Kıvırcık koyunların ithal etçi koçlar ile (Hampshire Down, Siyah başlı Alman, Lincoln) melezlenmesi sonucu elde edilen genotip grupların verim özellikleri

Abstract

This research was conducted to determine growth and survival characteristics of F-1 and F-2 genotype groups of lambs and reproduction characteristics of F-1 genotype groups obtained from crossbreeding Kivircik to Hampshire Down, Lincoln and Blackhead German mutton sheep breeds raised at Bandirma Sheep Research Institute. Differences between reproductive characteristics of Hampshire Down x Kivircik and Blackhead German x Kivicik F-1 crossbred sheep were not significant. Effects of birth type and sex on weights at birth, 60., 120. and 180 days in all genotype groups were statistically significant (P<0.01). Differences between genotype groups for survival rate up to 60., 120, and 180.days of F-1 and F-2 crossbred lambs were found significant.
