Abstract
A feeding trial was conducted to discern the effect of dietary incorporation of tejpatta (Cinnamomum tamala) powder and sahjan (Moringa oleifera) leaf powder on growth performance, nutrient utilization, carcass traits and haemato-biochemical parameters in commercial broiler chickens. A total of 120, day-old broiler chicks were divided randomly into 4 treatment groups with 3 replicate each i.e. 10 broiler chicks per replicate. Chicks of treatment T1 (control) were fed basal diet (starter and finisher diet), whereas in treatment groups T2, T3 and T4, basal diet was incorporated with 0.5% sahjan leaf powder, 0.5% tejpatta powder and 0.25% sahjan leaf powder with 0.25% tejpatta powder, respectively.
The feeding trial lasted for 42 days viz., 0-21 days (starter phase) and 21-42 days (finisher phase). Weekly feed intake, weight gain by weight were recorded is usually in terms of FCR, PI and growth rate was calculated. A metabolism trial was conducted during the 6th week of feeding trial to know the nutrient utilization. For carcass characteristics two broiler chicks from each replicate of all treatment groups were sacrificed at the end of feeding trial and the samples of breast and thigh muscle of broiler chicken were collected for proximate analysis and sensory evaluation. Blood samples were collected on 42nd day of feeding trial to study haemato-biochemical parameters. During starter phase (0-21 days), incorporation of tejpatta powder and sahjan leaf powder did significantly influence the weight gain and performance index. During 21- 42 days (finisher phase), body weight gain, feed intake, FCR and performance index were influenced statistically among treatment groups. During entire feeding trial period (0-42 days), incorporation of tejpatta powder and sahjan leaf powder in the basal diet showed significantly better performance in broiler chickens in terms of weight gain, feed conversion ratio and performance index in T4 group where the diet of broiler chicken was supplemented with 0.25% tejpatta powder with 0.25% sahjan leaf powder. Incorporation of tejpatta powder and sahjan leaf powder in the diet of broiler chickens did not affect nutrient utilization in terms of dry matter, crude protein, ether extract and organic matter
metabolizability. The dressing percentage without and with giblet (% of live weight) showed no significant differences among different treatment groups. Chemical analysis of breast and thigh meat revealed that dry matter, crude protein and total ash contents did not differ significantly but the values of ether extract were significantly lower in T4 treatment group. No significant difference was observed in haematological parameters among different treatment groups and all the values were in normal range. Significant (P<0.05) reduction in serum cholesterol and triglyceride level were recorded in broiler chicken fed diets incorporated with tejpatta powder and sahjan leaf powder alone or in combination. Serum cholesterol and triglyceride concentration were significantly lower value in broiler chicken of treatment group T4
supplemented with 0.25% tejpatta powder and 0.25% sahjan leaf powder. There was no significant difference in serum total protein, albumin, globulin and glucose concentrations as well as serum ALP, ALT and AST activities among the different treatment groups. No significant differences was observed in the sensory evaluation of meat of broiler chicken of different treatment groups as compared to control. Feed cost per kg body weight gain was significantly minimum in T4 treatment group as compare to control. It can concluded that incorporation of tejpatta (Cinnamomum tamala) and sahjan (Moringa oleifera) leaf powder in the diets of commercial broiler chickens had significant positive effect on their growth performance as well as lower level of serum cholesterol and triglyceride coupled with lower value of ether extract in the broilers chicken meat. Apart from this, average values for economics of broiler production (feed cost Rs per kg weight gain) was also lower in treatment group. Hence tejpatta and sahjan leaf powder may be recommended for feeding to commercial broiler chicken.
