This study was conducted to evaluate the feeding value of black soldier fly pupa (BSFP) on fecal microorganism, immunoglobulinm egg quality and egg production laying hens. One hundred twenty laying hens were assigned to 4 treatments (0, 5, 7 and 10% BSFP) with 3 replicates for 8 weeks. The formulae of 4 experimental diets were modified to contain 18% CP and 2,900 kcal/kg. All the treated groups differed in feed intake, egg production, egg weight and egg mass compared to those of a control group. The egg weight and production were increased (p < 0.05) in BSFP groups compared to the control. The HDL-C was increased (p < 0.05) in BSFP groups compared to the control. The level of immunoglobulin IgG and Haugh unit were increased (p < 0.05) in BSFP groups compared to the control. These result suggested that the addition of BSFP to the layer diet could improve the egg quality and the laying performance.
The objective of this study was to determine the feeding effect of a diet containing Cordyceps with fly pupa on the changes in blood lipid profile from broiler chickens, fatty acids and thiobarbituric acid reactive substances (TBARS) in chicken meat. A total of 360 chicks (Ross strain 308) were divided on hatch day into four treated groups with respect to a 35-day feeding regimen: T1 (control group), T2 (2.0% Cordyceps with fly pupa), T3 (3.5% Corceps with fly pupa) and T3 (5.0% Cordyceps with fly pupa). Blood triacylglyceride and total cholesterol level was significantly decreased by 5.32-10.63% and 9.23-12.62%, respectively, in groups T2, T3 and T4 when compared to T1 (p<0.05). Water holding capacity was significantly highest in T2 (p<0.05), while there were no significant differences among groups T2, T3 and T. In chicken meat, the ratio of saturated fatty acid to unsaturated fatty acid was high in the T3 and T4 groups, the ratio of n-6 to n-3 fatty acid was low in the T2, T3 and T4 groups and oleic acid (18:1n-9) was high in the T2, T3 and T4 groups, when compared to T1 (p<0.05). TBARS tended to increase according to the storage time (in days), and was significantly lower in the chicken thigh muscles with skin in groups T2, T3 and T4 as compared to T1 (p<0.05). These results suggest that a diet containing 2.0-3.5% of Cordyceps with fly pupa may decrease blood lipid and improve both the shelf-life and quality of broiler chicken meat.
