Sentul chicken is a specific local chicken from the Ciamis region in West Java and a dual-purpose type that can be utilized for eggs and meat production. The use of antibiotics continuously for maintenance to prevent and treat disease in Sentul chicken can lead residues in meat and eggs. To wean farmers for the antibiotic, it is necessary to find a natural antibiotic derived from herbal plants that Mangosteen Peel Extract (MPE). Mangosteen Peel Extract (MPE) is containing xanthone compounds like antioxidants and antimicrobials. This research was held to find out the effect of mangosteen peel extract on feed consumption, hen day production, feed conversion, and egg quality. This research used 40 female chickens aged seven months, which was kept in cages until three months, and each cage contains 2 chickens. The method used was a completely randomized design with four treatments namely P0 (ration without MPE), P1 (ration with 67 ml/kg MPE addition), P2 (addition of 100 ml/kg MPE) and P3 (addition of 133 ml/kg MPE) with five replications. Furthermore, treatment differences were tested using Duncan Multiple Range Test. The measured variables were feed consumption, egg weight, hen day production, feed conversion, thick of shell, egg yolk color, and egg cholesterol. The results showed the addition of MPE 133 ml/kg ration had a significant effect on egg production, egg weight, feed conversion, the thickness of eggshell, the color of egg yolk, and egg cholesterol but not significant to feed consumption, yolk index score and Haugh unit. It can be concluded that MPE can be used as a feed additive until 133 ml/kg ration to gave the best on production and egg quality of Sentul chicken.
Nutritional Balance in feed is critical to improve the efficiency of feed. The use of oil in omnivore fish can serve as a spare protein-energy provider in addition to carbohydrates. Not only is the adequacy of the quantity and quality of protein that must be guaranteed, often the energy value is not as predicted, so the addition of high-calorie ingredients is important. Efforts to replace some of the protein functions as an energy source, by feed oil supplements from pairing coconut flesh as saturated fat combined with candlenuts as unsaturated fat, with added of trace element Se, thus improving the optimum use of protein in freshwater fish.This study aims toget the ratio and type of fat (saturated and unsaturated) of feed formula (low protein 28%) with selenium supplementation, compared with high protein (32%), which can increase feed efficiency of red nile tilapia (Oreochromis niloticus) fingerling phase. The preparation stage found that pairing coconut fat supplements were dominated by saturated fatty acid as lauric (42.67%). In contrast, candlenut fats contained unsaturated fatty acids, linoleic (34.4%), and oleic (48.99%), so the use of candlenut oil (0%, 2% and 4%) can increase the ratio of unsaturated fatty acids in the feed. Treatments consist of 6x3 with Completely Randomized Design by a ratio of the source of unsaturated fat and saturated fat with mineral addition Se. R1was low protein feed without supplements; R2 and R3were low protein feed containing ratio of unsaturated-saturated fat 1:1 (mixture of oil were 2% of each) without and with addition of Se, and then R4 1:2 (coconut oil); 2:1 (candlenut oil) and R6 high protein without of fat supplements 2:3, produces normal physiological (hematologic and digestive) images for tilapia health.The Result showed that coconut and candlenut mixed-oil 2% of each with addition of Se 0.15 ppm, was the best feed efficiency in tilapia ranged from 50.14-57.93% and protein efficiency ratio 1.72 -2.06.
Physical characteristics pelleted non-extrusion containing bioprocess product of coconut husk, has been investigated. The study was designed experimentally using a Completely Randomized Design (CRD), five treatments were repeated three times. Five treatments included the use of bioprocess product of coconut husk fermentation (CHF) as much as 0%, 25%, 50% and 75% as substitution of conventional raw material energy source on pelleted formulation, and control (floating pellet). The parameters measured were sink speed test, durability test, stability test and moisture content test. The effect of each treatment on parameters was analyzed using Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Distance Test. The results showed that bioprocess did not show a significant difference on durability, but product of coconut husk additive feed increased stability of ration water, breaking speed and sinking speed. Stability of ration water with the addition of coconut husk fermentation 75% CHF was significantly higher than other CHF treatments, but not significant different with control pelleted. Stability of ration water in 25-75% CHF treatments. after 120 minutes ranging from 75.93% -81.77%, with pellet durability of 93.33-98.84%.
