The objective of this experiment was to evaluate the impact of phytoadditives and fatty acid esters on heat-stressed pigs, focusing on final weight, average daily feed intake, average daily weight gain and health biomarkers. A mixture of short- and medium-chain fatty acid esters was used in the study (butyric, caproic, capric, lauric acid monoacylglycerol ester) with a concentration of 51% in combination with steroidal and triterpenoid saponins derived from Glycyrrhiza glabra (licorice), Quillaja saponaria (soapbark tree) and Trigonella foenum-graecum (fenugreek) are referred to as glycyrrhizin, diosgenin and quillaja saponins, respectively. The experimental group exhibited improvements in fattening parameters compared to the control group: final weight increased by 8.5%, weight gain increased by 10.2%, and feed intake increased by 4.9%. Additionally, the health status of the experimental group was affected, evidenced by a 15.6% increase in cortisol activity, a 44.5% decrease in haptoglobin levels and a 12.7% increase in heat shock protein-70 levels compared to the control group. These findings suggest that feed supplements comprising fatty acid esters and phytogenic substances can mitigate the adverse effects of heat stress, enhancing performance and health status of the organism.
