Phytic acid and phytate, and the anti-nutritional function

1£®  he chemical name of phytic acid is myo-inositol 1, 2, 3, 4, 5, 6 hexakis dihydrogen phosphate, it always binds with mineral element and generates phytate, which exists widely     in plant. Especially in the seed of paddy, corn, bean, and oil plants, the content of phytate reaches 1%~5%. And 50%~80% of the total phosphorus exists in the form of phytate in seed. Phytate is the basic reserve form of phosphorus in plant.

Table      Phytate content in common-used botanic materia

From: China Feed Raw Material Data Base, 14th edition, 2003.

2£®  phytate cannot be utilized by animal until it is hydrolyzed into inorganic phosphate in digest tract, but the monogastric animal can hardly secrete the phytase. Therefore, animal cannot utilize the phosphorus in botanic feed material sufficiently.

3£®Phytic acid is one kind of the anti-nutritional factor. It carries negative charge in the narrow Ph value, and can chelate with protein or cation with positive charge  , which is a strong chelator.

n         Phytic acid can bind with the metal ions such as Ca, Mg, Cu, Fe, Mn, and Zn, and form stable compound Thus it makes the ion hard to be digested and utilized, and burdens the need of such ion.

n         In the low or medium Ph value, phytic acid will bind with the alkaline group of protein and precipitate the protein, which lowers the digestion and utilization of protein.

n         Phytic acid also can inhibit or reduce the activity of proteinase, amylase, and lipase in digestive tract, thus influences the regular metabolism and physiological function.

It is proved that, applying phytase, which yield from the modern bio-engineering technique, is one of the most efficient ways to enhance the utilization of phosphorus in vegetable feed material and reduce the anti-nutritional function of phytic acid.

Function Principle of Microtech 5000

î        Hydrolyze phosphoinositide ester bond, release phosphorus, and enhance the utilization rate of phosphorus in feed material.

î        Destroy the chelated structure of phytate, release the nutrients such as mineral element, protein, and starch, and enhance the utilization of them.

Factors to affect function of Phytase

n         Applied effect of phytate relates to the phytate content in feed material. If the phytate content is low in feed material, then it cannot offer sufficient substrate for phytase to release enough phosphorus in need for animal, though phytase is plenteous.

n         The granular processes must pass through the high-heat regulate granulating, and it can destroy the activity of the regular powder phytase. VTR's Granular Microtech 5000  has adopted the advanced granulating technique, which largely increase the heat-endurance, and makes it more suitable for granular feed.

Under the model heat and humidity condition of feed steam-regulate pelletizing, treat the  Microtech 5000 granular and the powder phytase product for 10 min with different temperature. The compared result of the remain relative activity of the phytase:

Microtech 5000 can solve the following problems:

n         Reduce the dosage of inorganic phosphorous  such as Dicalcium Phosphate, lower the formula cost.

n         Increase the utilization of mineral element, reduce the metabolic disease led by the shortage of mineral element.

n         Increase the utilization of nutrient such as protein and starch, improve animal's performance.

n         Enlarge the feed formula space, improve formula.

n         Replace most dicalcium phosphate and bone powder, reduce the heavy metal toxicosis in feed, and microorganism pollution.

n         Reduce the dust pollution in feed processing, reduce the waste of inorganic phosphorus source.

n         Reduce the total phosphorus level in feed, reduce the secretion of phosphorus in feces, protect environment.

n         Good resistance, Granular Microtech5000 has  strong heat-endurance, more suitable for using in granular feed.

Replace 80%, 100%, 100% phytate with 60g/T, 80g/T and 110g/T Microtech 5000 respectively as available phosphorus, to cover the corresponding dicalcium phosphate in layer diet. The influence to layer's Ca and crude ash in bone is not notable £¨p>0.05£©. While the utilization of P in group 60g/T of Microtech 500 is much higher than that of the control group £¨p<0.05£©.

Replace 80%, 100%, 100% phytate with 60g/T, 80g/T and 110g/T Microtech 5000 respectively as available phosphorus, to cover the corresponding dicalcium phosphate in layer diet. The influence to layer's production and average egg weight is not notable £¨p>0.05£©. It indicates that replace dicalcium phosphate with Microtech 5000 will not influence layer's performance.

Usage

n         Manual calculation

Method 1:  Add Microtech 5000 base on the above dosage can replace 50%~75% Dicalcium phosphate in feed, meanwhile add limestone to supplement the Ca content in Dicalcium phosphate. The rest formula space can be applied to modify the formula or supplement with the inexpensive material such as zeolite.

Method 2: Calculate the phytate content in feed, and add Microtech 5000 according to the proportion of 1gram phytate: 150~200U phytase. Then calculate the available P which it can provide, and confirm the replacement of  dicalcium phosphate. Meanwhile, add limestone to supplement the Ca content in dicalcium phosphate. The rest formula space                  can be  applied to modify the formula or supplement with the inexpensive material such as zeolite.
