FOOD SUPPLEMENT, METHOD FOR INCREASING THE BACTERIAL MASS IN THE RUMEN OF A RUMINANT AND FOOD PREPARATION AND CORRESPONDING USES

摘要

The invention relates to a food supplement, a method for increasing the bacterial mass in the rumen of a ruminant and a food preparation and corresponding uses. The food supplement comprises hydrolysed proteins that have a degree of hydrolysis above 28% and/or contain more than 23 mg of alpha-amino nitrogen per gram of protein and/or contain more than 10% of free amino acids. The hydrolysed proteins are animal proteins, preferably haemoglobin. The supplement is administered orally, included in a food preparation, in liquid, concentrated or dehydrated form. The supplement forms the basis of a method for increasing the bacterial mass in the rumen of a ruminant, in which a supplement containing hydrolysed proteins in accordance with the invention is added to the diet of the ruminant.
