This study was aimed to evaluate the utilization of banana peel meal as alternatives to substitution of corn in the diets based on the performance, carcass production, intestinal villi, the best type and utilization level of banana peel meal as corn substitution. A total of 105 male day old duck used in a completely randomized design (CRD), i.e. half of it (25%) and all of it (50%) replacing corn with banana peel meal PB= basal feed without banana peel meal; K25 and K50 = basal feed with Kepok banana peel meal; T25 dan T50 = basal feed with Tanduk banana peel meal; R25 dan R50 = basal feed with Raja banana pel meal. each treatment was done through 3 replications, with each replication consisted of 5 hybrid ducks. The data with significant differences were analyzed using orthogonal contrast. The paramater collected include performance (feed consumption, body weight gain, final weight, and feed conversion), carcass and abdominal percentage (carcass weight and carcass percentage). The results of the study showed that the utilization of banana peel meal on ducks had lower yields (P<0.05) in body weight gain, body weight, carcass weight, abdominal fat weight, but had higher feed conversion rather than basal feed treatment. It could be concluded that banana peel meal can not be used as substitution of corn in diets, because it can decrease the performance and carcass production of ducks, banana peel meal Kepok and Tanduk with level of 25% gives best performance and carcass weight when used as substitution of corn.
The purpose of this study was to investigate the characteristics of nanoencapsulated Phaleria macrocarpa fruits extract (NEPM) in drinking water and its effect on microbial population and histomorphology in the jejunal wall of broiler chickens. A total number of 200 male broiler chicks were distributed into 5 treatments with 4 replicates (10 birds in each replicate). The experimental treatments were control diet (T0; negative control), diet with tetracycline (T1; positive control), diet with 2.5% of Phaleria macrocarpa fruits extract (T2), diet with 2.5% NEPM (T3), and diet with 5.0% NEPM (T4). The diet was yellow corn and soybean meal that contains 20.44% CP, 2917.47 kcal/kg ME, 0.84% Ca, and 0.51% Pav. Variables evaluated were characteristics of NEPM, growth performance, intestinal microbial population (lactic acid bacteria (LAB) and Salmonella sp.), and intestinal histomorphology (villus height, crypt depth, and villus height to crypt depth ratio (VH : CD)). Data were analyzed using ANOVA in a completely randomized design. Orthogonal contrast test were used to separate mean of data when p-value differ significantly. Results showed that the size of NEPM was 778 nm with spherical shape and positive charges with the zeta potentials of +26.5 mV. Supplementing 5% of NEPM did not affect broiler growth performance, Salmonella sp. or crypt depth, but increased (p<0.05) LAB, villi height, and VH:CD. It can be concluded that 5.0% of NEPM in the drinking water had positive effect on the jejunal histomorphology and increased population of LAB while Salmonella sp. was not detected on all treatments.
This research was conducted to evaluate the effect of turmeric water extract, garlic and combinations of turmeric and garlic as feed additives in broiler diets on the physical and sensory quality of broiler meat. During the study, the chicken were given 5 feeding treatments, i.e. R0 (basal ration without phytobiotic and antibiotics) , R1 (basal diet + 0.015% zinc bacitracin + 2.485% filler), R2 (basal ration + 2.50% TE), R4 (basal ration + 2.00% GE + 0.50% filler), and R5 (basal ration + 2.50% TGE). The base diet was composed of: yellow corn, meat and bone meal, poultry meat meal, soybean meal, oil, mineral mix, calcium carbonate, dicalcium phosphate, salt, L-lysine-HCl, and DL-methionine. Variables observed were physical quality (pH, water holding capacity, cooking lose, and tenderness) and sensory quality. Data regarding physical quality were statistically analyzed by one-way ANOVA followed by the orthogonal contrast for significant results, and data of sensory quality by non-parametric methods such as the Hedonic Kruskal-Wallis test. The results showed that the physical quality of meat had no effect (P>0.05), except the significant water holding capacity (P<0.05) which was lower with phytobiotic extract supplementation. All sensory test parameters in fresh and cooked meat had no effect (P>0.05) following phytobiotic extract supplementation, except for the color and acceptability (P <0.05) in fresh broiler meat. The conclusion of the research was that 2.5% TE, 2.0% GE and 2.5% TGE is capable of acting as a feed additive to increase the physical and sensory quality of broiler meat.
