摘要
先后用21头大约克×沙乌头和27头大约克×梅山猪作了两次在日粮中添加沼液的试验。试验Ⅱ因雨水冲淡了沼液而收效不明显。在试验Ⅰ中,添加15—30%沼液组和添加20%—40%沼液组的平均日增重分别比对照组高出10.99%和13.26%;每kg增重消耗饲料量分别比对照组减少7.36%和10.34%;经济收益分别比对照组多17.22元和23.66元。试验猪贪睡少动、皮肤红润、被毛光亮。试验证明,沼液是一种优良添加剂,用来喂猪,不仅提高了养猪的经济效益,而且促进了生态系统内的物质循环。
Twenty-one Yorkshire×Shawutou and Twenty-seven Yorkshire×Meishan pigs were use to test the ration with methane fluid added for twice. Test Ⅱ had no apparent effects because of methane fluid diluted by rainfall water, In test Ⅰ, the average daily gain in weight in pigs in group with 15%—30% of methane fluid added to ration and in the group with 20%—40% of methane fluid in ration is 10.99% and 13.26% higher than in the control. Grain feed consumed by per kg gain in weight is reduced by 7.36% and 10.34% as against that in the control; and economic income is 17.22 Yuan and 23.66 Yuan more than that in the control. The testing pigs like to sleep with less movement, red in skin and bright in hair. The tests have proved that methane is a kind of fine additive, which can not only raise economic benefits of pig raising but also promote the material cycles of ecological system.
