title: [The effect of Zindep on B-lymphocyte levels in pregnant cows].
abstract: In the present study the immunomodulation effects of the Zindep preparation, based on elementary zinc and zinc oxide, were followed on the humoral response of gravid cows in the 8th and 9th months, a week after parturition and in calves immediately after parturition and on day 15 of their life. An increased level of B-lymphocytes was observed on days 2, 5, 8, 15, 30 and 50 of the experiment. The highest average values were recorded in the experimental group on days 8 and 15 of the experiment. The mentioned values were statistically significant (T-test) at the level 0.05 and 0.01. The average values of B-lymphocytes in cows after parturition reached 22.3% in the cows of the experimental group and 20.5% in the control group. No pronounced differences in the number of B-lymphocytes in the calves of both followed groups were recorded. The statistical evaluation of the values obtained in the cows after parturition as well as in the calves was not carried out due to a small number of samplings.
