“…In the high NDSF diets, this effect of dietary ADF was larger, which could be explained by a differentiated transit, faster for liquid than for solid phase, associated to stimulated caecal rate of passage. Faster oro-rectal rate of passage of fine particles (and not of large ones) has been reported as a result of increasing the dietary lignin content (Gidenne and Perez, 1994). Similarly, Gidenne and Perez (2000) and Gidenne and Jehl (1996) found faster oro-rectal rate of passage of liquid phase and fine particles (and not of large ones) or faster ileo-rectal rate of passage of liquid phase (and not of solids), respectively, when increasing the dietary fibre level (cellulose+insoluble hemicelluloses+pectins).…”

The effects of the composition of peri-weaning diets on apparent ileal digestibility of nutrients and caecal environment were studied in growing rabbits. Eight diets were formulated according to a 2x2x2 factorial design to increase acid detergent fibre ( ; P<0.001) and reduced caecal pH (-0.10; P<0.05). In the low NDSF diets, higher ADF increased DM content of caecal digesta to a lesser extent (+16 g kg Overall, the three dietary changes under study led to changes in the caecal environment which might be effective in reducing mortality rate in a context of rabbit epizootic enteropathy.

“…Since the grape pomace has a high concentration in lignin (Table 1), the dietary NDF and ADL level increased sharply with GP incorporation (Table 2), and could explain the negative effect on digestive efficiency for DM, OM or energy (Table 4, Gidenne and Perez, 1994). However, the negative effect of GP on protein and energy digestion appeared significant only for a 6% incorporation rate.…”

ABSTRACT:The nutritive value and potential use of sun-dried grape pomace (g/kg as fed: 140 of crude protein (CP), 529 of neutral detergent fi bre (NDF), 460 acid detergent fi bre, 293 acid detergent lignin) for fattening rabbits was studied by comparing 3 experimental diets containing a low but increasing incorporation rate of grape pomace (GP): 0% (control, GP0), 3% (GP3), and 6% (GP6) in substitution to the control diet (251 g NDF and 175 g CP/kg) formulated with raw materials available in the area of Tiaret (Algeria): barley, wheat bran and straw, soybean meal and faba bean. Three groups of 30 rabbits (individually caged) were fed ad libitum the three diets from weaning (35 d, mean weight 460±83 g) to 77 d of age. The dry matter digestibility was obtained from total and individual faecal collection on all animals (3 x 30), during four consecutive days each week from 42 to 77 d of age. Then, faeces from 10 rabbits per group were selected for nutrient analyses. Intake and weight gain were recorded twice a week during the whole fattening period. Incorporating 3 or 6% of GP in a low fi bre diet impaired from 35 to 77 d growth rate P<0.01), feed conversion (+8.5% for GP6 vs. GP0, P<0.01), and dressing out percentage (-2.5% for GP3 and GP6 vs. GP0, P<0.001). The digestibility of organic matter was linearly reduced from 72.8 to 70.0% with the GP incorporation rate (P<0.01), while crude protein digestibility remained unaffected and averaged 78.7%. The predicted nutritive value of sun-dried GP calculated by regression was high but highly variable for digestible energy (9.33±2.01 MJ DE/Kg, raw basis), and particularly for the digestible protein content (81.8±77.2 g DCP/kg). Thus, the sun-dried whole grape pomace could be considered as an alternative fi bre source for the rabbit feeding in Magrebian area.

“…The minimum transit time (TTm) is the delay time (average time between two collects) for the first appearance of the marker in the faeces, which is equivalent to the passage time in the small intestine and the distal colon of the rabbit [17]. Moreover, caecotrophy causes to inflect the decrease of the faecal concentration (Ct) of the marker of the solid phase [19], because of a recycling of labelled particles in soft faeces. We thus carried out a double adjustment of the decreasing part of the kinetics before and after caecotrophy, using a non-linear regression according to an exponential (Ct = Co .…”

-The effects of digestible fibre replacement (25 to 15%) by starch (12 to 23%), were studied on rabbit digestion with four diets (A12 to A24) having a similar level of lignocellulose (ADF, 18%). Faecal digestibility, retention of nutrients and rate of passage were measured on four groups of 12 young rabbits fed the four diets ad libitum from weaning to slaughter (72 d). Intake, weight gain, and feed conversion were not significantly different among the 4 treatments (mean 102.4 g . d -1 , 34.0 g . d -1 , 3.02 respectively). Despite a 100% increase in the starch level between A12 and A24, the digestibility of organic matter and energy were similar (mean 65.5 and 63.7% respectively). Energy or protein retention were not significantly affected by treatments (mean 28.4 and 13.6% respectively). With a reduction of the supply in digestible fibre, overall fibre digestibility (NDF) was logically reduced (-10 units), particularly for the uronic acid fractions (71 to 44% respectively for A12 and A24). Consequently the quantity of degraded NDF (period 28-72 d) decreased from 13.7 to 8.1 g . d -1 for the A12 to A24 diets, while it doubled for starch (12.5 vs. 23.1 g . d -1 ). Whole tract mean retention time for the particulate phase increased by 2 h ( P = 0.06) for the A12 to A24 diets, while it increased by 4 h ( P < 0.01) for the liquid phase. Caecal retention time of fine particles was more affected (+6 h) than that of large particles (+2 h). In conclusion, digestible fibre replacement by starch did not change the digestive efficiency of the rabbit, but slowered the passage rate. rabbit / digestion / passage rate / dietary fibre / starch / retention Résumé -Apports d'amidon en remplacement de fibres digestibles dans l'alimentation du lapin en croissance. I. Conséquences sur la digestion, le transit et la rétention des nutriments. En raison de ses conséquences importantes sur la digestion et la pathologie digestive du lapin, la lignocellulose (ADF) est un critère souvent utilisé pour recommander un apport de fibres. Cependant, les interactions entre l'amidon et les fibres « digestibles » (hémicelluloses et pectines) non prises en compte par le critère ADF ont été très peu étudiées.
