Resumo: | The objective of this work was to evaluate the effect of extruded soybean and organic selenium supplementation on fatty acid profile and oxidative stability of Holstein milk. Twenty-four Holstein cows were distributed in three blocks and were allocated in three treatments: control diet; diet with 21% extruded soybean; and diet with 21% of extruded soybean + 5 mg of organic selenium. The experiment lasted six weeks. The cows fed with extruded soybean diet produced milk with lower concentration of short and medium chain fatty acids and higher concentration of long chain fatty acids, lower concentration of saturated fatty acids and higher concentration of polyunsaturated fatty acids and conjugated linoleic acid content. The organic selenium supplementation increased milk selenium concentration and delayed milk oxidation. Diet with 21% extruded soybean modified fatty acid profile and resulted in milk susceptible to oxidation. Organic selenium supplementation reduced oxidation and influenced positively the stability of milk. |

Vinte e quatro vacas foram divididas em três blocos e distribuídas ao acaso em três tratamentos: dieta controle; dieta com 21% de soja extrusada e dieta com 21% de soja extrusada + 5 mg de selênio orgânico. O experimento teve duração de seis semanas. As vacas alimentadas com soja extrusada produziram leite com menor concentração de ácidos graxos de cadeias curta e média, maior concentração de ácidos graxos de cadeia longa, menor concentração de ácidos graxos saturados e maior concentração de ácidos graxos poliinsaturados e de ácido linoléico conjugado. A suplementação com selênio aumentou a sua concentração no leite e retardou o processo oxidativo do leite. A dieta com 21% de soja extrusada alterou o perfil de ácidos graxos do leite, aumentando sua susceptibilidade à oxidação; o enriquecimento com selênio minimizou esse efeito e influenciou positivamente a estabilidade do leite.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPaschoal, Juliana JorgeZanetti, Marcus AntonioClaro, Gustavo Ribeiro DelMelo, Mariza Pires dePugine, Silvana PiccoliCunha, José Aparecido2007-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7764Pesquisa Agropecuaria Brasileira; v.42, n.12, dez. 2007; 1793-1799Pesquisa Agropecuária Brasileira; v.42, n.12, dez. 2007; 1793-17991678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAspahttps://seer.sct.embrapa.br/index.php/pab/article/view/7764/4683info:eu-repo/semantics/openAccess2010-10-04T14:12:06Zoai:ojs.seer.sct.embrapa.br:article/7764Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-10-04T14:12:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
