Frangos de corte das linhagens comerciais Arbor Acres (AA), Pilch (PL), Cobb (CB) e Hubbard (HB) foram avaliados para comparar caracteristicas de desempenho e carcaca. O experimento constou de 3 grupos: machos (M), femeas (F) e misto (M+F). As caracteristicas avaliadas foram: consumo de racao (CR), ganho de peso (GP), conversao alimentar (CA) e viabilidade (VB) até 49 dias. Foi utilizado um grupo de 20 aves por parcela como unidade experimental. Aos 50 dias de idade, retiraram-se ao acaso uma ave de cada parcela M e F e um macho e uma femea da parcela MF, para avaliacao do rendimento de carcaça (RC), porcentagem de gordura abdominal em relacao ao peso vivo (PGA) e ao peso da carcaca eviscerada (PCE). Diferencas significativas de CA, (P < 0,05) foram observadas entre linhagens, tendo a linhagem PL apresentado o melhor resultado. Quanto as caracteristicas de carcaca, a linhagem CB apresentou menor PC e a AA menor RC, em relacao as demais. O efeito do grupo foi significativo (P < 0,05) sobre todas as caracteristicas avaliadas, com excecao da VB. As femeas apresentaram menores PV, PC e RC, e maiores PGA e PCE que os machos. Correlacoes fenotipicas significativas foram observadas entre PV e PC (r=0,98); PCE e RC (r=0,52); PV e RC (r=0,35). Resultados semelhantes foram encontrados, quando se levou a linhagem em consideracao, com excecao da HB, na qual a correlacao entre PV e RC nao foi importante. |

A population of 1398 Canchim (CA) cattle was genotyped to asses the association of na insulin-like growth factor 1 (IGF1) gene microsatellite with phenotypic variation and estimated breeding values of pre-weaning, weaning and post-weaning growth traits. After na initial analysis, the IGF1 genotype only had a significant effect (P < 0.05) on birth weight (BW) and weaning weight adjusted lo 240 days (WW240). For these two traits, direct and maternal breeding values were estimated using the restricted maximum likelihood (REML). Two analyses were carried out. In the first (Model I), all fixed effcts were fitted. In the second (Model II). The fixed effect of the IGF1 genotype was omitted. The estimated genetic and phenotypic components of variance were similar for every trait in both models. For Model I estimated direct and maternal herilabilities were 0.26 and 0.16 for BW and 0.23 and 0.14 for WW240 respectively. The genetic and phenotypic correlations between BW and WW240 were 0.38 and 0.38 (Model I) and 0.19 and 0.38 (Model II) respectively. Fifty animais were classified according to their direct and maternal breeding values for both traits. Spearman rank-order correlation between animal rankings in the two models was used 10 asses the effect of including the IGF1 genotype in the model. Non-significant values from this correlation were indicative of a difference in breeding value rankings between the two approaches. The IGF1 gene was found to be associated with phenotypic variation and breeding values in the early of growth.
