Abstract

Forty-eight lactating Holstein Friesian cows were utilized to assess impact of supplementing probiotic ZAD (mixture of live bacterial cells and enzymes) compared with T5X (antitoxins product) on some productive, reproductive and antitoxins activity parameters. we have divided the animals to three experimental categories (16 each). The first category, control treatment, was fed basal diet without any supplements. The second category, ZAD treatment, was fed basal diet supplemented with ZAD probiotic (1.1 L/ton). The third category, T5X treatment, was fed basal diet supplemented with T5X antitoxins product (1.1 Kg/ton). Milk yield was recorded. we have collected and analyzed milk samples, blood samples and feed samples in order to constitutes. Time-interval between calving and fertilizing artificial insemination and pregnancy rate were recorded. The gained outcomes demonstrated that milk yield was significantly raised by ZAD treatment than other treatment. Milk components yield were significantly raised by ZAD probiotic and T5X treatments than control. Blood serum total protein, albumin, globulin, glucose, urea and total lipids were not significantly influenced by treatments. Total aflatoxins in concentrate mixture and aflatoxin M1 in milk were significantly diminished by ZAD and T5X than control. Number of days between calving and fertilized artificial insemination were diminished by treatments than control. Pregnancy rate was significantly raised by ZAD
probiotic than T5X and control treatments, respectively. The overall conclusion of this study illustrated that Probiotic ZAD, potentially, has antitoxins activity leading to reinforcing the productive and reproductive performance of lactating cows.
