Vliv bezobilné komplexní krmné směsi k výskytu toxémie u morčete domácího
KOPOROVÁ, Lenka
This diploma thesis is focused on the observation of the influence of nutrition on the presence of toxemia, the birth weight of young and their viability in domestic guinea pigs. An observed breeding of animals was determined, which was first given a commercial feed mixture containing grains. Subsequently, the breeder decided to make a change and switched to grain-free feed. All values were carefully recorded during the monitored years and then compared with each other. Great emphasis was placed primarily on the results of the occurrence of toxemia in pregnant females, as the hypothesis of today's professional literature, which increasingly points out that we can prevent this disease in guinea pigs by giving grain-free feed, was to be confirmed. The results showed that diet does not have a big effect on how many newborns are born during one gravidity and how many of them die during the first days of life. However, the feed, for example, influenced the birth weight of the guinea pigs, as the feed containing grains resulted in larger newborns being born overall. A significant influence of the animal's diet was observed in the occurrence of abortions and toxemia in females, when after the transition to a new grain-free diet, these problems completely disappeared.

Vliv výlisků ostropestřece mariánského v krmné směsi brojlerových kuřat na sensorickou jakost masa
Sedláčková, Kateřina
The aim of this diploma was evaluate the effect of feeding milk thistle (Silybum marianum L.) seed cakes on sensoric quality of broiler chickens meat. The experimental groups of broiler ROSS 308 received feed mixtures containing 0 % (C - control), 5 % (MT5) and 15 % (MT15) of milk thistle seed cakes. The chickens were fattened on conventional deep litter system. The trial lasted 37 days. Sensory analysis of breast and thigh muscle samples was evaluated in special sensory laboratory (Department of Food Technology, Mendel university in Brno) according ISO 8589. Breast meat was significantly (P < 0,05) rated as the best in parameter flavour in C (control) and MT15 group. The thigh meat was evaluated significantly (P < 0,05) best for colour and fibreness parameters in MT15 group. The addition of milk thistle seed cakes do not worsened sensory characteristic of breast or thigh meat of broilers and reflects standard sensory quality traits.

Výživa a krmení zakrslých králíků
Halouzková, Soňa
This bachelor thesis on the topic Nutrition and feeding dwarf rabbits I focused on general information about dwarf rabbits as zoological classification, history breeding and use of dwarf rabbits. Much of the work deals with the anatomy, physiology of digestion and absorption of nutrients, which is closely related to nutritional requirements. Further chapters relate directly to nutrition and feeding techniques. I dealt with the general characteristics of nutrients, methods of their determination and the need for individual rabbits categories. Then I said feed mainly suitable for dwarf rabbits and basic principles of feeding. All nutrient standards are established only for domestic rabbits, that's why I said in the last chapter experiment aimed at comparing nutrition claims in domestic and dwarf rabbits. The experimental part involves the preparation of feed mixtures, which I fed my own breeding dwarf rabbits, familiarity with local conditions and tested rabbits and the results of the experiment.

Posúdenie ekologického chovu oviec podľa typu výživy
Žišková, Katarína
In this thesis was the biggest focus on nutrition in rearing lambs after very early weaning on particular existing ecologic farm in the Spiš region on Slovakia. This thesis was focused on assessing the difference and suitability between two organic granular compound feed (starter), which were made to order. Feeding mixtures consisted of a different representation of the same components, where the experimental feed had higher nitrogen substances (NL). To confirm this difference was conducted chemical analysis. In that year 80 lambs were weighed, and they were divided into two groups since 06.02.2014 to 23.05.2014. The average age of lambs after attempt was 104 days. The measured values were subjected to statistical evaluation of weight, weight gain and daily gain during the test, weighing and period of weaning from milk. Lambs achieved during the test total increase of weight gain in the experimental group 17.9 +- 0.252 kg and 20.75 +- 0.775. Average daily weight gain by the end of the experiment was 0.17 kg in the experimental group and 0.202 kg in the control. Their growth (y) was expressed by two regression equations for test y = - 0.0002x2 + 0.1923x + 2.6564 (R2 = 0.998) and control group y = - 0.00012x2 + 0.2139x + 2.5567 (R2 = 0.999). Our results show demonstrable differences between lambs fed with different feed mixture. In the control group EKO BK3 with the original compound feed had lambs all results better than the experimental group ECO START OVIS, despite the higher content of nitrogen substances in compound feed.

Vliv rozdílné techniky aplikace krmiva na produkci kapra obecného (Cyprinus carpio L.) v rybničních podmínkách
Weiser, Tibor
The aim of this work was to evaluate and compare the effect of the Carp - Feed feeding system with the feeding by standard way "by hand" at different densities of fish stock (2000 - 6000 pcs per ha) of common carp (Cyprinus carpio L). In the period of 24.4. -- 27.9. 2012 feeding tests in rearing of carp fry (mirror carp) in the ponds system in Milevsko were conducted. The feed mixture with the increased content of nitrogenous compounds at the level of more than 18% was used in the test. According to results, increasing of individual growth was found at 197 g (45%), resp. 52 g (25%) in the higher stocking density when using the Carp - Feed, which is caused by increased growth intensity by 6.1, resp. 2.2% in the relative daily growth and by 0.22%, resp. 0.044% per day in SGR. The production efficiency of food fluctuated in the range of 0.95 - 1.86 in FCR, 0.54 - 1.05 in FCE, 0.45 - 0.92 in FCR / SGR and 1.774 - 2.311% per day in specific growth rate SGR. The influence of feeding method and stock density on length and weight parameters, exterior and on chemical composition of muscle was statistically significant (P - 0.05). There was not proved any significant influence on fitness indicators. According to the observed results, it is suitable to use the Carp-Feed feeding system, but higher food consumption and lower individual weights at higher densities of fish stock have to be considered. That is why the aim of rearing should be set in advance. According to experiment, it is better to choose higher stock density (6000 pcs per ha) when using the Carp -- Feed for reaching the higher production in acceptable individual weight and for maximum yield. The literary review on feeding problems and possible modification of feed is also part of this thesis.
