Sunulan çalışma Van'da kesilen boğaların ırkları, yaşları, karkas ağırlıkları ile testisepididymis ölçüleri ve patolojilerinin belirlenmesi amacıyla yürütüldü. Çalışma materyalini Van îl'i Et- Balık Kurumu Kombinasına kesim için getirilen yaşları 2-3 arasında değişen farklı ırktan DAK. Esmer. GAK, Holştayn. Melez. Simental. Yerli Kara 1133 boğa oluşturdu. Damızlık olarak seçilecek boğalarda özellikle ırk-testis büyüklüğii.testis büvüklüğü-karkas ağırlığı, testis büvüklüğü-kauda epididymis çapı ve uzunluğunun bir kriter olabileceği ve vücut gelişimine paralel olarak ırk özellikleri ile birlikte testis ölçülerinin de değerlendirilmeye alınmasında büyük yarar olacağı kanısına varıldı

Studies on Breed, Age, Carcas Weights, Testes and Epididymis Sizes and Abnormalities in Buils Slaugtered in Van

Öz

In the present study. breed. age and carcas weights of buils slaughtered in the city of Van were compared with testesepididymis size and abnormalities. In this study 1133 buils aged between 2 and 3 and different breed East Anatolia Red. Swiss Brown. Southeast Anatolia Red, Holstein. Cross Breed. Simmentai. Anatolia Black slaughtered in the Meat and Fish Instituation in the city of Van were used as material. Results in this study showed that especiallv breed and testes size, testes size and carcas weight. testes size and cauda epididymis diameter and lenght can be an important criteria in choosing buils for breeding. Therefore. together with breed characlers. testes measurements paraleli to bodv development belived to be useful in choosing buils for breeding
