Abstract
The present study was conducted to study the effect of supplementation of turmeric, ginger and their combination at two different levels on growth performance, serum biochemical profile, nutrient utilization, carcass characteristics and sensory evaluation of meat in broilers. One hundred and sixty eight day old chicks distributed randomly to seven dietary groups each with four replicates of six chicks and were offered broiler diets to meet the nutrient requirements (BIS, 2007). During the experiment, turmeric, ginger and their combination were supplemented to the basal diet in pre-starter, starter and finisher phases viz. basal diet (T0), BD + 0.5% turmeric (T1), BD + 0.75% turmeric (T2), BD + 0.5% ginger (T3), BD + 0.75% ginger (T4), BD + 0.25% turmeric and 0.25% ginger (T5), BD + 0.50% turmeric and 0.50% ginger (T6).
Results indicated that the body weight gains increased (P<0.01), overall feed intakes decreased (P<0.01) while FCR improved (P<0.01) with supplementation of either turmeric or ginger at 0.50 and 0.75 % or a combination of turmeric and ginger at 0.25 and 0.50% in the diet as compared to the control. The serum biochemical profile of broilers revealed that supplementation of either turmeric or ginger at 0.50 and 0.75 % or a combination of turmeric and ginger at 0.25 and 0.50% in the diet had no effect (P>0.05) on serum total protein, albumin, AST, ALT, creatinine and serum phosphorous content while it decreased significantly (P<0.01) the serum glucose, triglycerides, total cholesterol, LDL cholesterol and VLDL cholesterol content and increased significantly the serum globulin (P<0.05), HDL cholesterol (P<0.01) and serum calcium (P<0.01) content of broilers as compared to the control.
Supplementation of either turmeric or ginger at 0.50 and 0.75% in the diet or a combination of turmeric and ginger at 0.25 and 0.50% level in the diet had no effect (P>0.05) on digestibility of DM, OM, CP, CF, EE and NFE. Similarly, there was no effect (P>0.05) on percent nitrogen, calcium and phosphorus utilization in broilers. Furthermore, supplementation of either turmeric or ginger at 0.50 and 0.75% in the diet or a combination of turmeric and ginger at 0.25 and 0.50% level in the diet had increased (P<0.01) the carcass yield (g), dressing percent, ready to cook yield (g) and shank weight (g) while there was no effect (P>0.05) on weight of head, heart, liver, gizzard and giblets in broilers. Similarly, supplementation of turmeric or ginger at 0.50 and 0.75% or a combination of turmeric and ginger at 0.25 and 0.50% level in the diet had no effect (P>0.05) on colour, flavour, juiciness, tenderness and overall acceptability of meat in broilers. The feed cost/kg gain decreased by ₹ 5.64 in T1, ₹ 7.16 in T2, ₹ 6.32 in T3, ₹ 2.84 in T4, ₹ 2.32 in T5 while it increased by ₹ 1.5 in T6 groups of broilers fed diets containing turmeric, ginger and their combination as compared to the control. Thus, the present study indicated that turmeric or ginger can be supplemented up to 0.75% level while their combination can be supplemented up to 0.25% level in the diet of broilers without any adverse effect on production performance of broilers.
