“…T HE USE of corri (Zea mays L.) for silage as a ruminant feed is increasing. On an energy basis, corn silage is especially valuable for milk production ( 6,12). It has been reported that the energy value of corn silage was closely related to total grain yield and proportion of ears to stalks (2,3).…”

The effect of harvesting an early maturing corn hybrid when the grain was at the milk, as compared to well dented, on chemical composition, ear to plant ratio, grain and silage yield, digestibilities, palatability, and milk production was studied for 2 years. The ears of corn at the latter harvest as compared to the earlier harvest made up a considerably larger portion of the total silage yield. Correspondingly, the leaves, stalks, and husks were a smaller portion of the mature than of the immature corn plants. There was a large incrcease in silage and grain yields by delaying harvest to a more mature stage of growth. Each year the crude protein and crude fiber were significantly lower and the nitrogen‐free extract significantly higher for the silage harvested at the mature as compared to the immature stage. The total digestible nutrients values were slightly higher for the corn cut at the dent stage. The mature silage was more palatable than the immature silage. The persistency of milk production of the cows fed mature silage was slightly higher than for those fed immature silage.

Corn silage is the predominant mechanically harvested forage source for feedlot cattle production in the United States because of high yield. Alternatively, because of multiple cuttings per year and lower annual cost, the use of alfalfa or other forages, may increase opportunities for manure spreading, perennial soil cover, pollinator habitat, and greater carbon sequestration. The objective of this trial was to determine the feeding value of alfalfa haylage when replacing corn silage in growing cattle diets. One-hundred-sixty-five Angus crossbred steers [326 ± 51 kg of body weight (BW)] were blocked by initial BW and randomly assigned to one of 28 pens at the University of Minnesota feedlot. Pens were randomly assigned to dietary growing treatments. The control diet was comprised of (DM basis) 50% corn silage, 19.25% rolled corn grain, 19.25% high moisture corn, 7% dried distillers grains plus solubles, and 4.5% liquid supplement (corn silage control, CS Control). For alfalfa haylage (AH) diets, AH substituted corn silage at 33% (AH 33), 66% (AH 66), or 100% (AH 100). Growth performance measurements [dry matter intake (DMI), average daily gain (ADG) and gain to feed (G:F) ratio] were assessed for 42 to 70 d depending on BW block. Afterwards, steers were fed a common finishing diet until harvested. There was a linear increase in DMI (P < 0.01) with increasing AH inclusion. Replacing CS with AH linearly decreased (P ≤ 0.05) ADG and G:F. No differences (P ≥ 0.10) were observed in finishing performance or carcass traits. Results from this study demonstrated that greater substitution of corn silage with alfalfa haylage in growing diets resulted in greater intake but reduced rate of gain and gain:feed. Despite slower rate of gain, cattle fed alfalfa haylage at increasing proportions during the growing period were able to compensate in BW gains during the finishing period and reached harvest weight and backfat thickness at similar days on feed than those fed corn silage. Based on these results the energy value of corn silage and alfalfa haylage were 3.05 and 2.39 Mcal ME/kg of DM, respectively, when included at 50% of the diet DM.
