British × Continental steers (n = 168; 7 pens/treatment; initial BW = 362 kg) were used to evaluate the effect of dose/payout pattern of trenbolone acetate (TBA) and estradiol-17β (E2) and feeding of zilpaterol hydrochloride (ZH) on serum urea-N (S

Relationship of whole body nitrogen utilization to urea kinetics in growing steers1

Autor: Derek Brake, M. L. Jones, K.S. Spivey, Evan C. Titgemeyer, S. L. Parr

Publikováno v: Journal of Animal Science. 90:3515-3526

Urea kinetics were measured in 2 experiments, with treatments designed to change protein deposition by the animal. Our hypothesis was that increased protein deposition by cattle (Bos taurus) would reduce urea production and recycling to the gastroint
