Fig. 1From: Metabolomics characterization of colostrum in three sow breeds and its influences on piglets’ survival and litter growth ratesTypical 1H–NMR spectrum of aqueous extract of colostrum. The spectrum has been split into three parts for the sake of clarity. Some resonances have been assigned by using Chenomx software and listed in Table 3: a Aliphatic or upfield region; b Carbohydrate or midfield region, characterized by the presence of signals belonging to sugars and glycerol and c Aromatic region or downfield regionBack to article page
