Chuťové preference králíků při krmení obilovin s různou barvou obilky
Novotný, Jakub
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.

Porovnání krmných dávek s různým obsahem antokyanů ve výživě králíků
Metnarová, Eva
In this thesis the need for nutrients for rabbits was described. Anthocyanins were described as biological substances contained in wheat with non-traditional coloring and their possible antioxidant effects. The second part of the review is devoted to bio-chemical parameters of animal blood. The practical part was aimed at the study of the influence of feed mixture with increased content of anthocyanins. In the experiment, a wheat species PS Karkulka with purple pericarp was used and Vanessa was used as control wheat species. Both of these made 15% of the feed diet. 18 rabbit females of which 9 were in the experimental group and 9 in the control group were included in the experiment. They were fed a complete pelleted mixture. In the experiment, the weight of the animals, the average weight gains, the feed consump-tion, the feed conversion ratio were monitored. After slaughter, slaughter yield, bio-chemical blood analysis and antioxidant activity were monitored. The results show that the differences in average live weight were statistically in-significant, only at week 8 the differences in live weight was statistically significantly higher in the control group. Average weight gains were evaluated as statistically insig-nificant. Statistically significantly higher average feed consumption was found in the control group. The carcass weight was significantly higher in the control group. There were no statistically significant differences in biochemical parameters and blood anti-xodation activity.

Vliv sylimarinu na jatečnou výtěžnost králíků
KREJČÍKOVÁ, Klára
The work deals with the influence of the Milk thistle (used substance Silymarin) on the carcass yield of hybrid combinations rabbits Hyla. Hybrid combination Hyla was purposefully bred for meat performance, showing excellent results in breeding. Rabbits behave primarily on meat, because nutritional properties correspond to the current requirements of rational nutrition. Therefore, it is appropriate to increase the carcass yield. The average slaughter yield is indicated from 40 to 53% according to the breed. It was found that the addition of milk thistle in the form of a powder in the complete feedingstuff at a concentration of 0.2% increased the carcass yield, relative to the control group (which was fed only KKS), on average by 0.4%. The group with the addition of 1% showed an average value of 1.2% higher than the group control. The average slaughter yield of all the groups ranged from 54,68 into 63,02%. In both farms also decreased the incidence of diarrheal disease. Silymarin has a favorable effect on the operation and growth of the liver. In the group with the addition of 0.2% increased the average liver weight of 8.1 g, in the group with a concentration of 1% weight on average picked up about 10g. The average weight of the liver varied from 111,19 to 121,20 g. The control group in the case of carcass yield and liver weight showed better results than the authors of their articles.

Meat yield of rabbits
KREJČÍKOVÁ, Klára
This bachelor thesis deals with a topic of meat yield of crossbred rabbits. The basis assumption of quality of meat production, fur and rabbit skin is a sufficient nutrition as well as genetic disposal. The nutrition and feed depend on breeding and housing technology. Nowadays many types of feed exist. The most important fact in feeding is the time. It is necessary to gain the slaughter weight as soon as possible. In the first experimental group the slaughter weight (2600 g) was gained in 70th day of rabbit's life no matter if it was female or male animal. But in the second one the slaughter weight was gained after 77 days. The increases in weeks of feeding were equal, differences in the first groups were inconclusive, and in the second one there was a difference of 15, 5 g/week (2, 2 g/day) between female and male animals. The consumption of feed was different in those two experimental groups. In the first group there was no evidence of different volume of feed between female and male animals whereas in the second one the female animals consumed more feed than male animals. The difference was 4, 3 g/day. Silybum marianum was added to the feeding mixture in concentration 1, 0 % in the first group and in 0, 2 % in the second one.
