This work was realized to evaluate the effect of natural additives as propolis or essential oils addition on animal performance, feed intake, apparent digestibility and carcass characteristics of bulls finished in feedlot. Thirty bulls (½ Aberdeen Angus vs. ½ Nellore) were randomly assigned in one of three diets (control – CON, propolis – PRO and essential oils – OIL) and kept in feedlot (individual pen) during 55 days. CON diet consists of 45% corn silage, 40% concentrate (cracked corn, soybean meal, limestone and mineral salt) and 15% glycerine. The PRO group received same diet that control plus 3 grams to animal day-1 of propolis dry added to the concentrate. The OIL oils group received same diet that control and 3 grams to animal day-1 of essential... |

This study aimed to determine the in vitro degradability of dry matter and the total gas production of oil seed press cake from biodiesel production (Gossypium hirsutum L., Helianthus annuus L., Ricinus communis, Moringa oleífera L. and Pinhão manso curcas L.) at four different levels of replacement (0, 30, 50, and 70%) for cane sugar (Saccharum officinarum RB.) in ruminant feed. Inocula were prepared using the ruminal fluid of three Holstein cows, and data were collected after 48 hours of incubation. The byproducts of Moringa had the highest degradability, and castor presented the lowest values at all evaluated levels of replacement. Castor bean byproduct showed the highest total gas production, cotton showed the lowest production, and the byproduct of... |

ABSTRACT The aim of this study was to assess the magnitude and duration of blood and urine changes and the side effects of hyperchloremic acidosis induced by the intravenous administration of hydrochloric acid in sheep. Five healthy, crossbred adult ewes, with a mean body weight of 44±2.9kg were used. The hydrochloric acid solution was administered intravenously at a rate of 25mL/kg/h for 4 hours continuously. Venous blood and urine samples were collected and pH values, blood carbon dioxide partial pressure, bicarbonate, base excess, strong ion difference, anion gap, total concentration of nonvolatile buffers, creatinine, plasma L-lactate, plasma and urine sodium, potassium, and chloride were determined. The experimental protocol induced severe... |

The objective of this work was to investigate the ingestive behavior of sheep fed with different inclusions of babassu endocarp meal I. The animals receive isofibrous, isoenergetic and isonitrogenous diets containing the by-product in increasing levels of inclusion (zero; 7,5%; 15%; 22,5%). Twenty rams were used in this study and distributed in four treatments with five repetitions each. The ingestive behavior was conducted over a period of 24 hours, with visual observations at 5 minutes intervals and the variables being: idle, ruminating, feeding and chewing. The study demonstrated that the dry matter intake in function of the body weight and the metabolic weight decreased linearly as the babassu endocarp meal I was included in the diet. The feeding,... |

Las nuevas líneas de investigación en nutrición de rumiantes están buscando diseñar productos con liberación prolongada de urea dentro del rumen. El objetivo de esta investigación fue desarrollar y evaluar microcápsulas que liberen urea en el líquido ruminal. Métodos: Las microcápsulas fueron preparadas por el método de emulsión y evaporación de solvente, como primer paso se preparo el acarreador poroso, después se preparo la fase orgánica con Eudragit RS 100 y por último se preparo la fase acuosa en donde fue agregada la fase orgánica. Las microcápsulas se identificaron mediante microscopia electrónica de barrido, determinando el tamaño y la morfología. Se evaluó la encapsulación de la urea, la flotabilidad de las microcápsulas y la liberación de N... |

A silagem é a forragem úmida, ou parcialmente seca, conservada em meio ácido. A ensilagem compreende o armazenamento da forragem em ambiente anaeróbico com o objetivo de restringir a respiração celular, que continua ocorrendo após o corte da forrageira, e fornecer as condições adequadas para o desenvolvimento de bactérias epifíticas, produtoras de ácido lático. Neste processo, os ácidos produzidos pela fermentação de substratos presentes na planta reduzem o pH da massa ensilada, inibindo a ação de enzimas e de microrganismos capazes de promover a sua deterioração. A ensilagem deve visar o aproveitamento da forrageira em seu estádio ótimo de desenvolvimento, conciliando produtividade e valor nutritivo. O seu objetivo é minimizar as perdas de matéria seca... |

The objective of this project is to produce pudu embryos, obtained by means of fibroblast transfer taken from the ear of one animal, to the oocytes of a domestic ruminant such as cattle. In further work, the pudu embryos will be transferred to the uterus of synchronized recipient females of another species. Biopsies 1mm in size were obtained from the outer rim of the ear of two male pudu deer belonging to the Buin Zoological park, Santiago, Chile. The cell lines have been established and kept according to protocols used in cattle. The oocytes are obtained through a puncture in the oocyte-cumulus complex (OCC) from cow ovaries recovered from the butcher. Each oocyte is enucleated and fused with an isolated fibroblast which is inserted beneath the pellucid... |

Abstract: The objective of this work was to assess the nutritive value of four elephant grass (Pennisetum purpureum) genotypes. The chemical composition, intake by sheep, and digestibility of different genotypes (G1, G2, G3, and G4) were evaluated. A dry matter (DM) digestibility assay was performed with total leftovers and feces collected from 20 sheep kept in metabolic cages. G3 had lower DM intake in grams per animal per day compared with G1 and G2, and it had greater digestibility, crude protein, neutral detergent fiber, and acid detergent fiber values. G1, G2, and G4 have the best nutritive values among the evaluated genotypes. |
