A total of 420 day-old male Ross chicks were weighed at d 1 of life and assigned to test diets to assess the efficacy of a new Buttiauxella spp. phytase expressed in Trichoderma reesei. Diets were: po...
The objective of this study was to investigate the effect of Ca : total(t) P ratio, vitamin C and microbial phytase on broiler performance and cadmium retention of broiler. In experiment, 288 day-old ...
The use of a suitable methodology to quantify the phytate phosphorus (Pphy) content in both the feed and the excreta from broilers is required to enable accurate calculation of the catalytic efficienc...
The study aimed to evaluate the potential effects of feeding with phytase transgenic corn (PTC) on organ weight, serum biochemical parameters and nutrient digestibility, and to determine the fate of t...
Phytate is not only an unavailable source of phosphorus (P) for broilers but it also acts as an anti-nutrient, reducing protein and mineral absorption, increasing endogenous losses and reducing broile...
A bacterial isolate derived from soil samples near a cattle farm was found to display extracellular phytase activity. Based on 16S rRNA sequence analysis, the strain was named Bacillus sp. T4. The opt...
Two experiments were conducted to evaluate the efficacy of Trichoderma reesei derived phytase for pigs fed diets with fixed calcium to total phosphorus ratios (1.5:1). In Exp. 1, 280 weaned pigs (init...
Two experiments were conducted to evaluate the effects of addition of sodium polyacrylate (SPA) to a phytase-supplemented diet on the performance and phosphorus (P) retention of chicks. In experiment ...
This study was conducted to investigate the effects of dietary supplementation with multiple enzymes composed of phytase plus carbohydrolases (ROVABIO Max, RM) on growth performance, nutrition...
In order to improve the availability of phytase and probiotics together, a phytase gene from Aspergillus ficuum has been expressed in Lactobacillus. In this study, the transformed Lactobacillus with p...
The reported effects of dietary supplemented microbial phytase on the utilization of phytate phosphorus (pP) differ widely by investigators. In order to clarify the differences, the contents of total ...
An experiment was conducted to study the effect of microbial phytase on excretory phosphorus (P), copper (Cu), zinc (Zn) and manganese (Mn) in broiler chicks. Male broiler chicks with three replicatio...
The optimum pH of phytase originated from Aspergillus niger is approximately 5.5. In the present study, we tried to modify the intraluminal pH by dietary acidic amino acid to maximize phytase activity...
In the purpose to reducing excretion of nitrogen (N) and phosphorus (P) without the influence of the growth performances and abdominal fat in broilers, a feeding trial and balance test were conducted....
A total of 192 d-old Arbor Acres broiler chicks were fed ad libitum up to 42 d of 16 isonitrogeneous and isocaloric diets of different combination levels of phytase (0, 750, 1000 and 1250FYT/kg) (FYT=...
