Urea metabolism in beef steers grazing Bermudagrass, Caucasian bluestem, or gamagrass pastures varying in plant morphology, protein content, and protein composition

JOURNAL OF ANIMAL SCIENCE, 85(8), 1997–2004.

By: G. Huntington n, J. Burns n & S. Archibeque n

author keywords: beef cattle; urea biosynthesis; Tripsacum dactyloides; Cynodon dactylon; Bothriochloa caucasica
MeSH headings : Animals; Blood Urea Nitrogen; Body Weight; Cattle / metabolism; Cynodon / chemistry; Cynodon / metabolism; Dietary Proteins / analysis; Esophageal Fistula / veterinary; Male; Plant Leaves / chemistry; Plant Stems / chemistry; Poaceae / chemistry; Poaceae / metabolism; Random Allocation; Urea / metabolism; Urea / urine
TL;DR: Urea production and recycling in these steers responded more to the N concentration in the grasses than to differences in plant protein fractions, and there was no evidence of improved N capture by the steers due to changes in the leaf:stem ratio among the Grasses at the herbage mass evaluated.
