Rearing Pelung chicken in Indonesia, in general, uses a ration with a high proportion of rice bran, even up to 60%. Considering the high contents of fiber, lignin, and phytic acid, feeding a high portion of rice bran will decrease nutrient digestibility. This study was aimed to evaluate the effect of lime juice supplementation of a rice bran-based ration on the utilization of nutrients in male Pelung chicken. Sixty four of 12 weeks old male Pelung chickens were used in the present experiment and assigned into a completely randomized block design. The treatments were supplementation of the ration with lime juice at the levels of 0, 1, 2, and 3 mL/100 g. Parameters measured were feed and nutrients consumption, protein, fat, and fiber digestibilities, apparent metabolizable energy (AME), rate of passage, feed conversion ratio (FCR), and daily body weight gain. The results showed that the supplementation of lime juice in the ration did not affect feed and nutrient consumption, but significantly (P

The aim of study was to evaluate the effect of dietary vitamin E supplementation in Kedu and Cemani hens reraed in situ and given farmer-formulated diet on egg performances. A total of 120 female and 24 male birds were equally divided into two groups of Kedu and Cemani, with average body weight of 1890+216.79 and 1830+396.23 g, respectively. Basal ration was based on the diet formulated by the farmer (R1) consisting of corn (30%), rice bran (50%), protein concentrate (15%), and premix (5%). Dietary treatments evaluated were R1 (without additional vitamin E), and the other three were the inclusion of DL α-tocopheryl acetate into the R1 diet up to 2 (R2), 4 (R3) and 6 IU (R4). The experiment was arranged in a Randomized Block Design with 4 treatments, and 2 different groups of hen (Kedu and Cemani) were assigned as block. Parameters observed were feed consumption, hen day production, feed conversion ratio, egg quality, fertility, and hatchability. The result showed that vitamin E supplementation did not affect whatever parameters, except egg fertility. Egg hatchability between Kedu and Cemani hens was significantly different (p

EFFECT OF CRUDE FIBER ON GROWTH PERFORMANCE, VFA PRODUCTION AND VFA ABSORBTION OF TEGAL DUCK ABSTRACT The objective of this research was to evaluate the effect of crude fiber on growth performance, production and absorption of VFA on Tegal duck. Material in this research was day old duck. This research was designed following completely randomized design of one-way pattern. Treatments were level of crude fiber at 5, 10 and 15% of ration dry matter. Data were analyzed with analysis of variance and when there was an effect of treatments, then it was continued by Duncan multiple range test. Result of this research showed that the treatments did not significantly effect diet consumption (P1 = 71,53, P2 = 69,54 and P3 = 66,19 g/day) and growth performance (P1 = 19,75, P2 = 19,07 and P3 = 18,83 g/day). Levels of crude fiber in duck rations did not significantly influence the VFA production (P1 = 1019,98, P2 = 1053,21 dan P3 = 1103,18 ?mol/l) and VFA absorption (P1 = 230,15 , P2 = 251,97 and P3 = 266,17 ?mol/l.). It can be concluded that the level of crude fiber up to 15% can be tolerated by Tegal duck without influencing the diet consumption and growth performance. Crude fiber 15% did not increase VFA production and absorption VFA. 1) Staf Pengajar Jurusan Nutrisi dan Makanan Ternak, Fapet, UNDIP 2) Mahasiswa Jurusan Nutrisi dan Makanan Ternak, Fapet, UNDIP
