AB  - The objective of this experiment was to determine the fermentation 
  quality of wet Potato Pulp (PP) treated with different absorbents. The absorbents 
  were three agricultural by-products, dry Rice Straw (RS), dry Corn Stovers (CS) 
  and dry Bean straw with Pods (BP). Four different ingredient combinations were 
  investigated: 100% PP (Control), 80% PP+20% RS (RSP), 80% PP+20% CS (CSP) and 
  80% PP+20% BP (BPP). The laboratory bags were kept in the room, then were opened 
  on 0, 3, 7, 10 and 50 days after ensiling for fermentation quality and chemical 
  analysis, respectively. There was 110.52 mL kg<SUP>-1</SUP> silage effluent 
  production in the control while the absorbent treatments had no effluent losses. 
  The Dry Matter (DM) loss was higher in the control (21.22% DM) than all the 
  absorbent treatments (RSP, CSP and BPP) and the differences were significant 
  (p&lt;0.05). For all silages, there was a fast and large reduction in pH from 
  the 3rd day of ensiling to &lt;4.2. After ensiling, the pH value in all silages 
  attained &lt;4.00. The absorbents inhibited the break down of silage protein 
  and the ammonia nitrogen (NH<SUB>3</SUB>-N) content of absorbents addition silage 
  significantly (p&lt;0.05) lower than the control after 50 days of ensiling. 
  Compared with the control, only the treatment RSP resulted in higher (p&lt;0.05) 
  lactic acid concentration. The acetic acid content in the absorbent treatments 
  were (p&lt;0.05) lower than that of the control silage. All the absorbent silages 
  had a higher quality Fleig point than the control silage (p&lt;0.05). These 
  results indicated that adding the absorbent to potato pulp silage could prevent 
  the effluent losses and reduced the silage DM loss during the ensiling and improved 
  the fermentation quality.
