This study investigated changes in morphological indices, which were calculated based on body measurements, in crossbred hair goats raised on different farms. The study involved 240 female goats from five farms, one of which specialised in purebred hair goats. The following structural indices were calculated using 14 different morphological measurements taken from the animals: weight (A), body index (VI), width slope (GE), balance (D), height slope (YE), dactyl thorax index (DTI), body proportion (VO) and conformation index (CCI). The obtained data were then statistically evaluated. The results showed statistically significant differences between farms for body index (P<0.0001), balance index (P=0.0023), compact index 1 (P<0.0001) and compact index 2 (P<0.0001), weight (P<0.0001), width slope (P<0.0001) and dactyl thorax index (P<0.0001). The highest body index values (108.59 cm) and dactyl thorax index values (12.74 cm) were observed in enterprise 4, where crossbreeding was more intense. Negative correlations were observed between the body index and the compact indices (rVI-KI-1 = -0.67, P < 0.0001; rVI-KI-2 = -0.67, P < 0.0001), while positive correlations were observed with the weight estimation indices (rKI-1-A = 0.21, P = 0.0008; rKI-2-A = 0.21, P = 0.0008). There was also a strong negative correlation between body ratios and height slope (rVO-HE = -0.99; P < 0.0001).
The results demonstrate that crossbreeding significantly affects the morphological structures of goats, and that certain indices can be employed in breeding selection. It is concluded that the indices used in the study are sensitive to environmental and genetic effects when determining milk and meat production, therefore it is important to monitor conformation traits according to production objectives.

Bu çalışma, farklı işletmelerde yetiştirilen melez kıl keçilerinde bazı vücut ölçülerine dayalı olarak hesaplanan morfolojik indekslerdeki değişmeleri incelemek amacıyla yürütülmüştür. Araştırma, biri saf kıl keçisi işletmesi olmak üzere toplam beş farklı işletmede, 240 baş dişi keçi üzerinde gerçekleştirilmiştir. Hayvanlardan alınan 14 farklı morfolojik ölçü kullanılarak) yapısal indeksler hesaplanmış (Ağırlık (A), vücut indeksi (Vİ), genişlik eğimi (GE), denge (D), yükseklik eğimi (YE), daktil toraks indeksi (DTİ), vücut oranı (VO), konformasyon indeksi (Koİ), kompaktlık (Kİ-1/Kİ-2) ve elde edilen veriler istatistiksel olarak değerlendirilmiştir. Elde edilen bulgular; vücut indeksi (P<0,0001), denge indeksi (P=0,0023), kompaktlık 1 (P<0,0001) ve kompakt 2 (P<0,0001), ağırlık (P<0,0001), genişlik eğimi (P<0,0001) ve daktil toraks indeksi (P<0,0001) açısından işletmeler arasında istatistiksel olarak anlamlı farklılıklar bulunduğunu göstermiştir. En yüksek vücut indeksi (108,59 cm) ve daktil toraks indeksi (12,74 cm) değerleri, melezlemenin daha yoğun olduğu 4 numaralı işletmede gözlenmiştir. Kompaktlık indeksleri ile vücut indeksi arasında negatif (rVİ-Kİ-1=-0,67 (P<0,0001); rVİ-Kİ-2=-0,67 (P<0,0001)), ağırlık tahmin indeksleri ile pozitif korelasyonlar tespit edilmiştir (rKİ-1-A=0,21 (P=0,0008)/rKİ-2-A=0,21 (P=0,0008). Ayrıca vücut oranı ve yükseklik eğimi arasında güçlü negatif bir ilişki belirlenmiştir (rVO-YE = -0.99; P<0,0001).
Sonuçlar, melezlemenin keçilerin morfolojik yapıları üzerinde önemli etkileri olduğunu ve bazı indekslerin damızlık seçiminde kullanılabileceğini göstermektedir. Çalışmada kullanılan indekslerin, süt ve et tipi yönelimini belirlemede, çevresel ve genetik etkilere karşı duyarlılık gösterdiği, bu nedenle konformasyon özelliklerinin üretim hedeflerine göre izlenmesinin önemli olduğu sonucuna varılmıştır.
