G. da  aDiferentes dietas e pesos ao abate na produção de órgãos de cordeiros.  c2003  a0 experimento foi conduzido com o objetivo de avaliar os pesos e porcentagens de órgãos em relaçao ao peso vivo ao abate (PVA), ao peso de corpo vazio (PCV) e ao peso total dos órgãos (PTO) de cordeiros inteiros 1/2 Ile de France 1/2 Ideal confinados, recebendo dietas com relações volurnoso: concentrado de 50:50 e 30:70 e abatidos aos 30 ou 34 kg. Os parâmetros mensurados foram: língua, pulmões com traquéia, coraçao, figado, pâncreas, timo, tireóide, adrenal, rins, testículos, baço, diafragma, bexiga, pênis e glândulas anexas. Os resultados obtidos revelaram diferenças entre os pesos ao abate nas porcentagens de língua, coraçao, pulmões com traquéia, diafragma, pâncreas, tireóide, baço e glândulas anexas em relaçao ao PVA; nas porcentagens de língua, pulmões com traquéia, figado, pâncreas, baço e glândulas anexas em relaçao ao PCV e nas porcentagens de pulmões com traquéia, figado, pâncreas, tireóide, baço e glândulas anexas em relaçao ao PTO. Dietas com diferentes relações volumoso: concentrado afetararn apenas as porcentagens de pâncreas em relaçao ao PVA, ao PCV e ao PTO. Verificaram-se interações entre relaçao volumoso: concentrado e peso vivo ao abate nos pesos dos pulmões com traquéia, figado, pâncreas, tireóide e glândulas anexas.   [Different diets and slaughter weights affecting organ production of lambs. R. Bras. Zootec. [online]. 2003, vol.32, n.6, suppl.1, pp. 1792-1799. ISSN 1806-9290].   Abstract: The objective of this research was to evaluate weights and percentages of some organs in relation to live weight at slaughter (LWS), empty body weight (EBW) and total organs production (TOP) of intact 1/2 Ile de France 1/2 Polwarth male lambs. The lambs were finished in feedlot and fed diets with roughage:concentrate ratios of 50:50 and 30:70 and slaughtered at 30 or 34 kg. Tongue, lungs with trachea, heart, liver, pancreas, thymus, thyroid, adrenal, kidneys, testicles, spleen, diaphragm, bladder, penis and accessory glands were measured. Differences among treatments on the percentages in relation to LWS of the following organs: tongue, heart, lungs with trachea, diaphragm, pancreas, thyroid, spleen and accessory glands were observed. In relation to EBW, differences on the percentages of tongue, lungs with trachea, liver, pancreas, spleen and accessory glands were observed. Percentages in relation to TOP of lungs with trachea, liver, pancreas, thyroid, spleen and accessory glands also showed differences among treatments. Pancreas was the only organ that was affected by the diets with different roughage:concentrate ratios, when expressed as a percentage of LWS, EBW or TOP. Interactions between roughage:concentrate ratio and slaughter weight for lungs with trachea, liver, pancreas, thyroid and accessory glands were observed.  aCarcaça  aConfinamento  aCordeiro  aOvino  aMiúdos  aNão componente de carcaça  aPeso ao abate1 aGASTALDI, K.
