Resumo: | With the objective of evaluating the isolated effects of genotype and of nutritional system, as well as the effect of the interaction between genotype and nutrition on quantitative and qualitative aspects of the meat production, sixty Polwarth male lambs and 51 Corriedale male lamb, born at August and September, raised in three different nutritional systems (native pasture, improved pasture e confinement) and slaughtered with 122 days of age, were examined. The animals were weighed before slaughtering and, after slaughtering, the following traits were measured: cold carcass weights, shoulder, hindquarter, rib and neck weights and the weight of bone, muscle and fat of the shoulder and the hindquarter. The percentages were obtained by calculation. The experimental design was a totally randomized in a 3x2 factors (nutritional systems and genotypes). There was interaction genotype-nutrition (P <0.05) for bone of the hindquarter and of the shoulder and for the shoulder fat. Except for the weight and percentage of the bone of the shoulder, for all the other parameters of weight and of carcass studied there was not genotype effect. The nutrition influenced significantly (P <0.05) all the parameters. KEY WORDS: Interaction genotype-nutritional system, lambs, regional composition, tissue composition. |

KEY WORDS: Interaction genotype-nutritional system, lambs, regional composition, tissue composition.Com o objetivo de avaliar os efeitos isolados de genótipo e de sistema nutricional, bem como o da interação genótipo x sistema nutricional sobre aspectos quantitativos e qualitativos da produção de carne ovina, utilizaram-se 60 cordeiros da raça Ideal e 51 da raça Corriedale, nascidos no mês de agosto e setembro, criados em três sistemas diferentes de alimentação (campo natural, pastagem cultivada e confinamento) e abatidos com 122 dias de idade. Os animais foram pesados antes do abate e de suas carcaças obteve-se o peso da carcaça fria, da paleta, da perna, do costilhar e do pescoço e, por cálculo, percentagem de paleta, da perna, do costilhar e do pescoço. A paleta e a perna foram desossadas e destes cortes obtiveram-se o peso de osso, músculo e gordura e, por cálculo, a percentagem desses tecidos. Desenvolveu-se o experimento em um delineamento inteiramente casualizado, em esquema fatorial 3x2 (sistemas nutricionais e genótipos). Houve interação genótipo-nutrição (P<0,05) para osso da perna e da paleta e para gordura da paleta. Com exceção da percentagem do osso da paleta, para todos os demais parâmetros não houve efeito de genótipo. O sistema nutricional influenciou significativamente (P<0,05) todos os parâmetros.
