The rate and pattern of urea infusion into the rumen of wethers alters nitrogen balance and plasma ammonia
(Wiley Blackwell Publishing, Inc, 2014-12)
Changes in N balance, urinary excretion of purine derivative (PD), urea, creatinine and ammonia and plasma ammonia, glucose, urea, insulin and IGF-1 were examined in four wethers (37 ± 2.6 kg BW). The animals were fitted ...
Amine functionalization of carbon nanotubes with solid urea using different plasma treatments
(2022-05-01)
Carbon nanotubes (CNTs) were amine-functionalized through treatments in inductively coupled post-discharge, capacitively coupled micro spark and pulsed micro arc/glow discharge plasma regions, using urea in solid state as ...
Short-term urea feeding decreases in vitro hatching of bovine blastocysts
(ELSEVIER SCIENCE INC, 2011)
Cows fed high-protein diets may have impaired reproductive performance. Although the pathogenesis has not been completely elucidated, it appears that not only the uterus, but also the follicle and oocyte, are affected by ...
Nitrogen excretion during embryonic development of the green iguana, Iguana iguana (Reptilia; Squamata)
(2012-10-01)
Development within the cleidoic egg of birds and reptiles presents the embryo with the problem of accumulation of wastes from nitrogen metabolism. Ammonia derived from protein catabolism is converted into the less toxic ...
