“…A significantly lower digestibility coefficient of cellulose was observed in rabbits fed the diet supplemented with MOS. Similarly, a significantly lower digestibility coefficient of crude fibre was observed in the growing pigs fed a diet with MOS in comparison with control pigs (Lipiń ski et al, 2005). In our study, lower digestibility of cellulose can be explained by lower cellulolytic activity observed in the caecum of these rabbits (Table 5).…”

The effect of a dietary supplementation with mannan-oligosaccharide (MOS, Bio-Mos, Alltech Inc.) and inulin (Frutafit w IQ) on growth, health, and caecal traits was studied on 348 rabbits (Hyplus w ), weaned at 25 days of age. Three hundred and thirty rabbits (110 per group) were used for the health status and growth performance trial, while 18 rabbits (six per group) were used for caecal metabolism evaluation at the age of 42 days of age. Three diets were formulated: C (control), M (0.3% MOS) and I diet (4% inulin). Digestibility of the diets was measured in 10 rabbits per group between 36 and 40 days of age. The control diet was fed to rabbits of the C group from weaning to 74 days of age (slaughter). Diets M and I were fed to rabbits of the respective group from weaning to 46 days of age, then were fed with control diet till slaughter. From 25 to 46 days of age, the weight gain was slightly higher in control rabbits ( P ¼ 0.11), while no differences were recorded for the whole period. No differences among groups in the mortality, which was high due to an enteropathy-infected environment, were significant. The lowest morbidity ( P ¼ 0.05) as well as the health risk index were recorded in rabbits fed the diet with inulin ( P ¼ 0.03). After change of diet, the health risk index increased in the rabbits previously fed the diet with additives, thereby no significant differences in the health status were recorded for the whole period. Total caecal volatile fatty acids concentration was higher ( P , 0.01) and the pH ( P , 0.01) and ammonia concentration ( P ¼ 0.01) lower in rabbits fed the inulin diet than in other rabbits. In these animals, acetate molar proportion was higher ( P ¼ 0.01) and that of propionate as well as the propionate/butyrate ratio significantly lower than in other rabbits. Butyrate molar proportion was higher in rabbits fed the diet with MOS ( P , 0.01). In rabbits fed the inulin diet a higher activity of inulinase was recorded ( P , 0.001) than in other rabbits. A significantly lower digestibility of cellulose was observed in rabbits fed the diet with MOS. The results of our study suggest the importance of using inulin-type fructans in the nutrition of young rabbits. The higher health risk index of rabbits after change of diets indicates that prebiotics should be given for a longer time during the fattening period.

“…In fact, Trocino et al (2013b), in a meta-study on soluble fibre in rabbits, showed that an increase in dietary SF is positively correlated with an improvement in the digestibility of the remaining fibrous fractions. However, contrary to expectations, other studies have observed a lower cellulose digestibility in rabbits (Volek et al, 2007) and pigs (Lipinski et al, 2005) when mannan-oligosaccharides were included in the diet. On the other hand, although the faecal digestibility of NDF and ADF increased with the age of growing rabbits, no interaction with FSG inclusion was observed.…”

Preliminary evaluation of fenugreek (Trigonella foenum-graecum) seed gum as a potential prebiotic for growing rabbits in Tunisia: effects on in vivo faecal digestibility and in vitro fermentation

This study aims to determine the effect of dietary inclusion of fenugreek seed gum (FSG), rich in galactomannans, on nutrient apparent digestibility and caecal environment, as well as on in vitro caecal fermentation of Tunisian growing rabbits. Three experimental diets were formulated, including 0, 0.25 and 0.5% of FSG (FSG0, FSG0.25 and FSG0.5, respectively) for the in vivo trial and 0, 0.125, 0.25, 0.5 and 100% of FSG (FSG0, FSG0125, FSG0.25, FSG0.5 and FSG100, respectively) for the in vitro trial. In the in vivo trial, 45 weaned rabbits 31 d old (15 per treatment) were housed in individual cages until 94 d of age. Apparent digestibility coefficients were determined at two ages, from 38 to 41 and from 56 to 59 d old, and caecal traits were recorded after slaughtering. In the in vitro trial, the five experimental diets were incubated with a rabbit caecal inoculum. Gas production was measured and modelled until 72 h and the fermentation traits were measured. Apparent faecal digestibility coefficients of main nutrients and main caecal environment traits were not significantly affected by the dietary inclusion of FSG (P>0.05). However, animals fed with FSG showed lower caecal pH (–0.15; P<0.05) values. Regarding the in vitro fermentation, FSG100 increased asymptotic gas production (+11.25, P<0.001), sharpness of the switching characteristic of the profile (+1.98, P<0.001) and the maximum substrate degradation rate (RM) (+0.188, P<0.001), but decreasing the time after incubation at which half of the asymptotic amount of gas has been formed (–5.86, P<0.001) and at which RM occurs (–4.53, P<0.01). Likewise, FSG100 significantly decreased caecal pH (–1.035, P<0.001), lactic acid (–9.51, P<0.069) and N-NH3 concentrations (–12.81, P<0.001). Meanwhile, it increased the total volatile fatty acids (VFA) production (+43.15, P<0.001). Gradual dietary inclusion of FSG from 0 to 0.5% only significantly increased total VFA production in the caecum (+100 mmol/L per percentage point of FSG inclusion; P<0.05). In conclusion, FSG is highly and rapidly in vitro fermented by rabbit caecal bacteria. However, dietary inclusion of FSG up to 0.5%, might be insufficient to affect the apparent digestibility and fermentation profile of growing rabbits to a great extent.

“…Accordingly, Gómez-Conde et al (2007) and ( 2009) reported that increasing dietary SF content may stimulate the growth of fibrolytic microbiota in the gut, thus increasing the utilisation at both ileum and caecum of insoluble fibre fractions (hemicelluloses and ADF). However, other feed ingredients such as MOS reduced cellulose digestibility when added in rabbits and pigs' diet, explained by a lower cellulotic activity observed in the caecum of those animals (Lipinski et al, 2005;. However, all the fibre fractions were decreased by the gradual inclusion of FSG from 0 to 20 g/kg in the SF diet already even in the in vitro enzymatic pre-digestion, (-1.6, -1.1, -0.92 g/kg for NDF, ADF and cellulose respectively for each g/kg of FSG added).…”

This thesis tackles the possible characterisation and utilisation of fenugreek (Trigonella foenum-graecum) seed gum (FSG) in the nutrition of young rabbits during the post-weaning period as an alternative to antimicrobials uses. The study was focussed on the behaviour of the extracted gum with different dietary fibre levels, both in vitro and in vivo.In a first trial, starting from a basal commercial rabbit diet, three experimental diets were formulated with gradual levels of inclusion of FSG (0, 0.25, 0.50 %)given to three groups of rabbits starting from weaning at 31 days old to slaughter 94 days old. The effect of the experimental diets was studied on the faecal
