EFFECT OF SOLVENT EXTRACTED KARANJ CAKE WITH ENZYMES AND LIVER TONIC SUPPLEMENTATION ON PERFORMANCE, NUTRIENT DIGESTIBILITY AND ECONOMICS OF BROILER CHICKEN
An experiment was conducted to evaluate the effect of dietary inclusion of solvent extracted karanj cake (SKC) and isoÂ propyl alcohol (IPA) treated SKC supplemented with protease (4000 U/kg), phytase (400 U/kg) and liver tonic (0.1%) onÂ performance, nutrient digestibility and returns over feed cost in broiler chickens. The inclusion of control and karanj cake were
included in diets on isocaloric and isonitrogenous basis at graded (6%) level making 12 treatments (T1 to T12). A total of 360 dayoldÂ commercial broiler chicks, which were distributed in a randomized block design into 12 groups with 6 replicates of 5 chicks each.Â The chicks were housed in battery brooders and fed experimental diets from 1 to 42 days of age. The results revealed thatÂ inclusion of IPA treated karanj cake and SKC at 6% level treated with enzymes and liver tonic supplementation significantly did not
improve the body weight gain, feed intake and feed conversion ratio compared to control groups. The percent retention of dryÂ matter and crude protein were significantly (P<0.05) higher in control group compared with 6% SKC and IPA treated karanj cakeÂ with enzymes or liver tonic supplementation at 6th week of age. Mortality on karanj cake diets was within the limits. The 6% IPAÂ treated karanj cake & SKC of the dietary treatments with or without supplementation of enzymes and liver tonic recorded returnsÂ over feed cost was lower compared to control. It can be concluded that, supplementation of enzymes / liver tonic could not alleviate
the toxic effects of solvent extracted karanj cake or IPA treated karanj cake at 6% level in the diet.
