title: Vitamin and trace mineral withdrawal effects on broiler breast tissue riboflavin and thiamin content.
abstract: An investigation was carried out to determine whether a Day 28 to 49 dietary vitamin, trace mineral, and vitamin plus trace mineral premix withdrawal would impact Pectoralis major thiamin or riboflavin concentration in chicks reared under thermoneutral (24 C) and heat-stressed (24 to 35 C) conditions. No significant (P > 0.1) environment by nutrient withdrawal interactions were detected. Heat stress and vitamin withdrawal reduced (P < 0.05) P major thiamin and riboflavin concentration. In contrast, trace mineral withdrawal failed (P> 0.1) to impact either vitamin. In conclusion, results from this study suggest that a 21-d vitamin withdrawal and heat stress exposure have the potential to reduce muscle riboflavin and thiamin concentration.
