The poultry industry is growing fast due to its high productivity and good returns. High productivity in turn is achieved by adopting better genetics and bringing about improvement in nutritional and managemental practices. All these though come at a price. It reduces the bird’s ability to sustain stress.
With the nutrients demand always being high, where things aren’t managed well, it affects the bird’s health adversely making them morbid  which shows itself in a marked decline in production, and consequent economic losses. In that sense the poultry industry is like a double-edged sword. One mistake and you could end up with huge losses.
