Evaluation of Gentian Violet and Copper Sulphate as Fungi Inhibitor in Broiler Diet

Total sixty four straight run broiler chicks of two daysold were fed a control diet and diet supplemented with Fungi inhibitor (FI): Gentian violet (GV), Copper sulphate (CS), GV+CSto evaluate the effect of dietary FI on the performance characteristics of broiler. The levels of GV, CS and GV+CS were 0.05%, 0.06% and 0.025%+0.06%, respectively. Dietary FI did not alter the growth rate, feed intake, feed conversion efficiency and survivability. However, the use of CS and GV+CS improved growth rate and feed utilization to some extent. Dietary FI protected the liver and gizzard enlargement. The FI supplementation was effective in improving dressing yield and therefore, increased profitability. The CS appeared to be the more effective FI than GV. It was concluded that supplementation of CS to diets would decrease the feed cost per kg live broilers and may increase meat yield and profitability.
