| ABSTRACT The objective of this study was to investigate the multivariate relationship among body protein, fat, and macrominerals in Saanen goats of different sexes (castrated males, females, and intact males) using canonical correlation analysis. Individual records of 274 Saanen goats combined from 10 studies was used. Two sets of body constituents were established: the first one contained variables related to body protein or fat (canonical variate U) and the second contained variables related to body calcium, phosphorus, magnesium, sodium, or potassium (canonical variate V). Two canonical pairs were identified for each sex. However, irrespective of sex, first canonical pairs accounted for more than 87% of variance of the dependent variables, these only... |

| Foram conduzidos dois ensaios para medir os fluxos portal e visceral total de metabólitos em ovinos (peso vivo (PV) médio de 35 ± 3 kg) recebendo feno de capim-arroz (Echinochloa sp.) cortado aos 32, 46, 72 ou 90 dias de rebrota. Um dos ensaios foi realizado em quadrado latino 4 × 4 (ensaio 1) para avaliação dos quatro fenos e outro em quadrado latino 3 × 3 (ensaio 2), sem o feno do capim cortado aos 32 dias de rebrota. Os animais foram implantados com cateteres permanentes nas veias mesentérica e hepática. Sangue arterial foi acessado através de cateteres temporários na carótida. O fluxo de sangue portal e visceral foi estimado com base na diluição de paraminohipurato infundido continuamente em uma veia mesentérica. Na refeição prévia às amostragens, o... |

| The objective of this study was to evaluate the mobilization of nutrients in goats of different gestation types and pregnancy stages. Forty-four Saanen and Oberhasli goats were studied. The goats of each breed and gestation type (single or twin) were slaughtered at different gestational ages (80, 110, and 140 days of pregnancy), forming a completely randomized design in a 2 × 3 × 2 factorial arrangement (two breeds, three gestational ages, and two types of pregnancy). The slaughter procedure involved separating the empty body, mammary glands, uterus with membranes and fetal fluid, and fetus(es). For the females slaughtered at 140 days of pregnancy, blood was collected to analyze metabolites and hormones every 15 days during gestation. The dry matter (DM)... |

| Our objective was to evaluate the chemical composition, fermentation profile, and aerobic stability of cabbage silages treated with ground corn and inoculant. The evaluated treatments were: addition of 200, 300, 400, 500, and 600 g of ground corn per kilogram of cabbage (fresh matter basis), with or without a bacterial inoculant composed of Lactobacillus plantarumand Pediococcus pentosaceus. As expected, ground corn additions increased the dry matter (DM) content of cabbage silage, and high values were observed for the highest level of addition (540 g kg−1). Conversely, the crude protein, neutral detergent fiber, acid detergent fiber, and lignin contents decreased with ground corn additions. The in vitro dry matter digestibility coefficients increased... |

| Our objective was to investigate the effect of the replacement of aruana grass by gliricidia on the fermentative losses, chemical composition, and aerobic stability of silages. For ensiling, whole-crop aruana grass (75 d of growth) was chopped (275 g kg-1 dry matter - DM) and ensiled alone or associated with gliricidia (270 g kg-1 DM; 150 d of growth). For gliricidia, we used only the leaves and stalks to ensile. The evaluated treatments were different ratios of aruana grass to gliricidia (100:0, 75:25, 50:50, 25:75, and 0:100), with four replicates (mini-silos). The silage composed only of gliricidia exhibited a lower pH than the other silages. Dry matter recovery was not affected by the treatments, although effluent losses were affected. The replacement... |

| O objetivo deste estudo foi avaliar o método de multicateterização utilizado para estudar o metabolismo visceral em ruminantes. Quatro ovinos Ideal <FONT FACE=Symbol>´</FONT> Texel (peso vivo (PV) médio de 35 ± 2,5kg) foram implantados com cateteres permanentes nas veias mesentérica, porta e hepática. Sangue arterial foi acessado através de cateteres temporários implantados na carótida. A estimativa de fluxo de sangue portal e visceral foi feita com o uso do indicador paraminohipurato. Todos os cateteres mantiveram-se viáveis durante um período de no mínimo 45 dias. O fluxo de sangue visceral foi em média de 147l h-1 ou 4,2l h-1 kg-1 de PV, similar ao obtido em outros estudos com ovinos. Contudo, os dados de fluxo de sangue portal obtidos na... |
