Two stages of in vitro ruminal digestibility were prepared and applied with different dietary treatments following: CON, consisted of 20% RS and 80% GC; T1, consisted of 20% RS, 70% GC, and 10% CL; T2, consisted of 20% RS, 60% GC, and 20% CL; T3, consisted of 20% RS, 50% GC and 30% CL; and T5, consisted of 20% RS, 40% GC, and 40% CL. Each dietary treatment was prepared in quadruplicate. All dietary treatments were incubated into rumen buffer along with three blanks for analysis of ruminal digestibility (in vitro first stage), and then continued into chloride acid solution with pepsin incubation for analysis of total digestibility (in vitro first and second stages). Previously, the rumen fluid was collected from two Bali steers that fed Pennisetum purpureum and commercial concentrate at 8:2 ratio. Both stages were conducted at 39C for 48 h, respectively. In the ruminal digestibility, an increasing ratio of CL was reported to decrease (P<0.05) dry matter digestibility (DMD) and organic matter digestibility (OMD) of diet. Digestibility of crude protein (CPD) in the rumen was highest (P<0.05) in dietary T3, followed by dietary T2, dietary T1, and then dietary T3 and T4, consecutively. Supported with results of ruminal digestibility, an increasing ratio of CL also decreased (P<0.05) DMD and OMD of diet in the total digestibility. Moreover, it also decreased (P<0.05) CPD of diet in the total digestibility. Therefore, the present study concluded that dietary treatment consisting of 70% GC and 10% CL with 20% RS presented the most optimum ratio resulting the highest digestibility through in vitro technique.","PeriodicalId":7202,"journal":{"name":"Advances in Biological Sciences Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89876930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One source of natural medicine is honey and propolis of stingless bees. Efficacy physical and chemical properties of honey are influenced by the type of pollen and the environment, while geological factors influence the composition of propolis. Bee and stingless bee colonies have a behavior called feed preference. This preference is influenced by several aspects, such as food source location and the selected plant species that produce pollen, nectar, and resins. Therefore, this research was conducted to study the diversity of pollen and the composition of propolis bioactive compounds of stingless bees from Kedungpoh Meliponiculture in Gunungkidul, Yogyakarta. Identification of bees was carried out using a Digital Microscope Super eye . Pollen preparation was made using a modified acetolysis method and observed under a light microscope. The competition of bioactive compounds of propolis was investigated by GC-MS, Gas Chromatograph-Mass Spectrometry. The results showed the diversity of pollen of stingless bees ( T. laeviceps) from Kedungpoh Meliponiculture in Gunungkidul, Yogyakarta was from various plants belonging to 27 families consisting of herbs, shrubs, and trees. The dominated pollen family was from Arecaceae, 26,00 % of the total amounts of pollen. GC-MS result showed that the propolis was composed of 42 types o f t h e bioactive compound and grouped into four categories: terpenoid (62,50%), phenolic (29,22%), steroid (7.08%), fatty acid (1,20%). The most dominant bioactive compound was (Z)-3-(pentadec-8-en-1- yl) phenol (C 21 H 34 O) (23.32%) from the phenolic group.","PeriodicalId":7202,"journal":{"name":"Advances in Biological Sciences Research","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73522744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water hyacinth (Eichhornia crassipes) leaf has a chemical composition similar to rice bran and its availability is abundant but its quality as feed material for poultry is also low because of the high content of the fiber. Some studies showed that fermentation could improve the nutrient content of feedstuffs. A study was conducted to evaluate the efficacy of fermentation using two different cultures incubated for 0, 7, 14, and 21 days. The results showed that protein contents did not differ significantly between the two microbial cultures, but the mixture of rice bran and water hyacinth leaves fermented using a culture containing 5 types of microbes resulted in lower fiber content. The duration of incubation significantly affected both the fiber and protein content. It was concluded that the nutrient content of the mixture of rice bran and water hyacinth leaves could be improved by fermentation using a microbial mixture for 14 days.","PeriodicalId":7202,"journal":{"name":"Advances in Biological Sciences Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75553191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
