Assess the current state of nutrition of horses in the specific stables and proposal optimal doses according to the their performance
Burcalová, Helena ; Mudřík, Zdeněk (advisor) ; Václav, Václav (referee)
This work deals with calculations of feed rations of selected thoroughbred horses at the High School of Horse Racing in Prague together with an assessment of economic aspects of horse feeding. The school is mainly focused on the education of jockeys, which means that the work with horses has to conform to the school requirements that need not meet the ideal feeding rhythm of the horses.
United Kingdom norms were compared to the selected Czech norms. Focus was mainly on the racing season, which provides direct comparison of the feed rations with the horses results in the races. The racing season has the highest energetic requirements that need to take into account not only the requirements for the races themselves but also for the resting periods. Feed rations were measured and fed in precise time intervals. Main feeds were oats, hay, bran and Spillers feeds.
During the assessment period a negative side - effect of high temperatures during consecutive heat - wave periods was observed. This aspect may prove important in the future and needs to be taken into account not only for feeding but for the entire horse training.
Out of five examined horses, exceedance of digestible energy requirements was observed with two horses and underestimation with one horse. For two of them the anomaly was in norm. However, the horse with the highest exceedance was experiencing difficulties with feeding, always leaving a part of the ration intact. This made it necessary to adapt the rations to a higher figure than calculated.
Economic aspect of horse feeding needs to be taken into account. The feeding expenses can be decreased by a suitable selection of a feeding mix, however the savings in this regard are not fundamental.

Evaluation nutrition of horse today at a time when the horse becomes the subject of a pets breeding
Nápravníková, Eva ; Mudřík, Zdeněk (advisor) ; Jiří, Jiří (referee)
The master's thesis describes evolution of horses, its domestication and coexistence with humans. The hypothesis is that 'The common used feed portions in hobby breeding programmes don't correspond to true need of nutrition established according to the horses actual sport performance'.
The horse is a non-ruminant herbivore, whose digestion of fiber is based on its fermentation in the colon. Therefore there are certain limitations and requirements for the feeding technology and the composition of the feed for individual horses. The transfer of the matter through the digestive tract and absorption of nutrition in each part of the digestive tract.
The next part of the thesis concentrates on metabolism during physical work, adaptability to training and physiology of training. There is a part focused on utilization of energy from feed, where the difference between an anaerobic and aerobic metabolism is described.
To accept or decline the hypothesis, three horses with different equestrian use were chosen. The first was a Welsh Part Bred (WPB) pony mare competing in pony show jumping at L level. The second was a Czech warmblood (ČT) mare competing in both show jumping and dressage at L level. The last was a WPB pony mare used for hobby riding. For all three horses, the nutrition values of feed rations was calculated for the reporting period. These were compared with the true requirements of each horse according to their physical work. It was established that the selected horses were not fed according to their actual sports performance.
Therefore the hypothesis was confirmed. The found data was transferred into a graph form for ease of evaluation. Where there was a higher fluctuation in the value of the feed portions, it was pointed out the danger to horses with long term feeding of unsuitable feed portions.
The master's thesis shows to the owner of horses used in hobby breeding with the need to build the feed portions according to real physical work of their horses. The use of wrong feed portions and feed technology can cause health problems with long term effects.
