The study was carried out to see the effects of
carcass traits on slow growing broilers in free range system. In the
experiment, 480 slow-growing male Hubbard Isa Red-J broiler chicks with 28th
days age were divided into 4 main groups and 4 subgroups in each main group. In
the experiment, feed was given ad libitum to the control group (group 1). 2th,
3th and 4th groups were fed %75, %50, %25 of food consumed by control group. The
chicks in the experimental groups were released to the pasture between at 7:00
- 19:00. Chicks in the experimental groups were fed with alfalfa, unbranched
bromine and thyme grass on free range area. At 42 and 84th days, 128 chicks
taken randomly and equally from each group were slaughtered to examine carcass
traits. In terms of most of carcass traits; even though similar results were
seen between %75 restricted groups and control group in 42th, significant
differences were sharpened among control and treatment groups in 84th day. It can
be concluded from this study that carcass traits of slow growing chickens were
affected by feed restriction especially at 84th slaughter age.
