High Fibre

The use of specific methods other than gravimetric ones to analyse fibre permitted a more precise study of the degradation of cell wall (CW) in the digestive tract. Digesta flow and rate of passage measurements have not been assessed previously in rabbits to investigate fibre digestion and fibre effects simultaneously in the proximal and in the distal segments of the tract. The effect of the level of dietary fibre on ileal and overall digestibility and rate of passage were studied by comparing semi-purified diets containing only one source of CW (dehydrated lucerne (Medicago sativa) meal) given to adult female rabbits. The effect of fibre particle size and adaptation period were also investigated. Measurements of fibre composition using both colorimetric and gas-liquid chromatographic techniques, showed that large amounts of (CW) were degraded in the caecocolic segments. Increasing dietary fibre level reduced the rate of passage but fibre degradation was increased, at the same time a lower digestive efficiency for energy in the small intestine was found. A small quantity of CW was apparently degraded before the caecum, assuming that the water-soluble fraction of CW was essentially implicated. Grinding lucerne meal through a 1 mm instead of a 3 mm screen did not improve CW digestibility in spite of a longer rate of passage in the caeco-colic segments. Adaptation to a high-fibre diet resulted in an higher digestive volume for colon and caecum, related to an improved degradation of CW. Furthermore, digestive efficiency in the small intestine appeared higher for rabbits adapted to a high-fibre diet than that for rabbits initially fed on a low-fibre diet.

AbstractCombinedin vivo(ileal cannulated pig) andin vitro(faecal inoculum-based fermentation) digestion methodologies were used to predict the production and absorption of SCFA in the hindgut of growing pigs. Ileal and faecal samples were collected from animals (n7) fed diets containing either 25 or 50 g/kg DM of kiwifruit fibre from added kiwifruit for 14 d. Ileal and faecal SCFA concentrations normalised for food DM intake (DMI) and nutrient digestibility were determined. Ileal digesta were collected and fermented for 38 h using a fresh pig faecal inoculum to predict SCFA production. The predicted hindgut SCFA production along with the determined ileal and faecal SCFA were then used to predict SCFA absorption in the hindgut and total tract organic matter digestibility. The determined ileal and faecal SCFA concentrations (e.g. 8·5 and 4·4 mmol/kg DMI, respectively, for acetic acid for the low-fibre diet) represented only 0·2–3·2 % of the predicted hindgut SCFA production (e.g. 270 mmol/kg DMI for acetic acid). Predicted production and absorption of acetic, butyric and propionic acids were the highest for the high-fibre diet (P<0·05), but these inter-diet differences were not observed for the ileal and faecal SCFA concentrations (P>0·05). In conclusion, determined ileal and faecal SCFA concentrations represent only a small fraction of total SCFA production, and may therefore be misleading in relation to the effect of diets on SCFA production and absorption. Considerable quantities of SCFA are produced and absorbed in the hindgut of the pig by the fermentation of kiwifruit.

Managing Stress

Understanding the distribution of Mãori across stages of health behaviour change (precontemplation, contemplation, preparation, action, maintenance) may inform the development of public health programs. In a replication and extension of a study by Nigg et al. (1999) we described the distribution of 73 Mãori male questionnaire respondents (age 18 to 59 years) across these stages for 8 healthy behaviours (avoiding dietary fat, eating fibre, reducing weight, regularly exercising, reducing stress, reducing sun exposure, using sunblock, and conducting cancer self-examinations). Respondents were also asked to rate their general health, health worries, and health locus of control. Evidence found of a continuum of change for ‘ignoring’, to ‘thinking about1 to ‘performing’ healthy behaviour provides moderate support for the idea that behaviour change is not an all-or-nothing event. There were no significant age effects. Respondents who rated their health more positively were more likely to report using sunblock, exercising regularly, and eating a high fibre diet. Respondents who felt they had more control over their health were more likely to eat a diet high in fibre. Eating a high fibre diet, exercising and managing stress were most strongly associated with the other health behaviours which may illustrate the concept of gateway behaviours proposed by Nigg et al. (1999).
