1. Energetic metabolism in fasting sheep: regularization of metabolic profile by treatment with oral glucose, with prior handling of gastric groove
ABSTRACT The objective of this research was to evaluate a possible corrective measure against negative metabolic states, as occurs in the advanced stage of gestation in ewes, and that sometimes produces a disease called pregnancy toxaemia. In the present research, we found that the joint administration of i.v. lysine-vasopressin (0.08 IU/kg body weight, BW)

3. 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,

4. Optimization of ultrasound-assisted extraction of sheep abomasum protein concentrates by response surface methodology and evaluation of their properties
Abstract The aim of this study was to extract sheep abomasum protein concentrates (SAPC) by ultrasound-assisted extraction (UAE) and to investigate the properties of SAPC. Response surface methodology and Box-Behnken design were applied to determine the optimal parameters for UAE. The maximum water-soluble protein concentration was 320.5 mg protein/g dry ra

5. Clinical and pathological aspects of bovine lymphoma affecting the spinal cord
RESUMO: Os aspectos clínicos e patológicos do linfoma bovino afetando a medula espinhal foram avaliados através de um estudo retrospectivo dos protocolos de necropsia durante o período de 2005-2017. De um total de 34 bovinos com linfoma, 24 apresentaram afecção do sistema nervoso central (SNC) restrito a medula espinhal. Todos os bovinos afetados eram

6. Potential and existing mechanisms of enteric methane production in ruminants
Enteric methane (CH4) emissions in ruminants have attracted considerable attention due to their impact on greenhouse gases and the contribution of agricultural practices to global warming. Over the last two decades, a number of approaches have been adopted to mitigate CH4 emissions. However, the mechanisms of methanogenesis have still not been fully defined.

7. Sulfur sources in protein supplements for ruminants
The present study evaluates the efficiency of different sulfur sources for ruminant nutrition. The fiber digestibility and the amino acid profile were analyzed in the duodenal digesta of crossbred steers fed Brachiaria dictyoneurahay. The sources utilized were elemental sulfur (ES70S), elemental sulfur (ES98S); calcium sulfate in hydrated (HCS), CaSO4.2H2O,

8. Perdas na ensilagem e desempenho de bovinos de corte suplementados com dietas contendo silagem de capim-marandu em duas idades de rebrotação tratadas com inoculante bacteriano / Silage losses and performance of beef cattle fed diets with Marandu grass silages at two ages of regrowth treated with bacterial inoculant
Three experiments were carried out to evaluate intake and the partial and total nutrient apparent digestibilities, nitrogen compounds balance, microbial efficiency, rumen traits and the performance of beef cattle fed diets based on Brachiaria brizantha cv Marandu at two ages of regrowth with and without microbial inoculant Sil ALL C4 (Alltech Brazil), as wel

9. Simulation and validation of the ruminal digestion of carbohydrates in cattle from kinetic parameters obtained by in vitro gas production technique
This study aimed to validate the estimates of the ruminal degradation of total carbohydrates (TC), ruminal and total digestion of fibrous carbohydrates (FC) and microbial nitrogen flow in the abomasum evaluated by in vitro gas production technique (IVGP). Six ruminally and abomasally cannulated steers arranged in a double 3 × 3 latin square were used to mea

11. Evaluation of reference genes for real-time PCR studies of Brazilian Somalis sheep infected by gastrointestinal nematodes.
Precise normalization with reference genes is necessary, in order to obtain reliable relative expression data in response to gastrointestinal nematode infection. By using sheep from temperate regions as models, three reference genes, viz., ribosomal protein LO (RPLO), glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and succinate dehydrogenase complex subuni

12. Anthelmintic activity of Lippia sidoides essential oil on sheep gastrointestinal nematodes.
Medicinal plants have been investigated for their anthelmintic properties and shown to be effective against eggs and larvae of gastrointestinal nematodes. The aim of this study was to evaluate the efficacy of the Lippia sidoides essential oil (LsEO) on sheep gastrointestinal nematodes. Initially, 44 naturally infected sheep were divided and treated with 200
