Abstract

BOIKOVSKI, S., N. STANCHEVA, G. STEFANOVA and D. DIMITROV, 2002. Fattening abilities of lambs from the Newly created milk sheep breed in Bulgaria. Bulg. J. Agric. Sci., 8: 645–648

The objective of the present study was to investigate the fattening abilities of lambs from the Newly created milk sheep breed, intensively fattened to 40 kg pre-slaughter live weight, with a view to future selection and meat production.
It was established that the average daily gain of the lambs was comparatively high (302 g). The lambs had high meat heritability at intensive fattening to 40 kg live weight. The lamb was drier, rich in protein and minerals, with larger fibers and loose and mucous tissue among the muscles in the carcass. Physical traits and chemical meat composition of the lambs fattened to 40 kg, did not show any significant differences which could crucially change meat quality.

Key words: average daily gain, slaughter analysis, carcass weight, physical traits and chemical composition
