Abstract
A feeding trial was conducted to discern the effect of dietary incorporation of pea (Pisum Sativum L.) pods residue powder by replacing rice polish on growth performance, nutrient utilization, haemato-biochemical parameters, carcass traits, sensory evaluation and economics of broiler chickens. A total of 120, day-old broiler chicks were divided randomly into 4 treatment groups with 3 replicates in each i.e. 10 broiler chicks per replicate. Chicks of T1 (control) were fed basal diet with rice polish as one of the feed ingredients, whereas in treatment groups T2, T3 and T4, basal diet was incorporated with pea pods residue powder at 50, 75 and 100 per cent levels by replacing rice polish, respectively. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). Feed intake and body weight changes in broiler chicks were recorded at weekly intervals and a metabolism trial of 3 days collection period was conducted during the 6th week of feeding trial. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. Results of feeding trial indicates that during starter phase (0-21 days), the body weight gain of broiler chicks of treatment groups T2 and T4 were significantly (P<0.05) higher than T1 and T3 treatment groups. Performance index was also found higher in T4 treatment group. During 21- 42 days (finisher phase), body weight gain, feed intake, FCR and performance index were statistically similar among the treatment groups. During whole experimental period (0-42 days), incorporation of pea pods residue powder by replacing rice polish in experimental diet showed similar broiler chicken performance in terms of feed intake, body weight gain, FCR and performance index. Nutrient utilization in terms of dry matter, crude protein, crude fat and organic matter did not differ significantly (P>0.05) among different groups. Sensory characteristics viz., juiciness, texture, overall acceptability (P<0.05) and appearance (P<0.01) were significantly higher in T4 treatment group. Carcass traits were similar among the treatment groups. The protein content in breast (P<0.05) and thigh (P<0.01) muscle were higher in pea pods residue powder incorporated groups. No significant (P>0.05) differences were observed in haematological values among different groups and all the values were in normal range. Significantly (P<0.05) lower serum SGPT activity and increase (P<0.05) in serum total protein content were recorded in broiler chickens of treatment groups fed pea pods residue powder in place of rice polish. There was non-significant difference in serum albumin, globulin, glucose, cholesterol and triglycerides levels. Feed cost per kg body weight gain was similar among the treatment groups. It is concluded that incorporation of pea pods residue powder by replacing rice polish in diet of broiler chickens did not affect growth performance, nutrient utilization, haematological contents, carcass weight and feed cost per kg body weight. Thus rice polish could be replaced completely by pea pods residue powder in the diet of broiler chickens.
