Path analysis for determination of relationships between some body measurements and live weight of german fawn x hair crossbred kids

Bu çalışma path analizi kullanımı ile Alman Alaca x Kıl melezi oğlaklarının canlı ağırlıkları üzerine bazı vücut ölçümlerinin doğrudan, dolaylı ve toplam etkilerini incelemiştir. Bu amaçla kullanılan veri, toplam 40 baş Alman Alaca x Kıl melezi oğlaklarından alınan canlı ağırlık (CA), göğüs çevresi (GÇ), cidago yüksekliği (CY), ön sağrı genişliği (ÖS) ve vücut uzunluklarından (VU) oluşmaktadır. Araştırmada, oğlakların CA’sı üzerine GÇ, CY, ÖS ve VU’ nun etkileri istatistiki olarak önemli bulunmuştur. Ayrıca, CA üzerine VU’nun dolaylı etkisi en yüksek bulunurken, GÇ’nin hem doğrudan hem de toplam etkisinin CY, ÖS ve VU’na göre daha yüksek olduğu belirlenmiştir. Sonuç olarak, Alman Alaca x Kıl melezi oğlaklarının kesim dönemlerindeki hayvan başına karkas verimini arttırmak amacıyla, canlı ağırlık tahminlerinde göğüs çevresi ölçüleri kullanılmalıdır.

Anahtar Kelimeler:

vücut ölçümleri, karkas verimi, karkas, melez ırklar, tespit etmek, keçi, oğlak, canlı ağırlık, morfoloji, performans özellikleri

This paper investigated direct, indirect and total effects of some body measurements on live weights of German Farm x Hair crossbred kids using path analysis. For this aim, used data were live weight (LW), chest girth (CG), height at withers (HW), front rump width (FR) and body length (BL) measurements taken from totally 40 German Farm x Hair crossbred kids at weaning period. The results indicated that CG, HW, FR and BL had statistically important effects on LW of the kids. It was also determined that both direct and total effects of CG on LW were higher than the effects of HW, FR and BL, although the indirect effect of BL on LW was the highest. Consequently, with the aim of increasing carcass yield per animal in slaughtering periods, the chest girth measurements should be used to predict the live weight of the German Farm x Hair crossbred kids.

Keywords:
