Abstract
Owing to their availability, cost effectiveness and environmental-friendly nature, plant extracts are promising additives for fish farming. This study aims to determine the optimal dosage of fermented herbal extract (FHE)-composed of Morus alba (33.3%), Curcuma xanthorrhiza (33.3%), and Boesenbergia rotunda (33.3%)-for growth enhancement and feed utilisation efficiency of Oreochromis niloticus fingerlings. Fermentation was conducted using probiotics Lactobacillus casei (Yakult®, Tokyo, Japan) and Saccharomyces cereviceae (commercial baker's yeast). The FHE was high in flavonoid and alkaloid, vitamin C, potassium, natrium, lipase and protease. Four doses of FHE treatments, namely treatment A (0 mg/kg of feed); treatment B (100 mg/kg of feed); treatment C (300 mg/kg of feed); treatment D (500 mg/kg of feed) were compared. After subjected to 35 days of culture, tilapias subjected to FHE-coated feed exhibited better weight gain (WG), specific growth rate (SGR), and feed efficiency (FE) compared to control. The best dosage that gave the highest growth and feed efficiency was treatment C (300 mg/kg of feed). Furthermore, the feed efficiencies of FHE-incorporated treatments were positively influenced by the increased in length and density of intestinal villi, number of goblet cells, lymphocytes, as well as nutrient retention to support growth. The results of this study indicate that FHE is a promising functional feed additive to stimulate growth and improve feed efficiency in tilapia farming.
期刊介绍:
Tropical Life Sciences Research (TLSR) formerly known as Journal of Bioscience seeks to publish relevant ideas and knowledge addressing vital life sciences issues in the tropical region. The Journal’s scope is interdisciplinary in nature and covers any aspects related to issues on life sciences especially from the field of biochemistry, microbiology, biotechnology and animal, plant, environmental, biomedical and pharmaceutical sciences. TLSR practices double blind peer review system to ensure and maintain the good quality of articles published in this journal. Two issues are published annually in printed and electronic form. TLSR also accepts review articles, experimental papers and short communications. The Chief Editor would like to invite researchers to use this journal as a mean to rapidly promote their research findings.
