Dietary xylose as an energy source for young pigs
article
Energy balances were compared in eight pigs (6–8 kg) fed 5% glucose or 10% D-xylose added to a basal diet. In a carry-over design, each pig received the glucose and 2 weeks later the xylose diet or vice versa. The basal diet consisted mainly of barley, corn, soya flour and skim milk powder. Pigs were fed 1.3 times the maintenance requirement for energy. Energy balances were measured after 4 days of adjustment to the diet and over a 7 day period. The rate of weight gain was similar between the treatments. The metabolizable energy of 10% D-xylose was about equal to 5% glucose. The heat production was similar between treatments. This indicated that the absorbed and metabolized D-xylose is probably utilized to the same extent as or somewhat less than glucose, with the potential of some xylose being fermented in the large intestine and absorbed as volatile fatty acids. This could contribute to the well-being of the small pigs especially under situations of limited energy intakes.
