There is increasing pressure to identify natural feed additives mitigate methane emissions from livestock systems. Our objective was investigate the effects of essential oils (EO) extracts star anise (
Animal feeding behavior and diet composition determine rumen fermentation responses its microbial characteristics. This study aimed to evaluate the kinetics of domestic ruminants diets with or without condensed tannins (CT). Holstein dairy cows, Nelore beef cattle, Mediterranean water buffalo, Santa Inês sheep Saanen goats were used as inoculum donors (three animals each species). The substrates maize silage (Zea mays), fresh elephant grass (Pennisetum purpureum), Tifton-85 hay (Cynodon...
Context Methane from ruminant livestock systems contributes to the greenhouse effect on environment, which justifies adoption of novel feed strategies that mitigate enteric emissions. Aims We investigated effects condensed tannin (CT)-rich legumes Flemingia macrophylla, Leucaena leucocephala, Stylosanthes guianensis, Gliricidia sepium, Cratylia argentea, Cajanus cajan, Desmodium ovalifolium, Macrotyloma axillare, paniculatum and Lespedeza procumbens in vitro methane emissions rumen...
Canine obesity, characterized by the excessive accumulation of adipose tissue, is one most prevalent nutritional disorders encountered in veterinary practice. This comprehensive review synthesizes current knowledge on predisposing factors and methodologies for assessing body condition dogs. The discussion encompasses genetic, breed-specific, age-related, lifestyle, dietary, hormonal, owner-related influences contributing to obesity. Key methods condition, including Body Mass Index (CBMI),...

Condensed tannins (CTs) are plant anti-herbivore compounds with antimicrobial activity that can be used in ruminant diets as ruminal microbiome manipulators. However, not all CTs from fodder legumes bioactive due to their wide structural diversity. The aim of our study was investigate the effect 10 CT-containing plants (Flemingia macrophylla, Leucaena leucocephala, Stylosanthes guianensis, Gliricidia sepium, Cratylia argentea, Cajanus cajan, Desmodium ovalifolium, Macrotiloma axilare, D....
Context Alternative feed sources have been investigated as replacements for green forages and cereal grains traditionally used in ruminant feed. We hypothesised that, when replacing of true protein with non-protein nitrogen (NPN) the diet, efficiency utilisation NPN may be affected by source energy that different resources alternatives to maize improve maximise ruminal fermentation characteristics. Aims The objective this study was evaluate effects diets containing carbohydrate associated...
We evaluated the effects of inclusion copaíba (Copaifera officinalis L.) essential oil at 0.05 and 0.1% as a possible replacement synthetic additive butylated hydroxytoluene (BHT) in sheep burgers during 14 days storage refrigerated display case (4°C). During shelf life days, analyzes antioxidant activity, lipid oxidation, pH, color, cooking loss, texture consumer acceptability were carried out on burgers. The addition showed an effect (P > 0.05), reducing oxidation. Copaiba added 0.05%...
Context Plant bioactive compounds such as condensed tannins (CT) are seen an alternative to rumen chemical modulators mitigate methanogenesis in livestock; however, the presence of CT ruminant faeces also produces a series changes soil microbiomes. Little is known about these effects on nutrient dynamics. Therefore, whether affect decomposition process faecal organic matter, delaying it and consequently increasing carbon nitrogen (N) sequestration, merits study. Aims Our study investigated...
O objetivo do artigo foi mensurar os fatores de risco referentes ao manejo sanitário e a produção entre cabras leiteiras sob sistema orgânico convencional. Dois grupos experimentais (orgânico convencional) foram conduzidos simultaneamente. desenho estudo o inteiramente casualizado. rebanho consistiu 25 15 cabritos convencional por 40 20 cabritos. Os parâmetros produtivos sanitários monitorados janeiro 2007 dezembro 2009. No convencional, houve uma taxa aborto 5% (2/40), enquanto que no...
Sustainable production is a principle in which we must meet the needs of present without compromising capacity future generations. Despite successful development pesticides against endo and ectoparasites found domestic ruminants, these parasites are still major problem herbivore system. The purpose this study was to know population gastrintestinal their influence on weight gain calves kept organic conventional grazing. Thus, were randomly selected 2008 2009. fecal egg count (FEC) indentified...

Objetivou-se avaliar a produção de leite e contagem células somáticas coletadas em rebanhos vacas Holandesas lactação, caracterizar os agentes causadores mastite. Foram avaliadas 1760 criadas quatro propriedades localizadas nos estados Minas Gerais, São Paulo Paraná. Foi calculada estatística descritiva para as características analisadas, somáticas, relação às leiteiras diferentes ordens parto. Além disso, foram estimadas correlações entre duas prevalência dos patogênicos da A média foi...
Essential oils (EOs), as rumen additives, decreased CH4 emissions in vitro trials but results from vivo studies are still limited. We investigated the effects of Origanum vulgare (OEO) and Thymus vulgaris (TEO) EOs on methane Nellore beef cattle. Six adult rumen-cannulated cattle were used a double 3 × Latin square design. Treatments consisted three diets containing either mL OEO per kg concentrate, TEO/kg or no EO addition. The experimental period 21 d feeding periods production was...
