| Description | The objective of the present work was to evaluate the physical-chemical characteristics (density, pH, acidity, fat, protein, lactose and total of solids contents) and milk fatty acids composition (C: 4 to C: 20) in response to roughage sources (alfalfa hay T1; oat hay T2 and maize silage T3). Nine Saanen lactating goats were used, in a triple Youden square design (3 animals x 2 periods). There was no treatment effects in the physical-chemical variables in the univariate analyses; by multivariate analyses three distinct patterns of fatty acids could be defined: milk with greater quantity of short chain fatty acids and acids C17:1omega7 e C18:2omega6 (T1); milk with equivalent amounts of short, medium and long chain fatty acids (T2); and milk with greater amounts of acids C16:1omega7, C17:0, C18:1omega9 and C20:0 (T3). These results indicated that the roughage sources used in the diet of lactating dairy goats affected the fatty acids composition, without altering the milk physical-chemical characteristics. The acids more sensitive to the treatment effects were: C10:0, C12:0, C14:0, C16:0, C16:1omega7, C18:0 and C18:3omega6. |
