Vliv přídavku quercetinu na výskyt kokcidií u králíků
Dvořáčková, Nikola
This thesis investigated the effect of the flavonoid quercetin on the coccidiosis oocyst counts in rabbits. At the same time, it also investigated the impact on weight, daily gains, feed conversation ratio, daily and total consumption, and biochemical blood parameters. The experiment lasted a total of 116 days. Two groups of six piece weaned rabbits each of the Japanese rabbit breed were created. The age of the rabbits was 35–149 days in the experimental group and 31–145 days in the control group. The average weight of rabbits at the beginning of the experiment was 267 g, and at the end, it was 2288 g. A special feed mixture containing 1.9% quercetin was prepa-red for the experimental group. The mixture was added in the amounts of 1, 2, and 4 g per day, depending on their equal weight. The addition of 0.01 – 0.04 g/rabbit/day of the flavonoid quercetin did not have a negative effect on the health status, performance parameters, and biochemical para-meters of the blood. The experimental group had a lower average number of oocysts (EPG) than the control group (quercetin = 328, control = 640). There was a statisti-cally significant effect of quercetin on the number of coccidia oocysts (P < 0.05), pro-bably through its antioxidant effect, supporting immune reactions, and thereby main-taining a healthy intestinal environment. Quercetin can be a potential substance for the prevention of coccidiosis.

The thesis compares the structure of feed mixture and the feed residues after the feeding broilers rabbits Hyla. There were made two different feed mixtures – the control one and the experimental one. The experimental feed mixture contained 10 % of purple grain wheat called PS Karkulka. In the control one was used 10 % of wheat Vanessa with classical colour of grain. The feed mixtures and the feed residues were separated on different wide sieves to find the size share. Than the feed mixture and the feed residues were compared. The quantity of parts bigger than 2 mm in the feed residues decreased and the quantity of parts smaller than 2 mm increased. Both with statistical significance (P<0.05). To detect the taste preferences between PS Karkulka and Vanessa the parts bigger than 2 mm in both types of feed residues were separated to individual components and compared. There was found that rabbits preferred the colored grained wheat (PS Karkulka) more than the classical one (Vanessa) with statistical significance (P<0.05). The next part is about performance parameters. The weight gain, carcass weight, carcass yield, feed consumption and feed conversation ratio were evaluated. In all of that parameters there were not found statistically significant differences (P˃0.05) between control group and experimental group.
