ABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutting ages (45 and 60 days) with four replicates per treatment (silos). The parameters of dry matter losses, effluents losses, gas losses, pH, microbial population, and nutritional value of the silage were evaluated. There was no difference in pH among the tested doses of crude glycerin. However, reductions in dry matter and gas losses were observed as a function of crude glycerin doses. Bacterial populations... |

This experiment aimed to determine the influence of diets with inclusion of protected fat and vitamin E on performance, yield and carcass characteristics of feedlot lambs with different weights. Thirty-two non-castrated Santa Ines lambs were fed diets with a ratio of 40% forage and 60% concentrate ad libitum, with presence or absence of protected fat and/or vitamin E, in a total of four diets. Two weights of early containment were also considered: between 20 and 25 kg and between 30 and 35 kg. All animals were slaughtered at 84 days of confinement. Animals fed diets without addition of protected fat, regardless of the use of vitamin E, had the highest intakes of dry matter, crude protein, neutral detergent fiber and ash, and decreased intake of ether... |

The growing global demand for meat and particularly in countries such as Brazil is expected to increase intensive animal production. Consequently the main pollutants of interest are nitrogen (N), phosphorus (P) and greenhouse gases (GHG). Nitrogen can be a problem through nitrate leaching to water bodies, ammonia, and nitrous oxide emissions to air. Phosphorus loading in soil from manure application can be the main issue due to the tendency of P to accumulate in soil and leach to groundwater and rivers. The sources of agricultural GHG emissions include methane from enteric fermentation, manure storage and spreading, and nitrous oxide mainly from application of manure on land. Dietary manipulation has proven to be an effective tool to reduce... |

The objective of this study was to determine the best level of oil licuri concentrate on dairy cows. The best level was determined through an analysis of the milk's chemical composition and fatty acid profile. Sixteen lactating cows from the Holstein × Zebu cross breed kept on Tanzania grass pastures were divided into four 4 × 4 Latin squares, which were formed by four experimental periods of 21 days. The 21-day experimental periods were divided into 17 days for adaptation and four days for collection. Cows received three kg of concentrate per day, at the time of milking. Treatments consisted of four types of feed containing the following levels: 0, 1.5, 3.0, and 4.5% inclusion of dry matter (DM) licuri oil concentrate. The licuri oil levels changed the... |

The aim of this study was to report and morphologically describe two small intestinal nematode genera present in cattle and sheep from Tabasco, Mexico. The specimens studied were obtained from animals for slaughter on a trail, cleared in Amann's lactophenol and their measurements were recorded using a calibrated ocular micrometer. Based on their morphologic characteristics, three species were identified: Cooperia curticei, Cooperia punctata and Trichostrongylus colubriformis. In C. curticei, the length of the tail-vulva was higher (1726.9± 194.4 mm) than in C. punctata (1422.1±151.7 mm); and the vulva shape of C. curticei was flat, while in C. punctata, it was botonous. In Cooperia males, the spicule lengths were similar in both species (139±13 mm). The... |

Nowadays consumers are highly interested in the quality of the products they eat, especially when this refers to meat. Consumption of meat from ruminant animals and its derivatives is on the increase, particularly in some countries such as Brazil, one of the main beef exporters in the world. Current analysis is a review of the different factors that affect meat quality in ruminants, with a focus on sensory analyses. Some factors throughout the entire meat chain are analyzed, or rather, from those that producers underscore to improve the quality of their products to those related with consumers' habits and beliefs. Most of the papers reviewed have been developed by researchers involved in the Meat Quality and Technology Group (University of Zaragoza and... |

Foram avaliados os efeitos do emurchecimento e da inclusão de raízes (0, 15, 30 e 45% da matéria natural) sobre a composição químico-bromatológica e parâmetros fermentativos de silagens da parte aérea da mandioca. O emurchecimento influenciou significativamente o teor matéria seca (MS), a densidade e o pH das silagens em todas as doses de adição de raízes. A inclusão destas elevou o teor de MS em 0,128 e 0,261%, a densidade em 1,79 e 4,54 kg m-3 e, reduziu o pH em 0,0007 e 0,0062, respectivamente nas silagens emurchecidas ou não, a cada unidade percentual de adição de raízes. A exceção dos teores de fibra detergente ácida (FDA) e lignina, todos os demais parâmetros apresentaram interação significativa entre o emurchecimento e a inclusão de raízes. O... |
