“…These enzymes are also widely used to reduce the anti-nutritional effects of non-starch polysaccharide (NSP) in the feed of monogastric animals including pigs and poultry (Alloui et al, 1994;Ghazi et al, 2003;Esonu et al, 2005). The application of phytase has been successful in breaking down phytate to increase mineral and nutrient digestibility that in turn improves the growth performance of fish (Cao et al, 2007;Cao et al, 2008;Kiarie et al, 2013;Adeoye et al, 2016). NSPdegrading enzymes (e.g.…”

A 60-day feeding trial was conducted to study the nutrient utilization and growth performance of Labeo rohita fed with T1 [DORB supplemented with phytase and xylanase (0.01% each)], T2 [ T1+ L-lysine(1.4%), L-methionine (0.4%), combination of EPA and DHA (0.5%)] , T3 [DORB supplemented with phytase (0.01%), combination of xylanase and cellulase (0.075%), L-lysine (1.4 %), L-methionine (0.4 %), combination of EPA and DHA (0.5%)] and T4 (commercially available carp feed) diets. Weight gain%, SGR, and FCR were similar (p>0.05) for the fishes fed with either T3 feed or commercial carp feed (T4), whereas PER was highest for the T3 group. A significantly higher apparent dry matter and carbohydrate digestibility were observed in the T3 group. Highest crude protein digestibility was observed in T4 group, though lipid digestibility was similar in both T3 and T4 groups. The activities of digestive enzymes were similar in T2, T3 and T4 groups, whereas the lowest activity of these enzymes were observed in T1 group. Based on the findings it is concluded that T3 feed (crude protein 18.18 %) is having comparable growth performance of Labeo rohita as compared to T4 diet (crude protein 32.01 %) due to higher In vivo digestibility.

“…This negative effect could be attributed to the elevated content of readily available P of the diet which may decrease the efficacy of P retention in fish [46]. In addition, the positive correlation between dietary P and P waste of fish has been reported in previous studies [24,[47][48][49][50][51].…”

“…The enhancement of P utilization and reduction of total P waste of fish fed with phytase supplemented plant-based diets have been reported in previous studies [17,5,[41][42][43][44]. The common explanations for the improvement of dietary P utilization were: (1) the liberation of chelated phytate-P by phytase leading to higher availability of dietary P [45]; and (2) the promotion of P deposition in fish by dietary phytase leading to higher P utilization and low P waste discharged by fish [46]. In the current study, phytase only showed a significant effect on total P waste of fish when CM replaced 45% dietary FM protein and only when used in combination with supplemented AAs.…”

Effects of dietary phytase, amino acid (AA), and inorganic phosphorus (P) in canola meal diets on the growth and P waste production of Australian catfish, Tandanus tandanus were evaluated. Fishmeal protein was replaced by 30% and 45% with canola meal protein in two separate experiments, in which test diets were fortified with phytase, AA, inorganic P, or their combinations. Addition of sole phytase to the 30% replacement diets did improve growth performance and feed utilization of fish compared to those fed with the non-phytase diet. Inclusion of phytase and/ or AAs did not improve the growth and feed utilization of catfish when fishmeal protein was replaced by 45% while adding inorganic P showed significant improvement in the performance of the fish. Ortho-P waste was significantly lower while total P waste was significantly higher in fish fed with canola meal diets at both levels of fishmeal replacement. Phytase did not affect the total P waste of catfish but a combination of phytase and AA resulted in a significant reduction. Dietary inclusion of inorganic P significantly elevated the total P waste of catfish compared to that of the control fish. It was concluded that the use of canola meal in combination with inorganic P in diets for Australian catfish could significantly increase nutrient pollution in aquaculture

The research investigated the interactive effect of five phytase graded levels of 0 FTU/g (P0), 250 FTU/g (P1), 500 FTU/g (P2), 750 FTU/g (P3), 1000 FTU/g (P4) and four graded levels of roasted soya bean substitution at 25%, 50%, 75% and 100% in place of fish meal, respectively. All basal diets contained 0.20% calcium without added inorganic phosphorus, wheat and amino acids supplements so that the phosphorus, calcium, and Ca/P ratios of the five (5) were: S0 (1.31%, 1.85%, and 1.41), S1 (1.15%, 1.64%, and 1.43), S2 (1.01%, 1.28%, and 1.27), S3 (0.75%, 0.99%, and 1.30), and S4 (0.43%, 0.68%, and 1.59). 1092 fish of average weight 11.55 ± 0.2 g were randomly allocated to all experimental diet and fed 3% body for 84 days. There was no significant difference in final weight, weight gain and FCR S3P1 and S0P0 (P>0.05). Fish fed low phosphorus diet (100% soya bean) showed reduced total weight and weight gain compared to high (0%, 25%, 50%) and medium phosphorus diet (75%) with phytase addition (P<0.05). Fish fed phytase at 50-200 FTU/g and inorganic control had lower weight gain compared to S3P1 (P<0.05). Ca/P ratio correlated negatively with final weight (r=-0.439, P<0.01), weight gain (r=-0.431, P<0.01), SGR (r=-0.138, P>0.05), and PER (r=-0.210, P>0.05). Ca/P of S3P1 (1.41 ± 0.02) was not different from S0P0 (1.41 ± 0.01). Bone phosphorus, calcium and zinc were higher in 250 FTU/g compared to 0 FTU/g, 500 FTU/g, 750 FTU/g and 1000 FTU/g. In conclusion, Phytase improved growth performance (r=0.05) of juvenile Clarias gariepinus with optimum at 250 FTU/g; however, Ca/P affected performance (r=-0.431) and should range between 1.41-1.46 for optimum phytase activity.
