abstract = "of fattening broilers involves raising broilers on farms with a capacity of 5,000 to 50,000
units or more at a density of 0.06 m2 per bird. Modern poultry farms are constructed
with the task of reducing heat loss, i.e. improving energy efficiency, which very often
in combination with reduced ventilation can lead to increased levels of ammonia (NH3),
carbon dioxide (CO2) and other air pollutants, and thus adversely affect animal health
and productivity. The speed of gas emissions is influenced by many factors, such as the
composition of feed and the efficiency of feed use (conversion), the quality of the litter
and the microclimatic conditions on the farm. The litter on intensive poultry farms usually
contains 4 to 6% of nitrogen, most of which is in NH3 or NH4
+ form. The mixture
of litter and manure is a storage of nitrogen which is released in the form of ammonia
under appropriate conditions. On the other hand, the main source of carbon dioxide in
livestock is the product of animal respiration, so there is a connection between the levels
of animal metabolism and CO2 production on farms. The production of carbon dioxide in
birds is proportional to their metabolic heat production, and thus to the metabolic body
mass of the bird, which is affected by temperature and activity. The aim of the study
was to examine the effect of a nutritional supplement, Eubiotic, added to broiler feed on
the NH3 and CO2 emissions in a broiler farm. The values of NH3 and CO2 emissions in
the facility for breeding fattening broilers that received Eubiotic in feed were numerically
lower, which can be explained by better digestibility of basic nutrients, primarily
proteins, present in feed.",
