Abstrakt
Technological stresses affect the productivity of broiler-type chicken and are related
directly to poultry farming intensification. Heat stress occurring in conditions of high density
keeping, especially at high summer ambient temperatures, is very important. Stress factors
influence the metabolic processes in poultry, while reducing the production parameters of
operation and, by extension, the efficiency of broiler farming.
The objective of this research was to identify the efficiency of a feed supplement in alleviating
technological stresses in poultry industry.
Use of supplement (the preparation contains succinic acid, L-carnitine, betaine, inorganic salts of
zinc, manganese, copper and lithium) preserved the production performance of broiler-type
chickens in the pre-slaughter period, by reducing the technological load on the poultry body, as
it was indicated by an increase in the efficiency of fattening by 16.2 conditional units, meat yield
by 1.4%, gross income by 49.2% and a decline in mortality rate by 1.5%. The data on production
efficiency indicators of broiler feeding were obtained on a large sample - 6136 heads.
