This study aimed to evaluate the effect of partial uropygialectomy (PU) on carcass criteria and some blood parameters of broilers (ross-308). Two hundred, day-old, broilers were randomly distributed into five experimental groups of 40 chicks in four replicates, 10 chicks each. First group used as control (without PU) while, PU was applied on chicks in the 2nd (T1), 3rd (T2), 4th (T3) and 5th (T4) groups at 14, 17, 21 and 24 days of age, respectively. On the last day of the experiment carcass characteristics and some blood parameters were studied. Results indicated that the partial uropygialectomy did not have significant effects
on percentages of dressed carcass, breast, thigh, drumsticks, back, wings and
spleen. The highest abdominal fat% (P<0.05) was recorded for T1 group. Chemical
composition of meat was not significantly affected by PU at different ages. Studied
blood parameters were not significantly affected by PU, except plasma albumin
level which significantly (P<0.05) increased in T3, and cholesterol level which
was significantly higher in T4 compared with other groups. From the results of this
study, it could be concluded that partial uropygialectomy at 14 days of age for
broiler chickens achieved the highest performance and carcass traits.
Keywords: Broilers, Uropygialectomy, Blood parameters, Carcass traits.
