Описание
With the beginning of new millennium most of the countries producing grain and seeds (maize and soybeans) moved to change its policy from exporting the surplus to the third world countries to the production of clean energy (ethanol). This has led to significant shortfall in the quantities imported in these consuming countries for these grains, which in turn led to an increase in the prices of the feedstuffs for livestock and chickens and thus a significant decrease in the production. So it was necessary for the third world countries to look for other alternative available locally sources of protein and energy especially from their own products such as poultry slaughterhouse by-products to feed their poultry. Although it has been the completion of this study in the 1998, but the researcher was able to predict this to happen and was able to search and find suitable alternative locally produced sources of protein instead of other traditional sources to be used in poultry rations.
