| Description: |
International audience ; Most feed tables contain nutritional values for feedstuffs in mash form, which are used to formulate diets subjected to technological treatments such as pelleting. The present study aimed to compare the performance of growing pigs fed pelleted diets formulated with reference to mash nutritional values. Growing-finishing diets were formulated with a single starch source (M diets: maize, B diets: barley or W diets: wheat and wheat bran) of a 50:50 blend of B and W (B-W diets), with a net energy (NEMash) content of 9.9 (M diets) or 9.4 (B, B-W, W diets) MJ/kg. The NE content after pelleting (NEPellet) was assessed based on recent results from the literature: 10.3, 9.5, 9.6 and 9.7 MJ/kg for M, B, B-O and W diets, respectively. Sixteen replicates of four pens of seven pigs were studied at a body weight (BW) of 31-117 kg. Although fed ad libitum, B and B-W pigs did not increase their daily feed intake (DFI, 2.70 kg/d on average) above that obtained with M (mean of 2.69 kg/d), which resulted in less intake of NEMash or NEPellet than that with M (P < 0.01). With W diets, DFI tended to be lower (2.62 kg/d, P = 0.06) than that with B or B-W diets, which may have been related to the higher NEPellet content of W diets. Subsequently, a similar intake of NEPellet and energy conversion ratio (MJ NEPellet/kg BW gain) were obtained for these diets. These results were consistent with the similar backfat thickness at slaughter for pigs fed the B, B-W and W diets (mean of 22.3 mm vs 23.9 mm with M diets, P < 0.01). Accounting for the effect of pelleting on the NE content of cereals helps to remove the discrepancy observed between the different performance criteria when flour values are used. ; Les valeurs nutritionnelles des tables sont obtenues à partir de régimes présentés sous forme de farine, mais utilisées pour formuler des aliments subissant des traitements technologiques.
