Resumo: | This study aimed to evaluate the effects of lipid sources with different degrees of fatty acid saturation on the intake, digestibility, nitrogen balance, nutrient flow, microbial production and efficiency, ruminal characteristics, fatty acid (FA) profile in omasal digesta (flow), and ruminal biohydrogenation. Eight rumen fistulated goats that were neither pregnant nor lactating, distributed in a double 4 x 4 Latin square design, were used. Four diets were used, one of them was the control diet (CD) and the other tree were supplemented with different sources of lipids: soy oil (SO), palm kernel oil (PKO), canola oil (CO). Supplementation with 2.3% of oil in dry matter (DM) of total diet did not influence the intakes of DM, energy and nutrients, except the ethereal extract (EE), with higher intake effects for the supplemented diets. The total apparent digestibility of dry matter and nutrients did not show any effects due to the different oil sources, although CO had shown a reduction in the ruminal digestibility of DM, organic matter (OM), neutral detergent fiber (NDF), crude protein (CP), EE and total carbohydrates (TC). Nitrogen balance efficiency was not higher by using the lipid sources. DM and nutrient flow differed among the evaluated diets. The highest flow of all studied variables (g.d-1) was found when CO was used, being similar only to PKO values for NDF and TC. Reduced values for ammoniacal nitrogen concentration were found when PKO was used. It was not found variations among the diets for pH evaluation and transit kinetics. When the lipid profile of omasum was performed, high percentages of vaccenic acid (C18:1 tans- 11) was found for the diet supplemented with SO. Such diet also showed a better efficiency on the conversion of some FA s into C18:1 trans-11 in the rumen. Soy oil may be used as a supplement on dairy goat diet, associated with the ruminal pH reduction by using higher rates of concentrate in relation to the forage on the diet, as a strategy to increase excretion of conjugated linoleic acid (CLA) in milk without compromising nutrient digestibility, microbial efficiency and conditions of the ruminal environment. |

Utilizou-se 8 cabras fistuladas no rúmen, não-gestantes e não-lactantes, distribuídas em um delineamento em quadrado latino 4 x 4, duplicado. Foram utilizadas 4 dietas, sendo uma dieta controle (DC) e três suplementadas com diferentes fontes de lipídios: óleo de soja (OS), óleo de palmiste (OP), óleo de canola (OC). A suplementação com óleo em 2,3% na MS da dieta total não influenciou o consumo de matéria seca (MS), de energia e nutrientes, exceto de extrato etéreo (EE), com maior consumo para as suplementadas. A digestibilidade aparente total da MS e nutrientes não sofreram efeito das diferentes fontes, embora o tratamento com óleo de canola tenha promovido redução na digestibilidade ruminal da MS, da matéria orgânica (MO), da fibra em detergente neutro (FDN), da proteína bruta (PB), do EE e dos caboidratos totais (CT). O balanço de nitrogênio foi mais eficiente sem a inclusão das fontes lipídicas. Os fluxos de MS e de nutrientes, diferiram entre as rações avaliadas, sendo que o maior fluxo de todas essas variáveis (g.d-1) foi observado quando utilizada a dieta óleo de canola, assemelhando-se apenas com a óleo de palmiste nos valores de FDN e CT. Valores reduzidos para a concentração de nitrogênio amoniacal foram obtidos com o uso da ração OP. Na avaliação do pH e da cinética de trânsito não foram verificados variações entre dietas. No omaso, foi observado elevados teores de ácido trans-vacênico (C18:1 tans-11) quando utilizado a dieta OS. Na análise de eficiência de conversão de alguns AGs em C18:1 trans-11 no rúmen, verificou-se que a dieta OS também apresentou superioridade em relação às demais, sugerindo maior produção de ácido linoléico conjugado (CLA). Conclui-se que o óleo de soja pode ser suplementado na dieta de cabras leiteiras, associado à redução do pH ruminal, com o uso de maior proporção de concentrado na dieta, como estratégia para aumentar a excreção de CLA no leite, sem comprometer a digestibilidade dos nutrientes, a eficiencia microbiana e as condições do meio ruminal.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em ZootecniaUFVBRGenética e Melhoramento de Animais Domésticos; Nutrição e Alimentação Animal; Pastagens e ForragiculCaprinosLipídiosBiohidrogenaçãoCaprinesLipidsBiohydrogenationCNPQ::CIENCIAS AGRARIAS::ZOOTECNIA::NUTRICAO E ALIMENTACAO ANIMALPerfil de ácidos graxos e cinética da digestão de nutrientes em caprinosPofile of fat acids and digestion kinetic of nutritious in caprinesinfo: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/pdf621378https://locus.ufv.br//bitstream/123456789/5592/1/texto%20completo.pdf21392034a1465e351e40062319308703MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain272650https://locus.ufv.br//bitstream/123456789/5592/2/texto%20completo.pdf.txt2712130aa25f2dfc6d928ce90d2bced6MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3545https://locus.ufv.br//bitstream/123456789/5592/3/texto%20completo.pdf.jpg26e670a0e511cb602abd2f1c28427ff1MD53123456789/55922016-04-11 23:12:20.314oai:locus.ufv.br:123456789/5592Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-12T02:12:20LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
