- Abstract
Broiler skin color plays a key role in consumer demand for food products in China and other Asian countries. Here the effects of natural lutein and two synthetic pigments, canthaxanthin (authorized) and orange-II (unauthorized), on the performance and pigmentation of broilers were evaluated. Histological changes in the pectoral muscles of broilers fed diets supplemented with various pigments were also examined. One-day-old chicks were randomly assigned into 10 groups according to dietary treatment and fed basal diets plus natural lutein,canthaxanthin and orange-II (25, 50 and 100 mg/kg) or control, respectively, over 7 weeks. There were no significant treatment effects on broiler performance and no interactions between treatment and gender found for any parameter (p> 0.05). Color analysis with a Roche Color Fan showed that pigmentation of chicken breast, vent and shank skin was significantly improved (p<0.0001) in canthaxanthin-fed chicks (25, 50 and 100 mg/kg), with higher pigmentation than the natural lutein and orange-II groups. More severe fibrosis was observed in broiler pectoral muscles in chicks fed the orange-II diet compared to other treatments and the control group by week 7 (p < 0.05). These findings argue against the use of unauthorized pigments in broiler diets.
