Cannibalism In Chicken

摘要

Many causal factors of cannibalism have been suggested - environmental, dietary and hormonal. Environmental conditions predisposing to cannibalism includes bright light or a poor distribution of light, high stocking density, too much heat, irritation from external parasites, feedrestriction and being without feed for a long time, insufficient nests and condition of floor litter of course. Calcium, protein, fibre and sodium chloride in insufficient quantities are the dietary origins of cannibalism using plant proteins alone in the formulated feed rather than animal proteins have been found to have more risk of cannibalism. Pellet feeding is more prone to feather pecking and cannibalism than feeding mash feed. Levels of estrogen and progesterone in blood when birds come to lay account for the increased risk of feather pecking and cannibalism.
