“…Ear to stover ratios were not given. Dunn et al (1955) found fully-dented maize grain in silage to be equivalent in feeding value to dry maize grain. Jorgensen et al (1969) stated that high-producing dairy cows need a total ration containing 75% or more total digestible nutrients (TDN) and that doubling the ear content of maize silage that contains 50% or more of ears could increase TDN content 3.5% or more.…”

Maize (Zea mays L.) is used extensively as a silage crop. A relatively simple method is needed to evaluate hybrids for that purpose. Six maize hybrids, two each in early, midseason, and medium‐late maturity classes, were grown at four population densities over a 3‐year period. The hybrids were chosen on the basis of superior grain yield for their respective maturity class in previous tests. Populations were established at 34,600, 44,500, 54,300, and 64,200 plants per hectare. Data were obtained for each hybrid at each planting rate for grain and forage yield and on several other traits, including component plant: part ratios. The early hybrids tended to be lower in grain yield, total dry weight, weight per ear, moisture at harvest, ear height, plant height, and proportion of stalks but higher in proportion of ears than the later hybrids. Shelling percentage, proportion of leaves, and stalk diameter showed differences between hybrids but no trend among maturity groups. As population densities increased, total dry matter increased, whereas weight per ear, stalk diameter, and percent erect plants decreased. Plant and ear heights changed very little with changes in population density. Plants tended to become proportionately smaller as populations increased so that plant‐part ratios remained nearly the same. Barren plants were not included in the separation samples. Percent barren plants increased significantly with increased population density. High energy feeds are needed by high‐producing, lactating cows and cattle on finishing rations. Maize parts vary greatly in digestibility. In the absence of feeding trials, plant‐part separation data and total dry matter production may be the most useful indicators of the relative values of maize hybrids for silage.

“…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). Allowing corn plants to mature increases both grain yield and ear-to-stalk ratio according to Nevens et al (9).…”

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.

“…Huffman and Duncan (1954), reporting animal feeding trials, concluded that corn silage should not be considered as a roughage, but as a mixture of a roughage and grain. Dunn et al (1955) concluded that grain in corn silage had the same value for milk production as corn grain fed in the form of dry corn and cob meal. Morrison (1956) indicated that the grain portion of forage corn was higher in percentage of digestibility, when compared to the leaves and the stover.…”
