“…Dietary phytase improved the digestibility of crude protein, crude lipid, DM, ash, P and Ca when phytase addition level was above 1,000 U/kg (Liu et al., ). The similar results were also reported in yellow catfish (Zhu, Ding, Chan, Chen, & Wang, ) and L. rohita (Hussain et al., ). Cheng et al.…”

A 10‐week study was conducted to evaluate the effects of supplemental phytase and protease in low phosphorus (LP) and fishmeal‐free diets (FMF) on growth and nutrient utilization of tilapia. Seven isonitrogenous diets were prepared as positive control diet (PC) containing 60 g/kg fishmeal and 18 g/kg monocalcium phosphate (MCP), LP diet (12 g/kg MCP), FMF diet, LP‐FMF diet, and three enzyme diets with phytase (LP + Ph), protease (FMF + Pr), and phytase + protease (LP‐FMF + Ph + Pr) supplementation in LP, FMF and LP‐FMF diets, respectively. Weight gain, nutrient (except Ca) retention and digestibility of LP, FMF and LP‐FMF groups were lower than those of PC group (p < 0.05). Compared to LP, FMF and LP‐FMF groups, the supplementation of phytase, protease and phytase + protease improved WG by 13.2%, 11.1% and 13.0% (p < 0.05). The three enzyme groups showed higher digestibility of protein and P, and higher intestinal villus length than those of LP, FMF and LP‐FMF groups (p < 0.05), respectively. Dietary phytase and Ph + Pr also promoted the retentions of crude protein and P (p < 0.05). The results indicated that the supplementation of phytase in LP diet and protease in FMF diet improved the growth and nutrient utilization, and phytase reduced MCP inclusion in the diet of tilapia.

“…Mineral contents were analysed using an inductively coupled plasma optical emission spectrometer (ICP‐OES) (PerkinElmer 8000, Waltham, MA, USA). The sample preparation procedure for ICP‐OES was according to Zhu, Ding, Chan, Chen and Wang (). pH, dissolved oxygen, NH 4 + ‐N and NO 3 − ‐N was measured using YSI Professional Plus (Pro Plus) probe (YSI, Yellow Springs, OH, USA).…”

An 8‐week feeding trial was conducted to evaluate the sparing effect of dietary phytase on decreasing supplement of dietary sodium dihydrogen phosphate (NaH2PO4) in the diets of juvenile yellow catfish Pelteobagrus fulvidraco. Seven diets were formulated: one reference group that contained only 2% NaH2PO4; one control group that consisted of neither NaH2PO4 nor phytase; and five treatment groups supplemented with 1000 IU kg−1 phytase and 2%, 1.5%, 1%, 0.5%, 0% concentrations of NaH2PO4. Thus, dietary NaH2PO4 was substituted with phytase at ratios of 0%, 25%, 50%, 75% and 100% respectively. Triplicate tanks were each filled with 50 juvenile fish (3.5 ± 0.1 g), which were fed one of the seven experimental diets. Substituting phytase for NaH2PO4 didn't diminish the growth performance, protein, dry matter, lipid and ash deposit and protein retention in the whole body and reduced feed conversion ratio compared to the reference diet. Moreover, phytase substitution at level of 0–50% enhanced P, Mg and Ca deposit. However, weigh gain had a tendendy of decreasing with increasing substituted level. Phytase substituted level exceeding 75% decreased serum P concentration compared to the control group. Apparent digestibility of P peaked when 1000 IU kg−1 phytase substituted 50% NaH2PO4. Phytase also increased apparent digestibility of protein. The improvement of digestibility of protein and P resulted in the decrease in N load by 25% and P load by 31% to environment. Therefore, 50% dietary NaH2PO4 can be substituted by 1000 IU kg−1 feed phytase for juvenile yellow catfish.

“…In the combination of organic acid (or organic acid salts) and enzymes, most of the reports focused on phytase (Baruah et al, 2007;Emami, Naeini, & Ruiz-Feria, 2013;Zhu et al, 2015) and…”

“…The combined inclusion of organic acids and enzyme mainly focused on organic acids and phytase, including citric acid (Baruah et al, 2005(Baruah et al, , 2007Zhu, Ding, Chan, Chen, & Wang, 2015), acetic acid (Valencia & Chavez, 2002) and benzoic acid (Bühler, Bucher, & Wenk, 2010). But relatively fewer studies were conducted in organic acid and protease, only Ao, Cantor, Pescatore, Pierce, and Dawson (2010) reported that citric acid improved the ability of acidic protease to hydrolyse soybean meal.…”

A study was conducted to evaluate the effects of organic acid salt blend (OAB), protease complex (Pr) and their combination (OAB+Pr) in fish meal‐free diets on growth, nutrient retention and digestibility of tilapia. Five diets were designed: a positive control (PC) diet containing 80 g/kg fish meal (FM), a negative control (NC) diet containing 0 g/kg FM and 104 g/kg meat and bone meal, and three other diets supplemented with OAB (922 mg/kg), Pr (175 mg/kg) and OAB+Pr (922 mg/kg + 175 mg/kg) to the NC diet. Tilapia with an initial body weight of 7.0 ± 0.2 g were fed the five diets for 9 weeks. The results showed that the growth performance, nutrient digestibility and retention of NC group had the lowest values among groups. Weight gain of fish fed the OAB and OAB+Pr diets was higher, and feed conversion ratio was lower (p < 0.05) compared to those fed the NC diet, while no differences with those fed the PC diet. The digestibility of dry matter, crude protein, minerals and protein retention was improved in fish fed the OAB+Pr diet (p < 0.05), but not in those fed OAB or Pr diet (p > 0.05). There were no differences in whole‐body composition and lipid retention among the treatments (p > 0.05). The supplementation of OAB and Pr alone or combined significantly increased the villi height but not the width when compared to the NC group. It can be concluded that dietary supplementation of OAB+Pr in a fish meal‐free diet improves growth and nutrient digestibility in tilapia compared to those fed the fish meal‐free diet.
