Abstract

The world shortage of food is the most serious crisis which faces mankind today. It is a crisis which has no earlier precedent and one for which remedial measures will be hard to find. The problem, first mentioned by Malthus in 1798, is one of limited food resources combined with an increasing world population. The basis of food production lies in the soil mantle of the world which is limited in extent and decreases yearly both in quantity and quality through the use of bad farming practices which lead to soil erosin. The present level of human nutrition throughout the world is far from adequate. In North .America and Australasia, the average daily consumption of calories per head is above 3000 but in the Middle East it is only 2400 while in the Far East it varies between 1700 and 2100, which is well below requirements (Fawcett (1948)). Not only are these people in need of more food energy but they also require more protein, minerals and vitamins. Livestock products are, of course, rich in these 'protective' foods and the expansion of livestock production will play an important part in raising the level of nut­rition of the world's population.
