İvesi kuzularında Sütten Kesim Ağırlığı ve Bazı Morfolojik Özellikler Arasındaki İlişkinin Path Analizi
Öz
Bu çalışmada, koyunların sütten kesim ağırlığı üzerine
sağrı yüksekliği, cidago yüksekliği, vücut uzunluğu, göğüs derinliği, göğüs
çevresi gibi bazı morfolojik özelliklerin doğrudan ve dolaylı etkilerini
belirlemek amacıyla path analizi kullanılmıştır. Çalışmanın verileri, Gaziantep
ilinde yetiştirilen 200 baş İvesi kuzulardan elde edilmiştir. Path analiz
sonuçlarına göre, cidago yüksekliği ve vücut uzunluğu değişkenlerinin İvesi
kuzularında sütten kesim ağırlığı üzerinde önemli etkiye sahip olduğu ve göğüs
çevresi ve vücut uzunluğunun İvesi kuzularında sütten kesim ağırlığını tahmin
etmede en uygun ölçümler ve pratik seçim için güvenilir bir kriter olarak
kullanılabileceği belirlenmiştir.

Path Analysis of the Relationship Between Weaning Weight and Some Morphological Traits in Awassi Lamb
Öz
In this
study, Path analysis was used to determine the direct and indirect effects of
some morphological traits such as wither height, sacrum height, body length,
chest depth, chest girth and chest width on the weaning weight of sheep. The
data was obtained from 200 heads of Awassi lambs raised in Gaziantep province.
The results of the path analysis indicated that the variants of sacrum height
and body length sustained the most significant effect on the weaning weight.
Consequentely, chest girth and body length were the most favorable measurements
to estimate weaning weight in Awassi and could be used as a reliable criteria
for practical selection in Awassi lambs.
