Black Soldier Fly Larvae (BSFL) is an alternative protein source for livestock. This research aimed to know the effectiveness of BSFL for commercial feed substitution, related to production, productivity, and profitability in quail farm. This study used 80 quails which divided into 4 groups and each group consist of 20 quails. The treatments contained BSFL substitution with different composition, control group (P0) was given 100% commercial feed, (P1) was given a 5% BSFL substitution, (P2) was given a 10% BSFL substitution and (P3) was given a 20% BSFL substitution. Contribution margin (CM) analysis was used to determine the yields of the groups in this study. Results showed that the highest feed consumption rate is in P3, production (egg in total and weight), productivity and yields in P3 is the highest, although there's no difference between P0, P2 and P3 based on the analysis MANOVA. BSFL substitution at 20% is recommended to the farmers to increase profits.
Fibrosis hati merupakan akumulasi berlebih matriks ekstraseluler. Prevalensi fibrosis hati hewan kecil dilaporkan mencapai 10% dari keseluruhan penyakit sistemik hewan kecil di Amerika Serikat. Salah satu bahan toksik yang menimbulkan fibrosis hati adalah carbon tetrachloride (CCl4). Penelitian ini bertujuan untuk mengetahui pengaruh preventif ekstrak etanol daun jambu mete (Anacardium occidentale) terhadap produksi Interleukin-6 (IL-6) dan kadar superoxide dismutase (SOD). Daun jambu mete mengandung bahan aktif flavonoid yang memiliki efek antiinflamasi dan antioksidan. Penelitian ini merupakan studi eksperimental, post-test control only design dengan menggunakan Rancangan Acak Lengkap. Hewan coba mencit (Mus musculus) dibagi dalam 5 kelompok perlakuan, yaitu kelompok kontrol negatif, kontrol positif, kelompok preventif dengan dosis 500 mg/kg BB, 1000 mg/kg BB, dan 1500 mg/kg BB. Produksi sitokin IL-6 dihitung menggunakan metode flowcytometry, sedangkan kadar SOD diukur menggunakan spektofotometri. Data hasil uji dianalisa secara statistik one way ANOVA (α=0,05) dengan uji lanjutan Post Hoc Tukey. Simpulan dari penelitian ini yaitu preventif menggunakan ekstrak etanol daun jambu mete mencegah peningkatan produksi IL-6 dan meningkatkan kadar SOD pada mencit model fibrosis hati. Persentase produksi IL-6 pada kelompok perlakuan dosis 1500 mg/kg BB sebesar 2,58%. Kadar SOD pada kelompok perlakuan dosis 1500 mg/kg BB sebesar 4,23%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
