N2 - Bacterial protein meal has a high content ofprotein but also of RNA and DNA. Sixteen barrows were allocated to four diets containing increasing levels of bacterial protein meal (BPM), from weaning to 80 kg live weight, to evaluate whether the RNA and DNA contents of BPM influenced the retention of nitrogen. It was hypothesised that an increased intake of RNA and DNA would lead to an increased urinary excretion of purine base derivatives and increased plasma concentrations. Retention of nitrogen was unaffected by dietary content of BPM (P=0.08) and the urinary excretion of purine base derivatives increased with increasing dietary content of BPM. No differences in fasting plasma concentration of uric acid, xanthine and hypoxanthine were observed. It can therefore be concluded that increasing levels of dietary BPM maintained protein accretion and led to changes in excretion of purine detrivatices, but did not cause uricogenic effects in the pigs.
