Introduction
Globally, domestic animals continue to make important
contributions to food supply. Livestock products account
for about 30 percent of the total global value of food and
agriculture, and approximately 19 percent of the value of
global food production (Heap, 1998). Products from food
animals provide over 33 percent of protein consumed in
human diets globally and about 16 percent of food
energy (Martin, 2001). However, despite considerable
progress in food production in the last 30 years, 800
million people in the world are still undernourished
(FAO, 1982).
Unfortunately, two thirds of the undernourished people
of the world are located in the developing countries such
as Africa. In these countries, daily protein intake is far
below the requirement. For instance, Africa is only
meeting 32g of the daily protein requirement of 52g
recommendation by FAO. FAO also recommended that
one third of the daily protein intake should be of animal
origin, but in Africa (especially Nigeria) only about 20%
of the low protein intake is of animal origin compared to
about 70% in the United States. According to Atteh
(2003), the average African is meeting only 33% of his
daily animal protein requirement while meeting 66% of
his daily plant protein requirement.
