prepared during birth, and to increase lamb health and farm productivity.
