Three experimental groups were evaluated: the first one (negative control, NC) with a low nutritional value diet (2317 kcal/kg NE), the second with low nutritional value diet supplemented with the phytogenic mixture (NC+PHYT), the third group (positive control, PC) was fed with a high nutritional value diet (2365 kcal/ kg, +48 kcal/kg vs. NC). As presented in figure 2, during the fattening period the pigs fed the phytogenic mixture observed significantly higher (P< 0.0001) growth performance in comparison to NC group (+6.1 average daily gain, - 6.6% feed conversion ratio) and it showed comparable values to the PC in the same period of the study till slaughter (Samson et al., 2023). This confirms that phytogenics can improve feed efficiency in fattening pigs and may compensate for the reduced nutritional value of the diet. This specific combination of phytogenics showed to be an effective tool to increase the energy available for growth performance and to optimize the feed formulation costs. In ADM, we use state-ofthe-art technology to deliver high-quality end products and meet customer needs. Our phytogenic bioactive-based products consist of a combination of finely selected substances found in aromatic plants and spices, encapsulated in a fat matrix for greater stability and application. In addition, phytogenic molecules have proved their effectiveness without involving risks to animals, consumers or the environment (Gharib et al., 2014). FINDING THE IDEAL BALANCE BETWEEN FEED COST AND FEED EFFICIENCY Gut health is a multifactorial and complex topic, depending on the environment, farm management, feed and housing changes. It is also probably the greatest concern for meat producers because of its impact on growth performance, animal welfare, economic sustainability and a consumer concern about food safety and traceability.

Effect of a standardized blend of cinnamaldehyde, capsicum oleoresin and carvacrol (PHYT) on the zootechnical performance in fattening pigs fed a low nutritional value diet. NC = low nutritional value diet, 2317 kcal/kg NE NC + PHYT = low nutritional value diet supplemented with the combination of phytogenics (2365 kcal/kg, +48 kcal/kg vs. NC) PC = higher nutritional value diet, 2365 kcal/kg NE, +48 kcal/kg
