This study aimed to evaluate the effect of different amounts of incubated samples on the kinetic parameters of in vitro fermentation of roughage and concentrated food used for feeding ruminants. Samples were prepared using 200, 300, 400, and 500 mg of air-dried roughage and concentrated sample, ground to 1 mm, and placed in 120 mL glass flasks. Next, inoculum and McDougal solution were added, and the readings were obtained using a semi-automated pressure transducer up to 96 h after the beginning of the incubations. Gas production of the non-fibrous fraction increased linearly (P < 0.05) for sugarcane, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, bean residue, wet brewer’s grains, sunflower meal, and Jatropha meal; quadratically (P < 0.05) for Napier grass silage and cottonseed meal; and cubically (P < 0.05) for castor meal and soybean meal. The degradation rate of the non-fibrous fraction reduced linearly (P < 0.05) for sugarcane, Napier grass silage, and castor meal; quadratically (P < 0.05) for Marandu grass silage; and cubically (P < 0.05) for corn silage, soybean meal, dried corn distillers’ grains with solubles, bean residue, and cottonseed meal. Gas production of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, Marandu grass silage, corn silage, dried corn distillers’ grains with solubles, bean residue, wet brewer’s grain, cottonseed meal, and sunflower meal; quadratically ( < 0.05) for Jatropha meal; and cubically (P < 0.05) for sugarcane, castor meal, and soybean meal. The degradation rate of the fibrous fraction increased linearly (P < 0.05) for Napier grass silage, dried corn distillers’ grains with solubles, dried brewer’s yeast, wet brewer’s grains; quadratically (P < 0.05) for corn silage and castor meal; and cubically (P < 0.05) for sugarcane, Marandu grass silage, and bean residue. The lag time reduced linearly (P < 0.05) for castor meal and dried corn distillers’ grains with solubles; quadratically (P < 0.05) for Napier grass silage; and cubically (P < 0.05) for sugarcane, Marandu grass silage, corn silage, soybean meal, bean residue, cottonseed meal, sunflower meal, and Jatropha meal. Thus, our findings suggest that the kinetic parameters of in vitro fermentation were affected as a function of the amount of incubated sample.

ABSTRACT Feeding corn wet distillers grains with solubles (WDGS) to cattle can increase the load of Escherichia coli O157:H7 in feces and on hides, but the mechanisms are not fully understood. The objective of these experiments was to examine a role for the persistence of E. coli O157:H7 in the feces and feedlot pen surfaces of cattle fed WDGS. In the first study, feces from steers fed 0, 20, 40, or 60% corn WDGS were inoculated with E. coli O157:H7. The E. coli O157:H7 numbers in feces from cattle fed 0% corn WDGS rapidly decreased (P &lt; 0.05), from 6.28 to 2.48 log CFU/g of feces by day 14. In contrast, the E. coli O157:H7 numbers in feces from cattle fed 20, 40, and 60% corn WDGS were 4.21, 5.59, and 6.13 log CFU/g of feces, respectively, on day 14. A second study evaluated the survival of E. coli O157:H7 in feces from cattle fed 0 and 40% corn WDGS. Feces were collected before and 28 days after the dietary corn was switched from high-moisture corn to dry-rolled corn. Within dietary corn source, the pathogen persisted at higher concentrations (P &lt; 0.05) in 40% corn WDGS feces at day 7 than in 0% WDGS. For 40% corn WDGS feces, E. coli O157:H7 persisted at higher concentrations (P &lt; 0.05) at day 7 in feces from cattle fed high-moisture corn (5.36 log CFU/g) than from those fed dry-rolled corn (4.27 log CFU/g). The percentage of WDGS had no effect on the E. coli O157:H7 counts in feces from cattle fed steam-flaked corn-based diets containing 0, 15, and 30% sorghum WDGS. Greater persistence of E. coli O157:H7 on the pen surfaces of animals fed corn WDGS was not demonstrated, although these pens had a higher prevalence of the pathogen in the feedlot surface manure after the cattle were removed. Both or either the greater persistence and higher numbers of E. coli O157:H7 in the environment of cattle fed WDGS may play a part in the increased prevalence of E. coli O157:H7 in cattle by increasing the transmission risk.
