Abstract

Path analysis is applied to identify directed dependencies between a set of variables and used 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 Bafra ewe with same live weight and parity. 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<0.05). Additionally, the indirect effects of PW on birth weight were found statistically significant (p<0.05). While the PE variable was found with the highest direct effect (0.602) on BW, the highest total indirect effect (-0,468) on BW was found in the PW variable. The direct effect (-0.046) of the TCN variable was lowest on BW. Also, the indirect effect (0.093) of the PE variable was lowest on BW. The results showed that PW and PE were the most explanatory variable for the birth weight of Bafra lambs.

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

Abstract

Path analizi, bir dizi değişken arasındaki yönlendirilmiş bağımlılıkları tanımlamak ve ıslah uygulamalarını iyileştirmek için hayvan yetiştiriciliğinde uygulanmaktadır. Dolayısıyla bu çalışmanın amacı, Bafra koyun ırkında bazı plasental özelliklerin, kuzu doğum ağırlığına doğrudan ve dolaylı etkisini path analizi kullanarak incelemektir. Bu amaçla kuzu doğum ağırlığı ile yedi plasental özellik
(plasenta ağırlığı; PA, toplam kotiledon sayısı; TKS, toplam kotiledon yüzey alanı; TKYA, kotiledon verimliliği; KV, toplam kotiledon hacmi; TKH, hacimsel kotiledon verimliliği; HKV, plasenta etkinliği; PE) arasındaki ilişki 40 baş tekiz doğum yapmış, benzer canlı ağırlığa ve doğum sayısına sahip Bafra ırkı koyunda incelenmiştir. Kuzu doğum ağırlığı (DA), kuzu cinsiyeti ve plasental ölçümler doğumdan sonraki 12 saat içinde kaydedilmiştir. Çalışmada PE'nin doğum ağırlığına direkt etkisi istatistiksel olarak anlamlı bulundu (p<0.05). Ayrıca PA'nın doğum ağırlığı üzerindeki dolaylı etkileri istatistiksel olarak önemli olduğu tespit edilmiştir.
(p<0.05). DA üzerinde en yüksek doğrudan etki (0,602) PE değişkeninde bulunurken,
DA üzerinde en yüksek toplam dolaylı etki (-0,468) PA değişkeninde tespit
edilmiştir. DA üzerine doğrudan en düşük etki TKS (-0.046) değişkeninde, dolaylı
en düşük etki ise PE (0.093) değişkeninde tespit edilmiştir. Çalışmanın sonuçları,
Bafra kuzularının doğum ağırlığı için en açıklayıcı değişkenin PA ve PE olduğunu
göstermiştir.
