Grains produced by low-phytate barley and corn isolines homozygous for each species' respective low phytic acid 1-1 allele were compared to grain produced by near-isogenic normal or wild-type barley and corn in broiler chick feeds. Cobb x Cobb (384) chicks were used in a 10-d study. A randomized complete block design with a factorial arrangement of 2 x 2 x 3 was used with 4 replicates (8 chicks...

Several phenols and related compounds have been shown to have detrimental effects on insects while others have antibiotic activity against fungi which attack higher plants. Insects have also been implicated as contributors to preharvest contamination of corn [maize], Zea mays L, by aflatoxin. The objectives, therefore, were to determine (a) if commercial corn hybrids vary in their silk maysin c...

The objectives of this study were to partition corn grain into three digestible fractions and to measure the rate of disappearance of these fractions in vitro. Seventeen corn grain samples with varied fiber concentrations were extracted with either 80% ethanol or neutral detergent to obtain estimates of the pool size and digestion kinetics of the A, B1, B2, and C fractions. The carbohydrate sol...

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets we...

The present study was conducted to analyze the chemical composition, total phenolics content and antioxidant capacity of two whole corn (Zea mays) based meals traditional from Mexico: "traditional pinole" and "seven grain pinole"; and compare it with information available from ready to eat cereal products based on refined corn and whole grain cereals. Proximate analyses (moisture, ash, fat, pro...

Maize (Zea mays L.) is truly a remarkable crop species, having been adapted from its tropical origins to a wide diversity of environments and end uses. According to the Food and Agriculture Organization of the United Nations FAOSTAT webpage, 792 million metric tons of maize were produced worldwide in 2007, making it the world’s highest yielding grain crop (http://faostat.fao.org/site/339/defaul...

Improvement of USDA Select grade beef is essential for consumer acceptance of leaner beef. Seventy-two large- and medium-framed steer calves of mixed breeding were used in two experiments to evaluate feedlot performance, carcass composition, and beef palatability. Interactions of dietary energy level (corn concentrate or corn silage), breed type (Angus or Simmental), carcass electrical stimulat...

Corn is used to massively produce food for humans and domestic animals with grains of various taxonomic entities or races. For ruminants, the whole plant also as forage. In Argentina, both corn grain whole-plant silage are beef dairy cattle production. This paper aimed develop history perspectives grown silage, focusing on breeding. The importance fodder in its two variants (grain silage) has v...

The objective was to determine the effect of nutritional milieu of isolated stromal vascular (SV) cells on proliferative capacity of preadipocytes, and adipogenic and lipogenic capacity in adipocytes in vitro. Proliferation of the preadipocytes increased over time with 48 and 72 h being greater than 24 h; however, preadipocytes from steers supplemented with corn (LC) had lower proliferation rat...
