The growing ethanol industry in the Southern Great Plains has increased the use of wet distillers grains with solubles (WDGS) in beef cattle (Bos taurus) finishing diets. Few studies have used steam-flaked corn (Zea mays L.; SFC)-based diets to evaluate the effects of WDGS in finishing cattle diets, and a reliable estimate of the net energy value of WDGS has yet to be determined. Effects of cor...

net) with the maximum-likelihood algorithm and a boot-strap of 1,000 replicates, we constructed a phylogenetic tree (online Technical Appendix Figure). All 8 sequences clustered within subtype 4d of HEV. The sequences were similar to each other (95.5%–99.8% similarity in nucleotide sequence) and similar to sequences reported for other cattle (83.3%–85.3%; online Technical Appendix Figure). More...

background: organic acids refer to a family of compounds that are intermediates in a variety of metabolic pathways. many organic acids are present in urine from clinically normal individuals. elevated levels of urine organic acids cause to the organic acidurias, disorders in which some metabolic pathways in organic acid metabolism are blocked. the present work identified major and minor urinary...

The objectives were to characterize the effects of supplemental CP concentration and ruminal degradability in barley-based finishing diets on microbial protein synthesis, ruminal fermentation and nutrient digestion, and route and chemical form of N excretion in beef cattle. Four Angus heifers (564 ± 18 kg BW) with ruminal and duodenal cannulas were used in an experiment designed as a 4 × 4 Lati...

screening interval urinalysis has long been considered essential to pediatric health care. a urinalysis is recommended at four times: in infancy, early childhood, late childhood, and in adolescence. several chemical parameters can be measured as commercially available in dipstick test. this test is relatively inexpensive and it takes less than 5 minutes to be completed. in a 3 month follow up p...

exposure to mercury (hg) as a heavy metal can cause health effects. the objective of this study was to assess occupational exposure to hg in a chlor-alkali petrochemical industry in iran by determining of hg concentrations in air, blood and urine samples.the study was performed on 50 exposed subjects and 50 unexposed controls. air samples were collected in the breathing zone of exposed subjects...

In 1858 H. S. Thompson, writing in the “Journal of the Royal Agricultural Society”, quoted an ancient Persian proverb, “The sheep has a foot of gold, and turns to gold whatever it touches”, and wrote that, although at first he agreed with the proverb, he rapidly became dissatisfied with it. In his experience-sustained yheavystockifig-w? sheep caused pastures to deteriorate. In my opinion his im...
