Recent interest in how poultry are housed and managed in order to ensure profitability, sustainability, and good levels of animal welfare, are challenging issues that commercial poultry keepers face, particularly where legislation is bringing about legal requirements for housing. This book compares and contrasts alternative housing with conventional and traditional systems for commercial poultry (laying hens, meat chickens, turkeys, waterfowl and gamebirds) with regards to welfare, disease, health, nutrition, sustainability and genotype-environment interaction.

This book presents refereed and edited papers from the 6th International Symposium on Poisonous Plants, held in Scotland in August 2001. It covers a range of topics from plant biochemistry to toxic effects in animals (particularly grazing farmed animals) and humans. The contents include the evolution of antinutrients and toxins in plants, biomedical applications of toxins in plants, isolation, identification and effects of plant and fungal toxins and the effect of plant toxins on aversion to plants in animal diets.
