Higher intake of dietary protein has been negatively associated with metabolic changes in blood serum and reproductive performance in dairy cows. The aims of this study were to establish the incidence of cystic ovarian disease, its seasonal variation and to examine the serum protein, urea and aspartate aminotransferase in blood serum in cows with. Having spent the last one year monitoring we identified 32 - 21% cases of follicular cysts in one farm. We found higher percentage COD - 41% and 50% from all reproductive disorders during months June and July, although the average RD was with out changes. Average concentration of total proteins during June-July was 83.87±2.95: 81.46±6.48g/l, which is within the normal values ranging from 65 to 85 g/l. Serum urea level - 6.87±0.84; 8.21±2.0mm/l was increased - normal to 6.6. AST showed an increase - 135.33±37.38: 125.13±19.5u/l too. Higher rates of SP, U and AST in lactating cows with COD may indicate chronic effects of higher protein intakes as well.
