Levamisole-Phosphate Used In Dairy Cattle on Pre- Parturient and Reproductive Performance during Post-Parturient Period.

Abstract
In the milk activity, the problems that affect the reproductive tract of postpartum females such as retention of placenta, metritis and endometrites, cause great losses, such as decrease on milk production, drug expenses, milk discharge and low reproductive performance, are generally related to the animal's systemic immune status. For this reason, several products are indicated as immunostimulators or immunopotentiators in pre-calving cows. In this work, two groups of bovine, Jersey andHolstein females were tested for the immunostimulatory activity of Levamisole, a parasite control drug that has on its properties an increase in the immune response in animals. The work consisted in the application of Levamisole twice in the prepartum and collections of serum and colostrum from the animals during the experiment, measuring the immunoglobulins type G by immunoaffinity with protein A. There were no differences between the races or between the control groups and the groups This is in agreement with several authors that the use of levamisole as immunopotentiator does not show results in bovine females, nor was there any difference in the reproductive performance of the same, regardless of the race studied.
