“…Lack of positive response to supplemental phytase on the shell thickness, shell ash content and the latency to lie may be due to the use of an adequate level of dietary Non Phytate Phosphorus (NPP) level. As in the present experiment, supplementation of a quail diet having 0.3% (Vali and Jalali, 2010) and 0.35% (Sacakli et al, 2006) of NPP with phytase has not improved growth performance, carcass yield, percentage of tibia ash or tibia phosphorus of Japanese quail.…”

Cost of quail feed formulations can be reduced substantially by using cheap cereal by-products such as rice bran (RB) at higher levels. The objective of this study was to determine the maximum inclusion levels of dietary RB with or without exogenous phytase, for laying Japanese quail. In a completely randomized design with a 3 x 2 factorial arrangement, 108 quails in 36 cages received six experimental diets ad libitum from 8 to 15 week. Experimental factors were three dietary RB inclusion levels (20, 30 and 40%) and two phytase levels (0 and 1000 FTU/kg). The level of dietary RB, phytase supplementation and their interaction had no significant effects on live weight or feed intake. The total egg production of the quail fed 40% RB was significantly lower than that of quail fed 20 and 30% RB. Egg laying rate of the quail fed 40% RB was significantly lower than those of the quail fed 20 or 30% RB from 6 th week onwards. By eighth week, 30% RB resulted in significantly lower egg laying rate compared to the quail fed 20% RB. Feed conversion ratio (FCR) of the quail fed 40% RB was significantly higher than those of 20 or 30 % RB fed. Adverse effects of phytate in 30 or 40% RB on egg number, egg mass and FCR were not mitigated by the supplemental phytase. It is concluded that inclusion of more than 20% RB in the diets of laying Japanese quail reduces the production performances.

Abstract-An experiment was conducted to study the effects of phytase enzyme on performance, blood biochemical parameter and tibia ash content of broiler chicks. Two hundred eighty Ross broiler chicks were located randomly to seven experimental diets at four replicates (cages) and fed from 5 to 28 days of age. A positive control diet (0.422% non-Phytate Phosphorus, nPP) and a negative control diet (0.316% nPP) were used, and five more diets were manufactured by supplementing the negative control diet with 300, 600, 1,200, 2,400, and 24,000 FTU/kg of exogenous phytase (Phyzyme XP). The addition of exogenous phytase above 600 FTU/kg and 1200 FTU/kg improved (P<0.05) feed conversion ratio and body weight gain of the birds fed the negative control diet, respectively. Decreasing nPP content in the diet reduced tibia ash (P<0.001) content and phytase supplementation increased it (P<0.001) as logarithmic liner equation. Phosphorus concentration of serum chicks fed negative control diet was reduced and phytase supplementation above 600 FTU/kg increased it. However, negative control diet increased alkaline phosphatase activity of serum and addition of phytase above 2400 FTU/kg reduced its activity to level of positive control diet (P<0.01). Albumin concentration of serum chicks was increased by addition of phytase above 600 FTU/kg diet. The lowest calcium content and highest total protein concentration of serum chicks were seen at treatment of 600 FTU/kg phytase. These results demonstrated that addition of 600 FTU/kg phytase to low-available phosphorus diets (75% of NRC recommended) improved performance of broiler chicks due to improve utilization of phytate phosphorus of corn-soy bean meal diets.
