Urinary benzylated compounds as potential markers of forage intake and metabolism of their precursors in ruminants

Pagella, Jose Horacio January 1998 (has links)
The quantitative relationship between the urinary excretion of <I>TBA</I> and the uptake of <I>PPA </I>and <I>CHCA</I> was examined by continuous intraruminal infusion of <I>PPA</I> (8, 16 or 24 mmol/d) either alone or with <I>CHCA </I>(8 or 16 mmol/d) in sheep nourished by intragastric infusions of all nutrients. The daily excretion of <I>TBA</I> was linearly correlated (<I>r</I> 0.99, <I>P</I><0.001) with the amounts of <I>PPA</I> and <I>CHCA</I> infused. The urinary recovery of infused <I>PPA</I> and <I>CHCA</I> as <I>TBA</I> was 0.79 (<I>s.e.</I> 0.01). Recovery of infused <I>SA</I> (8 mmol/d) as urinary total salicylic acid (<I>TSA</I>) was 0.89 (<I>SD</I> 0.08). Both <I>TBA</I> and <I>TSA</I> excretions were found to be exclusively of exogenous origin, with negligible faecal excretion. It is concluded that urinary <I>TBA</I> is a potential estimator of <I>PPA + CHCA</I> absorption from the digestive tract. <I>SA</I> may have potential as a marker of urine volume. The relationship between urinary excretion of <I>TBA</I> and forage intake was assessed with steers fed different amounts of fresh herbage from pastures comprising oat, rye, vetch and lucerne. Herbage samples collected daily were incubated <I>in vitro</I> with buffered rumen fluid for 48 h. The <I>PPA</I> production per unit of herbage <I>DM</I> incubated was fitted to the exponential function of time <I>Y </I>= <I>a +</I> [<I>b</I>. (1 - <I>e</I><sup>-<I>c.l</I></sup>)]. Regression analysis showed that the <I>TBA:</I>creatine concentration ratio was a good explanatory variable (<I>r</I><sup>2 </sup>0.92-095; <I>P</I><0.001) of herbage intake. <I>TBA</I>:creatinine concentration ratio divided by the product <I>b.c</I>, both constants from the fitted curves of <I>PPA</I> production of herbage cultures, was another good index (<I>r</I><sup>2</sup> up to 0.98). It is concluded that a method for the prediction of herbage intake for grazing animals based on <I>TBA</I> excretion in urine seems promising.
