An experiment was conducted to estimate the parameters of the Gompertz, Brody, Logistic, and Von Bertalanffy equations through Bayesian inference and evaluate the potential for growth in terms of weight and body composition of laying female quail (Coturnix coturnix japonica). The weights and body compositions of the birds were obtained weekly (1-119 days), allowing the adjustment of the four equations by Bayesian inference. The parameters mature weight (β1), integration constant (β2), maturity rate (β3), and their credibility intervals in four […]

The experiment was carried out to evaluate the effects of continuous ingestion of pectin on intestinal viscosity, intestinal transit time, excreta moisture content, nutrient digestibility and energy metabolism of broilers at starter and growth phases. We used 240 one-day-old Cobb male broiler chicks, distributed in a completely randomized experimental design. Treatments consisted of four concentrations of pectin (0, 10, 30 and 50 g kg-1) with six replicates of 10 birds each. The ingestion of pectin supplied in the feed by […]

In this experiment the chlorophyll and carbohydrate contents of Arachis pintoi were evaluated to verify if the presence of nitrogen in the soil could contribute to the effectiveness of the establishment of this legume. The design was completely randomized, in a 4 × 4 factorial arrangement, with four N rates (0, 40, 80 and 120 kg ha-1) and four irrigation levels (25, 50, 75 and 100% of field capacity), with four replications. The biochemical evaluations of chlorophylls a and b […]

Worldwide interest in small ruminants has increased in recent years in both, the productive and scientific aspects. In Brazil, the same trend has been observed, however, among all small ruminants, goats and sheep can be highlighted. Thus, this review aimed to discuss scientific progress in goat and sheep in the last decade. Data were collected in different databases, such as Institute for Scientific Information (ISI), Scientific Electronic Library Online – SciELO, Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – […]

This study was conducted using 103 male and female lambs from the following genetic groups: Santa Inês (SS) purebred and Santa Inês × Texel (TS), Santa Inês × Ile de France (FS), and Santa Inês × Bergamacia (BS) crossbred. The animals were slaughtered at the following body weights: 15, 25, 35 or 45 kg. After slaughter and cooling of the carcasses, the following cuts were made: neck, rib/flank, short ribs, loin, blade, and hind limb. The composition in muscle, bone […]

This study was conducted using 103 male and female lambs from the following genetic groups: purebred Santa Inês (SS) and crossbreds of Santa Inês x Texel (TS), Santa Inês x Ile de France (FS), and Santa Inês x Bergamacia (BS). Animals were slaughtered at one of the following body weights: 15, 25, 35 or 45 kg. After slaughter and cooling of the carcasses, the following cuts were made: neck, rib/flank, short ribs, loin, blade, and hindlimb. The alometric growth of […]

Carcass yield and growth of organs and innards of 40 crossbreed F1 Holstein X Gir calves fed different liquid diets (whole milk or fermented colostrum-based diets), supplemented or not with soy oil (45 mL) and with or without growth promoter Zeranol were evaluated. The animals were daily fed a diet with concentrate (23% crude protein), Tifton hay ad libitum and 3 L of milk or fermented colostrum. The animals were slaughtered at average weight of 57.38 kg and 60 days […]

The objective of this experiment was to study the effects of feeding whole goat milk or fermented cow colostrum supplemented or not with soy oil and with or without the growth promoter Zeranol on performance of kid goats. Twenty-four Alpine kid goats assigned to a completely randomized design in a 3 x 2 factorial arrangement were used in this trial. The following variables were investigated: weight gain, intakes of dry matter and concentrate, feed conversion, and organ sizes. Significant differences […]

Two experiments were carried out to evaluate the nutritional utilization of soybean hulls for growing horses. In the digestibility assay, four colts, averaging 11 months of age and 350±26kg, were used to determine the nutritional value of diets with soybean hulls. The experimental design was square latine (4 x 4). Four diets were used, one as a reference and three as test diets, where the soybean hulls replaced 33.3, 66.6 and 100% of the Tifton 85 hay of the reference […]

This study offers information on the morphology (in live and in carcass), commercial characteristics, components of the liveweight, quality of the carcass and meat in no castrated lambs derived from the crossing between Border Leicester rams and Corriedale and Polwarth ewes, grazing on native pasture in Rio Grande do Sul, Brazil. Twenty-four lambs slaughtered at 6.5 months of age were used, from which 11 were from Border Leicester rams x Corriedale ewes and 13 were from Border Leicester rams x […]
