Resumo: | This study aimed to evaluate the effects of the live yeast and inactive yeast autolyzed on the voluntary intake, digestibility coefficient, efficiency of microbial protein synthesis, characteristics of the ruminal environment - pH, volatile fatty acids (VFA), rumen ammonia nitrogen (RAN), and balance of nitrogen compounds of cattle feed with high concentrate levels. The experiment was carried out from November, 2010 to February, 2011. Five Nellore heifers with 300 kg ± 39.5 of initial body weight and fitted with rumen canullaes, were used and distributed in a 5 x 5 Latin square design, with five treatments, five animals and five experimental periods lasting 15 days. These 15 days were divided in seven days to the animal s adaptation and the other eight days were for the collection of data and materials. Five additives/levels in the same basal diet were evaluated, as follow: negative control (without additives); positive control (1% of the diet dry matter of sodium bicarbonate and magnesium oxide in the proportion of 4:1); live yeast (10 g/day); inactive yeast autolyzed in the doses of 15 and 30 g/day. The experimental diets consisted of two concentrates based on corn and soybean meal, that differed only by the presence or absence of sodium bicarbonate and magnesium oxide, containing 20% of corn silage, dry matter basis, and calculated to weight gain of 1.2 kg per animal per day, second NRC (2000). The use of additives didn t alter (P>0.05) dry matter intake (DM), and intake of organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber corrected for ash and nitrogenous compounds (NDFap), non-fiber carbohydrates (NFC) and total digestible nutrients (TDN). Only the EE digestibility coefficient was influenced (P<0.05) by the treatments, showing higher values to the treatments positive control and inactive yeast autolyzed in the dose of 30 g/day; the negative control was the treatment that presented the lower EE digestibility coefficient; the treatments inactive yeast autolyzed in the dose of 15 g/day and live yeast didn t differ from the others. The digestibility coefficient of DM, OM, CP, NDFap, NFC and the content of TDN were not affected (P>0.05) by the treatments. Effects were not detected (P>0.05) among treatments on the nitrogen intake, fecal nitrogen excretion, urinary excretion of nitrogen, balance of nitrogen compounds, nitrogen utilization efficiency in relation to N intake and to N absorbed and efficiency of microbial protein synthesis. There were no treatments effects (P>0.05) on the ruminal pH average, RAN, total production and molar ratio of VFA and in the ratio acetate:propionate. The evaluated blood metabolites, glucose, creatinin and urea, were not influenced (P>0.05) by the studied additives. |

Live yeast and inactive yeast autolyzed as additives to cattle. 2012. 50 f.

O experimento foi conduzido entre novembro de 2010 e fevereiro de 2011. Foram utilizadas cinco novilhas Nelore, de aproximadamente dois anos de idade, com peso corporal médio inicial de 300 ± 39,4 kg, fistuladas no rúmen, distribuídas em delineamento em quadrado latino 5 x 5, com cinco tratamentos e cinco períodos com 15 dias de duração. Destes 15 dias, sete foram destinados à adaptação dos animais e os oito dias restantes para realização de coletas de dados e material.. Avaliou-se cinco diferentes aditivos/níveis em uma mesma dieta basal: controle negativo (sem aditivos); controle positivo (bicarbonato de sódio e óxido de magnésio na proporção de 4:1 da matéria seca da dieta); levedura viva na dose de 10 g/animal/dia e levedura inativa autolisada nas doses de 15 e 30 g/animal/dia. As dietas experimentais consistiram de dois concentrados à base de milho e farelo de soja, que diferiam entre si somente pela presença ou não de bicarbonato de sódio e óxido de magnésio, contendo 20% de silagem de milho, base da matéria seca e calculada para proporcionar ganho de peso de 1,2 kg/animal/dia, segundo o NRC (2000). O uso de aditivos não alterou (P>0,05) o consumo de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro corrigida para cinzas e proteína (FDNcp), carboidratos não fibrosos (CNF) e nutrientes digestíveis totais (NDT). Somente o coeficiente de digestibilidade (CD) do EE foi influenciado (P<0,05) pelos tratamentos, apresentando maiores valores para os tratamentos controle positivo e levedura autolisada na dose de 30 g/dia; o controle negativo foi o tratamento que apresentou a digestibilidade do EE mais baixa; os tratamentos levedura autolisada na dose de 15 g/dia e levedura viva não diferiram estatisticamente dos anteriores. Os demais CD, CDMS, CDMO, CDPB, CDFDNcp, CDCNF e o teor de NDT não foram afetados (P>0,05) pelos tratamentos. Não foram detectados efeitos (P>0,05) dos tratamentos sobre o consumo de nitrogênio, excreção fecal de nitrogênio, excreção urinária de nitrogênio, balanço de compostos nitrogenados, eficiência de utilização do nitrogênio em relação ao nitrogênio consumido e ao nitrogênio absorvido e eficiência de produção microbiana. Os tratamentos não influenciaram (P>0,05) a média do pH ruminal, a concentração de NAR, a produção total e proporções molares de AGV e a relação acetato:propionato. Os metabólitos sanguíneos avaliados, glicose, creatinina e ureia, não foram influenciados (P>0,05) pelos aditivos estudados.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de ViçosaMestrado em ZootecniaUFVBRGenética e Melhoramento de Animais Domésticos; Nutrição e Alimentação Animal; Pastagens e ForragiculFisiologiaNutriçãoProdução e reprodução de ruminantesPhysiology, NutritionProduction and reproduction of ruminantsCNPQ::CIENCIAS AGRARIAS::ZOOTECNIALevedura viva e levedura inativa autolisada como aditivos para bovinosLive yeast and inactive yeast autolyzed as additives to cattleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf240793https://locus.ufv.br//bitstream/123456789/5743/1/texto%20completo.pdfeeb362298c55405471ae4aeda1bb3acdMD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain84123https://locus.ufv.br//bitstream/123456789/5743/2/texto%20completo.pdf.txt2b1731987cac5528fd6107a87f16086bMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3515https://locus.ufv.br//bitstream/123456789/5743/3/texto%20completo.pdf.jpgb0edacbeffeaf974dc1f09df679e68b5MD53123456789/57432016-04-10 23:13:19.86oai:locus.ufv.br:123456789/5743Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:13:19LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
