ARTICLE 88 FEED & ADDITIVE MAGAZINE November 2025 efficient, allowing a better absorption of the other nutrients in the diet; Therefore, considering the results reported by Ipharraguerre et al. (2009; Figure 1), the enhancements reported by Herrero-Encinas et al. (2022) might be attributed to this fact. IMPROVING NUTRIENT DIGESTIBILITY HAS AN IMPACT ON PERFORMANCE These beneficial effects on nutrients digestibility have an obvious and positive impact on the growth performance of the animals. A work published by Menoyo et al. (2021) compiled, in a meta-analysis, 8 experimental trials in broilers chickens in which the inclusion of Spicy was assessed on performance parameters in two different phases of the rearing cycle: starter phase (from day 0 to 21 of life) and grower-finished phase (from day 22 of life until day of slaughter) (Table 1). The results of the meta-analysis clearly indicate that the dietary inclusion of Spicy has a positive influence on growth performance, justified by its effects as nutrients digestibility enhancer, increasing the average daily gain of the animals during the entire rearing cycle and improving the feed conversion; thus, increasing the feed efficiency of the animals, particularly during the starting phase. CONCLUSIONS The combination of specific spices, present in Spicy, has functional properties as digestibility enhancer, increasing the absorption efficiency of the poultry gastrointestinal tract of lipids (fats and oils), as well as other nutrients and energy. This fact has a direct and a positive impact on broiler chicken’s growth performance, translated into higher body weight gain and better feed conversion. References 1. Aviagen. 2022.
