“…The starch (RS plus IST) found in the CM is extremely hard to remove, and is well established in the literature as resistant starch (RS 1 ) by ENGLYST, KINGMAN and CUMMINGS [13]. However, this starch has beneficial effects, contributing in the same way as ICW-Co as an insoluble dietary fiber as can be seen in the review by HARALAMPU [21].…”

“…RQ was rather high in these pigs during the nightly hours before the first meal, likely reflecting the oxidation of absorbed VFAs, and, particularly in barren housing, de novo fatty acid synthesis from VFA. The gradual and prolonged supply of energy from fermentation of RS potentially increases periods of satiety (Heijnen et al, 1995;Achour et al, 1997;Haralampu, 2000). As feeding motivation seems to increase the physical activity of pigs (Jensen et al, 1993;De Leeuw et al, 2005), fermentation processes could therefore be largely responsible for the reduced activity-related heat production in NSfed pigs, apart from possible specific effects of fermentation products on activity patterns (Schrama and Bakker, 1999).…”

Both dietary fermentable carbohydrates and the availability of straw bedding potentially affect activity patterns and energy utilisation in pigs. The present study aimed to investigate the combined effects of straw bedding and fermentable carbohydrates (native potato starch) on energy partitioning in growing pigs. In a 2 3 2 factorial arrangement, 16 groups of 12 pigs (approximately 25 kg) were assigned to either barren housing or housing on straw bedding, and to native or pregelatinised potato starch included in the diet. Pigs were fed at approximately 2.5 times maintenance. Nitrogen and energy balances were measured per group during a 7-day experimental period, which was preceded by a 30-day adaptation period. Heat production and physical activity were measured during 9-min intervals. The availability of straw bedding increased both metabolisable energy (ME) intake and total heat production (P , 0.001). Housing conditions did not affect total energy retention, but pigs on straw bedding retained more energy as protein (P , 0.01) and less as fat (P , 0.05) than barren-housed pigs. Average daily gain (P , 0.001), ME intake (P , 0.001) and energy retention (P , 0.01) were lower in pigs on the native potato starch diet compared to those on the pregelatinised potato starch diet. Pigs on the pregelatinised potato starch diet showed larger fluctuations in heat production and respiration quotient over the 24-h cycle than pigs on the native potato starch diet, and a higher activity-related energy expenditure. The effect of dietary starch type on activity-related heat production depended, however, on housing type (P , 0.05). In barren housing, activity-related heat production was less affected by starch type (16.1% and 13.7% of total heat production on the pregelatinised and native potato starch diet, respectively) than in strawenriched housing (21.1% and 15.0% of the total heat production on the pregelatinised and native potato starch diet, respectively). In conclusion, the present study shows that the availability both of straw bedding and of dietary starch type, fermentable or digestible, affects energy utilisation and physical activity of pigs. The effects of housing condition on protein and fat deposition suggest that environmental enrichment with long straw may result in leaner pigs. The lower energy expenditure on the physical activity of pigs on the native potato starch diet, which was the most obvious in straw-housed pigs, likely reflects a decrease in foraging behaviour related to a more gradual supply of energy from fermentation processes.

“…Thus, ileal starch digestibility in diets based on wheat, barley or rice may be over 0.95 (Canibe & Bach Knudsen, 2001;Sun et al, 2006), whereas it is reduced below 0.80 in sources with a high proportion of RS such as potato (Martin et al, 1998) or peas (Sun et al, 2006). In fact, RS is considered to behave physiologically as soluble dietary f ibre in the hindgut (Haralampu, 2000). Comparison of in vitro digestibility of diets based on 0.60 of rice, barley or maize indicates a hindgut contribution to overall organic matter digestibility of 0.09, 0.07 and 0.15, respectively (Pérez-Vendrell & Torrallardona, 2010).…”

A proportion of dietary starch reaches the hindgut, being fermented there. The characteristics of in vitro caecal fermentation and microbial community in pigs given different sources of starch were studied. Twenty-four Duroc × (Landrace × Large White) gilts given diets based on barley (B), broken rice (R), maize (M) or peas (P) (n = 6) for five weeks were slaughtered with 93.6 ± 6.41 kg. No differences (p > 0.10) were recorded in caecal pH, total short chain fatty acid (SCFA) and total bacterial concentration, nor in in vitro gas production from caecal contents, indicating the lack of a quantitative dietary effect on caecal environment. This could be partly due to the length of fasting time before slaughter (around 10 h). Molar SCFA proportions did not differ among diets; however, relative proportion of Lactobacillus sobrius/amylovorus as the species-type in starch digestion in hindgut of pigs, was highest with P diet (p = 0.010), and gas production from potato starch as substrate with P diet was highest at 2 h incubation (p = 0.012), and higher than B and R diets at 4 (p = 0.055) and 6 (p = 0.10) h incubation. Caecal bacterial biodiversity was higher for M and R diets than for P and B diets (Shannon index, p = 0.003). Sources of resistant or slowly digestible starch such as peas promote a microbial community with a different profile and higher capacity to ferment the starch arriving to the organ than other sources which are mostly digested in the small gut.
