“…This effect could be ascribed to the prebiotic effects of chitin that can increase the production of butyric volatile fatty acid in caeca (Khempaka et al, 2011;Bovera et al, 2016). Butyric acid is considered the prime enterocytes energy source (Bovera et al, 2010) and it is also necessary for the suitable development of the gut-associated lymphoid tissue (Mroz, 2005). It is documented that butyrate is the major intestinal energy source even when other fuel sources (glucose or glutamine) are available and could stimulate the growth of colorectal and ileal mucosal cells (Montagne et al, 2003;Topping and Clifton, 2001).…”

The aim of this study was to evaluate the effects of the inclusion of Tenebrio molitor larvae meal in practical diets for gilthead sea bream on growth performance, nutrients digestibility, somatic and marketable indexes. Two separate trials were carried out: in the first a total of 153 gilthead sea bream (105.2 ± 0.17 g average initial body weight) were randomly allocated in 9 fiberglass 220 liter tanks (17 fish per tank) in an indoor water recirculating system. The fish were fed three isoenergetic and isoproteic diets formulated to contain increasing levels of TM meal inclusion and precisely: a control diet (TM0), in which fish meal was the main protein source; TM25 and TM50 diets, in which 25% and 50% of Tenebrio molitor larvae meal was added to the diet, respectively. These inclusion rates corresponded to 30% and 60% of inclusion on protein bases and 35% and 71% of fish meal substitution on protein bases for TM25 and TM50 diets, respectively. Each diet was randomly assigned to 3 tanks and the trial lasted 163 days. In the second trial the apparent digestibility coefficients of the 3 diets were measured on 72 fish randomly distributed to 3 digestibility tank-units (24 fish per unit, average body weight: 86.97±2.3 g) using an indirect method (acid insoluble ash).The group fed TM25 showed a higher (P < 0.05) final weight, specific growth rate, weight gain %, protein efficiency ratio, and a lower feed conversion ratio compared to the other 2 groups. The estimated apparent digestibility coefficients of crude protein and ether extract of the diets were lower (P < 0.01) in TM50 than in the other 2 groups. No significant differences have been found between TM0 and Tenebrio molitor larvae meal groups in morphometric and commodity-related characteristics, except for dressed yield and viscerosomatic index (VSI), that resulted the lowest and the highest, respectively, in TM50. The skin colour resulted to be affected by dietary inclusion of insect meal, especially at 50% of inclusion. The general evaluation of the results demonstrates that Tenebrio molitor larvae meal can replace fish meal up to 25% of inclusion in the diet for Sparus aurata without negative effects on weight gain, crude protein and ether extract digestibility, marketable indexes after 163 days feeding. On the contrary, when Tenebrio molitor larvae meal was included at 50%, nutrient digestibility, dressed yield, VSI and skin colour were penalized.

“…In the literature, MOS was reported to improve the performance and immunity of animals (Rosen 2007;Bovera et al 2010;Attia et al 2014a,b). The manner of action of MOS could be attributed to enhancing the nutrient digestibility, and improving gastrointestinal beneficial microbiota and the intestinal morphology (Hooge 2004;Hooge & Connolly 2011).…”

This study aims to utilise thyme oil (TO) as a natural growth promoter in comparison to mannanoligosaccharides (MOS) for broilers raised under hot climates from 1 to 28 days of age. Thus, a total of 180, day-old broilers chicks were divided into five groups (36 broilers/group in 6 replicates of 6 broilers/replicate). The chickens were fed the same corn-soybean meal basal diet and were submitted to one of the following five dietary treatments: (a) positive control group, fed the basal diet supplemented with MOS at 1g/kg feed; (b) negative control group, fed the basal diet without supplementation; (c) thyme oil 1.0 (TO_1.0) group fed TO at 1.0 g/kg feed, (d) thyme oil 1.5 (TO_1.5) group fed TO at 1.5 g/kg feed and (e) thyme oil 2.0 (TO_2.0) group fed TO at 2.0 g/kg feed. The TO_1.0 displayed a better feed conversion ratio (FCR) than did the other treatments (p < .01). The MOS, TO_1.5 and TO_2.0 groups had higher (p < .01) plasma total protein than the control, and TO_1.5 also increased plasma globulin (p < .01) compared to the control, but decreased plasma albumin/globulin ratio. Moreover, the TO groups significantly decreased the plasma AST. Groups on the MOS and TO_1.0 diets showed higher (p < .01) white blood cells (WBCs) than the other groups. In addition, the MOS and TO_2.0 groups exhibited a greater (p < .01) antibody titre to infectious bursa disease (IBD) than the control group. In conclusion, TO at 1.0 g/kg diet may be used as a potential growth enhancer for broilers in hot region during 1-28 days.ARTICLE HISTORY

“…(2010a) found that, in comparison with antibiotics, the concentration of 1 g/kg of MOS induced an important reduction of mortality rate in rabbits under critical conditions involving an episode of Epizootic Rabbit Enteropathy. In vitro tests (Bovera et al., 2010b) also showed that MOS at 1.0 g/kg seems to have the best effect on microbial fermentations giving higher in vitro organic matter digestibility. However, in both studies, the conditions imposed by the farm made it impossible to use a control group fed without additives (antibiotics or mannan‐oligosaccharides).…”

To evaluate the effect of mannan-oligosaccharides (MOS) on in vivo performance, nutrient digestibility, fermentation characteristics and caecal microbial populations of rabbits, 144 thirty-five days old hybrid Hyla were equally divided into three groups, one of which was fed the same diet without additives (control group), one with antibiotics (colistin sulphate, 144 mg/kg; tylosin, 100 mg/kg; oxytetracyclin, 1000 mg/kg) and one with MOS (1 g/kg of diet). Mortality rate, live weight, feed intake and feed conversion ratio were recorded up to 62 days of age. At 60 days nutrient digestibility was measured by acid insoluble ash method. The caecal content of 10 rabbits per group was collected at 62 days and analysed for volatile fatty acids production, ammonia content and microbial count. Rabbits from the control group had a significantly (p < 0.01) lower body weight at 62 days (1638.9 g vs. 1779.4 g and 1862.5 g, respectively for the control, MOS and antibiotic groups) while the antibiotic group showed a higher (p < 0.05) feed intake than the control group (127.9 g/day vs. 109.3 g/day). Rabbits from the MOS group had a higher apparent digestibility of cellulose (34.27% vs. 29.61% and 27.49%, respectively for the MOS, control and antibiotic groups) and, as a consequence a higher level of acetate in the caecal content (39.93 mmol/l vs. 34.21 mmol/l and 23.09 mmol/l, respectively for the MOS, control and antibiotic groups). Caecal microflora of the MOS group rabbits also had a higher fermentative activity in respect of protein source, as demonstrated by the higher productions of branched chain fatty acids. MOS and antibiotics significantly reduced the colonies of Coliformis (2.32 vs. 3.20 vs. 2.40 logCFU/g, respectively for the MOS, control and antibiotic groups, p < 0.01). Mannan-oligosaccharides at 1 g/kg of diet can be used as an alternative to antibiotics during the rabbit's growth period.
