The human diet and poultry feed share common ingredients as both belong to monogastrics. The poultry meat cost increased
250 to 300 per cent due to increased feed cost. The feed cost for poultry production constitutes about 60-70 percent of
commercial poultry production. The competence for food ingredients between human and poultry makes the poultry feed
costlier than ever before. So, the poultry feed need some non-conventional feed ingredients, to make the industry survive and
provide the poultry meat at affordable cost. The major limitation of use of non-conventional low cost feed ingredients is because
of presence of certain anti-nutritional factors (AFNs) which could not be degraded in the digestive system of poultry birds. These
are responsible for problems like decreased rate of digestion, increased microbial activity in the gut, increased viscosity of fluid
phase in the intestinal content, decreased feed intake, decreased body weight, low feed efficiency, increased excreta moisture
etc. Some biotechnological tools like feed enzymes come in handy to address these issues. Few experiments demonstrated that
exogenous enzyme addition will act upon these and alleviate these harmful effects. These novel approaches will enable us to
overcome these problems and the use of appropriate enzymes in feed to breakdown the ANFs, which will ultimately yield more
energy, protein, minerals etc and improve the performance of the birds.
