Fattening Performance and Careass Evaluationof Markaraman, Meriııo, Avassi Purebreds and Various Crossbreds of Those. 1- Their Response to a Ratian Canlanining 50 % Concentrate An experiment was conducted in order to determine the response of 9 different genotypes of lambs to fattening. The genotypes used were a native fat tailed sheep called Morkararnan (K), Merino (M), F ı (KxM), F 2 (F1 x F ı), F 3 (F z x F2), gradjng up to Me· rİno (Gı> Gz, G 3), Awassİ x Merİno (IM), Awassi x Morkaraman (IK) and Awassi x KM (I x KM). One hundred nintynine lambs were fed aration eon· taining 50 % concentrate for about ıo weeks. Feed and water were supplied at ad !ibitum leveI. The highest average daily gaİn (206 gm) obtained from F ı's, and the lowest 'one obtained from Morkaramans (~50 gm), Merino, F2. IM and I x KM also responded fairly good to the raticn whereas grading up to' Merino (G~, Gz, G3) and F3 were not as good as the others from the stand point' of average daily gain and feed effieieney. The average daily gaİn obtained from Fı (206 gm), F 2 (197 gm), i x MK (188 gm), M (182) and IM (181 gm) was signifieant1y (P< 0.01) higher than both Morkaramans' (150 gm) and IK (142 gm) crossbreds. 1'he F 1 crossbreds gained more than F3 erossbreds (166 gm) also (p < 0.05). Therefare it was eoncluded that F 1 comes ftom a native breed sueh as Morkaraman and Awassi) and Merino show signs of' heteroisis and the value of heterosis does not change too mueh İn F2. However, F ı obtained from the two native breeds, Morkaraman and Menno, does not show any sign of heterosis. Hot earcass weights were almost the same for aLL genotypes ranging from 20 to 24 kg. Dressing percentages were between 44 % and 48 % for all groups. The other parameters , were diseussed İn deail in this article.
