Abstract

This study was conducted to determine the effect of dietary supplementation of bentonite on the immune status and reproductive performance of lactating Friesian cows. A total of 30 pregnant Friesian cows (4-6 years of age) were divided into three groups (10 cows in each). In the 1st group; G1, animals were fed the control diet, while those in the 2nd; G2 and 3rd; G3 groups were fed the control diet supplemented with 20 or 40 g bentonite/kg concentrate, respectively, from 60 days prepartum up to 120 days postpartum. Blood samples were taken at estrus and 120-d postpartum. Results show that calf weight at calving and placental drop time improved (P<0.05) in G3, while uterine horn symmetry and cervical closer improved in G2 and G3 compared with G1. Plasma immunoglobulins (IgG, IgM, and IgA) increased (P<0.05) in G3 than in G1 and G2. Count of RBCs and WBCs, hemoglobin, and PCV improved (P<0.05) by both treatments, being the highest (P<0.05) in G3. Interval to first estrus, service period, and days open were the best (P<0.05) in G3. Concentration of P4 was the lowest at estrus, and the highest at 120-d postpartum in G3. Number of services/conception and pregnancy rate were 1.4 and 50% in G1, 1.6 and 80% in G2, and 1.4 and 100% in G3.
