The object of this study was to evaluate the effects of dietary supplementation of mulberry leaves and silkworm excreta ethanol extracts on weight performances, blood characteristics, cecal microflorae of chickens. Two hundred forty male broiler chicks(Ross) were fed diets for five weeks containing 0.1%(MLA) and 1%(MLB) of mulberry leaves ethanol extracts, and 0.1%(SEA) and 1%(SEB) of silkworm excreta ethanol extracts. Weight performance did show no significant difference in all test groups which were fed with supplementation of mulberry leaves and silkworm excreta ethanol extracts. They showed better weight gain and feed conversion than the negative control group which was fed only with forage without antibiotics. ABTS(2'-azine-bis[3-ethylbenzothiazoline-6-sulfonic acid]) test was conducted to investigate free radical scavenging activity of blood in tested groups. ABTS scavenging activities of tested groups were higher than control groups in significant level, though there was no significant difference(P = 0.396). Specifically, MLB group showed the highest scavenging activity. Blood-level concentration of MDA, which is an indicator of lipid peroxidation, was also decreased in tested groups and the lowest level was observed in SEA(P = 0.001). As storage time increased at 4 o C, muscle-level MDA concentrations of all tested groups were generally increased and significant difference was obsereved between tested groups and controls in total increase of MDA concentration(P = 4.417 × 10 -3). In cecal microflorae, SEA and SEB showed decreased total microbe population compared to NC(P = 6.462 × 10 -5) and even to PC. Supplementation of mulberry leave and silkworm excreta ethanol extract did show a similar inhibition effect against Salmonella sp., furthermore, MLB did enhanced the growth of Lactobacillus sp.(P = 3.636 × 10 -7). In summary, ethanol extract of silkworm excreta may be a potential alternative of antibiotics for chicks. In addition, both of ethanol extracts supplementation to broiler chicks would be very useful not only to improve antioxidant effect of blood but also to suppress lipid peroxidation without any loss of weight performance in poultry farming.

This study was conducted to determine the possible application of mulberry silage as a functional feed in the feeding management of Hanwoo, Korean native cattle, for high quality beef production. Twenty Hanwoo steers in the last stage of fattening were randomly assigned to two groups with (MSS) or without (Control) supplemental mulberry silage. The Control group was fed on a standard total mixed commercial ration, while the MSS group was fed on a total mixed commercial ration formulated with mulberry silage at the rate of 10%, fresh matter basis, for 30 days. The mulberry silage contained active ingredients such as 1-deoxynojirimycin, γ-aminobutyric acid, and phenol compounds. In the present study, the oxidative stress biomarkers such as glutathione, superoxide dismutase, glutathione peroxidase, catalase, and glutathione-S-transferase were improved in the MSS group compared with the Control group. Electron spin resonance assays showed that 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was significantly elevated by 75.5% in the MSS group (P < 0.001). Moreover, the MSS group exhibited stronger scavenging activity against hydroxyl radicals, superoxide radicals, and alkyl radicals, and the radical scavenging activity occurred in a dose-dependent manner. Findings from the present study suggest that mulberry silage may be useful as a functional feed by improving the antioxidant activity against various reactive radicals for beef cattle.
