There is little consensus as to the capability of poultry to utilize dietary phytate without supplemental phytase. Therefore, an experiment was conducted to examine the extent to which endogenous phytase of intestinal and cereal origin contributes to phytate degradation in birds aged 0 to 14 d posthatch. Ross 308 broilers (n = 720) were fed one of 4 experimental diets with differing dietary ing...

The effect of local Indonesian microbial phytase, derived from L. plantarum A1-E extracted the small intestine free-range chickens and C. tropicalis TKd-3 obtained fermented soybean tempe, on growth performance, metabolizable energy, ileal histomorphology, meat bone mineralization in broilers is subject evaluation this study. A total 140 day-old broiler chicks were divided into four treatments,...

In this study, an extracellular alkali-thermostable phytase producing bacteria, Bacillus subtilis B.S.46, were isolated and molecularly identified using 16S rRNA sequencing. Response surface methodology was applied to study the interaction effects of assay conditions to obtain optimum value for maximizing phytase activity. The optimization resulted in 137% (4.627 U/mL) increase in phytase activ...

Pigs digest P in plant feedstuffs poorly because pigs do not produce sufficient endogenous phytase to hydrolyze P from phytate (inositol hexaphosphate). Supplementation of phytase to diets of piglets and grower-finisher pigs increased digestibility of minerals including P and Ca; however, data on phytase efficacy in lactating sows are scarce. Therefore, effects of adding a bacterial 6-phytase e...

Aspergillus fumigatus contains a heat-stable phytase of great potential. To determine whether this phytase could be expressed in plants as a functional enzyme, we introduced the phytase gene from A. fumigatus (fphyA) in tobacco (Nicotiana tabacum L. cv. NC89) by Agrobacterium-mediated transformation. Phytase expression was controlled by the cauliflower mosaic virus (CaMV) 35S promoter. Secretio...

Phytate phosphorus of plant ingredients is not substantially available to poultry because of the lack of endogenous phytase enzymes in their gastrointestinal tract. There are substantial differences among broilers, turkeys, and ducks in terms of plant P utilization. We studied whether the availability of P is different for two Phytase enzymes in turkeys. Finase and a New Phytase product develop...

Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...

The objective of the study was to determine the effect of Quantum Blue phytase on P utilisation and bone parameter in laying hens fed barley, oat and soybean meal based diets. Over a period of 40 days 64 laying hens (from 29 weeks of age) were distributed to 4 treatments (8 cages, two birds each). Experimental diets with no inorganic P added were supplemented with 0, 150, 300 or 1200 FTU phytas...

Optimization for enhanced phytase production by Aspergillus oryzae SBS50 in submerged fermentation was investigated using Taguchi design. In first step design, starch, beef extract, magnesium sulphate, ferrous sulphate and Tween 80 were identified as significant factors affecting phytase production. These significant factors were further optimized at four different levels using a second Taguchi...
