This thesis deals with load of carbon dioxide on large and small farm, which is subsequently converted by digestibility coefficients of nutrients to the equivalent carbon dioxide. The objects of the calculation are two given farms, located in the Zlín Region. Small farm entertain with 15 pieces of pig sows in a closed herd turnover and large farm breeding cattle herds with a turnover of 100 dairy cows. From the sales of the pig herds on a small farm, I found a total feed consumption, which is 133.5 tons per year, which I calculated the carbon content received from the compound feed, which is 50.35 tons and 3.08 tons of nitrogen per calendar year. Pigs in the feces excrete 8.12 tons of carbon and 0.52 tons of nitrogen. Pigs consume 0.36 tons of carbon and 0.44 tons of nitrogen per ton of edible particles in the meat. To produce 1 kg of meat consumes 0.246 kg of carbon. On a dairy farm income in total 1,645.29 tons of compound feed per year in which they adopt 609.61 tons of carbon and 31.23 tons of nitrogen. In feces they excrete 156.84 tons of carbon and 8.05 tons of nitrogen. In the milk is eliminated 42.78 tons 2.51 tons of carbon and nitrogen. The herd turnover of 31 bulls with the increments 1.4 kg / day 210.53 tons annually consume feed mixtures from which bulls take 71.70 tons, and 3.21 tons of carbon. In feces they excrete 18.09 tons and 1.10 tons of carbon and nitrogen in the meat, at the slaughterhouse is excluded 4.49 tons 0.35 tons of carbon and nitrogen. At the turn of the herd of bulls with the increments of 33.7 1.7 kg / day annually consumes 265.49 tons of feed mixtures from which the bulls take 71.70 tons and 3.21 tons of carbon nitrogen. In feces they excrete 21.35 tons and 1.35 tons of carbon and nitrogen in the meat, at the slaughterhouse is excluded 4.88 tons 0.38 tons of carbon and nitrogen. To produce 1 kg of meat bulls consume 0.248 kg of carbon. In conclusion are recommendations to reduce emissions at the farm which is needed.
