ABSTRACT The objective of this study was to examine the physicochemical composition and sensory properties of Boursin cheese made from the milk of goats fed diets with increasing levels of cassava chips replacing corn. Eight lactating Alpine goats were distributed into two 4 × 4 Latin squares, where they were subjected to diets in which 0, 33, 66, and 100% of corn was replaced with cassava chips. The cheeses were prepared with individual milk of each goat for physicochemical, yield, […]

ABSTRACT The objective of this study was to evaluate the effect of different stocking densities and the presence/absence of two artificial substrates on water quality and production rates of marine shrimp in a biofloc shrimp nursery culture. Two experiments were performed: different stocking densities with mosquito netting substrate and the presence/absence of polyester-type substrate. The first experiment lasted 38 days, and shrimp at an initial weight of 0.013±0.010 g were stocked in 24 tanks. The second experiment lasted 35 days, […]

The objective of this investigation was to evaluate the weight and percentage of the non-carcass components and the mineral content (macro minerals and trace minerals), crude protein, ether extract, moisture and vitamin E of the heart, liver, tongue, lungs, reticulum, kidneys and meat from the longissimus dorsi of lambs in feedlot finishing. Thirty-two non-castrated Ile de France male lambs, fed diets containing sunflower seeds and vitamin E from 15 to 32 kg of body weight were allotted in a completely […]

The aim of this work was to select higher yielding and persistent genotypes, evaluating their progenies agronomically. The DM yield of 22 progenies compared with the population of UFRGS-2004-2 and with the Jacuí cultivar of white clover mixed with ryegrass (Lolium multiflorum Lam.), during the years 2008 and 2009 was evaluated. The average DM yield of white clover during the two years was 3671 and 2107 kg/ha, in Eldorado do Sul and Bagé, respectively. In Eldorado do Sul and Bagé […]

This study was carried out with the objective of evaluating the influence of breed groups and sexual conditional on carcass traits of young goats raised in feedlot. It was used 91 animals, 52 males and 39 females, belonging to five breed groups: Alpine, ½Boer + ½Alpine, ½Nubian + ½Alpine, ¾Boer + ¼Alpine and ½ Anglo-Nubian + ¼Boer + ¼Alpine. On the slaughter day, the shrunk weight was measured after 24 hours of solid fasting. Biometric and carcass measures were objectively […]

This research aimed at evaluating ponderal performance of the calves from birth to 189 days of age. Ninety-five calves were used (55 Aberdeen Angus and 40 Hereford), grazing natural pasture. Milk production of cows was estimated by the weight-suckled-weight method, and ponderal performance of the calves was evaluated in 21-day intervals from birth. Calving season was divided at time 1 (September) and time 2 (October). For analyses, it was included in the statistical model as fixed effects, breed of the […]

The present work was aimed to evaluate the effect of mineral protein supplementation with addition of chromium attached to the organic molecule on the productive performance, carcass traits and beef quality in steers finished under grass conditions. For this, 18 Nellore and 18 F1 Brangus × Nellore steers were used, with 16 months of average initial age and slaughtered at 22 months, distributed equally into two treatment of mineral protein supplementation with and without addition of chromium attached to the […]

The objective of this work was to evaluate the effect of three commercial feeds recommended for carnivorous fish on processing yield and fillet composition of surubim (Pseudoplatystoma sp) raised in net cages. The surubim fishes were raised in net cages during one year, when were fed three diets with 43.5, 42.6, and 42.1% crude protein; 6.3, 8.7, and 4.5% ether extract and 5,078, 4,931, and 4,994 kcal of gross energy, respectively. Fishes were allotted to a completely randomized design, with […]

Forty-nine intact Texel lambs were used to evaluate the effects of different birth periods (August vs. November) on body development, body measurements and carcass characteristics. Animals were maintained in pasture and slaughtered in December for those born in August and April for those born in November at 129 and 164 days of age, respectively. Prior to slaughtering forage yield was estimated by the Botanal technique, which showed that animals born in August had access to better quality pasture. These lambs […]

Thirty-two intact lambs averaging 17.1 kg of initial body weight were assigned to one of the following four treatments: 30, 45, 60 or 75% of dietary concentrate in a completely randomized design (eight lambs/treatment). Lambs were feedlot fed during the experimental period (43 days). After slaughter, carcasses were refrigerated for 24 h. It was measured the weights and percentages of five cuts from the half carcass as well as the proportion of muscle, bone and fat tissue from the leg. […]
