Excretion of Creatinine and Creatine by Beef
In the classical theory of protein metabolism proposed by Folin (1) two types of protein metabolism are recognized, one a constant or endogenous metabolism, and the other a variable or exogenous metabolism. According to this theory the endogenous metabolism is represented by the excretion of creatinine at a relatively constant rate which is independent of protein intake. More recently, as point...
متن کاملIII. Quantitative aspects of phosphorus excretion in ruminants.
Ruminant phosphorus excretion and metabolism were studied through a database. Faecal endogenous phosphorus is the main pathway of phosphorus excretion and averages 0.85 of total faecal phosphorus. The remaining 0.15 is unabsorbed dietary phosphorus. Faecal endogenous phosphorus is mainly unabsorbed phosphorus, with saliva being the major source, and is correlated to factors influencing saliva s...

متن کاملDietary nitrogen – definitions, digestion, excretion and consequences of excess for grazing ruminants
New Zealand pastures often contain a higher concentration of nitrogen (N) than required by ruminants, and this can be exacerbated by application of N fertilisers to boost pasture growth. Excess dietary nitrogen (N) has negative implications for environmental sustainability and animal production, but producers and rural professionals are sometimes unaware of these issues and especially the termi...
متن کاملThe Effect of Light on Creatinine and Creatine Excretion and Basal Metabolism.*
Thus far, Hoogenhuyze and Best (1) have been the only investigators foundwho haveworked on the influence of light on the formation of creatinine. The light which they used was from 88 incandescent lamps of 16 candle power each, placed along the four sides of a wooden cabinet lined with zinc. The subject was placed in the cabinet for $ hour with only his head out of the opening at the top. The t...
