Environmental Aspects of Housing for Animal Production is concerned with environmental aspects of housing farm animals. The discussions are organized around physical and physiological principles; environmental influences on reproduction; environmental influences on the productivity of farm animals; optimal housing environments for temperate and cool climates; housing environments for hot climates; engineering and control of the house environment; and the constraints of welfare and disease.
This text consists of 32 chapters divided into nine sections. The first chapter explores the physiological mechanisms whereby the food- or fiber-producing animals maintain a constant body temperature under climatic extremes and the possible impact that these physiological processes may have on productive systems. This discussion is followed by chapters on the influence of climate on the decision to house livestock; the effect of the environment on animal reproduction; thermal influences on poultry; and the importance of ventilation and temperature control. This text also considers the poultry housing problems in tropical and subtropical climates; insulation of animal houses; and the interaction between feathering and egg production in laying hens.
This book will appeal to those working in the field of housing for animal production, both in research and development and at a practical level.
