Výkrm býků pastevním způsobem v ekologickém zemědělství

The aim of the bachelor thesis was the analysis of meat performance of the herd of fattened bulls containing the majority of the Aberdeen Angus RED form. The fattening took place at 850-950 m a.s.l. in the organic farming regime. The set of bulls consisted of 23 bulls kept on the private farm. From the group of fattened bulls data about feeding quality and carcass values were obtained. The average live weight of weaned calves was 297 kg with the average age of seven months. The average slaughter weight of slaughter animals was 634 kg and the average carcass weight was 349 kg and the average carcass yield was 54 %. Significant differences were found within gains between the winter season and the grazing period when in the first winter period after weaning the daily gain was 0.36 kg per day and in the first grazing period was 0.66 kg per day. During the second winter period bulls reached the average gain of 0.45 kg per day and during the second grazing period of 0.64 kg per day
