Three experiments were conducted to evaluate paddy rice as an alternative energy feedstuff in low-protein diets for pigs. In Experiment 1, a total of 400 growing pigs (20.68 ± 0.29 kg initial bodyweight), were randomly allocated four dietary treatments with 0, 10, 15, and 20% paddy rice for 30 days. Feeding 10% or 15% paddy rice had no adverse impacts on average daily gain (ADG) and feed to gain ratio (F:G), while the inclusion of 20% rice in diets significantly influenced the growth performance of pigs. In Experiment 2, 364 early-finishing pigs (42.25 ± 0.47 kg) were divided into four treatments with 0, 15, 20, and 25% paddy rice for 35 days. Feeding 15% or 20% paddy rice had no negative consequences on growth performance, while pigs fed with 25% rice had the lowest ADG and the greatest F:G. In Experiment 3, 364 late-finishing pigs (79.52 ± 1.28 kg) were divided into four treatments with 0, 20, 25, and 30% paddy rice for 60 days. Paddy rice can be included at up to 30% in diets without compromising growth performance, while feeding with 25% rice significantly improved the performance for pigs compared with the corn-fed control.
进行了三项试验以评估水稻作为猪低蛋白日粮中替代能量饲料原料的效果。在试验1中，总共400头生长猪（初始体重20.68±0.29千克）被随机分配到四种日粮处理组，日粮中水稻含量分别为0%、10%、15%和20%，试验期30天。饲喂10%或15%水稻对平均日增重（ADG）和料重比（F:G）没有不利影响，而日粮中添加20%水稻显著影响了猪的生长性能。在试验2中，364头育成前期猪（42.25±0.47千克）被分为四种处理组，日粮中水稻含量分别为0%、15%、20%和25%，试验期35天。饲喂15%或20%水稻对生长性能没有负面影响，而饲喂25%水稻的猪平均日增重最低，料重比最高。在试验3中，364头育成后期猪（79.52±1.28千克）被分为四种处理组，日粮中水稻含量分别为0%、20%、25%和30%，试验期60天。日粮中水稻含量最高可达30%而不影响生长性能，与玉米对照组相比，饲喂25%水稻显著提高了猪的生长性能。
