HighlightsRespiration rate increased with the percentage of split soy beans.The splits multiplier for soybeans appears to be more sensitive than the corn damage multiplier.The relationship between the split percentage and splits multiplier for soybeans is approximately linear.A value for the splits multiplier is provided for 18% moisture content soybeans stored at 35°C.Abstract. The objectives of this study were to compare the effects of 0% to 16% (w/w) splits content (xs) of soybeans stored at 35°C and 18% moisture content (w.b.) on dry matter loss rates (vDML) and to determine a splits multiplier (MS) for soybeans stored at these conditions, similar to the damage multiplier (MD) used in ASABE Standard D535 for shelled corn. Effects of percentage by weight splits (xs) on MS and safe storage time are expected to be greater than MD for corn because soybeans are prone to cracking and splitting, lipid oxidation, and protein degradation, all of which lead to grain dry matter and quality losses. Results indicated that vDML increased with increasing xs, and the mean vDML was 1.5 times greater for samples with 16% splits than for samples with 4% splits. The MS for soybeans was linearly correlated with xs, decreasing from 1.0 to 0.60 for 0% to 16% splits, respectively. Soybeans appeared to be more sensitive to percent by weight splits than corn was to the presence of damaged kernels. In Standard D535, the MD for corn only decreased from 1.0 to 0.8 when percent (w/w) damaged kernel content increased from 30% to 40%. In comparison, it should be noted that damage to soybeans was defined differently from damage to corn. This research is useful in defining MS for 18% moisture content soybeans stored at 35°C under hermetic conditions. The procedures outlined in this article may be used in the future to more formally define a soybean MS that covers a wider range of moisture contents, storage conditions, and possibly an MD based on other factors included in the USDA definitions of damaged soybean kernels. Keywords: Allowable storage time, Grain quality, Splits multiplier.

HighlightsDesign, description, and comparison of static (S) and dynamic (D) grain respiration measurement systems (GRMS).No differences were detected between dry matter loss rates (vDML) from S-GRMS and D-GRMS for soybeans at 18% moisture content and 30°C stored for 20 d.Literature reports variable vDML estimates for soybeans stored in S-GRMS and D-GRMS; more studies should be conducted with a wider range of storage conditions before developing maximum allowable safe storage time guidelines.Abstract. Time to reach 0.5% dry matter loss (DML) is the estimated maximum allowable storage time (MAST) for shelled corn and has been suggested for use with other grains. Respiration studies have reported various estimates of this threshold depending on the type of grain respiration measurement system (GRMS) and storage conditions tested. The objectives of this study were (1) to design and evaluate two GRMS in which oxygen needed for respiration was limited in a static system (S-GRMS) or continuously supplied in a dynamic system (D-GRMS) during storage and (2) to compare the effects of GRMS on DML rates (vDML) for 18% moisture content soybeans stored at 30°C for 20 d. In this study, S-GRMS and D-GRMS units were designed to conduct respiration tests. Respired CO2 (mg CO2) was measured over time and used to calculate the specific mass of respired CO2 (mg CO2 kg-1 d.b. beans) and subsequent DML (%) using stoichiometric ratios from the respiration chemical reaction. DML rates, vDML (% d-1), were estimated by least squares linear regression of DML and time data. Four replications of respiration tests were conducted in each GRMS. Average estimates of vDML were 0.0157% d-1 and 0.0189% d-1 for S-GRMS and D-GRMS, respectively. Mean vDML from D-GRMS tests was 1.2 times greater than mean vDML from S-GRMS but not statistically different (p = 0.09). However, the coefficient of variation was 8 times greater for D-GRMS than for S-GRMS. More studies with a wider range of storage conditions should be conducted for development of a safety factor between both systems prior to using data from respiration of soybeans in the literature to estimate MAST.

Carbon dioxide evolution was used to determine the storage life of 22.7% moisture shelled corn. Four iprodione fungicide treatments plus an untreated control were tested. The fungicide was tested on corn having three levels of mechanical kernel damage: 7% (hand shelled), 25% (combine harvested), and 16% (a blend of the other two damage levels). All iprodione treatments significantly increased storage life. Corn samples with higher levels of kernel damage took shorter times to reach the 0.5% dry-matter loss (DML) level. For combine-shelled corn, the fungicide increased storage life 17% at 15 mg/kg of corn and 46% at 20 mg/kg of corn.

Two new isosynthetic strains of birdsfoot trefoil (Lotus corniculatus L.), containing low or high concentrations of tannin, were tested using in vitro and in sacco digestibility techniques. The high tannin (HT) strain contained an average of five times more tannin on a dry matter basis, than the low tannin (LT) strain. After 24-h in vitro digestion, by a rumen inoculum, there was less (P < 0.01) dry matter disappearance (45.7 vs. 54.4%) from the HT strain. Also, the development of gas pressure was lower (P < 0.01) and production of volatile fatty acids less (P < 0.05) with the HT strain than with the LT strain. Average dry matter loss from four replicated nylon bags was also lower (P < 0.01) for the HT strain than for the LT strain after 8, 12, and 24 h of incubation in rumen. These data indicate that a LT strain of birdsfoot trefoil might improve the forage digestibility. Key words: Birdsfoot trefoil, tannin, digestibility
