Together the pig and poultry industries produce more organic by-product than beef feedlotting in Australia. The composition of the by-product depends mostly on the production system used - in particular, the manure management practice. An increasing number of egg producers are using barn or free-range methods where the manure is mixed with a bedding material and is removed periodically. Broiler chickens are also raised in barns and the litter (manure and bedding) is removed at the end of each production cycle. Broiler production is by far the larger of the two poultry industries, producing more than one million tonnes of organic by-product a year.
