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.

High Moisture Corn

Two trials were conducted involving 44 individually fed growing-finishing pigs to evaluate the effect of corn moisture content and method of processing of corn on performance. Digestible energy values of the diets were determined. When pigs had free access to feed and water, those fed high moisture corn consumed less dry matter and gained less rapidly than those fed artificially dried corn. The digestible energy values of diets containing whole corn were less than those of diets containing rolled or ground corn. The gain/feed ratio for diets containing whole corn was lower in the first trial but similar to other diets in the second trial.

High Moisture Corn

High-moisture corn samples (27% moisture) were inoculated with Lactobacillus plantarum and/or Propionibacterium shermanii and stored in sealed containers or under carbon dioxide atmosphere for 60 d at 26°C. Growth of the inoculated organisms was observed in the corn, and the final pH of inoculated samples was significantly lower than the final pH of uninoculated samples. Mold growth was prevented in all samples, and the initial yeast population was drastically reduced in those samples inoculated with P. shermanii. Inoculation with L. plantarum accelerated acid production in the early stages of the fermentation. Flushing with carbon dioxide did not alter the fermentation but resulted in a slightly lower final moisture content.

Abstract Exogenous fibrolytic enzymes (EFE) improve the energy availability of grains for nonruminant animals by reducing encapsulation of the endosperm nutrients within grain cell walls; however, these benefits are unknown in the treatment of corn-based silage for cattle. The objective of the present study was to evaluate the effects of adding EFE at ensiling on the nutritive value of high-moisture corn (HMC) and snaplage (SNAP) for finishing Nellore bulls. The EFE dose was 100 g/Mg fresh matter in both HMC and SNAP. Diets were 1) a SNAP + HMC control (without enzyme addition); 2) SNAP + HMC EFE (with enzymes); 3) a whole-plant corn silage (WPCS) + HMC control (without enzyme addition); and 4) WPCS + HMC EFE (with enzymes). In addition to the silages, the diets were also composed of soybean hulls, soybean meal, and mineral–vitamin supplement. The statistical design was a randomized complete block with a factorial arrangement of treatments, and the experiment lasted 122 d. For in situ and in vitro analyses, 2 cannulated dry cows were used. There was no interaction between the diets and EFE application (ADG, P = 0.92; DMI, P = 0.77; G:F, P = 0.70), and there was no difference between the SNAP and WPCS diets regarding the DMI (P = 0.53), ADG (P = 0.35), and feed efficiency (ADG:DMI, P = 0.83). Adding EFE to the HMC and SNAP at ensiling did not affect ADG but decreased DMI (P = 0.01), resulting in greater feed efficiency by 5.91% (P = 0.04) than that observed in animals fed diets without the addition of EFE. Addition of EFE to HMC resulted in reduced NDF content and increased in vitro and in situ DM digestibility compared with untreated HMC. No effects were found for the addition of EFE to SNAP. Fecal starch decreased with EFE application (P = 0.05). Therefore, the diet energy content (TDN, NEm, and NEg) calculated from animal performance increased (P = 0.01) with the addition of EFE to HMC. In conclusion, exchanging the NDF from WPCS with that from SNAP did not affect the performance of finishing cattle, whereas the addition of EFE to HMC at ensiling improved animal performance by increasing the energy availability of the grain.

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).

SUMMARYAn experiment is described in which plots of a silt loam soil were compacted by ploughing and rotary cultivation when the moisture content was high. Kale and barley were grown on these plots in 2 years.Compaction of the soil was not as great as anticipated, but there were marked reductions due to wet cultivation in the dry-matter yield of kale and the vegetative growth of the young barley. Seed yield of barley was relatively unaffected, although there was a significant reduction due to wet ploughing in one year.The implication of these results for experimentation on the effects of soil structure on crop yield are discussed.

Three experiments were conducted to determine the effects of monensin on feed intake, rate of gain and feed efficiency of a total of 198 Holstein steers. In experiment I, 72 steers were fed ground ear corn and corn silage diets containing 0 (treatment 1), 22 (treatment 2) and 33 (treatment 3) g/tonne DM monensin for 112 days. Treatments 2 and 3 received 11 g/tonne DM monensin for the first 28 days. Daily gains were not significantly different (P > 0.05) throughout the trial and intake was slightly reduced (P > 0.05) with monensin addition. Feed efficiency in treatments 2 and 3 were improved 5.5 and 8.8% respectively, but only treatment 3 was significantly (P < 0.05) better than treatment 1. Rumen fluid from steers fed treatment 3 contained a higher proportion (P < 0.05) of propionic acid and a lower (P < 0.05) A:P ratio than did rumen fluid from treatment 1. Levels of acetic and butyric acid were reduced (P > 0.05) by monensin inclusion. In experiment II, 46 steers were fed hay crop silage and shelled corn diets containing 0 (treatment 1) and 33 g/tonne DM (treatment 2) monensin for 112 days. Gains were slightly (P > 0.05) higher and intake slightly (P > 0.05) lower on treatment 2. Monensin improved (P > 0.05) feed efficiency by 8.5%. In experiment III, 40 purchased and 40 station-reared steers were assigned by origin, in pairs, to 40 Calan electronic headgates. A 23 factorial experimental design was used to evaluate the effect of diet with or without monensin used separately and in combination with progesterone-estradiol implants. Steers were fed a high moisture ear corn and corn silage diet for 84 days. No 3-factor interactions (P > 0.05) were detected. Implant treatments gained significantly (P < 0.05) faster than either control or monensin alone. Intake was significantly (P < 0.05) lower in treatments fed monensin. Feed efficiency was improved (P < 0.05) 16% with both monensin and implant, 10% (P < 0.05) with monensin alone, and 6% (P > 0.05) with implant alone over control.
