| description |
By the late 1960s, poultry production had developed from a small-scale rural
enterprise to an economically important branch of agriculture. Flock sizes
increased and production systems, for hygienic and economic reasons, became
more intensive. Rearing and housing of laying hens took place in conventional
cages. At the same time, public concern for intensively housed birds began to
increase, particularly following publications such as Animal Machines written
by Ruth Harrison in 1964. New animal protection laws came into force and
agriculture was forced to adapt to the welfare concerns of consumers.
Alternative systems for housing laying hens that provided greater freedom of
movement and facilities for natural behaviour including the use of the third
dimension (perching, nesting) were developed. Production systems for meat
birds were introduced that, in addition to higher space allowances, specified
maximum rates of growth and feed ingredients. Time alone will show which
type of system for poultry egg or meat production will survive the evolving
social and economic pressures on producers and consumers. |
