The aim of the study was to evaluate the effect of feed containing faba bean on the physicochemical properties of breast and leg muscles. The study was conducted on 340 Ross 308 broiler chickens reared for 6 weeks. The control group received feed based on soybean meal. The treatment group received a feed mixture with faba bean as the source of protein. Different sources of protein in the diet were also associated with changes in the content of n-6 fatty acids (C16:0, C22:4) and the n-6/n-3 ratio in breast muscles, which was higher (P < 0.05) in treatment group. The collagen content was higher (P < 0.05) in breast muscles from control group. The study revealed that the use of faba bean as a substitute for soybean meal had no significant effect (P > 0.05) on water holding capacity, drip loss, or major chemical components of breast and leg muscles. The P/S ratio, AI and TI, and the content of cholesterol in breast muscles were comparable (P > 0.05) in both groups. The values of lightness (L*) for leg muscles were lower (P < 0.05) in treatment group. The use of faba bean instead to soybean meal in diets for broiler chickens had positive effects on meat quality traits.
本研究旨在评估以蚕豆为饲料源对胸肌和腿肌理化特性的影响。研究对象为 340 只饲养 6 周的 Ross 308 肉鸡。对照组接受以豆粕为基础的饲料，处理组接受以蚕豆为蛋白质源的混合饲料。饮食中不同蛋白质源也与胸肌中 n-6 脂肪酸（C16:0、C22:4）和 n-6/n-3 比值的变化有关，处理组中这些值更高（P<0.05）。对照组胸肌中的胶原蛋白含量更高（P<0.05）。研究表明，用蚕豆代替豆粕对胸肌和腿肌的持水能力、滴水损失或主要化学成分没有显著影响（P>0.05）。两组胸肌的 P/S 比、AI 和 TI 以及胆固醇含量相当（P>0.05）。腿肌的亮度值（L*）较低（P<0.05）。在肉鸡日粮中用蚕豆代替豆粕对肉质特性有积极影响。
