Abstract
In this study, data recorded in 1981-2008, which belonged to body measurements of purebred Turkishand Arabian horses raised at Sultansuyu State Farm were used. Heart at withers, heart girth, cannon bone andbody length measurements at different growth stages (birth, 6., 12., 18., 24., 36., 48. mount) compared in respectof sex and genetic parameters were estimated. Effects of both age and sex were found to be significant (P<0.05) onall traits. In general, the phenotypic correlation coefficients between the investigated traits were found significantly(P<0.05), excluding correlations between birth weight and other trait.The highest and lowest heritability and repeatability estimates for these traits were found to be 0.07-0.87 and0.16-0.87 respectively and interpreted as moderate-high. The lowest value of heritability was determined for heartgirth in birth (0.07) and, the highest heritability value for cannon bone in 6th month (0.87). The lowest value ofrepeatability was determined for heart girth in 6th month and cannon bone in 12th month (0.16), and, the highestrepeatability value for body length in 6th month (0.87). The fact that the degree of heritability of other features ismoderate-high indicates that the mass selection can be successful in terms of other features.
Özet
Bu çalışmada, Sultansuyu Tarım İşletmesinde yetiştirilen Türk Arap Atlarının vücut ölçülerine ait 19812008 yıllarında tutulan kayıtlar kullanılmıştır. Cidago yüksekliği, göğüs çevresi, İncik çevresi ve beden uzunluğuna ait ölçüler doğum, 6., 12., 18., 24., 36., 48. aylarda tespit edilmiş, hayvanlar cinsiyet gruplarına ayrılarak karşılaştırılmış ve genetik parametre tahminleri yapılmıştır. Hem yaşın, hem de cinsiyetin incelenen özelliklere etkisi önemli bulunmuştur (P
