Sažetak
Simmental breed cows although being dominant breed at the family farms in Croatia are not yet sufficiently adapted to the machine milking due to their improper udder index. The aim of this study was to determine the somatic cells count in Simmental cows milk according to the order of lactation and lactation stages. Survey has been conducted at four family farms and a total of 61 cow of Simmental breed from first to third lactation were enrolled in a study. The study results have shown that the maximum somatic cell count is in milk (LSCC=3.59) from the stables with have a downward floor, but not significantly higher in comparison to other ways of keeping the cows. However, the lowest udder hygiene was in the stables where the milking was performing by putting the milk into the cans and where cows were kept on the embroidery. The significant increase in LSCC (P<0.05) was determined in the third lactation in comparison to the second lactation. Given the stage of lactation largest LBSS was found in the second stage, which was significantly higher when compared to the first. Farms with a free way of keeping cows and milking cows in parlours are becoming more and more like a guidelines in current milk production, and animals that reside in those farms have a healthier udders and less micro-organisms in milk.
