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

This study aimed to determine the effect of addition of onion skin flour (OSF) and garlic skin flour (GSF) on feed digestibility of crude protein, body weight gain and carcass percentage of Mojosari ducks. The research used 168 Mojosari duck males aged 4 weeks and had an average weight of 335.5 ± 72 g/duck (CV = 7.8%). The study used completely randomized design with7 treatments and 4 replications (T0 = basal feed (BF); T1 = BF + 3% OSF; T2 = BF+ 6% OSF; T3 = BF+ 3% GSF; T4 = BF+ 6% GSF; T5 = BF + 1.5% OSF + 1.5% GSF; and T6 = BF+ 3% OSF + 3% GSF).The results showed that the protein digestibility was found higher (P 0.05) the duck carcass percentage. The study concluded that the addition of 6% GSF and combination of 3% OSF + 3% GSF could improve crude protein digestibility and weight gain, but was not able to increase the percentage of duck carcasses.

This research aimed to investigate the effect of a symbiotic of Lactobacillus casei and garlic powder (SLG) as an antibiotic substitution on nutrient digestibility and meat production of broiler chickens. A total of 175 of 1-day-old chick were allotted to 5 dietary treatments, i.e. antibiotic, symbiotic 0,1,2 and 3%. The study was arranged with a completely randomized design. The observed variables included nutrient digestibility (protein, crude fiber, fat) and meat production. Dietary symbiotic supplementation significantly increased nutrient digestibility and meat production in broiler chickens. SLG treatment significantly affected and better than control. Protein digestibility in the antibiotic group was better than in the control group, but the same as in the symbiotic group. Meanwhile, the digestibility of crude fiber and crude fat in the antibiotic group was lower than the symbiotic group. This means that symbiotic can be used as a substitute for antibiotics. In conclusions, broilers in the SLG treatment group showed better nutrient digestibility and meat production than control. Symbiotic of Lactobacillus casei and garlic powder (SLG) can be effectively used to growth promoter in the broiler chickens.

This study was conducted to evaluate the effects of natural additives (synbiotics) made from Lactobacillus casei and dahlia tuber extracts (LDT) and synbiotics made from Lactobacillus casei and garlic tuber extract (LGT) on the number of lactic acid bacteria and coliform in the small intestine and body weight of broiler chicken. One hundred and sixty 1-day-old broilers were randomly placed in 20 experimental units for 3 weeks. The study used a completely randomized design with 5 treatments and 4 replications, each experimental unit consisted of 8 birds. The treatments tested were level of additives, T0 (control), T1 = LDT 1%, T2 = LDT 2%, T3 = LGT 1% and T4 = LGT 2%. The parameters observed were the amount of lactic acid bacteria (LAB) and coliform in the small intestine and the body weight of the starter phase of broiler chickens. The collected data were analyzed for variance and if there was a significant effect, then continued by Duncan multiple region test. The results showed that used of LDT1% and LDT 2% no significantly affected on lactic acid bacteria, coliform and body weight of broiler chickens. Giving LGT 1% and LGT 2% significantly increased the amount of LAB in the small intestine and increased body weight, while the number of coliform was significantly lower than the control. The conclusion was that the natural additives LGT 1% and 2% could increase LAB, reduce colliform and improve the performance of broiler chickens.

Onion and garlic husks contain antioxidant compounds such as allinin, allisin and flavonoid. The compounds are able to decrease fat and cholesterol levels in the body. This study was carried out to determine the effect of feeding onion husk powder (OHP) and garlic husk powder (GHP) on protein, cholesterol and fat content of Mojosari duck meat. The experiment was arranged in a completely randomized design (CRD) and used 168 birds of 4 weeks old male Mojosari ducks. The ducks were divided into 7 treatments and 4 replications (6 ducks each). The treatments were conducted for 4 weeks were as follows: T0 (control diet), T1 (control diet + 3% OHP), T2 (control diet + 6% OHP), T3 (control diet + 3% GHP), T4 (control diet + 6% GHP) and T5 (control diet + 1.5% OHP + 1.5% GHP) and T6 (control diet + 3% OHP + 3% GHP). The results showed that dietary OHP and GHP significantly increased protein and decreased cholesterol contents of duck meat, but no effect on meat fat. It could be concluded that the effect of feeding of OHP and GHP separately or in combination was able to increase protein and decrease cholesterol contents, but could not decrease fat content of Mojosari duck meat.

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.
