Abstract
The study investigated the effect of dietary supplementation of dried Bael fruit powder
on growth performance, nutrient utilisation of broiler chicken, blood biochemical parameters,
oxidative stress indices, sensory evaluation and histomorphological change in jejunum and
liver of broiler chicken.
In the present experiment, a total of 150-day-old broiler chicks were randomly divided
into five groups. The diets were formulated according to the nutrient specification of broiler
diet (ICAR, 2013) using maize, soy DOC, rice bran oil, LSP, DCP, vitamin and mineral
premixes. There were 5 dietary groups T1, T2, T3, T4 and T5. T1 was basal diet without AGP
as negative control, T2 contained basal diet supplemented with Bacitracin @150mg/kg diet
and diet of T3 to T5 group contained basal diet along with graded level of DBFP @ 1%, 1.5%
and 2% respectively. Proximate analysis of bael fruit powder revealed 4.09% Crude protein
5.23 % , Crude fiber 1.36 %, Ether extract 0.01% Calcium and 0.09% phosphorus. For analysis
of results obtained data were analysed by ANOVA using completely randomized design.
The results revealed significantly increased overall body weight, weekly cumulative
weekly weight gain and overall feed convertion ratio of birds supplemented with higher level
of DBFP (2%) in group T5 as compared to NC (T1). The supplementation of DBFP and AGP
had significantly increased the DM metabolizability, CP metabolizability and N retention in
the supplemented groups (T2, T3,T4 and T5) as compared to T1. However, the ether
metabolizability, Ca and P retention did not differ significantly amongst the groups. Similarlythe carcass traits and cut up yields did not differ significantly amongst the groups. The present
experiment also revealed significantly decreased serum cholesterol, blood glucose ,creatinine
and ALT activity with an increase in DBFP supplementation @ 1.5-2% in T4 and T5 as
compared to T1. The data of total protein , albumin, globulin concentration revealed non
significant difference between the groups(T1-T5). The dietary supplementation of dried bael
fruit powder at 2% level significantly decreased the MDA concentration in birds of T5 as
compared to T1 and T2, however no significant difference was observed between T5,T4 and
T3. Similarly the reduced glutathione activity significantly increased in group T5 and T4 as
compared to T1,T2 and T3, however no significant difference was observed between T4 and
T5. The histological section of jejunum showed significantly improved villus height and
VH:CD ratio in T4 and T5 supplemented with 1.5 and 2% dried bael powder respectively. No
significant difference was observed on the overall palatability of meat due to dietary
supplementation of varying level of DBFP. The supplementation of dried bael fruit powder @
2% level(T5) increased net profit per kg live wt was 22.38 as compared to Rs 29.40 in AGP
supplemented (T2) group and Rs 6.05 in NC(T1). Thus present study concluded that dried bael
fruit powder @ 2 % can be effectively used as safe and natural growth promoter in broiler
chickens.
