Six experiments were conducted to investigate the effect of a feed supplement on the performance of grazing Belgian Blue double-muscled (BBDM) heifers with an initial weight and age of 195 ± 43 kg and 190 ± 52 days. Treatments included were: Exp. 1: supplementation with beet pulp (BP): 2 kg/day per head v. ad libitum intake; Exp. 2: supplementation ad libitum with BP v. a mixture of BP and soyb...

Lynch, G.L., Berger, L.L., Fahey, G.C., Jr. and Baker, E.C., 1986. Effects of isopropyl alcohol treatment of soya bean meal on nitrogen utilization by ruminants. Anim. Feed Sci. Technol., 14: 127-137. Soya bean meal (SBM) treated with isopropyl alcohol (IPA) or n-propyl alcohol (NPA) was used to study effects of alcohol treatments on SBM nitrogen (N) utilizatinn by ruminants. The IPA treatments...

Six mature wethers (BW 72 kg) with ruminal, duodenal, and ileal cannulas were fed a basal (no added soybean meal [SBM]) diet or diets containing unheated SBM or SBM roasted at 165 degrees C for 75, 150, 180 or 210 min in a 6 x 6 Latin square experiment. Concentrations of indicators of heat exposure (NDF, ADF, and ADIN) in SBM increased with increasing roasting time. Organic matter digestion cha...

Two experiments were conducted to determine U.S. soybean meal (SBM) variation. In experiment 1, SBM from 55 U.S. processors was evaluated. Significant (P < 0.05) but numerically small differences were detected in dry matter (DM) and organic matter (OM) concentrations. Crude protein (CP) concentrations (51.6-54.6%) were higher (P < 0.05) in SBM produced in the southern U.S. Lipid and total dieta...

The objective of this study was to determine the effects of source of dietary CP and level of ruminally protected lysine and methionine (RPLM) on feedlot performance and carcass characteristics of Holstein steers during a growing-finishing trial (266 d). A total of 168 Holstein steers (182.7 +/- 27.5 kg) were used in a completely randomized design experiment (eight treatments; three pens of sev...

Three experiments were conducted to determine the feeding value to broiler chicks of soybean meal (SBM) produced from high-protein (SBM-HP), low-oligosaccharide (SBM-LO), or conventional (SBM-CV) varieties of soybeans. The 3 SBM contained 54.9, 53.6, and 47.5% CP, respectively. The standardized digestibility (SDD) of amino acids (AA) in the 3 ingredients was measured using a precision-fed roost...

Six mature wethers (BW 72 kg) with ruminal, duodenal, and ileal cannulas were fed a control (no added soybean meal [SBM]) diet or diets containing unheated SBM or SBM roasted at 165 degrees C for 75, 150, 180, or 210 min in a 6 x 6 Latin square experiment. Concentrations of indicators of heat exposure (ADIN, ADF, NDF) in SBM increased with increasing roasting time. Duodenal flows of total N, no...

Two experiments were conducted to determine AA digestibility and the concentration of DE and ME in 5 sources of soybean meal (SBM). The 5 sources included hexane-extracted SBM produced from high-protein soybeans (SBM-HP) and conventional soybeans (SBM-CONV), and mechanically extruded-expelled SBM produced from high-protein soybeans (EE-SBM-HP), low-oligosaccharide soybeans (EE-SBM-LO), and conv...

The SBM mouse is a unique transgenic model of polycystic kidney disease (PKD) induced by the dysregulated expression of c-myc in renal tissue. In situ hybridization analysis demonstrated intense signal for the c-myc transgene overlying tubular cystic epithelium in SBM mice. Renal proliferation index in SBM kidneys was 10-fold increased over nontransgenic controls correlating with the presence o...

Three experiments were conducted to evaluate lysine (Lys), threonine (Thr), methionine (Met), tryptophan (Trp), and nonessential N (+N) supplementation of all sorghum grain (S) diets on growth and carcass characteristics of 50- to 100-kg pigs. In Exp. 1, four replicate pens of four pigs each were fed: 1) sorghum-soybean meal positive control (S-SBM); 2) S + Lys + Thr + Met + Trp to equal the am...
