The effect of depths and of addition of inoculums on the chemical content of swine beddings was evaluated. For beddings 0.25m (25D) and 0.50m (50D) deep, three treatments were tested in two repeats with the same beddings: control (no inoculums); T1 (250g of Bacillus cereus var. toyoii at 8.4×10(7)CFU/g); and T2 (250g of a pool of Bacillus sp. at 8.4×10(7)CFU/g) (250g for 25D and 500g for 50D). For 25D, the C:N ratio was lower, but N, K and C contents were greater than for 50D (P<0.05). The inoculums did not benefit any chemical parameter (P>0.05). In the second repeat, beddings presented lower C:N ratio and greater N, P and K contents than in the first repeat (P<0.05). Thus, the compost produced after using 25D twice had greater fertilizer value than that of 50D.
评估了深度和接种物添加对猪垫料化学含量的影响。对于 0.25m（25D）和 0.50m（50D）深的垫料，在两次重复中用相同的垫料测试了三种处理方法：对照（无接种物）；T1（250g 解淀粉芽孢杆菌 var. toyoii，浓度为 8.4×10(7)CFU/g）；和 T2（250g 混合芽孢杆菌，浓度为 8.4×10(7)CFU/g）（25D 用 250g，50D 用 500g）。对于 25D，C:N 比更低，但 N、K 和 C 含量高于 50D（P<0.05）。接种物对任何化学参数都没有益处（P>0.05）。在第二次重复中，垫料的 C:N 比和 N、P 和 K 含量均低于第一次重复（P<0.05）。因此，两次使用 25D 后产生的堆肥比 50D 的肥料价值更高。
