MADALENA LIMA MENEZES PARÂMETROS PLASMÁTICOS DE EQUINOS ALIMENTADOS COM NÍVEISAos amigos, que sempre estiveram ao meu lado na alegria e na tristeza e que nunca me abandonaram.As meninas do Jambalaya, obrigada por tornarem essa jornada mais leve e por terem me recebido de braços abertos, desejo tudo de melhor a vocês e que tenham muito sucesso nos caminhos que escolherem percorrer.A Capes pela bolsa concedida na realização do Mestrado.À FZEA por tornar possível a realização desse trabalho por meio da estrutura e de seus funcionários.A todos que de alguma maneira contribuiu com a elaboração, execução e finalização desse trabalho, Obrigada a todos!!! The present study aimed to evaluate the effect of levels of citrus pulp on blood parameters of horses tied to energy metabolism of horses. Five animals were used,with an average age of 3,5 years and body weight of 460,6 ± 76,86 kg mongrel, hand fed twice daily at 7:00 and 16:00. Diets were formulated to meet the demand of animals in maintenance, 60% of energy from the forage and 40% concentrate, containing increasing levels of citrus pulp (0, 7, 14, 21 and 28%). Blood collection occurred at times: before eating, one, three, six, nine hours after feeding. Blood samples were collected via jugular venipuncture using vacuum collectors for the determination of albumin, triglycerides, cholesterol, glucose, insulin and short-chain fatty acids tubes. The area under the curve and the peak glucose and insulin, for which no effect (P>0,05) were observed, were calculated. There was no effect (P> 0,05) of diet on blood concentrations of parameters. There was no effect (P>0.05 ) and time of collection on the variables: short-chain fatty, cholesterol, triglycerides and albumin acids, but effect ( p < 0.05 ) was observed for glucose concentrations (y = -0.521x² + 4.133 x 84.647) and insulin (y = -0.097x ² + 0.795 + 1.616 x). The citrus pulp is a promising ingredient in feed for horses without causing changes in blood concentrations of glucose, insulin, cholesterol, triglycerides and short-chain fatty acids. Diets with high fiber inclusion and participation of ingredients with easily fermentable fibers are beneficial because the diets of horses keeps the glucose and insulin curves near the baseline plus delay the postprandial glycemic fall.
