Rearing pull ets
Basic growth concepts - body weight
development & unif ormity
It is extremely important to follow ISA body weight
recommendations during the whole life of the birds. From
day old to transfer, the bird will grow slowly and organ
development occurs at various ages. A lack of growth
during a stage could have a detrimental impact on pullet
quality. Two birds with the same body weight haven’t
necessarily developed the same body composition. Good
growth curves lead to good pullet development.
