The focus of the research was to examine the effects of the addition of different concentrations
of bee pollen to broiler feed on production performance, microbiological composition
of caecum and carcass quality. The study was performed on 1200 chickens divided
into 5 groups with 6 replicates per group. During the test, the broilers were fed with
two complete feed mixtures (starter and finisher) each differed only in the amount of
pollen added: no pollen in control group (C); 0.25% pollen in feed consumed by P0.25
group; 0.5% in P0.5 group; 0.75% for group P0.75; and 1.0% of pollen in feed for P1.0
group. Body weight of the chickens was measured during the change of the mixture, on
the 21st day and at the end of the research (day 42). Average feed consumption, average
daily gain, feed conversion rate, mortality and European Production Efficiency Factor
(EPEF) were determined. At the end of the experiment, 12 chickens of both sexes were
sacrificed from each group, in order to... determine the microbiological composition of the
intestines and slaughter performance.
The results showed positive effects of pollen use on production parameters. Chickens
of P0.75 group had significantly higher (p < 0.05) average daily gains and better feed
conversion, also the value of EPEF was significantly higher (p < 0.01) in P0.75 group
compared to groups with lower pollen addition. A significantly higher (p < 0.01) number
of Enterobacteriaceae was found in the cecum content of chickens of C and P0.25 groups
compared to P0.75 and P1.0 groups. No significant differences in slaughter performance
were found. It was concluded that the addition of 0.75% pollen can have a positive effect
on the production performance and the microbiological composition of the intestine.
