Effects of Soluble and Insoluble Non-Starch Polysaccharides on Growth Performance, Digestive Enzyme Activity, Antioxidant Capacity, and Intestinal Flora of Juvenile Genetic of Improvement of Farmed Tilapia (Oreochromis niloticus)

This study aimed to evaluate the effects of soluble and insoluble non-starch polysaccharides (NSPs) on growth performance, digestive enzyme activity, antioxidant capacity, intestinal flora juvenile GIFT tilapia ( Oreochromis niloticus ). Four isonitrogenous isolipidic experimental diets were formulated, including FM diet (0% NSPs, FM), INSP (5.8% INSP), SNSP (12.2% SNSP), NSP 12.2% SNSP, NSPs). Each was fed triplicate groups 40 fish (2.14 ± 0.04 g) per repetition for 10 weeks. Results showed that dietary supplementation with different types NSPs significantly affected tilapia. Specifically, increased pepsin lipase while decreased activity resulted in a significant decrease plasma catalase, glutathione peroxidase, total capacity activity. Meanwhile, concentration urea nitrogen high-density lipoprotein cholesterol alanine aminotransferase hepatic. Moreover, LEfSe analysis abundance Bacteroidales , Bacteroidia Cellulosilyticum Mycobacteriaceae Mycobacterium_neoaurum Corynebacteriales Mycobacterium . These results suggest is an inert ingredient limited effect, inhabited induced liver damage, altered anaerobic/aerobic bacteria intestine
