Figure 2, "Composition of lean and fatty tissue", presents a diagrammatically the composition of a bacon rasher in terms of water, fat, and protein. The figure also shows a comparison of the amount of feed required to produce the fat and lean tissue components.

A 100 gram bacon rasher is shown composed of lean tissue and fatty tissue. The fatty tissue and lean tissue components are presented as diagrams indicating the proportion of their make-up that is water, fat, or protein. The fatty tissue is represented as being 20 grams, while the lean tissue is 80 grams, thereby making up the 100 gram bacon rasher.

The fatty tissue is composed of over three- quarters fat, about one-tenth water and the remainder protein. 80 grams of feed is required to produce the 20 grams of fatty tissue.

The lean tissue is composed of about two-thirds water, about one-quarter protein, and the remainder fat. 100 grams of feed is required to produce the 80 grams of lean tissue.

The 100 gram bacon rasher, therefore, requires 180 grams of feed in its production.

The point being made is that fatty tissue is relatively expensive to produce, in terms of feed requirements, compared to lean tissue.
