Popis: A study of the safety of the use of feed additive Liaform for the target species – broiler chickens. Liaform is a yellowish liquid with a specific odor. The feed additive contains lactic acid, formic acid, sodium formate, propionic acid and water. Given the composition of the additive, it can be attributed to two functional groups: preservatives – substances or microorganisms that protect feed from damage by microorganisms or their metabolites, acidity regulators – substances that regulate the pH of feed. For the study was formed on the principle of analogues of 3 groups of broiler chickens of 15 heads (control and 2 experimental) from 8 days of age. Feeding of chickens of the control group was carried out by standard complete feed. Feeding of chickens of the first experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg, feeding of chickens of the second experimental group was carried out with standard complete feed, in which feed additive Liaform was applied in 10 times the recommended dose of 20 g/kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It was found that the studied feed additive in 10 times the recommended dose does not have a negative impact on productivity, growth and development of broiler chickens, feed absorption. As a result of the use of Liaform feed additive in 10 times the recommended dose, the live weight of broiler chickens in the experimental group was higher compared to the control and lower compared to the recommended dose. The use of a feed additive in 10 times the dose did not have a negative effect on hematological parameters and serum protein levels, did not cause a negative effect on the condition of internal organs.
