The objective of this experiment was to evaluate a transgenic source of corn grain containing the event DAS-Ø15Ø7-1 (TC1507) when included in diets fed to growing and finishing pigs. The commercial product trait name of TC1507 corn is Herculex I; this corn grain contains the cry1F gene from Bacillus thuringiensis var. aizawai and the phosphinothricin acetyltransferase (pat) gene from Streptomyc...

Purpose: To optimize the process conditions and analyze in vitro digestibility of corn starch phosphodiester prepared by sodium trimetaphosphate (STMP). Methods: By using response surface method, the effects of STMP concentration, pH, esterification temperature, and urea addition on digestion resistance of corn starch phosphodiester were investigated and optimal conditions were determined. Corn...

The European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae) has been a major pest of corn and other crops in North America since its accidental introduction nearly a hundred years ago. Wide adoption of transgenic corn hybrids that express toxins from Bacillus thuringiensis, referred to as Bt corn, has suppressed corn borer populations and reduced the pest status of this insect i...

Seasonal fluctuations in field populations of Meloidogyne incognita, Pratylenchus zeae, P. brachyurus, Criconemoides ornatus, Trichodorus christiei, and Helicotylenchus dihystera on monocultured corn, cotton, peanut, and soybean were determined monthly for 4 yr. Population densities of M. incognita were greater in corn and cotton plots than in peanut and soybean plots from July until January. T...

Corn grain containing a relatively high concentration of radioactive phosphorus was needed for a poultry feeding investigation by the Poultry Husbandry Department at the University of Connecticut at Storrs. A gravel nutriculture procedure was decided upon for growing the corn. Uniformity of maturity was desired so a hybrid field corn (Connecticut 520) was selected as the corn to be grown for th...

In terms of risk, second year corn fields have a 25-35% chance of risk for rootworm damage, third year corn a 50-70% risk of losses from corn rootworm larval feeding and fourth year corn risk for rootworm losses...

Wisconsin dairy farmers produce more corn (Zea mays L.) silage than any other state in the U.S. A University of Wisconsin corn silage research consortium evaluated corn hybrids and found that the range for NDF and digestibility among commercial hybrids is narrow, but more importantly, yield and quality differences among corn hybrids were repeatable (Coors, 1996). In 1995, an extension program w...

Eighty-five fungi isolated from prepared feed and from corn collected on farms were grown separately in moist autoclaved corn. The corn was fed to virgin weanling rats for 5 to 12 days; the rats were then killed, and their uteri were removed and weighed. Twelve isolates of Fusarium from corn and one from poinsettias caused increases of five to eight times in weight of the uterus as compared wit...

Forty-five energy balances were completed with 12 multiparous, lactating Holstein cows in a study designed to determine the energy content of wet corn distillers grains. Treatments were applied in a repeated switchback design and consisted of total mixed diets containing 31.4% corn silage, 18.4% alfalfa hay, and either 30.7% rolled corn and 16.7% soybean meal or 17.0% rolled corn and 31.2% wet ...
