“…The group of fish fed on D4 had highest a significant difference (p<0.05) in growth performance and feed utilization in comparison to the control and phytase diets. This is in agreement with other studies on different species including tilapia (Maas et al, 2018 andAbo Norag et al, 2018), L. rohita (Shah et al, 2016 andBano and and Cirrhinus mrigala (Hussain et al, 2017). The increased growth response may be due to increased availability of nutrients and minerals by enzymatic breakdown of phytatenutrient complexes (Shah et al, 2016).…”

This experiment was aimed to investigate the effect of phytase, citric acid and their interaction on growth performance, feed utilization, body composition, economic evaluation and its antibacterial activity against fish pathogens of Nile tilapia fingerlings. Nine isonitrogenous 30 % CP and isocaloric 450.27 Kcal/100g experimental diets were prepared. Phytase was added at the level 0, 1000 and 2000 FTU/kg diet while citric acid was added at the level of 0, 30 and 60 g in the experimental diets. Six hundred and seventy five of Nile tilapia fingerlings were placed randomly in twenty seven V-shaped fiber tanks 120 L capacity of water /tank, in three replicates per treatment was used in this study. Each tank stocked with twenty five fingerlings of with an average initial body weight of 12.47±0.3g /fish. Fish were acclimated to laboratory conditions for 2 weeks prior before the experimental started. Photoperiod was 12h light/ 12h dark regulate. Fish were hand-fed to satiation, two times daily for six days a week through the whole experimental period (60 days). The results indicated that the best growth performance and feed utilization of Nile tilapia fingerlings fed on D5 (1000 FTU phytase / kg + 30g citric acid/ kg) and the lowest group fed on control diet (D1). While, antibacterial activity showed that citric acid alone and citric acid with phytase had highest activity and gave wide inhibition zones against all tested and isolated bacteria which infect Nile tilapia compare with different used antibiotics. Phytase and citric acid positively affected the growth performance, feed utilization,

“…The test ingredients (WB, SFM & CP) affected the ADC of all nutrient (p < 0.001), except for the starch and Ca ( (Amirkolaie, Verreth, & Schrama, 2006;Haidar et al, 2016;Leenhouwers, Veld et al, 2007;Maas, Verdegem, Dersjant-Li, & Schrama, 2018;Schneider et al, 2004;Schrama et al, 2012) performed at the same facilities (ARF; Wageningen University & Research). The FCR for the NSP-rich control (no enzymes) were 1.00, 1.12 and 1.04 for the WB, SFM and CP diets, respectively.…”

The experiment investigated whether the effect of enzyme supplementation on performance and nutrient digestibility is dependent on type of the ingredient(s) used, by incorporating wheat bran (WB), sunflower meal (SFM) and citrus pulp (CP) to a reference diet (REF). Those ingredients are known to be rich in different types of non‐starch polysaccharides (NSP). Diets were supplemented with and without (control) an enzyme mix (phytase 1,000 FTU/kg and xylanase U/kg) according to a 2 × 4 factorial arrangement. In total, 24 tanks (3 replicates/treatment) were used with 30 fish each (Nile tilapia, Oreochromis niloticus; mean initial body weight 41 g). Fish were restrictively fed the experimental diets for 43 days (80% of expected satiation). Enzyme supplementation affected the absolute growth (g/day) and FCR (p < 0.05), improving the growth of fish fed the WB and SFM diets, while fish fed the REF and CP diets did not benefit. NSP, energy, ash, phosphorous and calcium digestibility improved with enzyme supplementation (p < 0.05). There was an interaction effect on all growth parameters, as well as the digestibility of energy and phosphorus (p < 0.05). This indicates that the effectiveness of the enzymes was dependent on the NSP‐rich ingredient used and thus the composition of the NSP fraction.

“…However, the impact did not spread to growth performance. The increase in nutrient digestibility by xylanase did not result in improved growth parameters that were also observed in Nile tilapia, Oreochromis niloticus (Maas, Verdegem, Dersjant‐Li, & Schrama, ). With regard to Chinese mitten crab, it may also be due to its special growth pattern.…”

“…Studies assessing the effect of xylanase on growth and nutrient digestibility in aquatic animals are minimal compared to pigs and poultry (Castillo & Gatlin, ). It was reported that xylanase improved the nutrient availability and growth in Nile tilapia, Oreochromis niloticus (Maas et al, ), rainbow trout, Oncorhynchus mykiss n. (Dalsgaard et al, ) and juvenile Jian carp, Cyprinus carpio var. Jian (Jiang et al, ).…”

Effects of xylan and cottonseed meal on growth performance, digestion, intestinal morphology and the expression of two peritrophin genes of Chinese mitten crab,Eriocheir sinensis

Xylan is one of the main non‐starch polysaccharides (NSPs) in cottonseed meal. This study aimed to evaluate the anti‐nutrition effect of xylan and to better understand cottonseed meal as a feed ingredient for the Chinese mitten crab, Eriocheir sinensis. A diet containing 280 g/kg fishmeal without cottonseed meal or xylan was formulated as a control (FM diet). A second diet (XYL diet) was supplemented with 53.3 g/kg xylan according to its amount in the third diet, the cottonseed meal diet (CSM diet), which was formulated to include 400 g/kg cottonseed meal. The last diet (CSM + XYLase diet) included 400 g/kg xylanase hydrolysed cottonseed meal, in which most xylan was hydrolysed. Diets were isonitrogenous (370 g/kg crude protein) and isoenergetic (17.58 KJ/g) and were randomly fed to 12 tanks of crabs for 8 weeks. Results showed that no difference was detected among groups in growth performance, serum biochemical index, or digestive and metabolism enzyme activity (p > 0.05). The apparent digestibility coefficient (ADC) of dry matter was FM > XYL > CSM + XYLase > CSM (p < 0.05). The ADC of protein in crab fed diet FM and XYL was significantly higher than CSM and CSM + XYLase (p < 0.05). Cottonseed meal decreased the fold height of the hindgut, upregulated the expression of peritrophin genes of Es‐PL44 and Es‐PP1 (p < 0.05), while xylan decreased the fold height of the hindgut and upregulated the expression of Es‐PP1 (p < 0.05). These results indicated that the negative effect of cottonseed meal and xylan on digestibility partly compensated by enhanced absorption of the hindgut innerly and by supplementation of xylanase externally, and cottonseed meal is an attractive alternative protein source in general for Chinese mitten crab.
