The birds were randomly assigned to four treatments, and their body weight, weight development, feed consumption, feed conversion efficiency, dressing percentage, livability rates, and income over feed and chick cost were measured. The results showed a significant interaction between the breed of chicken and the type of probiotics after 21 days of feeding in terms of body weight, body weight gain, feed consumption, and feed conversion efficiency. However, no significant interaction was observed at 35 days of feeding. The use of locally produced probiotics in drinking water improved the dressing percentage of both breeds of chicken, overall body weight gain, and overall feed consumption compared to the control group. Livability rates were not significantly affected by the inclusion of different locally-made probiotics in drinking water. Net income per chicken was marginally higher for the chickens fed with locally produced probiotics. Further studies are recommended to assess the benefits of locally-produced probiotics in laying chicken and other types of livestock and poultry. These findings provide insights into the potential application of locally-made probiotics as an alternative to commercial products for improving chicken performance.","PeriodicalId":30622,"journal":{"name":"Biosaintifika Journal of Biology Biology Education","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135875904","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}

The objectives of this study were to detect and characterize the Cymbidium mosaic virus (CymMV) from the native orchids of South Kalimantan, Indonesia, by the RT-PCR method. Also, to determine their phylogenetic relationship based on a partial genome of RdRp by the ML and PCA methods. Following RT-PCR analysis, one of 10 samples of native orchids used was positively infected by CymMV. In early detection, the RdRp region of CymMV has approximately 530 bp in size. After being sequenced and aligned with other isolates, this region has 121 polymorphic or mutation sites, a GC content of 45.21%, a transition/transversion bias value of 3.52, and nucleotide diversity (0.0415). The phylogenetic analysis revealed that CymMV from South Kalimantan, Indonesia, has closest related to similar isolates from Korea Type 2 (AF016914.1), Niigata, Japan (AB197937.1), Hawaii (EF125180.1), and Taiwan M2 (EU314803.1), with the coefficient divergence of 0.025. But, it has very distantly related to Hawaii 18-1 (EF125178.1) with a coefficient of 0.142.

These natural compounds are biosynthetic products of symbiont bacteria from various phyla colonizing sponge tissue. Some symbiont bacteria are known to produce bioactive compounds that would have antibacterial activity, such as polyketide, due to competition in colonizing and obtaining nutrients from their hosts. In general, this study aims to explore the biosynthetic potential of seven sponge-symbiont bacteria by detecting the gene domain involved in the production of polyketide compounds. Sponge-symbiont bacteria isolation was carried out on one species of sponge collected from a depth of ±15 m in the Iboih area, Weh Island, Aceh Province, Indonesia. The bacteria was allowed to grow in Sea Water Complete agar medium and incubated at 280C for 10-14 days. The production of polyketide compounds involves the enzyme polyketide synthase (PKS). Polyketide synthase was detected by detecting the encoding gene domain involved in the production of polyketide compounds using PCR method. Five of the seven isolates of sponge symbiont bacteria were detected to contain the PKS gene domain. Furthermore, molecular identification confirm by 16S rRNA sequencing showed that the isolates belonged to the phylum Firmicutes and Actinobacteria. The result indicated that the sponge symbiont bacteria collected from Weh Island had the biosynthetic potential to produce polyketide compounds. These compounds would have antimicrobial activities that will play a major role in the medical field.
