Abstract

¹H NMR metabolic profiles of urine from sheep exposed to prenatal nutritional restriction (n = 19) and a control group with normal prenatal nutritional requirements (n = 19), followed by either conventional (n = 10 + 10) or high carbohydrate high fat postnatal diet (n = 9 + 9), were studied. Urine was sampled from 2, 6, 19 and 24-month-old animals receiving differential dietary treatments during the first 6 months and the same normal diet later. Principal component analysis of ¹H NMR spectra (n = 164) showed a V-shaped metabolic trajectory as a function of age and diet, starting with urines with a high amount of glucose, indicative of monogastric-like metabolism, and exhibiting concomitant increase of metabolites related to rumen microflora (mainly glycine conjugates of benzoic and phenylacetic acid) as the ruminal metabolism developed. Urines from young (2-month-old) animals exposed to prenatal undernutrition followed by normal postnatal diet showed metabolic patters that are ahead in time on the metabolic trajectory relative to the prenatal control group. No long-term effects of fetal undernutrition, alone or in combination with postnatal hypernutrition were observed.
