Nitrogen management in poultry industry from circular economy perspective

The intensive production and linear economy (LE) model utilisation in Malaysian poultry industry potentially lead to climate change. The negative impacts of climate change on poultry farming have attracted the attention of the government because it induces the need to have a transition from a LE mod...
