Total carotenoids (TC) were determined as a measure of total xanthophylls in grain flours and grits, by new validated spectrophotometric method based on A1cm1%-approach. The general analytical procedure is easily adjustable to different samples, the number of extraction steps depending on TC concentration in the sample. Basically, two methods have been suggested: the rapid one for low-TC sample...

John M. Marsh (406) 994-5621 [email protected] Increases in the demand for cornbased ethanol have contributed to substantially higher corn prices. For example, Central Illinois corn prices increased from $1.84/bushel in the fourth quarter of 2005 to $3.28/bushel in the fourth quarter of 2006, an increase of 78.3 percent (LMIC, 2006). Much of the increase in corn prices occurred during the fall...

This paper examines volatility transmission in oil, ethanol and corn prices in the United States between 1997 and 2011. We follow a multivariate GARCH approach to evaluate the level of interdependence and the dynamics of volatility across these markets. Preliminary results indicate a higher interaction between ethanol and corn markets in recent years, particularly after 2006. We only observe, h...

in order to effects of sulfur and manure on grain yield, yield components, and some physiological traits of corn hybrid ksc 704 in calcareous soils of kermanshah province, a factorial experiment was carried out based on a randomized complete block design with three replications. sulfur fertilizer in four levels 0, 250, 500 and 750 kg ha-1 and manure in four levels 0, 4, 8 and 12 t ha-1 were app...

The hairy fungus beetle, Typhaea stercorea (L.), occurs frequently in stored grain, often in large numbers. Populations infesting stored barley in Minnesota, corn in South Carolina, and wheat in Florida were sampled by means of grain probe traps. Spatial distribution of the species was examined by contour analysis of trap catch. In South Carolina, corn was sampled at 2 locations over 2 storage ...

Attaining high-quality corn silage is a critical aspect of profitability for corn and animal productivity. Biotechnology traits that reduce stress likely have more potential yield benefits for silage growers than even grain farmers. The corn genomes have been sequenced. We’ve put in thousands of markers that let us tag individual genes. Breeders have tools unlike anything they’ve had in the his...

Corn producers battle a variety of soil dwelling insect pests. Seedcorn maggots, wireworms, white grubs and several species of cutworms can attack either the seed or seedling plants and reduce the plant stand. Corn rootworm larvae feed on corn roots during midsummer and can significantly reduce the uptake of moisture and nutrients. Extensive feeding by corn rootworm larvae can reduce the roots ...

INTRODUCTION Cereal grains generally are the primary source of energy in feedlot diets. Availability of energy from the grain depends largely on the type of grain used as well processing of that grain (Owens et al., 1997). A variety of grain processing techniques are used including grinding, steam flaking, and compiling high moisture corn to ferment. Each processing method differs in its nutrit...

Physical properties of grain dust derived from five grain types (soybean, rice, corn, wheat, and sorghum) were measured and reported. The grain dusts were obtained from dust collection systems of terminal grain handling facilities and were assumed to be representative of grain dust generated during the handling process. The physical properties reported were as follows: particle size distributio...
