dc.description.abstractDisease has been considered one of the most significant concern for the sustainable development of striped catfish, Pangasianodon hypophthalmus, therefore, a series of experiments were carried out to determine the most suitable level of probiotic Lactobacillus acidophilus (LAB) and prebiotic mannaan oligosaccharide (MOS), respectively, that can promote growth and improve the health status of e striped catfish. Triplicate groups of e striped catfish (initial weight 21.69±0.18 g) were fed twice daily at 2.5% of body weight, with 0 (control), 103, 105, 107 and 109 CFU/g LAB diets, for 12 weeks. Results revealed that the growth performance and health status based on haematology and immunological parameters were significantly improved when fish were fed the diet supplemented with 105CFU/g and above LAB. In another study under similar experimental conditions, when striped catfish (20.41±1.64g) were fed with five experimental diets containing 0 (Control), 0.2%, 0.4%, 0.6% and 0.8% MOS, respectively, the growth performance and health status were significantly improved for 0.6% MOS diet fed group than the control fed group. The effect of LAB or MOS supplementation on diet digestibility and subsequently the growth and health status, were evaluated by feeding fish (20.50±0.28 g) with test diets in which 45% of fish meal protein was replaced with soybean meal protein. Although feeding fish with the LAB or MOS supplemented in the diets containing SBM did not improve the growth performance and nutrient digestibility, the health status of striped catfish was significantly improved by increasing the haematological parameters, total immunoglobulin content and lysozyme activity. Based on the results of all the studies, it can be concluded that supplementation with 105 CFU/g of LAB and 0.6% MOS is sufficient to improve growth and health status of e striped catfish when they were exposed to A. hydrophila CT19. Further, supplementation of a soybean based diet containing 55% protein from FM and 45% protein from soybean meal with 105 CFU LAB or 0.6 % MOS, improves the health status of P. hypopthalmus es without compromising growth and nutrient digestibility.en_US
