The factors affecting the progress towards intensive livestock production are reviewed with particular reference to milk, beef, lamb, pork, bacon, poultry, meat and egg production. The future trends for the further development of intensive production in each class of livestock are considered and the genetic, managerial and economic constraints are briefly discussed. The different systems of management and housing of the various livestock classes are reviewed and the relevance of each system to the production of effluent is described. The reasons for the trend towards greater control of the animals' environment are listed. Finally, the concept of “stocking density” is considered in respect to the problem of pollution in intensive animal production systems and the possible implications of removing all forms of “animal pollution” are placed within the context of the other requirements for food production involving domesticated animals.
