“…No significant effect of probiotic supplementation was observed on carcass traits (Table 4). Rabbits in all dietary groups had similar dressing yield (average 58%), which corroborate well with the earlier reported values Rotolo et al 2014). Besides, a measure of caecum weight and the epithelial layer thickness were assessed, which revealed relatively higher weight and a significantly increased thickness in both the probiotics-supplemented groups than the control.…”

“…Some authors reported that probiotics can influence GI weight and the relative proportion of its organs and also the microbial fermentation pattern in the ceacum . Rotolo et al (2014) observed similar caecum weight as percentage of total BW. Proliferation of colonocytes in response to prebiotic effects of hemicelluloses and colonization of supplemental probiotics might have contributed to thickening of mucosa without hindering the nutrient absorption process.…”

Forty-five weaner Chinchilla rabbits (42-d-old, average weight 619 g) randomly assigned to three equal treatments, control with no probiotic and the other two with probiotics (10 7 CFU/g concentrate) Lactobacillus acidophilus and Lactococcus lactis. They were reared in individual cages and fed on ad libitum concentrate and wilted Lucerne (Medicago sativa) up to 91 d of age. Compared to control L. acidophilus improved weight gain (24.5 vs. 22.5 g/d, P < .05), whereas it was intermediate with L. lactis. Both probiotics improved the feed conversion ratio (3.91 and 3.96 vs. 4.34, P < .05) but no effect on dry matter intake (95.8 and 92.7 vs. 98.0 g). Dry matter and organic matter digestibility improved with L. acidophilus (72.8 vs. 67.0%, P < .05), whereas it was intermediate with L. lactis. Probiotics also improved (P < .05) digestibility of crude protein (82.7 vs. 74.9%) and neutral detergent fibre (41.9 vs. 29.4%). Nitrogen utilization improved with reduced faecal excretion in probioticssupplemented groups. Probiotics had non-significant effect on carcass traits and fatty acid profile (P > .05). Thus L. acidophilus supplementation enhanced digestibility and utilization of nutrients, weight gain and feed conversion ratio with no negative effect on carcass traits and fatty acid profile.

“…Kimsé et al (2012) and Rotolo et al (2014) did not report any effect of live yeast (Saccharomyces cerevisiae) on volatile fatty acid molar proportions. Furthermore, Maertens et al (1994) and Bonai et al (2008) did not note any effect of Bacillus on the fermentation pattern.…”

“…The counts of coliforms and total aerobic bacteria in caecum were low. Related to the effect of yeast supplementation on slaughter traits, Rotolo et al (2014) reported no effect on the weight of the full and empty caecum. However, Maertens et al (1994) observed that caecal weight was higher in rabbits fed the Paciflor ® (Bacillus) diet.…”

Effect of diet supplementation with live yeast Saccharomyces cerevisiae on growth performance, caecal ecosystem and health of growing rabbits

et al. 2016

The aim of this study was to determine the effect of the live yeast Saccharomyces cerevisiae on the growth performance, caecal ecosystem and overall health of growing rabbits. A control diet was formulated (crude protein: 15.9%; neutral detergent fibre: 31.6%) and another diet obtained by supplementing the control diet with 1 g of Saccharomyces cerevisiae (6.5×10 9 colony-forming units) per kg of diet. Ninety 35-d old rabbits were allotted into 3 groups: TT (rabbits offered the supplemented diet from 17 d of age onwards), CT (rabbits offered supplemented diet from 35 d) and CC (rabbits fed non-supplemented diet). Body weight (BW) and feed intake were measured weekly and mortality was controlled daily. At 35, 42 and 77 d of age, 6 rabbits from each group were slaughtered and digestive physiological traits, serum clinical chemistry parameters, fermentation traits, and the composition of caecal microbiota examined. At 42 and 56 d of age, 10 rabbits from each group were injected intraperitoneally with 100 µg/animal of ovalbumin and blood samples were collected for examination of plasma immunological parameters. Throughout the experiment (5-11 wk), weight gain and feed intake (37.8 and 112.6 g/d, on av.) were not affected by yeast, except for weight gain in the first week after weaning, which was the highest in TT animals among the 3 groups (48.1 vs. 43.9 and 44.2 g/d for TT, CC and CT, respectively; P=0.012). This may be due to the increased trend in feed intake (P=0.072) in the TT group (96.4 g/d) compared to the others. Mortality (5/90) was low and did not differ among the 3 groups. Treatments had no effect on slaughter traits at the 3 sampling dates (35, 42 and 77 d). Only the weight of the empty caecum (% BW) was higher (P=0.02) in CC (2.2%) and CT (2.3%) than in TT group (1.8%) at 77 d of age. Treatments did not overtly affect the caecal microbiota, although the number of total anaerobic bacteria and Bacteroides were lower (10 8 and 10 7 /g caecal digesta, respectively) in rabbits from CC group compared to those of CT and TT groups at 42 d of age (P=0.03). No difference between groups was observed for caecal short chain fatty acids profile, blood traits, or IgG and cytokine profile. In conclusion, supplementation of feed with yeast did not modify growth traits and resulted in only a temporary increase in weight gain and a slightly altered caecal microbiota after weaning.

“…Supplementation with alternative substances, such as probiotics, prebiotics, enzymes and organic acids, has been studied in rabbits, with interesting results emerging (Falcão-e-Cunha et al, 2007;Rotolo et al, 2014). However, the number of phyto-studies remains limited (Botsoglou et al, 2004;Krieg et al, 2009;Arafa et al, 2010;Simonová et al, 2010;Ayala et al, 2011;Szabóová et al, 2012;Rotolo et al, 2013).…”

In this study, 160 Hycole weaned rabbits (35 days old) were randomly divided into four groups of 40. The rabbits were studied throughout a 54-day experimentation period in order to determine the impact of dietary supplementation from herbs composed of 0.2%, 0.4% dry ground Lythrum salicaria leaves (LS) and 0.3% Cunirel ® (CR; a commercial herb mixture containing LS as the main ingredient) on performance, digestibility, health and meat quality. The basal diet was given to the control group. No significant differences were found in performance, 10 rabbits from each group were selected for evaluation regarding apparent digestibility. The rabbits fed the control diet and the diet with the low level of LS had a higher level of CP digestibility than did the animals that were supplemented with the high LS levels and CR (85.7% and 84.9% v. 84.0% and 84.0%, respectively; P < 0.05). The ether extract digestibility was lower in the treatment group with 0.4%LS addition and CR as compared with the control group (52.2% and 54.5% v. 62.6%, respectively; P < 0.05). The slaughter process was performed on 89-day-old rabbits to study the carcass characteristics, meat quality, blood parameters, caecal contents and gut histology. The total leukocyte counts in the control animals were lower than they were in the rabbits fed 0.2%, 0.4%LS and CR (4.06 v. 8.25, 8.63 and 8.21 × 10 9 /l, respectively; P < 0.05). For caecal fermentation, the caecal contents of the rabbits fed 0.4% of LS, showed higher concentrations of total volatile fatty acid (VFA; 24.1 v. 18.9 mg/kg dry matter (DM); P < 0.05) and acetic acid (18.3 v. 14.4 mg/kg DM; P < 0.05), but lower ammonia levels (594 v. 892 mg/kg DM; P < 0.05) as compared with the control group. PCR-denaturing gradient gel electrophoresis analyses were performed to evaluate the microbial community in hard faeces, collected at days 35, 42, 49, 56, 70 and 89, whereas the caecal contents were taken after slaughtering. The results demonstrated that between the treatment groups, the similarity of the microbial communities was higher as compared with the control group. Moreover, only age was shown to influence microbiota diversity. In conclusion, the results of this study indicated that supplementation of LS in rabbit diets leads to an increase in the total white blood cells, total VFA and acetic acid concentration, and a decrease in the ammonia levels, as well as the digestibility when CR and high level of LS were supplemented, without causing any adverse effects on other parameters.
