- Abstract: Structural fiber inclusion in post-weaning piglet feeds has been previously demonstrated to improve growth performance and gut health. The objective of this study was to determine whether a pre-weaning inclusion of structural fiber (STR) would bring added value to piglet performance and gut health and if the potential benefits could be maintained at a later stage. A total of 26 litters, were creep fed either a control or high STR diet (HSTR; 4% oat hulls) for 10 d before weaning. Upon weaning, a total of 240 pigs (body weight: 6.7 ± 0.5 kg, 5 pigs/pen, 12 pens/treatment) of mixed sex, blocked by body weight, were randomly allocated to either a control or HSTR diet for 2 weeks. The experimental treatments were as follows, depending on pre- and post-weaning dietary intervention: control/control; control/HSTR; HSTR/control; and HSTR/HSTR. Oat hulls were added to expense of corn starch to produce the HSTR treatment diet. Diets were adjusted with wheat and soy oil to achieve equal amount crude protein and SID Lysine but had up to 40 kcal net energy difference. Pigs were fed a common diet for the rest of nursery phase. Data were analyzed by general linear model in R. Results indicated pig performance was not different at weaning. Addition of STR in the pre-weaning phase increased average daily gain in the last post-weaning phase ( P < 0.05), regardless of the post-weaning diets (Table 1). When HSTR was fed both in the pre and early post-weaning phase, greaterAbstract: Structural fiber inclusion in post-weaning piglet feeds has been previously demonstrated to improve growth performance and gut health.

Addition of STR in the pre-weaning phase increased average daily gain in the last post-weaning phase ( P < 0.05), regardless of the post-weaning diets (Table 1). When HSTR was fed both in the pre and early post-weaning phase, greater fermentation (indicated by numerically greater butyrate and caproate concentration in colon digesta) was observed at 21 d post-weaning. In conclusion, providing HSTR during pre-weaning phase improves performance during later nursery phase and if STR is used both pre- and post-weaning, gut fermentation is affected. … (more)
