dc.description.abstract | This study was conducted to evaluate the effect of supplementation of ashwagandha (Withania somnifera) root powder and synbiotic at different levels in broiler diets on growth performance, serum biochemical profile, digestibility of nutrients, carcass characteristics and cost economics in broilers. One hundred and eighty, day old chicks were distributed randomly into six dietary groups each with three replicates of ten chicks and were offered broiler diets to meet the nutrient requirements (ICAR, 2013). Broilers were fed on maize-soya based pre-starter (0-2 weeks), starter (2-4 weeks) and finisher (4-6 weeks) diets. The six treatment groups were provided diets supplemented with various levels of ashwagandha (Withania somnifera) root powder and synbiotic (S) either alone or in combination as follows: Basal diet without antibiotics (T1) - as negative control, basal diet with antibiotics (T2) - as positive control, basal diet plus ARP at 10 g/kg feed (T3), basal diet plus S at 0.5 g/kg feed (T4), basal diet plus ARP at 10 g/kg feed plus S at 0.5 g/kg feed (T5), and basal diet plus ARP at 5 g/kg feed plus S at 0.5 g/kg feed (T6) which was iso-caloric and iso nitrogenous. Results indicated that supplementation of ashwagandha root powder and synbiotic either alone or in combination in the diet resulted in increased (p<0.01) body weight gain, improved (p<0.01) FCR, increased (p<0.01) performance index and improved (p<0.01) protein efficiency ratio while there was decrease (p<0.05) on overall feed intake of birds. The serum biochemical profile of broilers revealed that supplementation of supplementation of ashwagandha or synbiotic alone or in combination in the diet had no effect (p>0.05) on serum A/G ratio and creatinine levels. However, the serum total protein, albumin and globulin (p<0.01), HDL (p<0.05), serum calcium (p<0.05) and serum phosphorus levels (p<0.01) increased while the serum glucose, triglycerides (p<0.01), total cholesterol (p<0.05), LDL cholesterol (p<0.01), VLDL cholesterol (p<0.05), serum AST (p<0.01) and ALT (p<0.01) content decreased with supplementation of higher level of ashwagandha (10 g/kg feed) or (5 g/kg feed) plus 0.05% synbiotic in broilers as compared to the unsupplemented group. On the other hand, the serum urea levels increased linearly from T1 to T6 with combination of ashwagandha or synbiotic alone or in combination. The digestibility coefficients of DM, OM, CP, CF, EE and NFE significantly (p<0.01) increased with supplementation of ashwagandha or synbiotic either alone or in combination in the basal diet of broilers as compared to the unsupplemented group. Further, supplementation of ashwagandha root powder and synbiotic in broiler diets had no significant effect (p>0.05) on calcium, phosphorus and nitrogen retention when compared to control. Supplementation of ashwagandha (10 g/kg feed) + 0.05% synbiotic in the diet had increased (p<0.05) carcass characteristics parameters viz., carcass yield, ready to cook yield, breast meat yield, weight of heart and dressing percentage while there was no effect (p>0.05) weight of drumstick, breast meat %, giblet % and relative organ weights viz., weights of liver, gizzard, spleen and giblet among the treatment groups in broilers. Further, significant reduction in mortality is observed in ashwagandha and synbiotic supplemented groups. The feed cost/kg gain decreased by ₹ 6.23 in T2, ₹ 0.62 in T3, ₹ 3.20 in T4, ₹ 7.27 in T5 and ₹ 4.64 in T6 groups of broilers fed diets supplemented with ashwagandha root powder and synbiotic at varying levels as compared to the control (T1). Thus, based on the results it can be concluded that ashwagandha root powder up to 10g/kg feed, combined with synbiotic at 0.5g/kg feed as feed supplement, can be used as an alternative to antibiotic growth promoter duly optimising feed cost and ensuring enhanced production performance in broilers. | |
