Effect of Detoxified Karanj Cake on the Performance of Broilers

Abstract

An experiment was conducted to evaluate the effect of solvent extracted karanj cake (SKC), SKC treated with 2% NaOH, 1% NaOH + 1% HCl treated SKC and 3% iso propyl alcohol (IPA) treated SKC on performance of broilers. The experiment comprised of 13 dietary treatments, T1 as control (without karanj cake). SKC diets at 3, 6 and 9% levels were designated as T2, T3 and T4; NaOH treated SKC at 3, 6 and 9% levels were designated as T5, T6 and T7; NaOH + HCl treated SKC at 3, 6 and 9% levels were designated as T8, T9 and T10; while T11, T12 and T13 comprised of 3%, 6% and 9% IPA treated SKC diets, respectively. Six replicates were allocated to each treatment, and each replicate comprised of five birds. The results revealed that inclusion of IPA treated karanj
cake at 3% maintained similar body weight gain as compared to the control group. At 6 and 9%, the IPA treated cake improved the performance compared to the SKC fed group. Processing of SKC with NaOH or NaOH + HCl
yielded marginal improvement in body weight gain of chicken. The inclusion of SKC, NaOH treated SKC and NaOH + HCl treated SKC reduced feed consumption. Feed conversion ratio with IPA treated SKC was
comparable to control even at 6% inclusion level. Economics of feeding of karanj cake-based diets indicated that IPA treatment increased returns over feed cost than that of SKC diet. It was concluded that IPA treated SKC
could be safely incorporated at 3% level in broiler chicken diet.
