Abstract
ABSTRACT :
An experiment was conducted with three types of herbal preparations (amla, turmeric and tulsi) either alone or in combination in nine dietary treatments to study the performance of broilers.
The body weight gain was significantly (P<0.05) affected in broilers during starter, finisher and overall periods. However, the best weight gain was noticed in herbals combination (T8) group compared to control (T1) group throughout the experimental period.
The feed intake was significantly (P<0.05) affected in broilers during starter period but it was highly significantly (P<0.01) affected among different groups during finisher and entire periods. It was observed that higher feed intake in T8 group compared to all other groups during the different phases of growth period. The feed efficiency was not significantly different among treatment groups during all the growth phases. Furthermore, the best feed efficiency was noticed in T7, T8 and T9 compared to control group (T1). Eventhough the feed cost per kg live weight gain was significantly (P<0.01) different among treatment groups, the feed cost per kg live weight gain was the lowest in T8 group compared to all other groups.
The different types of herbals either alone or in combination at 0.25 and 0.5% levels in broiler diets did not influence the carcass traits, SGOT, SGPT and serum cholesterol levels.
The immune response (HI titre) to ND vaccination did not differ significantly, but it was found to be better in broilers fed different herbals either alone or in combination compared to control.
It is inferred that, supplementation of tulsi and herbal combination at 0.25% level in broiler diets respectively can reduce the cost of production without affecting the performance of broilers.
