Extract

In north-west of Spain dairy sheep are fed high amounts of concentrate, which are usually offered at milking time. This pattern of feeding often affects negatively the rumen fermentation (Mould et al., 1983). One alternative to reduce these negative effects could be the use of complete diets. The objective of this study was to obtain information on rumen fermentation in sheep receiving complete diets with different forage:concentrate ratio.
