abstract
The present investigation was undertaken to study the impact of anionic supplements on postpartum performance of dairy cows. Forty numbers of cross-bred dairy cows in their third lactation period were selected for the present study (control - 20 cows; Anionic salt supplementation – 20 cows). Reducing DCAD by increasing dietary acidity or employing anionic salts has been efficacious and cost effective in the prophylaxis of hypocalcaemia. The results of this study, based on the data available, suggest that DCAD has a significant effect on a variety of performance indicators including milk production, health status and reproductive performance. A sharp reduction in urinary pH was found after introduction of anionic mineral mix in trial group up to 21 days. A positive role for anionic mineral mixture intake between groups for reducing the risk of retained placenta was identified. A positive role for anionic mineral mixture intake between groups for increased milk yield was identified. Findings of this experiment suggest that feeding of anionic mineral mixture in prefresh period improves the performance of dairy cows with respect to their production and reproductive performance.
