Influence of virginiamycin on phosphorus utilization by broiler chicks

An experiment was conducted with day-old Cobb feather-sexed chicks to determine the influence of virginiamycin on phosphorus. When the average of the three levels of phosphorus were combined, utilization, body weights, and bone ash at 21-days of age were improved by the addition of virginiamycin to the diet. Also the amount of phosphorus required to produce a gram of body weight was decreased by the addition of virginiamycin to the diet.
