Natural feed additive supplementation could lead to higher production performance of quails on many occasions. This study was aimed to evaluate the effect of Piper betle L. (betel leaf) infuse supplementation on egg characteristics of quails. Quails were raised in Slamet Quail Farm, Sukabumi, West Java, Indonesia for 3 months. Quails had been fed adlibtum using a commercial diet. Betel leaf supplementation in different concentration had been given to replace drinking water. The treatments were P0: 0% supplementation, P1: 10% supplementation was given since day old quail (DOQ), P2: 20% supplementation was given since DOQ, P3: 30% supplementation was given since DOQ, P4: 10% supplementation was given since laying phase, P5: 20% supplementation was given since laying phase, P6: 30% supplementation was given since laying phase. The results showed that betel leaf infuse supplementation reduced the weight of egg shell, increasing the weight of egg albumin and increased egg weight significantly (P<0.05). There was no significant effect (P>0.05) on another egg quality variables. It could be concluded that betel leaf infuses supplementation could affect the egg shell, albumin, and egg weight without affecting other egg quality traits. Overall, betel leaf supplementation could be applicated because it could increase egg albumin quality and egg weight. Even though additional handling is needed because betle leaf infuses supplementation could reduce egg shell quality and the egg could break easily.

One disadvantage of crude palm oil (CPO) as a feedstuff is its property of rapidly being rancid, and thus could decrease quality and palatability of ration. To over come the problem, an antioxidant is needed to prevent lipid deterioration. The aim of this research was to prevent lipid deterioration in broiler ration containing CPO using garlic and cumin as antioxidants. The experimental run in a factorial arrangement according to completely randomized design with 2 factors and 3 replications for each treatment combination. The first factors were either A1= control ration, A2= control ration + 0.2% garlic, A3= control ration + 0.4% garlic, A4= control ration + 0.6% garlic, A5= control ration + 0.02% BHT or B1= control ration, B2= control ration + 0.2% cumin, B3= control ration + 0.4% cumin, B4= control ration + 0.6% cumin, B5= control ration + 0.02% BHT. Butyl hidroksitoluena (BHT) is a synthetic antioxidant. The second factors were duration of storage, i.e. P1= 0 week, P2= 2 weeks, P3= 4 weeks. Parameters observed were water content, fat content and free fatty acid content of the ration. The results of the experiment indicated that use of both antioxidant garlic and cumin decreased (P<0.05) free fatty acid content and fat content, but the former did not affect water content as the later did. The best ration was ration containing either 0.6% garlic or 0.4% cumin as an antioxidant which was indicated by a decrease in free fatty acid and lipid contents so that could slow down lipid deterioration in the ration. Use of garlic 0.6% or cumin 0.4% was better compared with the use of BHT 0.02%. Results also indicated that storage time affected (P<0.01) parameters in terms of increasing water content, free fatty acid content, and decreasing fat content

The effect of different water spraying level and storage period on endurance of pellet broiler finisherABSTRACT. The storage is very important in a farm management, because this activity can take care of feed stability which enough and preferable to be consumed by animal and also strive for animal food availability continuously. The purpose of this research is to know the water spraying level and variation of storage period against the endurance of pellet broiler finisher ration. This research was designed by a Completely Randomized Design Factorial with two factors (water spraying different level and storage period) with four replicates, the significant result were analyzed by orthogonal contras test. On this experiment, the different level of water spraying (0, 3, 6%) were conducted during mixing at conditioning process, and then the ration were stored until four weeks to study the endurance of pellet e.g.: water content (%), water activity, specific gravity (ton/m3), pellet durability index (%), attack of insect. The water content, specific gravity, and pellet durability index was very significantly (P0.01) reduce by water spraying different level, and not significantly on water activity. The storage period showed very significantly (P0.01) increase the specific gravity, pellet durability index, and the insect attacks, and significantly (P0.01) decreased the water activity, but not effect on water content. Interaction among spraying level and storage period is very significantly (P0.01) on the values of water content, water activity, specific gravity and pellet durability.

The effect of reduction of maize as starch source on flow rate of pellet in continuous production processABSTRACT. This experience was conducted to determine effect of reduction of maize as starch source on flow rate of pellet in continuous production process. Design of the experiment used was a completely randomized design with 3 treatments and 3 replicates. The data is analyzed by using of ANOVA and if there is a significance among treatments would tested using by contrast orthogonal. The variables observed were angle of repose, loose bulk density, compacted bulk density, and flow rate. The results showed that the reduction of maize as starch source did not give the significant effect on the variable that observed. The analyzed angle of repose showed variation 24.200 to 25.690, loose bulk density showed variation 621.6kg/m3 to 658kg/m3, compacted bulk density showed variation 668.3kg/m3 to 676.8kg/m3, and flow rate showed variation 449.69kg/minute to 491.41kg/minute. Based on the result that the reduction of maize as starch source (corn, sorghum, menir) did not give the significant effect on flow rate of pellet and the pellet treatment with menir has the fastest pellet production time so flowability pellet from pelleter to material hadling (bucket elevator) machine is faster. As higher the values of flow rate, so the time of material movement from bin to the package is shorter.
