Abstract

CEYHAN, A., H. HANOGLU, T. SEZENLER and I. ERDOGAN, 2008. The improvement studies on mutton sheep for Marmara region conditions. 2. Fattening and carcass characteristics of lambs. Bulg. J. Agric. Sci., 14: 606-615

The purpose of this study was to compare the fattening performance, slaughter and carcass characteristics of lambs which were produced by crossbreeding with Kivircik sheep, the local breed in the Marmara region with German Black-Headed Mutton (GBM), the mutton breed which import from Germany. Forty lambs, the live weights of which were around 25.0 kg, were divided into 4 groups according to genotype and sex at the beginning of the fattening period. The average daily live gains were found 279, 210, 283 and 201 day/g, and fed conversion efficiencies were 5.018, 6.286, 4.854 and 6.197 kg, respectively in genotype groups of the Bandirma-I male, female, the Bandirma-II male and female lambs. The crossbred male lambs gained weight faster and consumed less feed per unit weight gain during the fattening program than the female lambs. Whereas, there were no fattening and carcass traits differences between crossbreds Bandirma-I and Bandirma-II genotype lambs.
