Morphological evaluation of sperm has a long history and is an essential element analysis of semen, which provides breeders invaluable information to assess the health status of animal and its potential fertility. An important role is played by the percentage of healthy sperm due to abnormally developed. This value plays an important role in the usability of quality in breeding stallions. Stallion sperm intended for artificial insemination breeding mares in native form may not contain more than 40 % of defective sperm and the total amount of their activity should not be below 60 %. In the case of benefits intended for deep freezing is allowed only 20 % pathological forms of sperm. Activity selected for cryopreservation of semen should not fall below 80 %. The topic of the thesis was to determine the frequency of morphologic sperm defects in a group of stallions stud farm Tlumačov s.p., included in breeding season for 2013. Sperm morphology examination was performed on 72 samples of ejaculates collected from 12 stallions during the breeding season from May to August. For each stallion sperm activity was recorded of subjective method, immediately after collection, and the correlation was observed with respect to morphological abnormalities of the same sample. To investigate the morphological structure of sperm abnormalities were stained with two methods of cytological stain -- staining of B.T.Farelly and staining of Čeřovský. After staining the preparations were evaluated under a light microscope. Identified defects were divided into 6 categories - defects in the head, acrosome defects, defects of the neck, tail defects, abnormal forms of sperm and immature sperm. We studied a number of normospermia and total sperm pathology also expressed as a percentage. Another part of the analysis was a theoretical comparison of both the staining techniques with respect to suitability for the examination of morphological sperm abnormalities in stallions.

The theoretical part of the thesis on "Evaluation of semen quality selected breeds of dogs", provides a brief summary of available information obtained from literature dealing with dogs reproduction, anatomy male genital tract of the dog and basic laboratory techniques of animal semen analyzes. Practical work was focused on evaluating quantitative and qualitative parameters of ejaculate different breeds of dogs from the kennel Bohemia Alké. Was investigated primarily affect the order of collection, ages, body frame, time of day and length of the sampling collection itself on ejaculate volume, activity concentration, total sperm count and percentage of occurrence patomorfologických defects. Subscriptions ejaculate, macroscopic and microscopic evaluation was conducted in field conditions in the home where the dogs lived. To evaluate the percentage of damaged sperm pathomorphological were made morphological coatings, which were transported to the laboratory department reproduction of farm animals and the Institute of Animal Breeding, Faculty of Agronomy, Mendel University in Brno.

The task of the experiment was to confirm or reverse the positive and negative effects of mycorrhizal fungus on morphological changes in selected vegetable representatives. Its main part consisted of verification of these influences in the plant of concrete representatives, and other secondary experiments followed. Representatives for this task were Paprika Annual (Capsicum annuum) and Tomato Plant (Lycopersicon lycopersicum). The bulk of the verification took place at the Faculty of Horticulture at Mendel University in Brno. It has been found that the application of mycorrhizal fungus can influence certain quantitative parameters of selected vegetable representatives.
