用36头约克猪研究了在20~100 kg饲粮中添加高铜和VE对猪生产性能和猪肉品质的影响.试验采用2×2因子设计,在对照饲粮中添加250 mg/kg铜或/和200 mg/kg VE.结果表明,单独添加高铜或VE或二者同时添加有提高ADG、降低F/G的趋势,二者同时添加显著降低全期F/G(P<0.05).单独添加高铜趋于提高眼肌面积,不影响屠宰性能和肌肉养分含量,对冷存肉(4 ℃贮存)的滴水损失、硫代巴比妥酸反应物(TBA)值和肉色无明显影响(P>0.05).单独添加VE有提高眼肌面积和鲜肉肉色评分、降低鲜肉滴水损失和失水率的趋势(P>0.05),提高鲜肉Fe、Cu和VE的含量(P<0.05),降低冷存9天猪肉的TBA值(P<0.01)和滴水损失(P>0.05),稳定冷存猪肉的肉色达6~9 d(P<0.05).同时添加高铜和VE的作用规律与单独添加VE时相同,但作用程度略低于后者.本研究表明,在生长育肥猪饲粮中添加250 mg铜/kg对猪肉品质无不良影响,而添加200 mg VE/kg可改善猪肉品质,延长贮存期.
