Healthy meat production of broiler fed microparticle-protein diet with inclusion of inulin derived from dahlia tuber extract

Abstract

The present study was conducted to evaluate the healthy edible meat characteristic of broiler due to feeding effect of microparticle-protein diet with inclusion of inulin from dahlia tuber extract. Fish and soybean meal were exposed to ultrasonic bath to obtain microparticle prior to feeding trial. 160 broilers (2-week old) were allocated into 4 treatment. Treatments were tested as follows T0: 21% intact protein diet, T1: 18% intact protein diet, T2: 18% microparticle-protein diet, T3: Diet T2 + 1.2% dahlia inulin extract. A completely randomized design with 4 treatments and 5 replications (8 birds each) was arranged. Intestinal Escherichia coli, heterophyl-lymphocyte (H/L) ratio, meat protein and fat mass, meat cholesterol, and carcass weight were the parameters observed. Analysis of variance was applied, and continued to Duncan test. Results showed that all parameters, except carcass weight, were significantly (P<0.05) affected by dietary treatments. Escherichia coli count, H/L ratio, meat cholesterol, were significantly (P<0.05) decreased by T2 and T3 treatments. Meat fat mass was reduced by T3 treatment, but carcass weight was not affected by any treatmnets. In conclusion, diet composed of 18% microparticle protein with inclusion of 1.2% inulin extract produces healthy edible meat of broiler characterized by lower meat fat mass and cholesterol with higher meat protein mass.
