Path analysis of the relationships between various body measures and live weight of American bronze Turkeys under three different lighting programs

Öz:

Hayvan ıslahı ve genetiğinde, sebep-sonuç ilişkilerinin bilinmesi seleksiyon hakkında önemli ipuçları verebilir. Sebep değişkenlerinin üzerinde durulan özelliklere katkılarının farklı olması, söz konusu özelliklere en fazla katkı yapan değişkenlerin belirlenmesini gerektirir. Bu çalışmada, Amerikan Bronz Hindilerinin tespit edilen dört özelliğinin (incik uzunluğu, göğüs uzunluğu, göğüs derinliği ve göğüs çevresi), 30. hafta canlı ağırlık üzerine doğrudan ve dolaylı etkileri iz katsayısı metodu (Path analizi) kullanılarak analiz edilmiştir. Analiz sonuçları, canlı ağırlık üzerine en fazla doğrudan etkiye sahip olan değişkenin incik uzunluğu değişkeninin olduğunu göstermiştir. Genel olarak, göğüs uzunluğu ve göğüs çevresi değişkenlerinin incik uzunluğu üzerinden olan dolaylı etkileri de daha yüksek bulunmuştur. Buradan hareketle, 30. hafta canlı ağırlığa en etkili değişkenin incik uzunluğu olduğu ve bunun modele dahil edilmesinin gerekli olduğu sonucuna varılmıştır.

Öz:

In animal breeding and genetics, knowledge of causal effects may provide valuable information on selection. Different contributions of explanatory variables to the traits indicate that the breeder has to choose the variable with the largest contribution in a selection effort. In this study, direct and indirect effects of four explanatory variables (Shank Length, Breast Length, Breast Depth and Breast Circumference) influential on live weight at week 30 in American Bronze turkeys were investigated using path analysis. Results of the analyses indicated that the direct effects of shank length were the largest on live weight. In general, indirect effects of Breast Length and Breast Circumference through Shank Length were highest among all indirect effects. Shank Length is the most influential variable and must be included in the model in estimating the live weight at week 30.
