This diploma thesis contains a brief history of goat breeding and its numbers in the world and in the Czech Republic. It also deals with the importance of colostrum for kids, its structure and the factors that in uence it. The aim of this thesis was to analyze the microbiological quality of goat colostrum from the individual sample collections realized on seven farms in February 2017 and to assess the in uence of the farm, breed and freezing. At the time of sample collection, the animals were housed in a stable in an individual birth box and were fed an intensive diet. The individual samples of colostrum were chilled or frozen and then transported for laboratory tests at the Veterinary and Pharmaceutical University in Brno. The microbiological analysis was focused on the total plate count (TPC), the presence and amount of Escherichia coli, verotoxigenic Escherichia coli (VTEC), Staphylococcus aureus and its genes encoding staphylococcal enterotoxins. Data analysis suggests that the most common pathogenic microorganism on farms is Escherichia coli, while VTEC has not been detected in any sample. Among the observed indicators, the Staphylococcus aureus was found most often. For the total number of microorganisms and pathogenic microorganisms, the lowest incidence was observed in farm no.5 with an average TPC of 162,250 CFU/ml and Escherichia coli in a single sample of 20 CFU/ml. The farm with the lowest microbial quality of colostrum was identi ed as a farm no.1 whose TPC was not the most numerous: 130 166.7 CFU/ml, but the incidence of pathogenic microorganisms was the highest out of all samples: Escherichia coli 250 CFU/ml and Staphylococcus aureus 780,000 CFU/ml. Based on the results, Farm no.1 was adviset with the possibilities of how to improve the animal hygiene to raise the microbial quality of colostrum. The in uence of the breed was not explicitly determined, however, the highest quality colostrum was obtained from the crossbreeds of the following breeds: white shorthair goat, short-haired goat and Anglonubian goat.
