Year 2019, Volume: 33 Issue: 3, 227 - 230, 15.12.2019

Abstract

In this study, data on the daily distribution of births of Central Anatolian Merino sheep reared in Sheep Breeding Department of Bahri Dağdaş International Agricultural Research Institute was evaluated. In this study, the effects of damage, sex of lamb and type of birth on the time of birth in sheep were investigated. A day (24 hours) was divided into four timeframes as 22: 01-04: 00, 04: 01-10: 00, 10: 01-16: 00 and 16: 01-22: 00 in order to determine the time period in which births take place. Chi-square (χ2) test was used to determine whether the age, sex, and type of birth were effective on the distribution of births to the time periods during the day. As a conclusion, it was sind out that, in 2016, 78.09% of births were single and 21.91% twins. The sex ratio was 48.24% male and 51.76% female. The most frequent birth times were 10: 01-16: 00 (26.95%) and 04: 01-10: 00 (25.57%), the earlier birth times were 16: 01-22: 00 (23.93%) and 22: 01- 04:00 (23.55%). The effect of dam age and lamb sex on delivery time was significant (P<0.05), but the effect of birth type was not significant.
