“…A similar result was obtained by Gidenne and Perez [12] and by Maertens [20], and it might be attributed to a weak appetency possibly because of the very small particle size provided by the extrusion process. It should not be due to the digestible energy content of this diet, since in the young rabbit the feed intake is not dependent on the dietary digestible energy level [10].…”

-Four high-starch diets (20%) varying only by the source of starch (wheat = diet W; barley = diet B; maize = diet M; extruded maize = diet EM) were given ad libitum before weaning (at 29 d old) from 18 days of age, to 8 litters (2 litters per diet) of 8 rabbits caged separately from their mother. Starch concentration in the ileal digesta and caecal fermentative characteristics were assessed at weaning and at 50 d of age, while faecal digestibility was measured between 46 and 50 d of age. The energy digestibility coefficient was the highest for the barley based diet while the lowest were observed for wheat and maize based diets (P < 0.05). At weaning, the level of starch in the ileum was high and similar for W, B and M diets (meanly: 8.8% DM), but was 5 points lower for the EM diet. At 7 weeks of age, it remained high (>10% DM) with the maize based diet, while it decreased for the other groups (less than 6% DM). The faecal digestibility of the glucidic fraction (NNCC) was almost complete (> 92%) and significantly higher with the EM diet followed by the B diet. NNCC digestibility was negatively correlated with ileal starch concentration (r = -0.63, P < 0.001). The fibre and protein digestibility remained unaffected by the dietary treatment, and no significant correlation was detected between the ileal starch level and fibre digestibility (NDF or ADF). Caecal VFA concentration increased by 11 mmol (+20%) from weaning to 7 weeks of age, while ammonia level decreased by 15%. Compared to weaning, at 7 weeks of age, the butyrate proportions were 5 units higher. The starch source did not significantly affect the caecal traits or fermentations, except for a slight increase in the empty caecal weight for EM and B compared to the W and M diets (P < 0.05). The ileal starch concentration was not correlated with caecal fermentative activity. rabbit / digestion / starch nature / extrusion / caecal fermentation Résumé -Effet du type de céréale et de l'extrusion dans l'alimentation du lapin en croissance.

Dietary fibres in the nutrition of the growing rabbit and recommendations to preserve digestive health: a review

The importance of dietary fibre fractions in animal feeding is due to its influence on the rate of passage, mucosal functionality and its role as substrate for gut microbiota that relates to performance and digestive health. The complexity of the physical structure and chemical composition of polysaccharides in plant cell walls explains the wide and different physiological effects of this large range of fibre fractions. Our review will first briefly consider the definition and structure of the different classes of fibres and of cell wall constituents, followed by a description of some analytical methods employed for monogastric feeds. Second, the nutritional role and impact of fibre intake on digestive health will be described for the growing rabbit with an extensive analysis of previous studies performed without antibiotics. The fibres in rabbit feed are essential for reducing the risk of digestive trouble after weaning, and the requirements are defined in terms of the quantity and quality of the fibre fractions as follows: a minimal dietary level of lignocellulose 'ADF' (18%) and lignins (>5%), balanced with a maximum quantity of digestible fibres 'DgF' (ratio DgF/ADF below 1.3). Soluble fibres, defined as the difference between total dietary fibre and NDF, are quickly fermented and digested by the rabbit. However, their impact on digestive health is still questioned.Keywords: dietary fibres, definition, nutrition, digestive health, rabbit Implications Post-weaning mortality from digestive troubles still remains a key problem in conventional breeding of rabbits. Dietary fibres recover more than 50% of feed for the growing rabbit. New criteria for fibre analysis in feeds were developed, and were related in several recent studies with the digestive physiology of rabbits and risk of digestive troubles. The present review aims to summarise these results through an extensive analysis of the literature. We also propose practical recommendation for fibre requirements in the feed of the growing rabbit to preserve the digestive health. IntroductionThe concepts on dietary fibres historically differ in animal feeding from those developed in human nutrition. For the latter, this is a rather modern concept, mainly developed in the 1960s (Hippsley, 1953) in order to deal with several pathologies (colorectal cancer, obesity, etc.), regularly revisited (Trowell, 1978;De Vries, 1999;Elleuch et al., 2011) and often restricted to the polysaccharides of the plant cell wall of fruits and legumes. In contrast, animal nutritionists deal with other 'less-refined' fibre sources, often from whole plants (forages, by-products of seed processing, etc.), and recover a larger range of chemical components, including other polymers such as polyphenolic (lignins, tannins) or polylipidic compounds (cutins).At present, these two conceptions are converging, and dietary fibres are generally defined as polysaccharides and associated substances resistant to mammal enzyme digestion and absorption that can be partially or totally fermented in the gu...

“…On the contrary, other studies suggested that the regulation of the solid feed intake in young rabbits would implicate other mechanisms than the level of the digestible energy. Thus, young rabbits fed a 'high energy/ high starch' diet ingested more solid feed, with an equivalent amount of milk ingestion (Fortun-Lamothe et al, 2001) or furthermore with a higher milk intake (Debray et al, 2002;Gidenne et al, 2007). In our study, weaned rabbits ate 20% less digestible protein than suckling rabbits between 23 and 27 days of age.…”

The ability of young rabbits to digest a solid diet was evaluated according to the weaning age: 21 (W21, 12 litters) or 35 (W35, 12 litters) days of age. From 14 days onwards, the rabbits were fed the same pelleted feed. Three methods were compared to estimate the faecal digestibility in the young rabbits, between 24 to 28 and 38 to 42 days. Digestive balance at ileal and faecal levels was determined for the main nutrients provided by milk and solid feed. The W21 rabbits increased their solid feed intake only 2 days after their weaning, when compared with suckling rabbits. Thus, their crude protein (CP) intake remained lower until 26 days compared with the W35 rabbits (from 41%, P , 0.01), as well as their crude fat intake until 28 days (from 72%, P , 0.001). On the contrary, the W35 rabbits increased their solid feed intake without a delay after weaning, quickly reaching the intake level of the W21 rabbits. The amounts of organic matter (OM) and CP reaching the caecum were increased on day 28 by 56% and 42% in the W21 rabbits compared with the W35 rabbits, respectively (P , 0.05), and were similar between groups on day 42. Starch ileal digestibility coefficients were 94 Á 2% and 95 Á 4% in 28-and 42-day-old rabbits, respectively, irrespective of the weaning age. The amount of starch flowing through the ileo-caecal junction was low and only tended to be higher on day 28 in the W21 group (0.20 v. 0.15 g/day in the W35 group, P 5 0.10). The digestive balance pointed out that the digestible energy intake was similar between weaned and suckling rabbits from 23 to 27 days, a phenomenon partly explained by a high ability of the W21 rabbits to digest starch (98%) and NDF (36%). Indeed, the amounts of starch and NDF digested by the W21 group were 2.0-and 2.4-fold higher than those of the W35 rabbits at this period (P , 0.001). However, they ate 20% less digestible proteins than still-suckling rabbits (P , 0.001). From 38 till 42 days, only a lower ability of the W21 rabbits to digest lipids was detected (P , 0.05). In conclusion, early-weaned rabbits were able to adapt quickly to digest large amounts of starch and fibres.
