Yalova Genotipinin Morfolojik Özellikleri Üzerine Bazı Çevre Faktörlerinin Etkileri

Abstract

Objective: This study aimed to determine the live weight, the body measurements and their morphological features, and the effect of some environmental factors on morphological characteristics of Yalova sheep.Materials and Methods: The research material was consisted of 1-5≤ year old 250 ewes from 5 flocks and 1-4 year old 70 rams from 13 flocks. Live weight, withers height, back height, rump height, body length, tail length, rump width, chest width, chest depth, chest girth, thigh circumstances, cannon bone girth, head length, head width, forehead width, ear length and ear width of Yalova genotype was measured.Results: The average live weight of Yalova genotype was found as 55.63 and 85.75 kg for ewes and rams, respectively. Overall means of some characters of ewes were found as withers height, back height, rump width, body length, rump width, chest width, chest depth, chest girth and tail length 71.30, 70.40, 71.21, 71.43, 22.70, 21.53, 32.72, 93.41 and 20.50 cm, respectively. The effect of flock factor for ewes were found to be statistically significant on rump height (p<0.05) and body length, (p<0.01), and on all of the other examined features (p<0.001). For ewes, the age factor was statistically significant on live weight, chest depth, chest girth, head length (p<0.001) and ear length (p<0.05).Conclusion: Yalova genotype was revealed morphological characteristics different from pure Kıvırcık sheep. Besides Yalova genotype is different from other indigenous breeds due to its short tail with low fleece or no naked tail.
