Professor, Department of Plant Pathology Cornell University Ithaca, New York 14853 May, 2001 Abstract Barley yellow dwarf virus (BYDV) and Cereal yellow dwarf virus (CYDV) are two aphidvectored, viral disease which most typically strikes small grains, especially barley, oats, and wheat. Limited research has been conducted regarding its reaction in sweet corn because BYDV/CYDV have not previousl...

A rumen protected fat product composed of Ca salts of fatty acids (CAF) was evaluated in beef cattle diets. Dietary treatments in a metabolism trial (six steers, 251 +/- 15 kg) and Feedlot Trial 1 (15 individually fed heifers, 355 +/- 11 kg) consisted of 62.1% corn and 3.2% soybean meal (C), 32.6% corn and 33.1% Kline barley (CB), and 28.2% corn, 33.1% barley, and 4.5% CAF (CBF) on a DM basis. ...

the objective of this study was to investigate the effects of summer savory essential oil (sseo) with cereals (based on barley or corn) on performance, rumen volatile fatty acid concentrations and some blood parameters of west azerbaijan native kids. in a randomized complete block design with a 3×2 factorial (0, 200 and 400 mg/d of sseo × barley or corn grain based diets) arrangement with 6 rep...

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...

In recent years the use of 2,4-dichlorophenoxyacetic acid (2,4-D) as a selective herbicide has become increasingly important in the production of small grains and corn. Yield reductions due to direct injury to the crops are usually small. However, severe yield reductions have occurred occasionally when 2,4-D was used at herbicidal dosages during certain stages of crop growth. Corn plants spraye...

Barley is a cereal grain that has demonstrated world-wide importance. Although generally considered an energy source, barley has more protein than other cereals commonly used in ruminant diets. Nutritional composition of barley can be affected by geographic location and climatic conditions. Varietal differences account for some of the differences observed in nutrient composition. However, it is...

Microbial protein synthesis in the rumen would be optimized when dietary carbohydrates and proteins have synchronized rates and extent of degradation. The aim of this study was to evaluate the effect of varying ruminal degradation rate of energy and nitrogen sources on intake, nitrogen balance, microbial protein yield, and kinetics of nutrients in the rumen of growing kids. Eight Boer goats (38...

To measure effects of diet on feedlot performance, carcass characteristics, and beef appearance, 144 crossbred beef steers (333+/-.44 kg) were allotted within weight block (3) to a randomized complete block design with a 2 x 3 factorial arrangement of dietary treatments. Main effects were grain (barley or corn) and level of potato by-product (PB) (0, 10, or 20% of diet DM). Steers were fed diet...
