在4周的实验中,初始体重9.8公斤的保育猪,饲喂以下6种饲料:

 

  1. 正对照,使用干净的玉米(全价料呕吐毒素含量0.38ppm)

  2. 负对照,使用呕吐毒素5.5ppm的玉米(全价料呕吐毒素含量2.3ppm)

  3. 负对照加酶+吸附剂1(全价料呕吐毒素含量2.3ppm)

  4. 负对照加黏土(全价料呕吐毒素含量2.3ppm)

  5. 负对照加酶+吸附剂2(全价料呕吐毒素含量2.4ppm)

  6. 负对照加焦亚硫酸钠(全价料呕吐毒素含量1.9ppm)

 

实验结果

 

第一周,焦亚硫酸钠组比负对照组和黏土组生长速度更快(P=0.01),其他各组生长速度居中,与负对照组和黏土组没有显著差异。焦亚硫酸钠组比其他各组料肉比更好(P=0.02)。

 

其他阶段,各组生长性能在统计上都没有显著差异。各组采食量没有显著差异。

 

试验结束时各组平均体重(公斤)分别为:31.3(正对照),  30.8(负对照),  30.4(酶+吸附剂1),  30.8(黏土), 31.1(酶+吸附剂2), 32.2(焦亚硫酸钠)。

 

总结

 

正对照和负对照生产性能没有显著差异,显示保育猪对呕吐毒素的忍耐度高于规定的1ppm上限。

 

以下为英文摘要部分内容:

 

Four commercial feed additives (CFA) wereevaluated for efficacy in detoxifying deoxynivalenol (DON) in diets fed to 144nursery pigs (BW 9.80+/- 0.5kg; 2 gilts, and 2 barrows/pen). Six testcorn-soybean-meal based diets were:  1)positive control (PC),  formulated withclean corn,  (NC), 2) formulated withcontaminated corn (5.5 ppm DON),  3) NCwith enzyme+binder1 (NCB1),  4) NC withclay (NCC),  5) NC with enzyme+binder2(NCB2) and  6) NC with sodiummetabisulfite (NCP).  Diets wereallocated to pens (n = 6) based on BW and fed ad-libitum for 4-wk.
Assayed DON concentration for PC, NC, NCB1,NCC, NCB2 and NCP were 0.38, 2.3, 2.3, 2.3, 2.4, and 1.9 ppm, respectively.
Diet effects were only observed for ADG andG:F in wk-1; pigs fed NCP had higher (P = 0.01) ADG compared topigs fed NC and NCC, whilst pigs fed other diets had intermediate and similarADG (P > 0.05) to pigs fed NC or NCC. Pigs fed NCP showed higher(P = 0.02) G:F relative to pigs fed other diets. The final BW was31.3, 30.8, 30.4, 30.8, 31.1 and 32.2kg for PC, NC, NCB1, NCC, NCB2 and NCP-fedpigs, respectively. There were no (P > 0.05) diet effects onADFI throughout the study.
In conclusion, the lack of differencesbetween PC and NC suggested pigs were tolerant to higher DON levels than theregulated dietary maximum of 1 ppm.

 

 

  1. 本次试验虽然正对照和负对照在统计上没有差异,但从数值上看,负对照比正对照还是差一些。酶+吸附剂1和黏土对呕吐毒素没有效果。

  2. 在四周的保育试验中,没有看到显著差异,但随着时间延长,呕吐毒素在体内的累积,高呕吐毒素饲料的影响也许会逐渐显现。

  3.  本次试验数据显示,饲料添加焦亚硫酸钠,对保育猪生长性能有益。其他试验也发现,在高温制粒的条件下,焦亚硫酸钠可以结合呕吐毒素,促进保育猪生长。
