1. The European corn borer larva has been shown to require a dietary source of one or more unidentified factors contained in corn leaves, grass juice concentrate, and certain other plant materials. The required factor or factors has been termed the corn leaf factor. 2. The corn leaf factor does not appear to be identical with any of the known B vitamins, or with ascorbic acid, sodium nucleate, ...

Preconditioned steer calves weighing 690 lbs were fed diets containing on a dry basis 0, 24.9 and 47.0 percent modified wet distillers grains (DGS) for 186 days. Wet DGS replaced a portion of corn and supplement in a diet containing dry rolled corn, corn silage, tub-ground corn stalks and supplement. Steers were implanted initially with Component E-S and terminally with Component TE-S. Daily ga...

Beef finishing and dairy lactation experiments were conducted to evaluate the nutritional value of distillers grains (DG) from sorghum or corn fermentation, in both wet (35.4% DM) and dry (92.2% DM) form (dairy trial only). In the finishing experiment, 60 yearling steers were used in a completely randomized design with three diets that were fed for 127 d: 1) control diet with 86% (DM basis) dry...

This study evaluated fermentation characteristics and fungal numbers of napiergrass silages prepared with and without added raw or heated corn meal (10%, fresh-weight basis) at ensiling. Corn was added to napiergrass so that the silage would contain concentrate similar to that of corn silage with minimum grain content. The silages treated with raw or heated corn were fed to dairy does to compar...

Over a 3-yr period 336 MT/ha of dried sewage sludge, from a municipal waste treatment plant, was applied in liquid form to land subsequently used to grow corn. The sludge contained 115 mg Cd, 4,200 mg Zn and 538 mg Ni/kg dry matter and comprised the solids remaining after treatment of the waste waters of approximately 260 industries as well as domestic users. Corn grain harvested from the plot ...

Six experiments were conducted to evaluate methods for measuring NDF in corn and distillers grains plus solubles. Methods included using sodium sulfite, α-amylase (AMY), amyloglucosidase, heat and steam with an autoclave, grinding methods, and a pre–fat extraction to decrease factors that interfere with measuring NDF accurately. Using sodium sulfite and AMY resulted in decreased (P < 0.01) corn...

Two experiments were conducted to evaluate the nutritional quality of 2 varieties of Purdue high-digestible sorghum (PHD1 and PHD2) and a normal sorghum, compared with corn, in diets of pigs and broiler chicks. In Exp. 1, 12 pigs (average BW, 55 kg) fitted with ileal T-cannula were fed 4 diets containing 946 g of corn or sorghum (PHD1, PHD2, and normal) per kg in a 2-period crossover design (i....

A finishing experiment evaluated substitution of corn with corn silage in diets with modified distillers grains with solubles (MDGS). Steers were fed 15, 30, 45, or 55% corn silage in diets with 40% MDGS. Two additional treatments were tested with 30% corn silage and 65% MDGS and 45% corn silage and 0% MDGS. As corn silage inclusion increased, there was a slight linear increase in F:G with a li...

The influence of including 20% whole corn, differing in grain hardness, on the performance, nutrient utilization and gut characteristics of broiler starters was investigated. The experimental design was a 3 × 2 factorial arrangement of treatments evaluating corn hardness (hard, semi hard or soft) with diets based on ground corn or 20% of ground corn replaced by whole corn. The 3 corn cultivars ...
