The efficacy of an acidifier in the liquid form and the same composition on the special carrier Sequential Release Medium (SRM) (Biotronic SE forte) was investigated with broilers. Ross broilers (612) were divided into three treatment groups with 8 replicate pens per treatment. One group received 3 kg of the liquid formic and propionic acids per ton of feed, the second group was fed the same combination on SRM and the third group did not recive any feed additives. Chicks were kept in stressing conditions: reduced ventilation, recycled litter, and higher temperature (>29○C) from hatch to 24 days of age. Birds fed acids in a liquid form were numerically 3.2% heavier in comparison to the control group (P>0.05), while the group fed acids on SRM were 4.9% heavier than control (P<0.05).
European Production Efficiency Factor (EPEF) was improved by 15% (P>00.05) and by 21% (P<0.05) in birds fed the organic acids in liquid form or on SRM, respectively. In conclusion, acids on SRM carrier improved performance of broilers better than acids in the liquid form in less than optimal environmental conditions.
