Pork continues to occupy an important position as a food source in affluent societies as well as in developing countries with slower economic growth. The growth of the world swine population continues at a faster rate than that of the human populatio

A dynamic herd simulation model for a swine production unit has been developed. The model is discrete and stochastic and the appropriate random distributions have been defined from the literature or empirically estimated. Theoretical concepts and rel

The shift in perspectives about livestock improvement over a 70-yr period is reviewed. The view changes from livestock improvement as an art, through its becoming a science, to its application as a technology in industry. The use of scientific tools

Fifty years of research in animal breeding and genetics are examined from four perspectives: 1) genetic prediction, 2) animal testing and selection schemes, 3) dissemination of genetic improvement, and 4) definition of breeding objectives in economic

Pork, along with other animal products, provides protein of higher nutritive value than that present in most plant proteins and also provides other nutrients not found in adequate amounts in plants. Pork supplies nearly one-half of the meat productio

In Chapter 3, it was stated that the genetic aspects of the production system set both the limits and potential for performance of the system. The breeding stock input into the system introduces potentials for animal performance but these are not usu

The evolution and domestication of the pig has been described in several books (Towne and Wentworth 1950; Mellen 1952; Briggs 1969; Mason 1969), and the student interested in a detailed account of this fascinating story is referred to them. Recorded

Some decades ago, “raising pigs” was primarily a subsidiary farm activity that took place in mud lots (Fig. 3.1), with minimal shelter, to utilize garbage and leftover grains to produce meat for the farm family. Pasture production systems (Fig. 3
