Abstract:
Effect of protein, energy and probiotics on juvenile growth traits and economic of colour dual chicks was evaluated by feeding diet having 3 protein levels i.e. P₁ (17% cp), P₂ (19% cp), P₃ (21% cp), 2 energy levels i.e. E₁ (2700 Kcal ME/kg), E₂ (2900 Kcal ME/kg) and 3 probiotic levels i.e. B₀ (0%), B₁ (0.025%, B₂ (0.05%) in a factorial designed experiment, conducted during summer period. Body weight (BWt), Feed intake (FI), Feed efficiency (FE) and Shank length (SL), were similar in P₂ and P₃ protein and found significantly higher than P₁ lower protein diet. Breast angle (B A), and carcass yield were significantly higher in P₂ than P₁ and P₃ protein diets. Significantly better FE, BA and carcass yield were recorded in E₂ energy diet. Body wt, FI and SL were non significantly different in E₁ and E₂ diet. Probiotic levels B₁ and B₂ did not differ significantly for BWt, FE, BA, SL and carcass yield and found significantly better than B₀ diet for all these traits. FI was significantly higher with increased level of probiotics. Cost benefit analysis showed that P₂ protein, E₂ energy and B₂ probiotic levels in diet fetched higher net return at 10^th week of age during summer.
