Studies on the possibility of improving lamb production by two-way and three-way crossbreeding with German Black-Headed Mutton, Kivircik and Chios sheep breeds - 1. Fertility, lamb survival and growth of lambs

Abstract

The aim of this study was to compare the fertility of ewes and the survival and growth traits of lambs which were produced by two-way and three-way crossbreeding with Kivircik sheep, the predominant breed in the Marmara region, Chios sheep. the most prolific breed in the region and German Black-Headed Mutton (GBM), the mutton breed which exhibits the best adaptation to the environmental conditions of the region.
