| dc.description.abstract | A feeding trial was conducted to discern the effect of dietary supplementation of mannan-oligosaccharides and citric acid on growth performance, nutrient utilization, carcass traits and haemato-biochemical parameters in commercial broiler chickens. A total of 100, dayold broiler chickens were divided randomly into 5 treatment groups with 2 replication each i.e. 10 broiler chickens per replicate. Chickens of treatment T1 (control) were fed basal diet (starter and finisher diet), whereas in treatment groups T2, T3, T4 and T5, basal diet was incorporated with 0.1% mannan-oligosaccharides (MOS), 0.2% citric acid, 0.05% MOS with 0.1% citric acid, and 0.1% MOS with 0.2% citric acid, respectively, as feed additive. The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). A metabolism trial was conducted during the 6th week of feeding trial. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. During the starter phase (0-21 days), the weight gain was improved significantly in broiler chickens of treatment groups T5 (469.85 g) fed diet is supplemented with 0.1 % MOS in combination with 0.2% citric acid followed by T4 (452.75 g) fed diet supplemented with 0.05% MOS and 0.1% citric acid, T3 (443.40 g) fed diet supplemented with 0.2% citric acid as compared with T2 (425.85 g) fed diet supplemented with 0.1% MOS and T1 (390.75 g) fed diet supplemented with control diet. During 21- 42 days (finisher phase), the average body weight gain was 1025.3, 1062.8, 1118.0, 1235.6 and 1251.4 g in broiler chickens of treatment groups T1, T2, T3, T4 and T5 respectively and differed significantly among different groups. Feed intake was not differed significantly in broiler chickens of various treatment groups. Feed conversion ratio, performance index broiler chickens differed significantly among treatment groups. During entire feeding trial period (0-42 days), supplementation of MOS and citric acid in the basal diets improved growth performance in terms of body weight gain, feed conversion ratio, performance index. The average cumulative body weight gain was 1416.1, 1488.6, 1561.4, 1688.4 and 1721.3 g in broiler chicks of treatment groups T1, T2, T3, T4 and T5, respectively and differed significantly (P<0.05) among different groups. There was no significant difference in feed intake. The nutrient utilization improved significantly among different treatment groups of broiler chickens. The various carcass traits in broiler chickens were not affected but the breast and thigh part differed significantly due to feeding of MOS and citric acid. There was no significant differences in protein and ether extract content of breast and thigh muscles. No significant difference was observed in haematological parameters in broiler chickens of different treatment groups. There was significant (P<0.05) reduction in serum cholesterol in broiler chickens of treatment groups T5 (132.05 mg/dl) followed by T4 (133.02 mg/dl) and T2 (140.78 mg/dl) as compared with T3 and T1. Serum triglycerides content significantly reduced in all the treatment groups compared with control. There was no significant difference in serum total protein, albumin, globulin and glucose concentrations and serum ALP, ALT and AST activities among the different treatment groups. The dietary supplementation of MOS in combination with citric acid at both levels showed similar performance in broiler chickens. It can be concluded that inclusion of 0.05% mannan-oligosaccharides and 0.1% citric acid in the diet of broiler chickens improved growth performance, nutrient utilization and reduced serum cholesterol and triglycerides which in turn is beneficial in broiler chickens. | en_US |
