“…Previous studies indicate an active/inactive SC dietary supplementation improves broiler growth performance [11,17,18], immunity response [13], carcass yield [17], and meat quality [19,20]. Scientific evidence for using RM on broiler chick feed is very limited [21], but recent studies suggest that it could have growth promoting, health promoting, and production quality effects on laying hens [22], fish [23], and swine [24].…”

The utilization of synthetic additives (vitamins, proteins, and pigments) in broiler chicks’ feeds may cause problems in the future, such as competitive availability, extra productive induced costs, and human health risks relayed on sole ingredients commonly used on human and animal food and feeds. A total of 320-day-old broiler chicks were randomly assigned to eight experimental groups (a four × two factorial design), receiving two dietary yeasts, lyophilizate lysates yeasts:brewer’s spent yeasts: Saccharomyces cerevisiae (SC: 0, 0.6, 1 and 1.3 g/kg) and Rhodotorula mucilaginosa (RM: with 0.3 kg/t or without), during a 42-day trial. The broilers’ 24 h post–slaughtering performance, meat quality (pH, color, proximate chemical composition, texture profile analysis), and meat sensorial evaluation were performed at the end of the trial. Dietary SC supplementation had a significant effect on fat deposits (p < 0.05), thigh meat protein content (p < 0.05), and breast meat lightness (p < 0.05). Meanwhile, RM dietary supplementation positively affected all meat color parameters (p < 0.05). Considerable interactions (SC × RM) were obtained on the broilers’ breast and thigh meat moisture and yellowing index. Dietary lyophilizes lysates yeasts supplementation had an effect on meat color and proximate chemical composition. Furthermore, investigation is needed to elucidate the effects of microbial pigment supplements on broiler meat biochemistry and its pigment metabolism.
