Multi-species pastures with grasses and legumes have the potential to enhance ruminant nutrition. The nutritive value of two multi-species pastures was evaluated in vivo (standard sheep digestibility measures) during the April to October period, over 5 consecutive years in Normandy. The first multi-species were a mixed sward recommended for use in the Swiss lowlands and the second came from the Loire valley in France. While the nutritive value of both pastures was high on average during the year, the Loire valley mixture had a light advantage in spring and autumn. The high nutritive values observed during autumn reaffirm the nutritional potential of autumn grazing. The results indicate that the prediction of organic matter OM digestibility of multi-species swards using the equation including pepsin-cellulase is imprecise compared to monocultures, but is improved when the age of regrowth is included.
