1. Spontaneous and experimental poisoning by Merremia macrocalyx (Convolvulaceae) in cattle
RESUMO: O objetivo deste trabalho é descrever os aspectos epidemiológicos, clínicos e patológicos da intoxicação espontânea por Merremia macrocalyx em bovinos de Pernambuco, nordeste do Brasil e reproduzir experimentalmente a intoxicação por esta planta. Para determinar a ocorrência das intoxicações, foram visitadas 30 propriedades em seis munic�

2. Carcass characteristics and fatty acid profile of Santa Inês lamb fed banana leftovers
ABSTRACT: The use of new feed resources, particularly local agroindustrial byproducts, such as banana, may be an option for replacing those traditionally used for sheep feed to reduce production costs. Thus, the aim of this study was to evaluate the dietary effects of replacing corn bran with banana leftovers on performance, carcass, non-carcass components,

3. Spontaneous poisoning by Ricinus communis leaves (Euphorbiaceae) in goats
RESUMO: O objetivo deste estudo foi relatar os aspectos clínicos e patológicos de um surto de intoxicação pelas folhas de Ricinus communis em um rebanho de caprinos em Pernambuco, Nordeste do Brasil. Três a cinco horas após a ingestão dos brotos e arbustos jovens da planta, vinte cabras da raça Toggenburg e dois machos mestiços apresentaram quadro c

4. Physiological adaptations of ruminants and their potential relevance for production systems
ABSTRACT Herbivores face the dilemma that the level of feed intake is negatively related to factors that determine digestive efficiency, such as thoroughness of ingesta comminution by chewing, and retention of digesta in the digestive tract. Ruminants have evolved particular adaptations to solve this dilemma. Most ruminants share the characteristic of “dig

5. Replacement of wheat bran with spineless cactus in sugarcane-based diets for steers
ABSTRACT The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (1/2 Holstein-Zebu) were fitted with cannulas in the rumen and then assigned

6. Performance of calves submitted to protocols using extruded or ground starter
Feed processing can affect rumen development in new born calves, and potentially define animal performance. Two feed management systems, extruded starter (Ruter) with possible early weaning and ground starter (control), were evaluated in thirty-two Holstein calves (16 females and 16 males). Animals were randomly assigned to the treatments using a randomized

7. QUALIDADE DA CARCAÇA E CARNE DE NOVILHOS ALIMENTADOS COM DIETAS COM BORRA DE SOJA / CARCASS AND MEAT QUALITY OF STEERS FED DIETS WITH SOYBEAN SOAPSTOCK
The objective of this study was to evaluate carcass characteristics, the non carcass components, the lipid profile and the sensorial characteristics of meat from steers finished in feedlot fed diets containing different levels of inclusion of soybean soapstock. We used 30 Nellore and Charolais-Nellore crossbred steers with initial mean age of 20 months and i

8. FONTES DE CARBOIDRATOS PARA TERMINAÇÃO DE BOVINOS DE CORTE: DESEMPENHO E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / SOURCES OF CARBOHYDRATES FOR STEERS FINISHING: PERFORMANCE AND CARCASS CHARACTERISTICS AND MEAT
The objective of this study was to evaluate the effect of three carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance, carcass characteristics and meat and the components are not part of the carcass of steers finished on confinement. We used 24 steers, crossbred Charolais x Nellore, with initial age of 22 months of initial body

9. Rumen fermentation and nutrient flow to the omasum in Holstein cows fed extruded canola seeds treated with or without lignosulfonate
Four multiparous Holstein cows averaging 548 kg of body weight and 74 d in lactation were used in a Latin square design with four 21-d experimental periods to determine effects of feeding extruded versus non-extruded canola seed, with or without 50 g/kg lignosulfonate on rumen fermentation, nutrient flow to the omasum, and degradability of dry matter (DM) an

10. Editorial
Diets formulated with protein sources presenting different resistance to ruminal degradation were compared by evaluating ruminal parameters, production and microbial efficiency and nutrients flow to the omasum in goats. Eight rumen cannulated non-lactating, non-pregnant goats were distributed in a 4 × 4 Latin square design with two replicates. Treatments co

11. âAvaliaÃÃo morfolÃgica do abomaso e ceco-cÃlon de bovinosâ / Morphologic evaluation of abomasum and cecum-colon of bovines
The morphophysiology related to volatile fatty acids (VFA) absorption throughout the gastrointestinal tract of ruminants is not totally characterized. The elucidation of VFA behavior in all production and absorption sites can contribute to the adoption of nutritional strategies aiming to maximize food utilization and to reduce the occurrence of digestive dis

12. AVALIAÇÃO DE DIFERENTES SISTEMAS DE ALIMENTAÇÃO SOBRE AS CARACTERÍSTICAS QUE AFETAM A QUALIDADE DA CARCAÇA E DA CARNE / EVALUATION OF DIFFERENT FEEDING SYSTEM ON THE CHARACTERISTICS THAT AFFECT THE CARCASS AND MEAT QUALITY
This work was divided in two experiments. In first the objective was to evaluate the carcass, meat, carcass no integrants components and fatty acids profile of intramuscular fat of Devon steers finished in: feedlot (CONF), or winter pasture (pasture of ryegrass - Lolium multiflorum Lam -PTEM), or tropical pasture (association of millet pasture - Pennisetum a
