This study investigated the effects of incorporating 5% ground PN skin in the diet of broilers to assess whether PN skin supplementation would impact broiler meat quality metrics, potentially offering an alternative dietary supplement for broiler production. Ninety broilers were assigned to either a control diet or a PN skin-supplemented diet (5% w/w), with both diets matched for energy and protein content across 3 feeding phases. After 6 weeks, 15 birds per treatment group were evaluated for body weight, carcass traits, breast meat pH (measured at 15 min, 2 hr, 24 hr, and 2.5 mo postmortem), color, texture, thaw loss, cook loss, composition, and incidence of myopathies. Results showed that broilers receiving the PN skin diet had lower live body weight, carcass weight, and breast weight compared to controls (P < 0.05). No significant differences were observed in meat pH at 15 min and 24 hr, color at 24 hr and 2.5 mo, texture, composition, lipid oxidation (after 7 mo of storage), sarcomere length (after 7 mo), or myopathy scores (P > 0.05). However, pH was lower in the PN skin group at 2 hr and 2.5 mo postmortem (P < 0.05). Quantitative descriptive analysis indicated no effects of 5% PN skin on overall sensory attributes (P > 0.05), with reduced springiness and no evidence of rancidity, bitterness, or off-flavor development. Notably, the PN skin group exhibited reduced cook loss and thaw loss (P < 0.05), indicating greater water-holding capacity. In conclusion, 5% PN skin dietary inclusion slightly reduced growth performance but did not adversely affect key meat quality traits. These findings support the potential use of PN skins as a sustainable poultry feed additive.}, journal={Meat and Muscle Biology}, author={Munmun, Afsana Rahaman and Caceres, Jean C. and Sigmon, Christina S. and Tahir, Yabaiz and Vu, Thien and Walker, Lin and Toomer, Ondulla and Campbell, Yan L.}, year={2025}, month={Dec} }
