[Low-fat milk syndrome]. / Sledování "syndromu snízené tucnosti mléka".

Three groups of cows--one group given linseed supplement, the second split rations of concentrates and the third as control--were studied for five months to investigate the biochemical parameters of rumen fluid and blood serum in animals with the "low-fat milk syndrome". The lowest decrease of butterfat content was observed in the linseed-supplement group of cows. In this group the lowest drop of acetic acid in rumen was found out, along with an increase in adipose metabolites in blood serum--total lipids, triglycerides and cholesterol. There were no variations of the content of glucose and total protein in blood. It has been stated that a linseed supplement can have a positive influence on the "low-fat milk syndrome".
