The present study was undertaken to provide detailed information on the effect of dietary fibre (DF) level on body composition, visceral organ weight, nutrient digestibility and on energy and protein metabolism of rats housed in cold (16°), warm (24°) or hot (32°) thermal environments. High- or low-fibre diets (257 v. 56 g DF/kg dry matter (DM)) were studied in a 6-week balance experiment (initial body weight about 100 g). Heat production was measured using open-air circuit respiration chambers. Pea fibre and pectin were used to adjust the DF level in the high-fibre diet. The ranking order of daily gain of rats kept in different environments was: 24°>16°>32°, while the ranking order for carcass protein was: 16°>24°>32°. Rats on the high-DF diet had a lower daily gain than those on the low DF diet, and more protein in DM of empty body weight (EBW) and less fat. The relative weights (g/kg EBW) of liver, heart and kidney decreased when increasing the environmental temperature. The relative weight of the heart was highest in rats on the high DF level, while liver and kidney weights were unaffected by DF. Per kg EBW, the stomach, small intestine, caecum and colon and the length of colon were significantly greater in rats consuming the high-fibre diet compared with those on the low-fibre diet. Rats kept at low temperature had a significantly heavier gastrointestinal (GI) tract than those kept at the highest temperature. Digestibility of protein, DM and energy was lowest for rats fed on the high-fibre diet. Heat production (HP) of fed rats as well as fasting HP decreased significantly as environmental temperature increased. HP as a proportion of metabolizable energy (ME) was significantly lower for rats at 24° compared with the other environmental temperatures. The proportion of energy retained as protein was slightly higher in rats fed on the high-fibre than on the low-fibre diet. Based on the results of the present study the authors measured a net energy value of 5·4 kJ/g DF fermented; approximately 50% of the DF came from peas. Possible implications of the present findings are discussed.

Dietary Fibre Intake

1. Eighty-eight healthy omnivores with normal blood pressure participated in a randomized, controlled, cross-over trial of the effect on blood pressure of increasing dietary fibre intake. Subjects were randomly allocated to a control group eating a low fibre diet throughout, or to one of two experimental groups eating a high fibre diet for one of two 6-week experimental periods. Changes in body weight, other dietary constituents and lifestyle factors were avoided as far as possible. 2. Twenty-four hour diet records showed a substantial increase in dietary fibre when subjects were on the high fibre diet. 3. There was no consistent effect of change in dietary fibre intake on group mean systoloic or diastolic blood pressures. Adjusting blood pressures for changes in other dietary components, plasma lipids, electrolytes, body weight and other lifestyle variables did not alter this result. 4. These findings do not support the hypothesis that the blood pressure lowering effect of a vegetarian diet is solely due to an increase in fibre intake.

Urine and faeces production, water intake and body condition were investigated in 19 pregnant gilts fed a concentrated (CONC: 2 kg d−1, 2.2% CF) or high-fibre diet (HF: 3.6 g d−1 20.4% CF). Gilts fed HF drank less (P < 0.05) than CONC, but urine excretion did not differ significantly. More faeces were excreted by HF than CONC (P < 0.001), with similar dry matter contents. Total daily manure production, body weight and backfat thickness were similar among treatments. Key words: Fibre, sow, manure, urine, faeces, gestation

Ad Libitum

<p>Restriction of young rabbit females during rearing is a widespread management technique that could have negative consequences on their welfare and behaviour. In the present work, a total of 24 young rabbit females aged 9 wk were used to evaluate 3 rearing feeding programmes until first parturition: CAL, fed ad libitum with a control diet [C: 11.0 MJ digestible energy (DE) and 114 g digestible protein (DP) per kg dry matter (DM)]; CR, receiving the C diet restricted (140 g/d) from 12 wk of age; and F, fed ad libitum with a low energy/high fibre diet [F: 8.7 MJ DE and 88 g DP per kg DM]. F females presented lower body weight than CAL and CR females at week 18 (–0.4 kg and –0.2 kg; P&lt;0.05), but differences in body weight disappeared at parturition. Feeding programme affected the daily feed intake of young females during rearing and gestation periods (on av. of 2 periods: 140, 127 and 179 g DM/d, for CAL, CR and F females, respectively; P&lt;0.001). Blood levels of glucose and insulin decreased with the age of rabbits (from 97 to 73 mg/dL for glucose and from 11 to 6 μUI/mL for insulin at 13 and 20 wk, respectively; P&lt;0.001). Concentration of non-esterified fatty acids was higher in the blood of CAL females (+0.13 mmol/L compared to F; P&lt;0.05), while corticosterone was higher in F females (+0.7 μg/dL compared to CAL; P&lt;0.05). The type of feeding schedule affected the lying still and eating behaviour (P&lt;0.01) of CR females, especially before and after feeding supply, as well as their behavioural stressed indicators (stereotypies; P&lt;0.01), which were more frequent in CR females before feeding supply at 20 weeks of age. Therefore, ad libitum use of a low energy/high fibre diet is an adequate feeding programme for young rabbit females, which does not alter their behavioural patterns.</p>

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).
