EXPERIMENT ON PROTEIC SUPPLEMENTATION SUBSTITUTION BY AUTOLYZED BEER YEAST IN HOLSTEIN-FRISIAN RACE FEEDING
Abstract
The purpose of this paper is to demonstrate how the protein supplementation in Holstein-Frisian cows could be substituted by autolyzed beer yeast, a by-product of beer brewing. Beer yeast is rich in aminoacids, vitamin and minerals. The beer yeast was given to the cows for six weeks, but no modification in the production of milk occurred during that period.
