Four male, castrated, undefined, rumen fistulated sheep were used, with a mean live weight of 49,1 kg in a 4 x 4 Latin square experimental design, with treatments being included of 2, 4 and 6 g/animal/day of functional oils and the control treatment without the addition of the oil. After 21 days for adaptation of the animals, the experiment was conducted in four periods of 20 days, 15 for adaptation to diet and five for collection of samples and data. The apparent digestibility of dietary components and ruminal parameters: ammonia, total sugars, peptides and amino acids were not influenced by the treatments. The pH had a cubic effect with higher values observed with supplementation of 4,7 g/day and the lowest value with 1,4g/day of functional oils. Throughout the day, the concentration of sugars presented quadratic effect increasing in the first hours after the feeding. There was a linear effect over time for the concentrations of peptides in the ruminal fluid of sheep receiving 2g/day of functional oils, for amino acid concentrations in sheep not supplemented with functional oils and for ammonia, in this same treatment with a variation of 9,85mg/dL to 25,29mg/dL. In the same way, the ruminal pH also varied as a function of time in a linear way after feeding for all levels of supplementation, with increase in the two hours after feeding, followed by decreasing for at least 6 hours, and evidencing a lower pH value of 5,78. No changes were observed in nitrogen consumption and nitrogen balance, with mean values of nitrogen retained of 24,5g/day, corresponding to 65,07% of the ingested nitrogen. Excreted purine derivatives corresponded to the proportion of 51% allantoin and 48% uric acid, xanthine and hypoxanthine and did not show changes in microbial synthesis. CAPES Objetivou-se avaliar o efeito da inclusão de diferentes níveis de óleos funcionais extraídos da mamona (Ricinus communis L.) e da casca da castanha do caju (Anacardium occidentale L.) sobre consumo e digestibilidade de nutrientes, parâmetros ruminais e síntese de proteína microbiana em ovinos. Foram utilizados quatro ovinos machos, castrados, sem raça definida, fistulados no rúmen, com peso vivo médio de 49,1 kg em um delineamento experimental quadrado latino 4 x 4, sendo os tratamentos a inclusão de 2, 4 e 6 g/animal/dia de óleos funcionais e o tratamento testemunha sem a inclusão do óleo. Após 21 dias para adaptação dos animais, o experimento foi conduzido em quatro períodos de 20 dias, sendo 15 para adaptação a dieta e cinco para coletas de amostras e dados. A digestibilidade aparente dos componentes da dieta, e os parâmetros ruminais: amônia, açúcares totais, peptídeos e aminoácidos não foram influenciados pelos tratamentos. O pH apresentou efeito cúbico com maiores valores observados com suplementação de 4,7g/dia e o menor valor com 1,4 g/dia de óleos funcionais. Ao longo do dia, a concentração de açúcares apresentou efeito quadrático aumentando nas primeiras horas após a alimentação. Houve efeito linear ao longo do tempo para as concentrações de peptídeos no fluido ruminal de ovinos recebendo 2g/dia de óleos funcionais, para as concentrações de aminoácidos nos ovinos não suplementados com óleos funcionais e para amônia, neste mesmo tratamento com variação de 9,85 mg/dL à 25,29mg/dL. Da mesma forma, o pH ruminal também variou em função do tempo de forma linear após alimentação para todos níveis de suplementação, com aumento nas duas horas após arraçoamento seguindo de decréscimo por pelo menos 6 horas, e evidenciando menor valor de pH de 5,78. Não foi verificado alterações no consumo e balanço de nitrogênio, com valores médios de nitrogênio retido de 24,5 g/dia, correspondendo a 65,07% do nitrogênio ingerido. Os derivados de purina excretados corresponderam a proporção de 51% de alantoína e 48% de ácido úrico, xantina e hipoxantina e não evidenciaram alterações na síntese microbiana. 2017-12-21T14:07:15Z 2017-12-21T14:07:15Z 2017-02-23 masterThesis MICHAILOFF, Andressa Alaine.
