Abstract

[EN] Forty eight Churra ewes were used to investigate the influence of four dietary vegetable oils (palm (PO), olive (OO), soybean oil (SO) and linseed oil (LO)) on milk composition and growth of sucking lambs. The percentage of SFA was higher (P<0.001) feeding PO. The proportion of MUFA was higher feeding OO and the proportion of PUFA and rumenic acid were higher (P<0.001) with SO and LO than PO and OO. Concentrations of n-3 fatty acids were higher (P<0.001) feeding LO. Growth of sucking lambs was not affected by treatments studied.

El presente trabajo ha sido financiado por el Instituto Tecnológico Agrario de Castilla y León (Proyecto VA C2 C), la Junta de Castilla y León (Ref. VA058A07) y realizado dentro de un convenio de colaboración entre la Diputación de Palencia y la Universidad de Valladolid.
