At present time, mastitis is considered, in the farming scope, one of the most expensive diseases due to the economic losses from the productive point of view. The objective of this study was to evaluate the effect of the clinical and subclinical mastitis in milk bovine females on some plasmatic metabolic parameters. Thirty racially mixed cows Holstein were used from a commercial milk farm which is located in Quibor, Lara, Venezuela, managed under the same conditions and distributed in three groups of 10 animals each: healthy cows, with subclinical mastitis, and clinical mastitis. The concentrations of glucose, total cholesterol, and its fractions Col- HDL and Col-LDL, triglycerides, proteins, and albumen were quantified by commercial kits. In both types of mastitis there was a highly significant increase (P<0,002) on the plasmatic glucose, probably by smaller use or mobilization from the endogenous reservoirs. The triglycerides were not modified, but total cholesterol showed a significant decrease. The Col-HDL fraction from cows with clinical mastitis, it was observed a significant decrease. On the other hand, there was a highly significant increment of total proteins in both groups (P<0,001); however, the modification of its fractions (albumen and globulins) were different in each type from mastitis.
