Diet Manipulation to Reduce Phosphorus Excretion by Poultry

the use of phytase as feed additive is widespreed in current animal feeding industry ,thus with such manipulation our mother nature can take benefit from less leaded manure .

It is good that level of phosphorus can be decreased to 0.10 percent level, but what about calcium level. Is level of calcium also reduced? Secondly what was the energy content of the diet? Since ME of diet is related to AP content. Thanks.

is there a diffrent between coated and uncoated phytase in the activity

A good tool to reduce the phosphorus pollution but it should be mentioned that how much phytate phosphorus in the trial rations because NRC 1994 depicts the available or Non-Phytate phosphorus level in layers at 80-120 grams feed is 0.31 to 0.21[percent] respectively. The detailed information about formulation and its nutrient should also be mentioned . At present era of advanced technology the companies manufacturing enzymes claim to adjust 0.1 [percent] available phosphorus from the phytase enzyme inclusion.Overall it is a good approach we have to consider as a trial to reduce the expensive inclusion of mineral soureces of phosphorus.

This is a good article and it confirms the use of phytase enzyme in commercial feed. It not only reduces the phosphorus contents in excreta but it also save a good amount of money.

This article also validates the need of Phytase enzyme use in commercial poultry feed.

Its a nice effort,I suggest more details should be given like the bone mineralization and tibia ash. Overall phytase supplementation restores performance and reduces the environmental demage.

data was exciting. i think increasing of egg production in second treatment than the third refers to side effects of phytase enzyme such as increasing of ME and availability CP and minerals and etc.

You can extract up to 0.12[percent] phosphorus by using a good quality phytase and this has been claimed by Danisco and they also claim there product to be heat stable at 95C.
