The aim of our experiment was to compare the effect of different levels of the addition of Saccharomyces cerevisiae yeast culture on feed carrier to the current ration on the blood parameters of high-pregnant breeding cows and their calves. The experiment included 42 breeding cows of the Czech Fleckvieh cattle breed and their calves. The breeding cows were divided into two age groups, each of 21 heads. The first group included heifers and the second group consisted of cows on the 2nd and higher lactation. Each age group had 7 control animals (Heifers/Cows - control), 7 animals receiving 50 g of yeast culture on the feed carrier per head and day (Heifers/Cows - 50 g), and 7 animals receiving 150 g of yeast culture on the feed carrier per head and day (Heifers/Cows - 150 g). Blood of the animals was sampled three times during the experiment - two times in the cows and one time in their calves. The first blood sample was taken from the breeding cows before the start of feeding the yeast culture ca. 23 days before the expected parturition (Cow -23). The second blood sample was taken from the breeding cows within 24 hours after birth (Cow +2) and the third blood sample was taken from the calves on the 3rd-4th day after birth (Calf +4). Parameters ascertained in the processed serum were: immunoglobulines G (IgG), crude protein (CP), gamma glutamyl-transferase (GGT), urea, glutamate-pyruvate-transaminase (GPT) and glutamate-oxaloacetate-transaminase (GOT).
