title: [Effects of the presence of hydrolyzed amides in the diets of weaned piglets on the digestive utilization of various nutrients].
abstract: With a research carried out on early weaned piglets the effects of the presence in the diets of dextrose and partially hydrolyzed starch (maltodextrins), either alone or together, on the digestive utilization of some nutrients were evaluated. For this purpose 24 castrated males Landrace X (Large White X Duroc) with an average of 19 days were assigned to four homogeneous groups of 6 piglets each, reared in batteries and fed with the diets: A (control); B (5% dextrose); C (5% maltodextrins) and D (5% dextrose + 5% maltodextrins). The hydrolyzed products were in partial substitution of corn and barley flakes. The apparent digestibility of the nutrients in vivo was evaluated by means of Cr2O3, added as added as indicator to the diets in the quantity of 0,3%. The results show that both dextrose and maltodextrins alone improve the digestive utilization of dry matter, organic matter, nitrogen (only with 5% dextrose) and especially of energy; the effects of dextrose and maltodextrins together on the digestibility of these nutrients are lower, but higher in the case of minerals. The results partially corroborate those obtained with our previous researches and seem to indicate that 5% of hydrolyzed starch better the digestive utilization of nutrients through an improvement of the intestinal fermentations, but that 10% (5% dextrose + 5% maltodextrins) is a too large quantity.
