Effect of dietary supplementation of Pulvis Curcuma Longa on the voluntary feed intake, nutrient digestibility and Growth performance of Broiler rabbits under summer stress

Eighteen four weeksʹ old weaned Broiler rabbits of comparable body weights were allotted to three dietary treatment groups of six rabbits in each group namely T0 (basal control diet, T1 (basal diet added with Turmeric (Curcuma longa) Rhizoid Powder, TRP, at the ratio of 150mg) and T2 ( basal diet added with TRP at the ratio of 300mg/100g diet). Feeding cum growth trial and digestion trial were during summer months of April, May and June to study voluntary feed intake, growth rate and nutrient utilization by the experimental animals. TRP included in the diets of experimental groups consisting 6.72 % CP, 5.04% ether extract, 3.96% crude fibre, 7.85% total ash. Depression in voluntary feed intake due to summer stress did not alter due to the inclusion of turmeric powder. The weekly mean body weight gain, feed conversion efficiency and digestibility of nutrients did not show significant difference by the supplementation of turmeric rhizome powder in the diets of rabbit in present study.
