Profile of milk fatty acids from moxotĂł goats fed with different levels of manicoba (Manihot Glaziovii Muel Arg.) silage
The objective of this work was to evaluate the effects of the manicoba silage use (Manihot glaziovii Muel Arg.) in different roughage:concentrate ratios (30:70; 40:60; 50:50 and 60:40 %) on the fatty acids profile of the milk from MoxotĂł goats. Eight multiparous goats with approximately 60 post-birth days and weigh 44 kg on average were used in a Double Latin Square with four treatments, four periods and four animals. Each period lasted 15 days with 10 days of adaptation to experimental diets and 5 days of milk collection. The results of the fatty acids analyses were submitted to the analysis of variance (ANOVA) and regression. An increasing linear effect for the miristic acid (C14:0) and decreasing for the linoleic acid (C18:3) was observed in function of the silage levels in diet. The milk fat presented high contents of desirable fatty acids (C18:0 + unsaturated acids), considered as nutritionally important due to their benefits to the human health. It could be concluded that the manicoba silage could be included in the diet with the participation of up to 60%, presenting a nutrient supply of high nutritional value.<br>O objetivo deste trabalho foi avaliar os efeitos da utilização de silagem de maniçoba (Manihot glaziovii Muel Arg.) em diferentes relaçÔes volumoso:concentrado (30:70; 40:60; 50:50 e 60:40 %) no perfil de ĂĄcidos graxos do leite de cabras da raça MoxotĂł. Foram utilizadas oito cabras multĂparas com aproximadamente 60 dias pĂłs-parto, pesando em mĂ©dia 44 kg, em um Quadrado Latino duplo 4 x 4, com quatro tratamentos, quatro perĂodos e quatro animais. Cada perĂodo teve duração de 15 dias, com 10 de adaptação Ă s dietas experimentais e cinco dias de colheita de leite. Foi verificado efeito linear crescente do ĂĄcido mirĂstico (C14:0) e decrescente para o ĂĄcido linolĂȘnico (C18:3), em função dos nĂveis de silagem da dieta. A gordura do leite apresentou elevado teor de ĂĄcidos graxos desejĂĄveis (C18:0 + insaturados), considerados importantes nutricionalmente pelos seus benefĂcios Ă saĂșde humana
