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 ...

Depression of rumen ammonia and blood urea by quebracho tannin-containing supplements fed after high-nitrogen diets with no evidence of self-regulation of tannin intake by sheep
(Elsevier Science, 2012-06)
The aim of this study was to assess whether sheep enhance nitrogen use in response to tannin supplementation, and if they increase preference for tannin-rich supplements when consuming diets high in rumen-degradable protein. ...
Intake and ruminal parameters of goats fed diets supplemented with vegetable oils
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2021-01-01)
The objective of this study was to evaluate the intake and ruminal parameters of goats fed diets supplemented with vegetable oils. Four rumen-cannulated Saanen goats were allocated to four treatments, which consisted of a ...
Efeitos de dietas com níveis crescentes de milho no metabolismo ruminal de energia e proteína em bubalinos
(Sociedade Brasileira de Zootecnia, 2009)
Avaliaram-se os efeitos de dietas com níveis crescentes de milho em grão moído (0, 22, 37 e 49% na MS) em substituição ao feno de coast-cross mantendo-se diferentes relações proteína:carboidratos não-fibrosos (PB:CNF = ...
Diurnal Concentration of Urinary Nitrogen and Rumen Ammonia Are Modified by Timing and Mass of Herbage Allocation
(2019)
The objective of this work was to evaluate whether changes in time of herbage allocation and herbage mass (HM) (low (L) or medium (M)) modify the diurnal pattern of urinary nitrogen (N) concentration and ruminal ammonia ...
