Efficacy of sulfur dioxide as a grain preservative

The Performance of Dairy and Feedlot Cattle Fed Sulfur Dioxide-Treated High-Moisture Barley

“…Additionally, there was a 100-fold increase in the fungi population over that measured for preserved SO2-treated HMB fed at the same time (Gibson et al 1988). No fungi were identified for spoiled grain fed in this trial, nor were there screening tests performed for mycotoxins.…”

“…The efficacy of sulfur dioxide (SO) as a grain preservative has recently been evaluated (Mathison et al 1985;Gibson et al 1988). Mathison et al (1985) (Gray 1980 (Merck 1979 (Harwig and Munro 1975 (Dufour et al 1954), milk production and body weight change (Knodt et al 1952;Dufour et al 1954) when not confounded by excessive (Stallcup 1955) or uneven SO2 application (Bratzler et al 1956).…”

“…The influence (P>0.05) of NaHCO3 addition to the SO2-treated diet on increasing carcass fat depth without effecting ADG or DM:gain was also reported by Mathison et al (1985). (Gibson et al 1988), (2) SO2 is corrosive to most metals (Mathison et al 1985), (3) fumes from SO2 are more obnoxious than those of propionic acid, and (4) the potential interference of SO2-derived S with the metabolism of the animal.…”

Ammonia or Sulphur Dioxide Treatment of High-Moisture Barley on in Situ Rumen Degradability and in Situ Whole-Tract Digestibility

“…Thus. benefits of sulphur dioxide treatment of highmoisture barley appear limited to its demonstrated role as a grain preservative (Gibson et al 1988b Thus, it appears that starch, which comprises (Perdok and Leng 1987) and so another mechanism of action must be responsible.…”

Efficacy of Anhydrous Ammonia and Sulfur Dioxide as Preservatives for High-Moisture Grain and Their Effect on the Nutritive Value of Barley for Growing-Finishing Cattle

“…There is evidencethat molds may also reduce the thiamin content of grain (Loew et al 1972;citedby Blood et al (1983)) so a thiamin deficiency in the control group of cattle might have been expected. Similarly, it has been shown that sulfur dioxide treatment destroys thiamin in the grain, and in previous studies sulfur dioxide-treated grain resulted in thiamin deficiencies in cattle (Gibson et al 1988a;Mathison etal. 1988).…”
