“…For physical activity it is not always clear whether authors made this correction. As dietary fibres prolong eating time (11,12,18,23,39,41,43,44,46) and sows feed in standing posture, postprandial physical activity in sows fed fibrous diets could be overestimated when feeding time is not taken into account (for example, see Ramonet et al (43) and Robert et al (44) ). In growing pigs studies on behavioural effects of dietary fibres are lacking.…”

Effects of dietary fibre on behaviour and satiety in pigs

During the past decades there has been considerable interest in the use of dietary fibre in both animal and human nutrition. In human subjects dietary fibre has been studied intensively for possible effects on body-weight management and health. In animal nutrition the interest in dietary fibre has increased because it can be used as a cheap source of energy and because of its potential to improve animal welfare and reduce abnormal (mainly stereotypic) behaviour. Animal welfare is impaired if the diet does not provide sufficient satiety, combined with an environment that does not meet specific behavioural requirements related to natural feeding habits (e.g. rooting in pigs). A considerable proportion of the behavioural effects of dietary fibre are thought to be related to reduced feeding motivation. It has been hypothesized that: (1) bulky fibres increase satiety and thereby decrease physical activity and stereotypic behaviours immediately following a meal in pigs; (2) fermentable fibres prolong postprandial satiety and thereby reduce physical activity and appetitive behaviours for many hours after a meal. The validity of these hypotheses is examined by considering published data. In sows dietary fibres (irrespective of source) reduce stereotypic self-directed behaviours and substrate-directed behaviours, and to a lesser extent overall physical activity, indicating enhanced satiety shortly after a meal. Furthermore, fermentable dietary fibre reduces substrate-directed behaviour in sows and physical activity in sows and growing pigs for many hours after a meal. Evidence of long-term effects of poorly-fermentable fibre sources is inconclusive. The findings suggest that highly-fermentable dietary fibres have a higher potential to prolong postprandial satiety.Non-starch polysaccharides: Fermentation: Fibre bulkiness: Physical activity

“…Besides, Thodberg et al (2002) suggested that a greater nervousness of the parturient sow could be associated to a longer duration of parturition but also to a shorter birth interval between the first-and the third-born piglets. As a consequence of the alleviating effects of a fibrous diet shown by Brouns et al (1994) on the sow activity, it could be hypothesised that sows fed a fibrous diet during gestation would show less nervousness and consequently have shorter parturition durations. Nevertheless, we did not find such significant effect on the birth interval between the first and the third-born piglets and on the duration of parturition, which could be related to high variation between experimental sows for these criteria (min.-max.…”

In pig production, parturition progress is a key event for sow's reproductive performance, evaluated by piglet survival and piglets' performance. The aim of this study was to investigate the impact of feeding a high-fibre (HF) diet during gestation on parturition progress and reproductive performance of sows. Forty-two primiparous sows (Large-White 3 Landrace crossbred) were fed during gestation either a control diet (C diet; 2.40 kg/day, 3.2% crude fibre, in % of dry matter (DM)), or a HF diet (2.80 kg/day, 12.4% crude fibre, in % of DM). All sows received 33 MJ digestible energy per day. Continuous video recordings were done on the parturition day to determine postural changes (standing, sitting, lying) and behavioural activities (nesting behaviour, uterine contractions, restlessness, social behaviour towards piglets) during parturition. Duration of parturition and individual birth intervals were also measured. Piglets' growth was evaluated by weekly weighing from birth until weaning, at 26.5 days of age. Sows were weighed and backfat thickness was measured at mating, on day 105 of gestation, on the 1st day post partum, and at weaning. Durations of parturition and of birth intervals were not affected by the gestation diet and averaged 211 6 12 min and 16.5 6 0.9 min (mean 6 s.e.), respectively. During the parturition progress, the gestation diet did not affect the frequency and the time devoted to postural and behavioural activities. Dietary treatment during gestation did not influence duration of gestation and weaning-to-oestrus interval, as well as litter size, and number of stillborn and weaned piglets. Piglet weight at birth did not differ between gestation dietary treatments but piglets nursed by HF sows showed a 13.5% greater growth rate during the 1st week of life (P , 0.01) and tended to be heavier at weaning (P 5 0.06) compared with C piglets. The HF sows were leaner at the end of gestation (P , 0.05), but variations of sows' weight during gestation and lactation were not affected by the gestation diet. All sows lost the same amount of backfat thickness during lactation. During lactation, the average daily feed intake was not significantly affected by the gestation diet. This study shows that substituting a control diet for a HF diet during gestation has limited effects on farrowing progress and reproductive performance, but improved piglets' growth rate during the 1st week of life and tended to increase their live weight at weaning.

“…promote satiety); 7) feeding at irregular time intervals (i.e. decrease the predictability of feeding times); or a combination of two or more of the aforementioned options (Shepherdson et al, 1993;Brouns et al, 1994;Young et al, 1994;Newberry, 1995;Bauck, 1998;Aerni et al, 2000;Young, 2003;Hernandez-Divers, 2006;Honess and Marin, 2006;van Krimpen et al, 2009). The applicability of the various approaches, however, may vary across species, depending on species-specific characteristics such as the animals' intelligence, natural diet, methods of food procurement and foraging pattern.…”

a b s t r a c tForaging enrichment is considered one of the most effective strategies to improve welfare and reduce stereotypies and other abnormal repetitive behaviours in captive animals, including parrots. Few studies, however, have investigated the effects of the different types of enrichment and determined their effect on increasing foraging times and foraging-related activities.To study the effect of different types of enrichment on foraging activity, eleven types of foraging enrichment [multiple bowls, mixing food with inedible items, larger-sized food particles, and 8 puzzle feeders] were tested in 12 Grey parrots (Psittacus erithacus erithacus). After acclimatization and assessment of baseline foraging times, enrichments were presented in a random order. Video recordings were used to analyze total foraging times and times spent on the different foraging activities. In addition, the frequencies and duration of foraging bouts, and the times at which they occurred, were determined. The learning curves and presence of habituation to the enrichment over a 1-week period were also assessed.Parrots needed 8.3 ± 1.1 days to learn how to use the foraging enrichments. For two of the puzzle feeders, it took considerably longer. Nine out of eleven foraging enrichments were able to significantly increase foraging times, with the most effective enrichments resulting in a 2-to 2.5-fold increase compared to baseline values (47 ± 18 min). The increases in time spent on foraging could be attributed to an increased amount of time spent on enrichmentrelated activities and/or an increased amount of time spent on food-related activities. None of the enrichments (including the use of multiple bowls in different locations) resulted in significant increases in time spent on locomotory behaviours (i.e. movement towards or away from the feeding site). No significant downwards trends in foraging times were observed over the 1-week observation period. The duration of the observations may, however, have been too short to demonstrate habituation effects.Results of this study show that distinct differences are present in the difficulty level, efficacy and time allocation, thereby affecting the choice for a particular foraging enrichment. Although most of the foraging enrichments were able to significantly increase foraging time, none of the enrichments were able to increase foraging times to levels comparable with that of wild conspecifics (i.e. 4-6 hours per day). New, more effective types of foraging enrichment should therefore be developed and tested.
