“…Non-treated SBM that was heated at 100 C had greater (P<.05) residual N at 4, 8, 12 and 24 h than non-heated, nontreated SBM. This agrees with the results of Plegge et al (1982), who found that roasting SBM at 128 C or above, increased (P<.05) in situ residual N. Soybean meal dried at 100 C following soaking in H20, .5 N propionic acid or .5 N HC1 had greater (P<.05) residual N values at 4, 8, 12 and 24 h and slower (P<.05) rates of N disappearance than non-treated SBM or non-treated SBM heated at 100 C. Soybean meal soaked in .5 N NaOH and dried at 100 C had greater (P<.05) residual N than non-treated SBM at 12 and 24 h of incubation.…”

“…Research on chemical methods has concentrated on treatment with formaldehyde (Spears et al, 1980), tannins (Hartnell and Satter, 1978;Thomas et al, 1979) or alcohols (van der Aar et al, 1982). The most extensively investigated physical treatment has been the application of heat (Broderick and Craig, 1980;Plegge et al, 1982). Treatment of SBM with heat, formalt Salaries and research support provided by State and Federal Funds appropriated to the Ohio Agr.…”

Soybean meal (SBM) was treated with acid or alkali to determine effects on N solubility, in vitro NH3-N accumulation, in situ N degradability, and N digestion and retention in growing lambs. The following SBM treatments resulted in decreased (P less than .05) N solubility and in vitro NH3-N accumulation compared with control SBM: spraying with 2.5 or 5% acetic or propionic acid, soaking in .5 N HCl, .5 N NaOH or .5 N propionic acid followed by air drying, and soaking in H2O, .5 N HCl or .5 N propionic acid followed by drying at 100 C. In situ residual N was determined for SBM subjected to the above treatments. Soybean meal sprayed with 2.5 or 5% acetic or propionic acid had greater (P less than .05) in situ residual N after 4, 8 and 12 h of incubation than control SBM. Soybean meal soaked in .5 N HCl or .5 N NaOH and air-dried, and soaked in H2O, .5 N propionic acid or .5 N HCl and dried at 100 C had greater (P less than .05) in situ residual N after 4, 8, 12 and 24 h of incubation than control SBM. In a lamb N balance trial, SBM treated by spraying with 5% acetic or propionic acid or by soaking in .5 N NaOH did not result in reduced N digestion compared to control SBM. Feeding SBM soaked in .5 N NaOH resulted in a 39% increase (P less than .05) in N retention compared with control SBM (5.21 vs 3.74 g/d, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

“…This did not occur with the treatments used either in the present calf study or in our earlier rat growth trial (Mir et al 1984). Decreased DM and N digestibilities have been observed where calves were fed soybean meal treated with heat (Plegge et al 1982) or formaldehyde (Crooker et al 1983). Also of concern is thepossibility that treatments may rsult in lowered digestibility of the non-nitrogen fractions.…”

“…Utilization of supplemental proteins can be improved by chemical (Nishimuta et al, 1973(Nishimuta et al, , 1974 or heat treatment (Plegge et al, 1982). Formaldehyde has been the most common chemical used, but it has the important disadvantage of being hard to work with and is not allowed in some countries as a means of protecting protein from microbial degradation in the rumen.…”

Six mature Holstein cows in late lactation and fitted with permanent ruminal, duodenal and ideal cannulae were used in a double 3 X 3 Latin-square design to study the effect of roasting or extruding of cottonseed on protein degradation in the rumen and availability of amino acids in the small intestine. Raw whole cottonseed (CS), extruded whole cottonseed (ECS), and roasted whole cottonseed (RCS) were fed in diets containing 17% crude protein and composed of 42% whole cottonseed, 26% corn grain and 29% hay supplemented with dry molasses, vitamins and minerals. The diets were isocaloric and contained 1.86 Mcal NEL/kg. Acid detergent lignin was used as a digesta marker, and diaminopimelic acid as a bacterial marker. Ruminal ammonia concentration was higher (P less than .05) for CS than for ECS and RCS (15.7, 12.7 and 10.2 mM). Concentrations of isobutyrate (1.3 vs 0.8 and 0.8 mM) and isovalerate (1.8 vs 1.1 and 1.1 mM) were higher (P less than .05) for CS compared with ECS and RCS. Non-ammonia nitrogen flow to the duodenum (g/d) was 248, 300 and 350 for CS, ECS, and RCS, with RCS higher (P less than .05) that in CS. Apparent absorption of total amino acids in the small intestine was .80, 1.01, and 1.24 kg/d, for CS, ECS, and RCS, respectively, with RCS higher (P less than .05) than CS. Apparent absorption of essential and non-essential amino acids was 376, 425; 458, 548;610 and 628 g/d for CS, ECS and RCS respectively, with RCS higher (P less than .05) than CS.
