Effect of prebiotic oligosaccharide extract rumbia fruit (Metroxylon sago Rottb.) in the ration on broiler performanceABSTRACT. Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Prebiotic oligosaccharides are defined as nondigestible food ingredients that provide beneficial effects to the host by stimulating the growth of selected microbial members of the gastrointestinal tract. Among the colonic bacteria capable of metabolizing prebiotic oligosaccharides and whose growth is stimulated are species of Lactobacillus and Bifidobacterium. Prebiotic oligosaccharides can be produced in transgli-cosylation reactions catalyzed by glycosidases. Glycosidases from different biological sources have specific ability to catalyze the formation of oligosaccharides with particular chain lengths (usually DP 7) and predominant glycosidic linkages. Oligosaccharide used this research was purified rumbia fruit extract as prebiotic for feed additive in the ration on broiler. The objectives of this research were to study the performance of broiler given of prebiotic oligosaccharide extract rumbia fruit (metroxylon sago Rottb.) in the ration. Two hundred day-old chicks of broiler were divided into three dietary treatments and four replications. Ration used was consisted of: R1 = basal ration (control), R2 = basal ration + 0,4% oligosaccharide extract rumbia fruit, and R3 = basal ration + 0,4% frukto-oligosaccharide (FOS). The variables observed were: feed consumption, body weight, feed conversion ratio, mortality, and production index. The result showed that the performances of the broiler supplemented prebiotic oligosaccharide extract rumbia fruit (R2) was significantly (P 0.05) differences between of feed consumption, body weight, and mortality. It is concluded that of prebiotic oligosaccharide extract rumbia fruit were able to decrease the mortality and feed consumption at six week of age.

This research was conducted to determine the impact of substituting commercial feed with agroindustrial by-product feed on the growth performance of pigs in the grower phase and the benefits obtained by farmers. A total of 20 pigs aged 18 weeks were tested in a randomized block design with four treatments and five replications. The feed treatments were P0= commercial feed (CP 552), P1= 50% CP552 and 50% agroindustry feed, P2= 100% agroindustry feed, and P3= P2 feed with the addition of phytase and mannase enzymes. The results showed that feed consumption, body weight gain, and feed conversion were not significantly different among the treatments. The digestibility of the P0 was significantly higher than that of P1, P2, and P3 (p<0.05). The digestibility of the P3 was not significantly different from that of the P1; however, it was significantly higher than P2 (p<0.05). The IOFC of P2 was higher than P0 and P1, while P3 resulted in the highest IOFC among treatments. It can be concluded that utilizing feed containing agro-industrial by-products could substitute 100% of commercial feed in growing pigs and provides 60% higher income than commercial feed. Moreover, additional phytase and mannase enzymes on agroindustrial by-products feed might provide 89% higher income than commercial feed. Key words: agroindustry, by-products, commercial feed, pigs, substitution

The content of active compounds in natural materials is generally low and highly variable, thus requiring efficient and selective extraction methods. This study aims to evaluate a stepwise extraction process applied to the seeds, oil, and by-products of Nigella sativa (black cumin) to obtain thymoquinone (TQ) and other phytochemicals. The study consisted of four main stages: (1) extraction of HS oil using the cold press method, (2) stepwise extraction using 70% ethanol as solvent, (3) analysis of TQ content and phytochemical compounds in the extracts, and (4) evaluation of the antibacterial activity of habbatussauda oil extracts against pathogenic and non-pathogenic bacteria. Results showed that the cold press method yielded 34.46% oil. Stepwise extraction using 70% ethanol resulted in significant differences (p<0.05) in both yield and TQ content among the seed, oil, and by-product extracts. Among all samples, the ethanol extract from habbatussauda oil exhibited the highest yield and TQ concentration. Furthermore, at a concentration of 100 μg mL⁻¹, this extract inhibited the growth of pathogenic bacteria such as Salmonella typhimurium and Escherichia coli, without affecting non-pathogenic strains like Lactobacillus spp. and Bifidobacteria spp. In conclusion, stepwise extraction using 70% ethanol proved effective in enhancing TQ recovery and demonstrated potential as a phytobiotic agent with selective antibacterial activity against pathogenic bacteria.

The growth rate of chickens can be improved by using probiotics as alternatives to antibiotics. Bacillus spp. as probiotics are particularly beneficial due to ability to form spores, which remain stable as commercial products over extended periods. This study aimed to isolate and select Bacillus spp. from Jasinga soil as probiotic candidates for chickens. A total of 15 isolates obtained of these, 12 were identified as Bacillus spp based on microscopic observations and screening test including ascertaining hemolysis, protease, amylase, and cellulase activities. Only six isolates exhibited gamma hemolysis and the ability to hydrolyze proteins, starch, and cellulose. Isolates BTJ1.1, 1.2, 1.4, and 2.3 poliferated in 0.3% bile salts. BTJ1.1, 1.2 and 2.3 also exhibited antimicrobial activity and sensitivity to amoxicillin, tetracycline, and rifampicin. BTJ1.1 and 2.3 were highly hydrophobic, a key probiotic trait. 16S rRNA gene sequence analysis revealed that BTJ1.1 and 2.3 were >99% similar to B. amyloliquefaciens strain B54 and B. subtilis strain ASI3, respectively, highlighting their potential as probiotics.

The use of Antibiotic Growth Promoters (AGPs) in the poultry industry led to farmers’ dependence on antibiotics. Therefore, a safer alternative feed additive, such as fulvic acid, was needed. This study aimed to evaluate the effectiveness of fulvic acid extracted from oil palm empty fruit bunches (FA-OPEFB) as a feed additive on broiler chickens’ digestive tract and intestinal morphology. A total of 150 broiler chickens were used in a Completely Randomized Design (CRD) consisting of three treatments and five replications: P0 (drinking water without FA-OPEFB), P1 (drinking water with 0.1% FA-OPEFB), and P2 (drinking water with 0.2% FA-OPEFB). Observed variables included the relative weight and length of the digestive tract and intestinal morphology. The results showed that the addition of FA-OPEFB in drinking water significantly affected the ileum percentage, villus height, crypt depth, and villus surface area. It was concluded that 0.2% FA-OPEFB in drinking water reduced the relative weight and length of the ileum and improved intestinal morphology in broiler chickens. Key words: broiler chicken, digestive tract, fulvic acid, intestinal morphology, OPEFB
