Influence of environment and climate factors and temperature is very important in dairy production. It is reflected in cow health status, increased subclinical and clinical mastitis rates, as well as cow and calf mortality when sudden temperature arising are present. These facts are very important, causing poor milk quality followed by somatic cell count arise and less profit. During summer months, there were notice 14 cases of respiratory diseases among calves and increased subclinical and clinical mastitis rate on dairy farm populated with 450 dairy cows when weather changed. Thirty two of 170 cows in puerperium revealed subclinical and paremchymatose forms of mastitis, 24 and 8 respectively. Partly, mastitis was caused because there was no enough bedding straw, poor on farm hygiene, as well aas bioclimatic changes.
