Halloysite supplemented in the diet, and sex of Cherry Valley ducks affects growth, carcass composition, meat quality, and jejunum and leg bone strength

Halloysite adversely impacted ducks' body weight and weight gain while altering meat quality by increasing pectoral muscle pH (pectoralis major) and fat content (pectoralis major and pectoralis minor) and changing leg muscles' color. Jejunum tensile strength was higher post-halloysite supplementation. These results suggest halloysite has both positive and negative effects on duck growth, meat properties, and jejunum strength, warranting further research.
