“…Variations in optimal level of phytase supplementation may be due to difference in plant ingredients used in diet formulation and experimental fish species (Dersjant-Li et al, 2015). In contrary to these findings and present results, Laining et al (2011) observed highest mineral digestibility and absorption in Takifu gurubripes (tiger puffer), when fed with phytase supplementation at 2000 FTU kg -1 in soybean meal based diet. In another study Nwanna and Bello (2014) suggested that phytase supplementation played a non-significant role in term of mineral digestibility in Oreochromis niloticus, Nile tilapia fingerlings.…”

A 90-days feeding trial was conducted to determine the influence of phytase on growth and mineral availability to Catla catla fingerlings fed mixture of Moringa oleifera leaf meal (MOLM) and M. oleifera seed meal (MOSM) based diets. Due to the presence of anti-nutritional factors in plant by-products based diets, reduced mineral availability to fish results in poor fish growth performance. Phytase enzyme is beneficial to decrease these anti-nutritional effects of plant based diets. MOLM+MOSM mixture was used to prepare six test diets that were supplemented with graded levels (0, 300, 600, 900, 1200 and 1500 FTU kg -1 ) of phytase. Fingerlings were fed at the rate of 4% live wet weight twice a day. On the basis of results it was noted that addition of phytase showed significant (P<0.05) enhancement in bioavailability of minerals, resulting in improved growth performance (weight gain 229%, SGR 1.32 and FCR 1.3). Maximum (ADC%) of minerals was noted at 900 FTU kg -1 level of phytase supplemented MOLM+MOSM based diet. On the basis of these results it was suggested that phytase supplementation at 900 FTU kg -1 level is helpful to develop an eco-friendly and cost effective fish feed by using moringa by-products based diet.

“…In addition, growth of Japanese flounder significantly enhanced by supplementing either dietary IP or phyatse even when Ca did not present in the diet and highest SGR was found when these three nutrients were included together (Laining et al, 2013). This finding indicated that Japanese flounder seemed to have the capacity to uptake Ca from seawater to meet the requirement level for growth which supported the previous results found in tiger puffer (Laining et al, 2011). Flik et al (1995 reported that Ca is actively absorbed through the gill epithelium in freshwater fish whereas in marine fish Ca is transported across the intestinal epithelium.…”

“…Supplementation of dietary Ca at level of 0.2% did not induce the inhibitory effect on P and Mg accumulation in vertebrae indicating that this level was not over-dosage that may interfere with other mineral availability. Intestinal interactions between Mg and Ca or P are well documented in terrestrial vertebrates as well as fish as found in tiger puffer (Laining et al, 2011). Dietary requirement of Mg have been reported on several species such as tilapia (Flik et al, 1993), carp (van der Velden et al, 1992 and rainbow trout (Shearer & Asgard, 1992).…”

“…Moreover, enhancement of phosphorus utilization originated from phytic acid through supplementing phytase in diet have also been widely reported ( (Applegate et al, 2003;Tamim et al, 2004;Kemme et al, 2006;Liebert & Portz, 2007 though, many studies on mineral requirement have been reported on aquatic species, still few studies reported the interrelation between mineral in fish. Relationship between mineral can be synergetic and antagonistic interrelationships (Lall, 2002;Apines et al, 2003;Laining et al, 2011).…”

Interactive effects between dietary inorganic phosphorus (IP) and phytase (P) on mineral digestibility and vertebral mineral content were investigated in a 30 days feeding trial followed by three weeks digestibility trial with Japanese flounder, Paralichthys olivaceus. Eight experimental diets were formulated based on two levels of dietary Ca at 0% and 0.2% combined with either 0% or 0.25% of dietary IP and either with 0 and 2,000 fytase unit (FTU)/kg of phytase in diet, respectively. Result indicated that digestibility of total phosphorus significantly increased by three dietary compounds where the highest was observed in fish fed diet contained 0.25% IP and 2,000 FTU phytase/kg and dietary Ca also included in diet. Significant interaction was only detected between dietary IP and P on this parameter. Supplementation of IP and Ca not phytase significantly improved Ca digestibility. Ca digestibility was very poor when dietary IP and Ca were not supplemented in diet even with when phytase supplemented in diet. There was significant interaction between dietary IP and Ca on Ca digestibility. Vertebral total phosphorus, Ca, and Mg content as well as Ca:P ratio were significantly enhanced by dietary IP and phytase. Dietary Ca has significant effect only on vertebral total phosphorus. Interaction between dietary IP and Ca was significantly found on vertebral Ca content and Ca:P ratio. No significant second-order interaction was observed among the three dietary mineral on overall parameters. Based on total phosphorus and Ca digestibility as well vertebral phosphorus content found in this study, dietary IP, Ca, and phytase at rate of 0.25%, 0.2%, and 2,000 FTU phytase/kg diet, respectively are needed to supplement in diet for a better mineral absorption and bone mineralization.

“…However, limit information is available in fish species including our previous study dealing with juvenile tiger puffer (Laining et al, 2010b). In regard to growth performances, dietary Ca/ P ratio of 0.5 or without additional Ca supplement combined with 2000 FTU phytase per kg might be the optimum combination in diet for tiger puffer.…”

In order to investigate the phytic acid degradation in the gut of post juvenile Japanese flounder, indirect method was carried out by measuring the pre-prandial and postprandial plasma mineral and alkaline phosphatase (ALP) level as well as liver phosphorus content. The experiment was designed into a Randomized Block in which experiment units were grouped according to sampling days at 10, 20 and 30 days of feeding time. Experimental diets contained three levels of dietary inorganic phosphorus at 0.0; 0.25 and 0.5% combined with two levels of dietary phytase at 0 and 2000 FTU/kg diet. Juvenile Japanese flounder (IBW = 36.2 g) were randomly distributed into 6 tanks of a 200 L capacity with density of 15 fish/tank. Blood sampling was carried out at 0 hour (before feeding or pre-prandial) and at 1, 3, 6 and 12 hour post feeding (post-prandial) time in three sampling days, respectively. Plasma was measured for mineral and ALP levels, while liver was analyzed for P content. The observation showed that fish fed without both dietary IP and phytase supplements had the lowest postprandial plasma IP, Mg and ALP levels during 12-h postprandial period. Plasma IP level at 6-h post-feeding in groups fed dietary 0.25 and 0.5% IP were significant higher when diet supplemented with phytase than those without phytase supplement. Peak level of plasma IP in fish fed 0.25% IP was similar to fish fed 0.5% with the presence of dietary phytase. At 1 and 3-h post-feeding, plasma Ca level increased in all groups, but significant difference was only observed between group fed diet without both dietary IP and phytase and other groups. Similar to plasma IP level, peak of plasma Mg and ALP concentration occurred in fish fed 0.25% IP together with phytase, and did not significantly differ from fish fed with 0.5% IP even when phytase was included in diet.
