RESUMO Objetivou-se estimar as exigências energéticas de borregas mestiças confinadas, alimentadas com níveis crescentes de concentrado na dieta. Foram avaliadas 36 borregas, com peso corporal inicial de 23,7±3,67kg. Seis animais foram abatidos no início do experimento para obtenção dos valores do grupo referência. Os demais (30 animais) foram distribuídos em cinco tratamentos: mantença (alimentação restrita com feno de capim Tifton) e suplementados com níveis crescentes de concentrado (20, 40, 60 e 80%) em base de matéria seca (seis animais por tratamento). As borregas foram abatidas quando atingiram 37,70±9,89kg. Os níveis de concentrado influenciaram a eficiência de utilização da energia metabolizável para mantença (km) e consequentemente as exigências... |

The aim of this study was to evaluate the effect of increasing levels of concentrate on the quantitative and qualitative carcass characteristics of feedlot ewes. Twenty-four crossbred ewes were randomly distributed in four treatments: (1) diet with 20%; (2) 40%; (3) 60%; and (4) 80% of concentrate. Animals were slaughtered when those receiving the diet with 80% of concentrate reached adult weight, at around 50kg LW. The data were analyzed by means of variance and regression analyses and correlations. The levels of concentrate increased live weight at slaughter linearly. Height at the withers and rump presented medium to high correlation (0.86). The correlation of loin eye area measured on the carcass and by ultrasound examination was 0.81, whereas for back... |

Six common bean cultivars were crossed in diallel and the segregant populations were assessed in the F2 and F3 generations to compare methodologies for parental selection in a breeding program based on hybridization. The cultivars involved in the diallel were A 114, A 77, ESAL 686, Milionário, Carioca, and Flor de Mayo. The segregant F2 and F3 generations were assessed on the experimental campus of the Universidade Federal de Larvas, in July 1994. It was found that the cultivars differed in their general combining ability (GCA). Flor de Mayo, which belongs to the Durango race, had the largest positive GCA estimate for grain field, and the cultivars from the Mesoamerican race, Milionário and A 114, the smallest GCA estimates. For flowering, the cultivar... |
