Moringa oleifera and Morus alba leaves are nutritious non‐traditional feed ingredients containing bioactive substances. This study was to evaluate the potential application of dietary Moringa and Morus leaf powder on the growth traits, carcass characteristics and meat quality of finishing pigs. Moringa did not alter growth performance or carcass characteristics, but it decreased meat b* value, increased MyHCIIa and decreased MyHCIIx mRNA levels, and increased CP and concentrations of Ala, Thr, Ile, Lys and Pro in longissimus thoracis. Morus increased final BW, ADFI and ADG, decreased F/G ratio, improved slaughter weight, carcass weight, carcass yield and meat a* value, and decreased shear force, drip loss, MyHCIIx and MyHCIIb mRNA levels, and increased MyHCI and MyHCIIa mRNA levels. Morus also increased CP, Glu, Gly, Ala, Arg, Ile, Phe, Pro, Ser, Tyr and Asp, and C16:1, C18:1n9c, C20:4n6, C18:3n3, C20:3n3, C22:1n9 and n‐3 PUFA, but decreased C12:0 and C16:0. In summary, Morus improved the parameters and held great potential as an unconventional feed crop.

日粮中添加辣木和桑叶对育肥猪猪肉品质的影响

辣木和桑白皮叶含有生物活性物质的营养非传统饲料原料。本研究旨在评估日粮辣木和桑叶粉对育肥猪生长性状、胴体特性和肉质的潜在应用。辣木没有改变生长性能或胴体特征，但它降低了肉的 b* 值，增加了MyHCIIa和降低了MyHCIIx mRNA 水平，并增加了胸最长肌的CP 和 Ala、Thr、Ile、Lys 和 Pro 的浓度。桑增加最终体重、ADFI 和 ADG，降低 F/G 比，提高屠宰重量、胴体重量、胴体产量和肉 a* 值，降低剪切力、滴水损失、MyHCIIx和MyHCIIb mRNA 水平，并增加MyHCI和MyHCIIa mRNA 水平. Morus还增加了 CP、Glu、Gly、Ala、Arg、Ile、Phe、Pro、Ser、Tyr 和 Asp，以及 C16:1、C18:1n9c、C20:4n6、C18:3n3、C20:3n3、C22:1n9 和n-3 PUFA，但减少了 C12:0 和 C16:0。总之，桑属改进了参数并具有作为非常规饲料作物的巨大潜力。
