Bafra Koyunlarında Kuzu Doğum Ağırlığı Üzerine Plasental Özelliklerin etkisinin Path Analizi ile belirlenmesi

Path analysis is used to describe the directed dependencies among a set of variables and applied in animal breeding to improve breeding practices. Therefore, the aim of this study was to examine the direct and indirect effect of some placental traits on lamb birth weight born to Bafra sheep breed using path analysis. For this aim, the relationship between lamb birth weight and seven placental traits (placental weight; PW, total cotyledon numbers; TCN, total cotyledon surface area; TCSA, cotyledon efficiency; CE, total cotyledon volume; TCV, volumetric cotyledon efficiency; VCE, placenta efficiency; PE) were studied in 40 singleton - bearing ewe. Birth weight (BW), lamb sex, and placental measurements were recorded within 12 h after parturition. The direct effects of PE on birth weight were found statistically significant (p
