In this study, the reproductive and growth performance of Akkaraman sheep between 2017-2021 were evaluated within the scope of the National Sheep and Goat Breeding Project in the Hand of the Public, which is being carried out in the province of Nigde. In the research, data obtained from 30923 animals in 22 farms in 7 villages in the central district of Nigde province were used. In the study, the effect of year, dam’s age, gender and birth type on birth weight (BW), live weight on day 60 (LW1), live weight on day 120 (LW2), daily live weight gain (DLWG) on day 120 were investigated. The effects of year, dam’s age, gender and birth type on BW, LW1, LW2, DLWG were found to be statistically significant. While the effects of year, dam’s age and gender were found to be statistically effective on SR, the effect of birth type was found to be insignificant. In the study, fertility, fecundity and litter size in Akkaraman lambs were determined as 0.92, 1.03 and 1.13, respectively. As a result, remarkable progress has been achieved in Akkaraman lambs in terms of performance characteristics (LW1, LW2 and DLWG) between 2017 and 2021.
This study aimed to determine the direct and indirect effects of the independent variables presented by the lactation lenght (LL), age of calving (CAGE), and daily milk yield (DMY) on the dependent variable of lactation milk yield (LMY) in Anatolian buffaloes. In this study, a total of 3761 LMY records of the 834 Anatolian buffaloes calving between 2012 and 2017 in Tokat province and around were used as the research material. In the study, the simple correlation coefficients between the dependent variable of LMY and independent variables were determined positive and significant (P<0.001). The research specified the direct determination coefficients of the independent variables of the LL, CAGE, and DMY on the dependent variable of LMY as 0.378, 0.004, and 0.350, respectively. The path coefficients related to LL, CAGE, and DMY were determined as 0.615, 0.021, and 0.592, respectively. Since the DMY and LL examined in the study had a high direct impact on the lactation milk yield, therefore it could be suggested that using these data as criteria in breeding programs conducted in the herds evaluated in the study will increase the success in the selections applied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
