Angus-cross steers (n = 20; 261 ± 21.5 kg BW) were used to examine how early exposure to high concentrates or high quality forages altered marbling deposition and lipid metabolism. Steers were randomly assigned to high concentrate diet (CONC) or hig

Endophyte-infected tall fescue (E+) produces ergovaline and ergovalinine, which are mycotoxins that act as dopamine agonists to suppress prolactin and induce vasoconstriction. The experiment was designed as a 3 × 2 × 2 factorial with DRD2 genotype

Forty Angus-cross steers (280 ± 21.4 kg BW, 8 mo.) were used to examine the effects of exposure to 2 diets [high concentrate diets (CONC) versus high quality forages (FOR)] during 2 time periods [early (EARLY; at 30-d post weaning) or late (LATE; ju

Backgrounding or stocker operations attempt to add value to calves by efficiently adding weight and predominately taking advantage of the protein accretion phase of development, ultimately preparing calves for later stages of production. The objectiv

Consumption of ergot alkaloids during the second half of gestation have been shown to decrease umbilical artery vasoactivity resulting in lighter birth weights. The objective was to evaluate vasoactivity of serotonin (5HT) receptors 5HT2A and 5HT1B/1
