摘要/Abstract

摘要： [目的]比较研究两种阶段肥育法对生长肥育猪粪氮和粪磷排放量的影响。[方法]选用平均体重19.5±1.6 kg的杜长大三元杂交生长猪72头，随机分为2个组，每组6个重复，每个重复6头猪，对照组采用“三阶段”育肥法，三阶段划分为：20~50、50~80、80~120 kg，试验组采用“五阶段”育肥法，五阶段划分为：20~35、35~55、55~75、75~95、95~120 kg。[结果]结果表明，两种阶段育肥法饲粮氮、磷表观消化率相近；与“三阶段”育肥法相比，“五阶段”育肥法生长肥育猪全期饲粮氮总摄入量减少5.17%（P<0.05），饲粮磷总摄入量减少8.79%（P<0.05），粪氮排放量减少6.10%（P<0.05），粪磷排放量减少8.64%（P<0.05）。[结论]采用“五阶段”育肥法，能显著降低生长肥育猪饲粮氮、磷摄入量和粪氮、磷排放量，具有良好的生态环境效益。

Abstract: [Objective]The N and P in the excretion of pigs at final growth stage fed under two different feeding programs were compared for forage utilization and ecological effect on the environment.[Method]A total of 72 growing Duroc×Landrace×Yorkshire pigs weighing 19.5±1.6 kg were randomly divided into two groups with 6 replicates of 6 pigs each. The groups were fed under two different programs:a 3-phase-feeding at 20-50 kg, 50-80 kg, and 80-120 kg pig weight stages or a 5-phase-feeding at 20-35 kg, 35-55 kg, 55-75 kg, 75-95 kg, and 95-120 kg pig weight stages. The fecal N and P of the pigs were determined for the analysis.[Result] The variation on feeding program did not cause significant difference on the apparent N and P digestibility of the pigs. On the other hand, comparing to the 3-phase-feeding, the pigs under the 5-phase-feeding program showed significant reductions of 5.17% on total dietary N intake (P<0.05) and of 8.79% on P (P<0.05), as well as of 6.10% on fecal N (P<0.05) and of 8.64% on fecal P (P<0.05).[Conclusion]Feeding the pigs at final growth stage on the 5-phase program reduced the forage consumption and also the N and P in excretion of the animals resulting in financial as well as ecological benefits.
