Data on 4487 Turkish Saanen kids from 176 bucks and 1318 dam-goats, obtained from the Turkish Saanen goats in the Izmir region and collected between 2018 and 2019, were analyzed to examine the effect of genetic and non-genetic factors on growth traits. The average birth weight of the kids was determined as 3.33 ± 0.68 kg, the average W60 was 13.06 ± 2.94 kg, the average WW was 18.38 ± 4.14 kg, and the average PreWDG until weaning was 0.17 ± 0.04 g. Model 1, which does not account for the maternal effect, and Model 2, which includes the maternal effect, were used in the estimation of genetic parameters. The heritability estimates of BW, W60, WW, and PreWDG ranged from 0.05 to 0.59 in both models. It is recommended to consider the maternal effect as well as the environmental factors in the selection program for the best early breeder selection of kids growing alongside their mothers until the weaning period.
对2018年至2019年间从伊兹密尔地区的土耳其萨能山羊中获取的、来自176只公羊和1318只母羊的4487只土耳其萨能羔羊的数据进行了分析，以研究遗传和非遗传因素对生长性状的影响。羔羊的平均出生体重确定为3.33±0.68千克，平均60日龄体重为13.06±2.94千克，平均断奶体重为18.38±4.14千克，断奶前平均日增重为0.17±0.04克。在遗传参数估计中使用了不考虑母体效应的模型1和包括母体效应的模型2。在两个模型中，出生体重、60日龄体重、断奶体重和断奶前平均日增重的遗传力估计值在0.05至0.59之间。建议在选择计划中考虑母体效应以及环境因素，以便在断奶期前与其母亲一起生长的羔羊中选出最佳的早期育成者。
