Resumo: | The purpose of this study was to evaluate the effects of docosahexaenoic in the concentrated acid on intake, digestibility, metabolic profile and ingestive behavior of lambs diets. Five crossbred Dorper x Santa Inês lambs with initial age and body weight average of six months and 33 kg, respectively, were used in the trial. The animals were assigned into a 5×5 Latin square design and they received one of the following treatments: 0, 1.5, 3, 4.5 and 6 % of microalgal product (Aurantiochytrium limacinum algae) or ALL-G Rich® in the concentrate. The diets were composed of corn silage and concentrate offered twice daily. During the experimental period, feed, water, feces, blood, and urine were sampled to calculate the intake and digestibility and to characterize the metabolic profile. The ingestive behavior was measured during 24 hours on the last day each experimental period. The time spent on feeding, ruminating and idle activities was measured. Regression analyses were performed considering 5 % of significance. There were no difference on nutrients intake, digestibility, and ingestive behavior with the inclusion of ALL-G Rich® in the diet (p>0.05). There was a significant effect on serum concentrations of cholesterol, low density lipoprotein, alkaline phosphatase and gammaglutamyl transferase, however, all metabolites remained within the range recommended for the animal category. Thus, ALL-G Rich® can be used up to 6% in the concentrate, on dry matter basis, of lambs diet without affect intake, digestibility, metabolic profile, and ingestive behavior. |

Foram utilizadas cinco borregas mestiças (Dorper x Santa Inês) com média de 6 meses de idade e 33 kg. Os animais foram distribuídos em delineamento quadrado latino 5x5 sendo os tratamentos: 0; 1,5; 3,0; 4,5 e 6% de ALL-G Rich® no concentrado. As dietas foram compostas de silagem de milho e concentrado ofertadas duas vezes ao dia. Durante os períodos de avaliação foram mensurados e amostrados os alimento, água, fezes, sangue e urina. A partir dessas amostras foram calculados o consumo e digestibilidade. O comportamento ingestivo foi realizado durante 24 horas no último dia cada período experimental, mensurando o tempo gastos nas atividades de alimentação, ruminação e ócio. Análises de regressão foram utilizadas considerando 5% de significância. Não houve efeito significativo diante do consumo e digestibilidade de matéria seca e dos nutrientes, tal como no comportamento ingestivo com a crescente inclusão de ALL-G Rich® na dieta. Houve efeito significativo para as concentrações séricas de colesterol, lipoproteína de baixa densidade, fosfatase alcalina e gamma glutamil transferase, porém todos os metabolitos mantiveram-se dentre da faixa recomendada para categoria. Portanto, a ALL-G Rich® pode ser utilizada até 6% na matéria seca do concentrado em dietas de cordeiras sem afetar o consumo, digestibilidade, o perfil metabólico e o comportamento ingestivo.Universidade Federal de Minas Gerais2020-08-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/2020310.35699/2447-6218.2020.20203Agrarian Sciences Journal; Vol. 12 (2020); 1-8Caderno de Ciências Agrárias; v. 12 (2020); 1-82447-62181984-6738reponame:Caderno de Ciências Agrárias (Online)instname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGenghttps://periodicos.ufmg.br/index.php/ccaufmg/article/view/20203/19668https://periodicos.ufmg.br/index.php/ccaufmg/article/view/20203/19669Copyright (c) 2020 Caderno de Ciências Agráriashttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAraújo, Maria Júlia Pereira Schultz, Erica Beatriz Jesus, Thauane Ariel Valadares Andrade, Marina Elizabeth BarbosaSousa, Luciana MeloMacedo Júnior, Gilberto de Lima 2022-07-28T16:30:39Zoai:periodicos.ufmg.br:article/20203Revistahttps://periodicos.ufmg.br/index.php/ccaufmgPUBhttps://periodicos.ufmg.br/index.php/ccaufmg/oaiccaufmg@ica.ufmg.br2447-62181984-6738opendoar:2022-07-28T16:30:39Caderno de Ciências Agrárias (Online) - Universidade Federal de Minas Gerais (UFMG)false |
