Abstract

The widespread use of antibiotic growth promoters (AGPs) in poultry production has contributed to the emergence of antimicrobial resistance, increasing the need for effective natural alternatives. The bioactive phenolic alkaloid present in Capsicum species has demonstrated antimicrobial, antioxidant, and digestive-stimulating properties. The present study aimed to evaluate the effects of a phytogenic additive derived from Capsicum chinense (oleoresin) on growth performance, survival rate, and breast muscle pigmentation in broiler chickens. A total of 2,400 one-day-old male broiler chickens with an initial body weight of 35.4 ± 0.43 grams were randomly allocated to 48 pens (50 chickens per pen) and assigned to four dietary treatment groups with 12 replicates each. The treatments included a basal balanced feed (BF) supplemented with 60 ppm of zinc bacitracin (T0). The second group received the BF with 300 g of capsicum chinense additives (ACC) per ton of feed (T300), the third group received the BF with 600 g of ACC per ton of feed (T600), and the fourth group received the BF with 1000 g of ACC per ton of feed (T1000). Growth performance parameters, including live weight (LW), average weight gain (AWG), feed intake, feed conversion ratio (FCR), and survival rate, were evaluated over a 42-day production period. At slaughter on day 42, breast skin pigmentation was evaluated using instrumental colorimetry based on the CIE Lab* system. The supplementation of Capsicum chinense significantly improved LW, AWG, and FCR during the first 21 days of age, with the best performance observed in Group T300 compared to the control group. Feed intake and survival rate were not significantly affected by the dietary treatments, although Group T600 experienced a lower survival rate. The current results indicated no significant differences in colorimetric parameters among dietary treatments, although Group T300 exhibited the highest redness (a*) values. The present findings indicated that supplementation with 300 g / ton of Capsicum chinense can improve growth performance in broiler chickens at 21 days of age, comparable to that of the group that received antibiotic growth promoters, without adversely affecting carcass pigmentation. © The Author(s) 2026.
