Gyógynövényes premix hatásának vizsgálata tejelőtehénállományban

Abstract

In this experiment a mix of seven selected herbs was used as a dietary supplement for Holstein Friesian dairy cows. Milk yield, milk protein and milk fat contents were examined by use of 72 cows being in their second or more lactation. Dietary herb supplement significantly enhanced the milk yield in the first phase of lactation and reduced the drop of milk production in the second phase of lactation. Milk protein and milk fat were not influenced by the treatment. According to our results the dietary herb supplementation may be advantageous mostly in the first period of lactation.
