EVALUATION OF PHYTOCHEMICAL COMPOUNDS, ANTIOXIDANT AND ANTIBACTERIAL ACTIVITY ON RED FRUIT PEEL AS FEED ADDITIVES
No full textABSTRAKRed fruit (Pandanus conoideus Lamk) is a native plant from Papua that contains many bioactive compounds such as tocopherol, alpha tocopherol, carotenoids, and flavonoids as well as phenolic, which are potential as antioxidant and antibacterial agents. Red fruit also contains unsaturated fatty acid especially oleic acid (omega-9) which is useful for improving nutritional status of the community along with its mineral contents of Fe, Ca and Zn. The results of this study showed that red fruit peel contains phenolic and flavonoid compounds with test results of 652,49 mg GAE/100g and 143,08 mg/100g respectively. Red fruit peel has antioxidant activity with IC50 value of 75,785 µg/gr. Antibacterial activity of red fruit peel has a weak inhibition zone but significantly have a good inhibition to Escherichia coli, Salmonella typhi and Lactobacillus plantarum bacteria (P <0,01).Key words: Red fruit peel, phenolic, flavonoid, antioxidant activity, antibacterial activity

Meat and Bone Ratio of Broiler Fed with Different Proportions of Fish Meal
No full textThis study aims to determine the ratio of meat and bones of broiler fed a diet containing fish meal with different proportions. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 4 replicates and each replication consisted of 6 chickens. The treatment used was commercial feed BP-11 as control feed (P0), 43% corn + 21% rice bran + 27% CAB Concentrate + 9% fish meal (P1), 43% corn + 23% rice bran + 22% CAB Concentrate + 12% fish meal (P2), dan 43% corn + 25% rice bran + 17% CAB Concentrate + 15% fish meal (P3). The variables measured in this study were the percentage of meat weight, the percentage of bone weight, and the ratio of meat and bones of broiler. The data obtained were analyzed by variance analysis and the treatment that affected the measured variables was further tested using Duncan's Multiple Range Test. The results showed that the average percentage of broiler meat in this study was 67.26% (P0), 68.71% (P1), 69.36% (P2) and 70.23% (P3). The averages of bone percentages were 23.18% (P0), 25.53% (P1), 22.48% (P2) and 22.58% (P3). Meanwhile, the ratio of meat and bones were 2.92% (P0), 2.79% (P1), 3.09% (P2), 3.20% (P3). The results of the analysis of variance showed that the treatment had no effect on the percentage of meat, the percentage of bone and the meat-bone ratio. It was concluded that the addition of fish meal up to 15% into diet had no significant effect on percentages of meat and bone, and the ratio of meat to bone.Keywords: broiler, fish meal, meat, bone, rati
The Potency Of Glutamate Producing Lactic Acid Bacteria Isolated as Additive Feed In Improving Broiler Performance
No full textABSTRACT
Glutamate is one of the amino acids that can act as flavor neurotransmitter. Some lactic acid bacteria (LAB) are known as producers of glutamate. Such LAB could be widely found in many fermentation products. The objectives of this study were to isolate and characterize some glutamate producing LAB isolated from West Sumatera fermented food products (dadih, asam durian, ikan budu and tapai). A total of 1,014 LAB was isolated from the fermented food products. Of these, 40 isolates were considered the best based on their ability to produce inhibition zones >2mm in the presence of 2% CaCO3. Qualitative analysis using thin layer chromatography and quantitative analysis using spectrophotometer revealed that 27 of the 40 LAB isolates produce glutamate. The highest glutamate production was found in LAB of dadih origin (coded as N32). N32 produced a glutamate of 38.25 mg/ml. N32 was found to be gram positive, negative for catalase, oxidase and motility, and can utilize sugars in the form of lactose, glucose and mannitol. The N32 was identified to be Lactobacullus sp. Thus N32 (Lactobacullus sp) from dadih has the potential to produce glutamate acid.

Leukocyte Profile of Dexamethasone-Induced Quail After Administration of Bombyx Mori Silkworm Pupae Extract
No full textPoultry especially Japanese quails are susceptible to the environmental threat that induced glucocorticoid hormone secretion. Glucocorticoids stimulate oxidative stress and a decrease in the immune system. The purpose of this research is to study the potential of silkworm extract (Bombyx mori) to overcome oxidative stress and reduced the immune system in quails that were induced with dexamethasone as glucocorticoid. Thirty-two adult quails were used and were given dexamethasone. Those quails were divided into 4 groups, four groups were given 0 mg, 0.16 mg/kg, 0.32 mg/kg, and 0.64 mg/kg of silkworm extract for each quail. The parameters that were observed are total leucocyte count, differential leucocyte count, and heterophil/lymphocyte ratio. The results are not significant compared to the groups that were not given any supplements. This study shows that the administration of silkworm extract is not effective for recovery purposes.Keywords: antioxidant, quail, Bombyx mori, dexamethason
Profile and Income of Bali Cattle Farmers under Different Farming Systems in Southeast Sulawesi, Indonesia
No full textThe farmers in Southeast Sulawesi, Indonesia have started using the intensive farming system for Bali Cattle rearing in recent decades. This study aimed to determine the profile and income of Bali Cattle farmers under intensive, semi-intensive, and extensive farming systems in Southeast Sulawesi, Indonesia. The research was conducted using the Participatory Rural Appraisal (PRA) method. Profile and income data were collected from 105 farmers selected by purposive sampling. The analytical model used is one-way ANOVA with the farming system as a factor. The results showed that the age of intensive farmers was younger (p<0.05) and had a lower experience of raising livestock (p<0.05) than extensive and semi-intensive farmers. In addition, farmers in the intensive farming system have a higher goal of raising livestock as fertilizer producers (p<0.05) than extensive and semi-intensive. However, semi-intensive and extensive farming systems had a higher average number of cows, net body weight production yield, income, and value-added (p<0.05) than the intensive farming system. Based on the results, it can be concluded that semi-intensive and extensive farming systems generate high incomes and can be more economically sustainable than intensive systems.Keywords: participatory rural appraisal, animal production system, farming syste

Use of Collagenase Enzyme as a Substitute for Trypsin on In Vitro Growth of Liver, Kidney, and Fibroblasts of Chicken Embryo Cells
No full textThis study aims to determine the effect of using the collagenase enzyme on the viability of chicken embryos' liver, kidney, and fibroblast cells in vitro. Liver and kidney organs were collected from embryonic chicken eggs at 15 and 19 days. Meanwhile, fibroblast cells were obtained using muscle tissue of 11-day-old chicken embryos. Each organ and tissue was chopped and incubated using 0.1% trypsin for 10 minutes and 0.1% collagenase for 30 minutes. Concentration, viability, and proliferation rate were calculated after incubation and analyzed using a t-test. The results showed that there was a significant increase in the tissue incubated with collagenase on the viability and proliferation rate of liver cells, kidney cells, and chicken embryo fibroblast cells (t0, 05). Cell isolation and purification techniques need to be carried out to study the quality of somatic cell culture of chicken embryos more specifically.Keywords: collagenase, trypsin, chicken embryos, viability, cell culture
