In vitro fertilization in horses
Müller, Filip ; Šušor, Andrej (advisor) ; Šimoník, Ondřej (referee)
Reproductive management in horse breeding increasingly relies on in vitro fertilization (IVF) techniques. This technology entails a complex process, including the acquisition of immature oocytes, their in vitro maturation, fertilization with sperm, and subsequent cultivation of the early embryo before transfer into a synchronized recipient. However, the success of equine IVF is influenced by various factors such as oocyte quality, sperm capacitation, and technical issues unique to this process, compared to other mammalian models. This bachelor's thesis aims to summarize and evaluate current knowledge on IVF of horse eggs, identify key factors influencing success, and describe current procedures for gamete preparation. By incorporating the latest IVF approaches and optimizing them, a higher success rate can be achieved. Key aspects for improving equine IVF include gamete collection and handling, in vitro oocyte maturation, sperm capacitation, and subsequent embryonic development.

Analysis of ponies bred for sports performance based on results in international dressage competitions
Havlíčková, Kristina
This thesis aimed to evaluate the performance of sports ponies at the international dressage level based on the following factors: sports season, age, sex and breed. The basis of the database was the dressage pony ranking of the International Equestrian Federation from 2014 to 2020. Two analyses were performed, one for the whole population and the second for the top 10% of ponies of each season. Statistically significant impact was found in the sports season (p ≤ 0.05) and high statistical significance in age and breed (p ≤ 0.01). Sex was the only factor with no statistical significance (p > 0.05). Ponies achieved the best average results in the year 2019 (983.72 points). On average, the best age categories were 9-12 (968.91 points) and 13-16 (968.90 points). Stallions were the best-performing sex (975.28 points). Ponies of Dutch Riding Horse and Pony Studbook (1 040.70 points) and Danish Sports Pony (1 039.50 points) achieved the best point results. Only the sports season and breed in the top 10% of ponies showed statistical significance (p ≤ 0.05). Ponies earned the highest number of points on average in the year 2020 (1 873.80 points). The best performance was given by ponies aged 17 and higher (1 899.00 points), although this category contained only two specimens. Stallions earned the highest number of performance points (1 842.70 points), and the best breed was the German Riding Pony (1 828.20 points).
