Abstract
The present investigation was carried out to study the effect of incorporation of onion (Allium cepa) powder as feed additive at different levels on growth performance, serum biochemical profile, anti-oxidant profile, digestibility of nutrients, carcass characteristics and cost economics in Japanese quails. One hundred and fifty, day old quail chicks were distributed randomly to five dietary treatments each with three replicates of ten chicks each and were offered experimental diets to meet the nutrient requirements (NRC, 1994). During the experiment, onion powder was incorporated at 0 per cent (T1; Control), 0.5 per cent (T2), 1 per cent (T3), 1.5 per cent (T4) and 2 per cent (T5) levels in iso-caloric and iso-nitrogenous broiler quail diets.
Results indicated that incorporation of onion powder from 0 to 2 per cent level in the diet had no effect (p>0.05) on feed intake and protein efficiency ratio in quails as compared to the control. Whereas, the study indicated that the body weight gain (p0.05) on serum total protein, albumin, globulin, A/G ratio, glucose, AST, ALT, BUN, creatinine, serum calcium and phosphorous content as compared to the control. Whereas, the serum triglycerides (p0.05) on catalase activity. However, the SOD activity (p0.05) with increase in the level of incorporation of onion powder up to 2 per cent in the diet of Japanese quail as compared to the control. Further, onion powder incorporation in quail diets significantly improved calcium retention (p0.05) on carcass yield, dressing percentage, ready to cook yield and per cent weight of, liver, gizzard and giblet as compared to the control and there was increased in weight of heart (p<0.01) with increase in the level of incorporation of onion powder up to 2 per cent in the diet of Japanese quail as compared to the control. The feed cost ()/kg gain was numerically increased with increase in the level of onion powder from 0 to 2.0 per cent in the diet, but the difference was not significant.Thus, based on the overall results of the study, it was concluded that onion powder can be incorporated up to 2 per cent level in quail diets without any adverse effect on Japanese quail performance.
