摘要
麦饭石饲喂生长肥育猪,可以明显地提高肥猪的增重,降低饲料消耗,增加收入。在不同体重阶段,日喂量为35g,25g,15g等3个不同剂量条件下。各试验组日增重均高出对照组,其中小猪各试验组平均比对照组高出2.48%～17.78%,中猪各试验组平均比对照组高出6.01%～17.09%;其料肉比,小猪各试验组比对照组降低4.49%～8.99%,中猪各试验组比对照组降低o.82%～2.45叻;其纯增收入,小猪各试验组分别比对照组高24.21%,13.28%和5.13%,中猪各试验组分别比对照组高14.15%,22.26%和6.03%。其最佳饲喂量,小猪为35g,中大猪为25g。
Using the Hunan medical stone to feed growing-fattening pigs canobviously increase gain and return, and decrease feed consumption. With differ-ent body-weight stage (weaner and fattening pigs) and different dose of Hunanmedical stone (35, 25and 15g/day), the daily gains of all the treatment groupswere higher than the control groups, by 2.48%~17.78% higher with weaner pigs,and 6.01%~17.09% higher with fattening pigs. The feed consumption of the trea-tment groups were lower than that of the control group 4.49%~8.99%, with we-aner pigs and 0.82%~2.45% with fattening pigs. Feeding pigs with medical stonecan increase return significantly, three treatment groups were higher than controlgroup by 24.21%, 13.28% and 5.13% respectively with weaner pigs, and by14.15%, 22.26% and 6.03% respectively with fattening pigs, the results indicatedthat the optimum dose of medical stone is 35g/day for weaner pigs and 25g/dayfor fattening pigs.
