It is also known that dressed poultry carcasses are without internal organs, a head
(between the second and the third cervical vertebrae), a neck (without skin) – where
shoulder joints, the limbs to the metatarsus or below, but not more than
20 mm, with an internal fat. The weight of the broiler chickens’ carcasses of the first
experimental group at the beginning of the half-life period was by 17,4% higher than
the weight of the carcasses of the first control group, and the weight of broiler chickens’
carcasses of the second experimental group exceeded the weight of the carcasses of the
second control group by 15,6%.
The weight of the broiler chickens’ carcasses of the first experimental group at
the end of the elimination period was by 12,0% higher than the weight of the carcasses
of the first control group, and the weight of the broiler chickens’ carcasses of the second
experimental group was by 14,7% higher than that of the second control group.
Slaughter yield of broiler chickens’ carcasses of the experimental group
(whichwere fed with pharmazin) was by 6,8% higher than in the first control group,
and the slaughter yield of poultry of theexperimental group (were fed with
tilotsiklinvet) exceeded indicators of the second control group by 2,1%. At the end of
the withdrawal period, the slaughter yield of broiler chickens’ carcasses of the first
experimental group was by 1,4% higher than that of the first control group, and the
difference in the slaughter yield of the bird of the second experimental group was
2,2%, as compared to the control.
To determine the functional load on the internal organs of broiler chickens, they
had analyzed the ratio of the edible internal organs weight to the slaughter yield
(Tables
5, 6).
