摘　　要：旨在探讨饲喂液体饲料对断奶仔猪生长性能及养殖效益的影响。将3 180只断奶仔猪随机分为试验组（n=1690）和对照组（n=1490）。试验组仔猪断乳后不同时间饲喂不同配比的液态饲料,对照组按常规方法饲喂仔猪专用颗粒料。观察、记录并比较试验组和对照组仔猪断奶后不同时间的日平均采食量、周平均净增重、试验期间的耗料量、料肉比、成活率,并比较2组的养殖效益。结果表明,断奶第1周至第5周,试验组仔猪的日平均采食量比对照组提高10.45%~20.05%,试验组仔猪的周平均净增重比对照组提高7.75%~13.61%;试验组仔猪的成活率较对照组提高0.81%,料肉比较对照组降低0.10;试验组仔猪的每千克增重成本较对照组降低0.57元（6.74%）。综上提示,饲喂液态饲料能够减少断奶仔猪的应激反应、增加采食量、提高生长速度和成活率、降低养殖成本,具有一定的推广应用潜力。This study aimed to evaluate the feeding effect of liquid feed on growth performance and rearing benefit of weaned piglets. A total of 3 180 weaned piglets were randomly assigned to one of the two groups： the experimental group（n=1690） fed different proportion of liquid feed in different experimental stages, and the control group（n =1490） fed pellet diet specific for piglets in normal ways during the whole experimental period. The daily average feed intake, weekly average net gain, feed consumption during the experimental period, feed conversion ratio and survival rate of the experimental group and control group in different experimental stages were observed, recorded and statistically compared. Meanwhile, the rearing benefit of the two groups was also evaluated. The results showed that during the 1stweek to 5thweek, the daily average feed intake of experimental group was increased by 10.45%-20.05% compared with that of control group, and the weekly average net gain was increased by 7.75%-13.61% compared with that of control group; the survival rate of the piglets in experimental group was increased by 0.81%compared with that in control group, and the feed conversion ratio was 0.10 lower than that of control group; the weight gain cost per kilogram in experimental group was 0.57 Yuan（6.74%） lower than that of control group. The combine data reveal that feeding liquid feed is able to relive the stress response, increase the feed intake, improve the growth performance and survival rate, and reduce the rearing benefit, which is worthy of promotion and application.
