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. |
