Catechins are secondary metabolites compound of flavonoids group that is naturally produced by plants and have health benefits as cholesterol-lowering, antioxidant, antimicrobial in mice.Rapid growth in broilers is often followed by high-fat growth as well, thus causing a high cholesterol content in the broiler's meat especially in thigh meatand wings.Feeding extract catechin in broiler as feed additive will reduce cholesterol or fat in broiler's meat. The catechins could be extracted by maceration method, so far there is no information about the type of solvent and extraction method for extraction of catechin from Areca catechu peel. The aims of this study to obtain the best combination of solvent type and maceration duration in extracting of catechins from betel nut peel. Areca catechu peel used in this study is a green-colored fruit peel, which washarvested from betel nut seeds in Batu Balang village,

This study was performed to evaluate the effect of inclusion of boiled tomato waste powder in laying hens diet on growth performances and egg quality. Tomato waste used in this experiment was surplus and unsold mature tomato from the last harvest on the field. The tomato waste was boiled in boiling water (100 ºC) for 8 minutes to convert their lycopene structure from trans to cis, which is easily absorbed by the poultry digestive tract. In a completely randomized design, 200 Isa Brown laying hens were divided into five groups with different inclusion levels of boiled tomato waste powder (0, 3, 6, 9 and 12%) in an iso-nitrogenous (16%) and iso-caloric (2600 kcal/kg) diet. Daily feed intake, hen day egg production, egg weight, egg mass, feed conversion ratio, eggshell thickness, and eggshell strength were measured. The obtained results showed that boiled tomato waste powder in the diet did not significantly affect daily feed intake, feed conversion ratio, egg production and egg quality. In conclusion, the tomato boiled powder could be used up to 12% in laying hens diet with no effect on performance and egg quality of laying hens.
