“…These results might suggest that rabbits given the SB diet have no gastrointestinal disorder (Gidenne et al, 2007), although no differences in mortality were reported between treatments. It is therefore possible that butyrate controlling the microbial population in the proximal part of the digestive tract consequently allows the development of beneficial bacteria in the distal part.…”

AbstrAct:To study the effect of adding coated sodium butyrate (SB) to growing-fattening rabbit diets, 2 trials were conducted. In trial 1, 180 rabbits were housed in pairs and fattened from 23 (weaning) to 63 d of age to evaluate their zootechnical performance. Trial 2 involved 30 rabbits, from 23 to 37 d of age and housed individually in digestibility cages, to evaluate digestibility, caecal fermentative activity and morphology of the intestinal mucosa. In both trials rabbits were randomly divided into 2 groups, each receiving one of the following diets: control diet [CTR, 360 g neutral detergent fibre (NDF) and 170 g crude protein (CP)/kg dry matter (DM)] and SB diet. The SB diet, similar to CTR diet, included coated SB at 5 g/kg by replacement of an identical quantity of wheat. In trial 1, after the first 2 wk, the SB content was reduced from 5 to 3 g/kg. In trial 2, faeces were collected over the last 6 d (32-37 d of age), with rabbits being slaughtered at 37 d of age. Gastric and caecal pH were measured and fermentative activity was determined in caecal contents. Three sections of the small intestine were excised from 20 rabbits (10 per treatment) for microscopic examination of intestinal villi and crypts in the proximal region, central region and distal region. In the first 2 wk after weaning, SB rabbits grew 8% less than their counterparts (P=0.002), but had a better feed conversion ratio (1.58 vs. 1.61; P=0.036). During the whole trial 1 period, SB improved feed conversion (P=0.005) and decreased feed intake (104.1 CTR vs. 98.8 g/d SB; P=0.017). No difference was recorded in daily weight gain (42.7 vs. 42.9 g/d). In both diets, the digestibility of DM, organic matter, energy, CP and NDF were similar. In the 3 intestinal regions of rabbits fed SB diet, crypts were deeper (P<0.05). There were no significant differences in villus height and width between treatments. Pectinase activity was higher (P=0.054) with SB diet, but cellulase and xylanase activity remained unaffected by diet. In our experimental conditions, the addition of SB allowed an improvement in feed conversion.

“…This effect was independent of the previous milk intake, when it was included as a covariate in the model. Gidenne et al (2007) also found that litters eating the lowest NDF/starch ratio showed the highest feed intake from 25 days to weaning (32 days), in spite of their higher milk intake in this period. It suggests that feed and DE intake in this period might not be entirely explained by changes in dietary DE concentration, but by other factors (as the bulk of the diet and/ or the source of fibre) that might play a more important role in its regulation.…”

“…We found a lower amylase activity in the intestinal content of the young rabbits having a high starch intake (W21) at 28 days of age, which is not in agreement with the results of Gutié rrez et al (2002) who showed a higher production of pancreatic amylase in early-weaned 35-day-old rabbits, and thus having a higher feed (and starch) intake than still-suckling rabbits. Gidenne et al (2007) also found that the global intestinal amylase activity was lower for young rabbits having a high starch intake. ; n 5 7 to 12 according to the age and the weaning age.…”

The functional adaptability of the digestive system to the level of feed intake was investigated in the young rabbits by comparing two groups of 12 litters each, weaned at 21 (W21) or 35 (W35) days of age. From 14 days onwards, rabbits were fed a pelleted feed (NDF: 332 g/kg, CP: 177 g/kg, starch: 98 g/kg, as-fed basis). Until 49 days of age, the profile of digestive enzymes was weekly determined in the small intestinal content and mucosa, as well as caecal fermentation traits and fibrolytic activities. In the W21 group, the solid feed intake was increased by 57% between 21 and 35 days (P , 0.01), while the daily body growth was lower from 21 till 42 days (217%, P , 0.05) when compared with the W35 group. Activities of enzymes of pancreatic origin were only scarcely influenced by the weaning age. In the W21 group, amylase activity tended to be lower at 28 days of age (236%, P 5 0.064), and trypsin activity was decreased by 31% at 49 days of age (P , 0.01). Lipase activity was similar in both weaning groups. Duodenal and jejunal activities of maltase and aminopeptidase N (APN) were higher on day 28 in the W21 group as compared with the W35 group (31.4 to 32.4, respectively, P , 0.05). On day 35, duodenal APN activity was twice as higher in the W21 group than in the W35 group (P , 0.01). In caecum, major differences between both weaning groups were observed at 28 days of age with a decrease in ammonia concentration (243%, P , 0.01) in W21 compared with W35 rabbits. Conversely, the acetate proportion was 5% higher in the W21 group (P , 0.01) on day 28. In conclusion, the digestive tract of early-weaned rabbits showed some adaptative properties in response to nutritional environment changes, but they were insufficient to maintain their growth rate.
