The Relationship

High moisture (HM) shelled corn (66.7% dry matter), preserved with 1.5% propionic acid, was fed as a part of the ration to 12 lactating dairy cows, seven growing dairy heifers, and 20 growing-finishing pigs. HM ensiled, shelled corn was fed to similar groups as a comparison. In addition, a third group of 12 cows received a commercial dairy supplement. Fat-corrected milk yield, persistency of milk production, milk fat and protein percentage, and rate of gain by dairy heifers were not significantly different between rations when HM corn was fed at 4.5 kg/animal/day. Average daily gains by pigs whose ration comprised 70% treated grain corn versus 70% ensiled grain corn were 0.70 and 0.63 kg (P < 0.01). A nonsignificant improvement in feed efficiency was observed by heifers and pigs fed treated grain corn. Mold counts were 0 and 1200 colonies/g for treated and ensiled grain corn. There was no adverse effect of propionic acid treatment upon animal health or performance. The relationship between dietary propionic acid and synthesis of milk fat, milk protein and tissue protein are discussed.

Wet Weight

Two trials with growing-finishing steers and one trial with lactating dairy cows were conducted to evaluate the feeding value of high moisture (HM) corn preserved with 1.5% propionic acid on a wet weight basis. Combining all treatments, acid-treated HM corn was 9% more efficient (P < 0.05) for weight gains than dry corn. Ensiled HM corn also tended to be utilized more efficiently by steers than dry corn when no fat was included in the ration. However, in the second steer trial, acid-treated reconstituted HM corn was comparable in performance with dry corn. Addition of 4% tallow tended to improve feed efficiency by 5–6% with dry or acid-treated HM corn, but to decrease feed efficiency with ensiled HM corn. No significant differences were observed in forage dry matter intake, milk production, or milk composition with cows fed treated HM corn compared with dry corn. However, a trend for a slight reduction in milk fat percent occurred with the treated corn ration.

Feeding Value

Three experiments were conducted (1) to compare the feeding value of dried shelled corn and acid-treated high moisture (HM) corn and (2) to determine the effects of rolling acid-treated HM corn for all-concentrate diets fed to finishing beef-type cattle and to growing and finishing Holstein male calves. In a 120-day finishing period, Hereford and Hereford × Charolais steers performed similarly with respect to gain, feed efficiency, carcass measurements and grade on whole dried corn and on whole and rolled acid-treated HM corn. No health problems occurred during the feeding trial in which gains averaged 1.49 kg per day. The performance of Holstein male calves fed from a starting weight of 95 kg to 385 kg also demonstrated that acid-treated HM corn was comparable in feeding value to dried shelled corn. While growth of calves on whole and rolled HM corn was similar (1.24 kg/day), four calves receiving rolled HM corn were lost from the experiment due to acute bloat, laminitis and peritonitis. One calf fed whole dried corn had peritonitis and was also removed from the experiment. Incidence of liver abscesses among cattle completing the trials was 28 and 26% for beef-type and Holstein cattle, respectively. Rumen abnormalities, i.e. clumping of papillae, ulceration of rumen epithelium and accumulation of hair, were evident in calves on all treatments. Rolling of HM corn did not improve digestibility of dry matter (P > 0.05), and percentage of whole kernels in feces of steers fed whole dried or whole HM corn was low (0.45 and 0.32%, respectively).

Thirty-two Holstein steers averaging 369 kg were used to evaluate the feeding value of high moisture barley (HMB). The HMB was harvested at 74.8–77.8% dry matter and ensiled whole in a concrete silo, or was treated with paraformaldehyde or organic acid mixture (propionic 80%, acetic 15% and benzoic acids 5%), and stored on a barn floor. Dry barley (DB) was harvested from the same field at a moisture level of 13.4%. Steers were fed barley ad libitum plus grass silage at the rate of 1.0% of body weight. At feeding, the dry matter content of the DB and HMB was higher than at harvesting. Total nitrogen was higher (P < 0.05) in ensiled HMB and paraformaldehyde-treated HMB compared to DB and organic-acid-mixture-treated HMB. Soluble nitrogen was reduced (P < 0.05) by the paraformaldehyde treatment. Cellulose was not significantly (P > 0.05) affected by any treatments. Daily gain, dry matter intake, feed efficiency, rib eye area, fat over 12th rib, 12th rib fat, bone and muscle were not influenced (P > 0.05) by the different treatments. Carcass yields were significantly (P < 0.05) higher for steers fed DB and ensiled HMB compared to those fed paraformaldehyde- and organic-acid-treated HMB.

High Moisture Corn

Two trials, involving a total of 144 pigs, were conducted to evaluate the effect of corn moisture content and preservation of corn with propionic acid on performance. Treating of corn containing approximately 76% dry matter with 1.5% w/w of propionic acid and storing in bins open to air resulted in no apparent problems in terms of heating or mold growth during storage. Pigs fed high moisture corn gained at a similar rate and had a feed efficiency equal to or better than pigs fed dry corn (90% dry matter). The addition of propionic acid to corn fed to pigs in groups improved rate of gain. A total of 13 pigs in the two trials died due to hemorrhaging the cause of which is unknown, but death did not appear related to dietary treatment.

Lambs were fed monensin (Rumensin®, monensin sodium, Eli Lilly and Co., Greenfield, Ind.) and a deaminase inhibitor 4,4’-dimethyldiphenyliodonium chloride (SmithKline Animal Health Products, West Chester, Pa.) (DAI) at 33 and 25 mg/kg of diet, respectively. Digestibility and ruminal volatile fatty acids were measured using five yearling lambs per treatment. There were no treatment effects on digestibility. Molar proportions of propionic acid were 93% higher when monensin plus DAI were fed than when lambs were offered the nonmedicated control diet. Feedlot performance was measured using eighty 18-kg crossbred lambs, with two pens of 10 lambs per treatment. Lambs fed DAI consumed 8% less feed than controls, though feed to gain ratio was not affected. Gains and feed efficiency with monensin were 8% and 5% higher (P < 0.05), respectively, than control values, though feed was utilized most efficiently when both monensin and DAI were fed.

Feeding Value

Studies of aerobic stability, digestion and growth performance were conducted with steers to determine the mode of action of a bacterial inoculant in altering the feeding value of ensiled high-moisture ear corn (HMEC); a comparison was made with propionic acid (PA) treated HMEC (10 g kg–1 fresh matter). The inoculant consisted of Lactobacillus plantarumand Enterococcus faecium, and was applied as an aqueous solution to provide 104 colony-forming units (cfu) per gram of HMEC. Inoculation of HMEC was not as effective as PA in improving aerobic stability, as assessed by changes in populations of yeasts and moulds. However, steers fed inoculated HMEC gained 11% more weight (P < 0.05) than animals fed untreated HMEC, and 9% more (P < 0.10) than those fed PA-treated material. There were no effects of treatment on food intake or digestion of organic matter (OM). At 4 h after feeding, rumen pH and molar proportions of isovalerate were greater (P < 0.05) with inoculated than untreated or PA-treated HMEC. Treatment differences in aerobic stability of HMEC did not account for the responses in growth performance. It appears that improvements in growth rate of beef cattle fed inoculated HMEC may be related to pH and/or the production of iso-acids in the rumen.
