**2. Nonconventional feedstuff**

The rivalry between man and livestock, especially the monogastric for the conventional feedstuff, has led to the need of proffering alternative feed resources by using novel feedstuff that can complement the conventional feeds competed for by humans [18]. The essence of poultry production is to convert feeds not edible by man or excess feed resources into table eggs and chicken meat. The anticipated surplus of feed ingredients during the harvest period for poultry production could barely be sufficient for the increasing human population in Nigeria, thereby aggravating the competition between the populace and the poultry industry necessitating the need for inclusion of novel feedstuff in poultry feeding [19, 20].
