In discussing world supplies of grain for animal feeding, this has been interpreted in its broadest sense to include the seeds of oilseed crops, legumes (or pulses) and cereals. These, together with fish and animal protein meals, are the basic raw materials for the production of concentrated, or compound, feed which is conventionally associated with intensive livestock production. In his introductory remarks, the President warned against the dangers of generalization and this is particularly true when dealing with feed supplies, since the situation may vary considerably not only from one country to another but also from one region to another within a country. Nevertheless, it is not feasible to discuss detailed situations in a publication of this kind and the intention is to provide a general review of the overall situation.
