摘要 为了弄清复合脂肪中的高卵磷脂和必需脂肪酸对改进繁殖母猪生产性能的功效。选择妊娠85 d母猪(长白×大白)24头,随机分为2个处理。研究结果表明:妊娠后期和泌乳期母猪日粮添加复合脂肪,能提高断奶仔猪体重(P<0.05),有提高产仔数(P=0.09)和断奶活仔猪数(P=0.08)的趋势,以及降低弱仔数的趋势(P=0.10)。同时,复合脂肪的添加,减少了母猪皮屑、改善了毛色亮度,减少了便秘。母猪妊娠后期日粮使用1.5%复合脂肪,泌乳期使用3%复合脂肪,替代等量大豆油,产仔数增加了2.85%,弱仔数降低了7.69%,仔猪断奶体重提高了2.19%,断奶活仔猪数增加2.10%。复合脂肪中的高卵磷脂和必需脂肪酸可以改进母猪生产性能和仔猪健康。
