“…However, Pinheiro and Gidenne [13] found a higher morbidity for diets containing 14% of crude potato starch (resistant to digestion), but the ileal starch level was only 1.3% in 6 wk old rabbits. At the end of rabbit fattening, the mortality was generally lower and was supposed to be related to the low starch ileal flow (<2 g·d -1 ) observed at this age, even with a high starch/low fibre diet [8]. Nevertheless, no relationship was found here between mortality and ileal starch concentration.…”

“…The flow of nutrients reaching the caecum modifies the balance of the caecal ecosystem [1], and thus may alter the sensibility of the animals to enteropathy. Dietary fibre constitutes the main part of the nutrient ilea flow, and thus plays a key role in this enteropathy syndrome [8]. However, since the young rabbit incompletely digests starch till 7 weeks of age [5], a significant quantity of starch would reach the caecum and may interact with digestive health, particularly for starch sources resistant to digestion in the small intestine such as maize.…”

-The effects of the quality of the dietary starch on growth performance and mortality were studied on five experimental sites on 1784 growing rabbits (446 per diet). Four iso-fibre diets varying in starch nature (W-wheat, B-barley, M-maize, EM-Extruded maize) were compared. The diets were given ad libitum from weaning (30 to 35 d. of age, depending on the site) to slaughter (68 to 71 d). From weaning to 49 days of age, the weight gain did not differ significantly according to the starch source (mean = 48.6 g·d -1 on average). The feed intake was higher for the M diet compared to the other three diets (+5%, P < 0.01). During the finishing period (49 d to slaughter), the weight gain was significantly higher for the EM diet compared to the W or B diets (+2%). The feed consumption was 5% higher (P < 0.01) for the M diet, compared to other treatments. Thus, feed conversion was the worst for the M diet, while it was the lowest for the EM diet. During the whole fattening period, the weight gain was only slightly higher with extruded maize feed, compared to the others (meanly +0.8 g·d -1 ). Correlatively, feed intake and conversion index were significantly lower for the EM diet, while they were the highest for the M diet (-2 to -4% compared to B and W diets). On the five experimental sites, mortality was always caused by acute digestive disorders, without specific pathology. The mortality rate due to diarrhoea greatly varied among sites (between 1.7 and 19.4%). The mortality rate between weaning and 49 days of age and during the finishing period was not affected by the dietary starch origin. However, the mortality in the W group was 3 points lower than in the M group (P = 0.07). . Du sevrage à 49 jours d'âge, la vitesse de croissance a été élevée et n'a pas différé significativement entre les 4 traitements (en moyenne = 48.6 g·j -1 ). L'ingestion d'aliment a été plus élevée pour le régime M (+5 %, P < 0,01). En période de fin d'engraissement (49 j à abattage), la vitesse de croissance a été plus rapide pour le régime EM, comparée aux régimes "Blé" ou "Orge" (+2 %). L'aliment à base de maïs a présenté le niveau d'ingestion le plus élevé (+5 %, P < 0,01), et aussi l'indice de consommation le plus haut, tandis que le régime EM a présenté la conversion alimentaire la plus efficace. Durant la totalité de la période de croissance, la vitesse de croissance a été seulement légèrement plus élevée pour le groupe EM (en moyenne +0,8 g·j -1 par rapport aux trois autres groupes), tandis que l'ingestion et l'indice de consommation ont été les plus faibles (-2 à -4 % respectivement comparé aux groupes B et W). Sur les 5 sites expérimentaux la mortalité a toujours été causée par une diarrhée aiguë, sans pathologie spécifique identifiable. Le taux de mortalité par diarrhée a beaucoup varié selon le site (entre 1,7 et 19,4 %). La mortalité post-sevrage ou en fin de croissance ne varie pas significativement en fonction des traitements. Cependant, on peut remarquer un taux de mortalité inférieur de 3 points pour le groupe B par ra...

“…However, values obtained in the present study with 28-and 42-day-old rabbits were very high when compared with results reported in the literature for growing or adult rabbits. For instance, ileal digestibility of OM comprised between 56% and 66% in our study, whereas some authors reported values extending from 28% to 61% in older rabbits (Gidenne, 1992;Merino and Carabañ o, 1992;Gidenne et al, 2000). However, the variability of this measurement is often very high, and may explain part of these discrepancies (Blas et al, 2003).…”

“…We estimated by difference with faecal digestibility that only 7% to 8% of ingested OM would be digested in the large intestine. Values reported in the literature are included in growing or adult rabbits between 12% and 27% according to the fibre percentage in the diets (Gidenne, 1992;Merino and Carabañ o, 1992;Gidenne et al, 2000). A higher proportion of nutrient digested in the caeco-rectal compartment of older rabbits is relevant to the digestive maturation and the development of the microflora.…”

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.

“…These 60 rabbits were housed one animal per cage in the same environment and provided with food and water under the same conditions, and were unrelated within 3 generations. With a 7-day dietary transition, these rabbits were fed fibre-deficient diet (crude fibre[CF]=8.89%, in contrast to the standard diet of CF=15.16%, Table 1), which can induce NSDD in growing rabbit (Gidenne et al, 2000;Bennegadi et al, 2001). From the age of 49 d to 70 d, they were carefully observed twice a day with precise records for all clinical signs of NSDD, such as reduced feed intake, diarrhoea, constipation (caecal impaction) and presence of mucus in excreta.…”

Investigation of significant microRNA-mRNA pairs associated with nonspecific digestive disorder in rabbits

et al. 2017

Nonspecific digestive disorders (NSDD) are one of the major intestinal problems in rabbit, with considerable economic losses in industrial rabbit farms. MicroRNAs (miRNAs), as small non-coding RNAs, have significant biological involvement in intestinal disorders. In this study, we investigated the expression levels of 25 genes and 25 miRNAs in ileum, rabbit sacculus rotundus (RSR) and colon tissues from 9 rabbits with different severity of NSDD. These molecules have been found to be related to NSDD or inflammatory bowel disease, which will help recognise the miRNA-mRNA pairs. Finally, 108 possible pairs of miRNAmRNA pairs with an anti-correlation were identified by Pearson's correlation analysis between differentially expressed 25 miRNAs and 23 mRNAs. Ninety-five of these miRNA-mRNA pairs were hitherto unexplored, and their roles in NSDD biology require further elucidation. Our results give a clue to the potential miRNAmRNA pairs for the NSDD that can further improve the understanding of the pathogenesis of NSDD in rabbit.
