| Carcass traits of twenty Texel x Ile de France crossbred lambs slaughtered after weaning (52 days of age), or at 25, 30 and 35kg live weight were evaluated. Lambs were placed in individual stalls (1.5m²) and fed ad libitum with a diet composed of sorghum silage (Sorghum bicolor (L.) Moench) and a concentrate mix (ground corn, soybean meal, calcium carbonate and salt). Commercial dressing percentage was related quadratically with slaughter weight, being highest in lambs slaughtered after weaning. Real dressing percentage increased linearly. Shoulder proportion decreased with slaughter weight, whereas leg, rib and neck proportions remained constant. Carcass fat was positively correlated to the slaughter weight. Slaughter of feedlot Texel x Ile de France... |

| Foi avaliado o crescimento alométrico de ossos, músculos e gordura, e das regiões da carcaça de cordeiros Texel × Ile de France, terminados em confinamento. Vinte cordeiros, machos não-castrados, foram desmamados aos 42 dias de idade (15,9 ± 2,1kg de peso vivo) e confinados em baias individuais recebendo alimentação ad libitum. Destes, cinco foram abatidos 10 dias após o desmame e, os remanescentes, aos 25, 30 ou 35kg de peso vivo. Para determinação do crescimento alométrico dos cortes e tecidos foi utilizada a equação exponencial Y = aXb, transformada logaritmicamente em um modelo linear. Observou-se crescimento precoce (b = 0,89) da paleta, ao passo que a perna, a costela e o pescoço apresentaram crescimento isogônico (b = 1,00, 1,03 e 1,11,... |

| Twenty 11/16 Texel x 5/16 Ile de France crossbred lambs were slaughtered at different body weights to evaluate the growth of their non-carcass components. Animals were weaned at 42 days of age (15.9 ± 2.1 kg of body weight), housed in individual stalls, and fed ad libitum. After ten days of an experimental adaptation period, 5 lambs were slaughtered. The remaining lambs were randomly assigned to one of three following slaughter weights: 25, 30 or 35 kg of body weight at fast. At slaughter, all body components were individually weighed and expressed as percentage of the empty body weight. To determine allometric growth of individual components, the exponential equation Y = aXb was logarithmically transformed and used. Proportions of feet and head decreased,... |
