Influence of Dietary Vegetable Wasps with Fly Pupa on Gastrointestinal Tract Microflora, Carcass Characteristics and Growth Performance in Broiler Chickens

Park Byung-Sung    

Abstract: This study evaluated the effects of the addition of different levels of VWFP (Vegetable Wasps with Fly Pupa) on the growth performance, carcass characteristics and gastrointestinal microorganism populations of broiler chickens. About 400 animals (Ross 308, 1 day old) with an average body weight of 45 g were sorted randomly into 4 treatment groups and 4 repetition groups of 25 animals each. The treatment groups were divided into a control group not fed with VWFP and treatment groups fed with VWFP 2.0, 3.5 and 5.0%. The feeding test lasted 5 weeks separated by the grower period (0-21 days) and the finisher period (22-35 days). Although, the broilers’ weight gain and feed efficiency were significantly higher in the VWFP 3.5% (p<0.05) group throughout the entirety of the test period, no statistically significant differences were noted between the control group and other treatment groups. Triglyceride in the blood, total cholesterol and LDL-C were significantly lower in the VWFP treatment groups than in the control group (p<0.05). The blood lipid reduction rate ranged from 5.32-10.63% for triglycerides from 9.23-2.62% for total cholesterol and from 44.67-53.81% for LDL-C in the VWFP treatment groups relative to the control group. The abdominal fat weight ratio was reduced significantly in the VWFP treatment groups (p<0.05) compared with the control group with a reduction rate range of 17.67-21.68%. Broiler carcass weight, carcass rate and breast muscle, skin and thigh muscle weights against carcass weight were significantly higher in the VWFP 3.5% treatment group and a statistically significant difference was noted between the control group and other treatment groups (p<0.05). Enteropathogenic E. coli and Salmonella were lower in the VWFP treatment groups than in the control group whereas the beneficial bacteria Bifidobacteria were significantly higher in the VWFP treatment groups than in the control group (p<0.05).
