Phosphorus (P) is an important major mineral element required by all livestock species. Dietary phosphorus can’t be fully utilized by monogastric species especially pigs due to several dietary factors. As a result, most of this mineral is excreted through faeces without utilization and is considered as economic loss as well has also environmental impact due to its excess release in the soil and water. The majority of oilseeds and meals used for ration formulation are phytate bound and unavailable to the animal. To overcome the problem various strategies have been developed and it includes dietetic addition of microbial phytase, giving low phytate diet and grains containing a high level of inherent phytase, oilseed meals, and the making of phytase-secreting transgenic animals etc. ‘Enviropig’ is a very recent biotechnological tool through genetic engineering technique that could process phytates and able to digest plant phytate phosphorus. It can produce enzyme phytase in their saliva so that the pigs can degrade normally dietary indigestible phytate. In the present manuscript, the authors discussed the potentiality of Enviropig and its scope in near future for eco-friendly pig production.
