The weight of the liver of broiler chickens of the experimental group – fed with
pharmazin – at the beginning of the withdrawal period was by 20,4% higher than the
weight of the liver of the of the first control group. And the weight of the liver of broiler
chickens of the experimental group– fed with tilotsiklinvet – was by 15,8% higher than
in the second control group. After the elimination period, the weight of the liver of
broiler chickens in the first experimental group was by 16,3% higher than the weight
of the liver of birds of the first control group, and the weight of the liver of broiler
chickens of the second experimental groupwas by 16,4% higher, compared with the
second control group.
The weight of the liver of the broiler chickens of the first experimental group,
relative to the slaughter yield, was by 4,5% higher than the weight of the liver of the
first control group at the beginning and at the end of the withdrawal period. The weight
of the bird's liver in the second experimental group and the second control group
relative to the slaughter yield was 2,05% at the beginning of the elimination period. At
the end of the withdrawal period, the weight of the liver of broiler chickens of the
second experimental group relative to the slaughter yield exceeded the weight of the
liver of the bird of the second control group by 1,4%.

In our opinion, an increase in the absolute weight of the liver of broiler chickens
is due to the fact, that the metabolism of tilozine flows mainly in the liver and the
highest concentration of antibiotics is achieved precisely in the liver, because it is
involved in the elimination of antibacterial substances in a body.
