The effects of dietary inulin and Jerusalem artichoke (Helianthus tuberosus) tuber on the growth performance, haematological, blood chemical and immune parameters of Nile tilapia (Oreochromis niloticus) fingerlings

Abstract

This study investigated the effects of dietary inulin or Jerusalem artichoke (JA) on the growth performance, haematological, blood chemical and immune parameters of Nile tilapia fingerlings. Five treatment diets were designed to incorporate inulin at 0 (basal diet), 2.5 and 5.0 g/kg and JA at 5.0 and 10.0 g/kg. Two basal diets including fish meal and formulated experimental feed were used for fry and fingerling growing periods, respectively. During the fry growing period, larvae were fed treatment diets for 4 weeks. There were no significant differences in growth performance or survival rate. Fingerlings were then nursed with the formulated experimental diets from weeks 5 to 12. Fingerlings fed on inulin at 5.0 g/kg or JA at either level had better growth performance and survival rate than that fed on the basal diets. There were no significant differences in body composition. Dietary prebiotic inulin and JA increased red blood cell number (p < .05). Among the five blood chemistry parameters examined, both inulin at 5.0 g kg and JA (5.0 and 10.0 g/kg) increased blood protein (p < .05). Dietary inulin at 5.0 g/kg and JA at 5.0 and 10.0 g/kg increased total immunoglobulin and lysozyme activity (p < .05). Both inulin and JA inclusion diets increased alternative complement activity (p < .05). Taken together, dietary inulin at 5 g/kg and JA at 5.0 and 10.0 g/kg had beneficial effects on the growth performance, survival rate and immune of Nile tilapia fingerlings.

Effects of dietary xylooligosaccharide on growth and feeding performance, body composition and physiological responses of sobaity seabream ( Sparidentex hasta ) juvenile

“…() did not observe any differences in protein, fat and moisture of Asian seabass fed with different levels of dietary MOS after 60 days. Moreover, similar results have been reported in the other studies on some fishes such as hybrid striped bass ( Morone chrysops × Morone saxatilis ) (Burr, Hume, Ricke, Nisbet, & Gatlin, ), red drum ( Sciaenops ocellatus ) (Buentello, Neill, & Gatlin, ), gilthead seabream ( Sparus aurata ) (Dimitroglou et al., ; Gültepe, Salnur, Hoşsu, & Hisar, ), European sea bass ( Dicentrarchus labrax ) (Torrecillas et al., , ) and Nile tilapia ( Oreochromis niloticus ) (Tiengtam, Paengkoum, Sirivoharn, Phonsiri, & Boonanuntanasarn, ). In contrast to this result, the elevated carcass protein was reported in Atlantic salmon ( Salmo salar ) and Asian seabass treated with dietary MOS and inulin (Ali, Ambasankar, Nandakumar, Praveena, & Syamadayal, ; Grisdale‐Helland, Helland, & Gatlin, ).…”

“…Similarly, Li et al (2008) and Ali et al (2017a) showed that dietary 0.4 g/kg XOS and 2.5-10 g/kg FOS could increase serum complement and lysozyme activity of turbot and lysozyme activity of Asian seabass, respectively. In the present study, alternative complement activity in fish fed on 5 and 10g/kg XOS were significantly higher and lower compared to the control fish; nonetheless, the amounts of total immunoglobulin and lysozyme activity were not affected by dietary XOS, even though the amounts of these factors in the control group were slightly lower than those of XOS Hoseinifar, Merrifield, Barati, & Abadi, 2012;Tiengtam et al, 2017), inulin in gilthead seabream (Cerezuela, Cuesta, Meseguer, & Esteban, 2008) and MOS in European sea bass (Torrecillas et al, 2007), respectively.…”

“…The facts suggest that increased alternative complement activity and increased levels of total immunoglobulin and lysozyme activity of sobaity seabream fed with 5g/kg XOS may be attributed to the supplemented prebiotic, confirming the benefit for the nonspecific innate immunity of this fish. Some data regarding immunological parameters have previously been reported positive, negative and unaffected effects in fish fed with FOS in Caspian roach ( Rutilus rutilus ) and inulin in Nile tilapia (Soleimani, Hoseinifar, Merrifield, Barati, & Abadi, ; Tiengtam et al., ), inulin in gilthead seabream (Cerezuela, Cuesta, Meseguer, & Esteban, ) and MOS in European sea bass (Torrecillas et al., ), respectively.…”

“…It has also been suggested that experimental conditions, feeding duration, intestinal microbiota and species-specific might have contributions to exist contradictory results (Dimitroglou et al, 2010;Hoseinifar et al, 2014). (Torrecillas et al, 2007(Torrecillas et al, , 2015 and Nile tilapia (Oreochromis niloticus) (Tiengtam, Paengkoum, Sirivoharn, Phonsiri, & Boonanuntanasarn, 2017). In contrast to this result, the elevated carcass protein was reported in Atlantic salmon It is demonstrated that administration of prebiotics can influence both humoral and cellular components of the innate immune system in fish by improving growth and/or activity of beneficial bacteria such as Lactobacillus and Bifidobacterium in the intestine (Ringø et al, 2010).…”

Dietary supplementation of Viligen™ to Nile tilapia improves growth and gut morphology

“…The tilapia group is the second most produced fish worldwide, after the carps (FAO, 2018), and its production is expected to further increase to reach the global food demand (Tiengtam et al, 2017). Nile tilapia, Oreochormis niloticus , is the target species of this study; it presents highly favourable characteristics for aquaculture, such as fast growth in high densities, hardiness, easy reproduction and high market acceptance (Watanabe et al, 2002).…”
