“…cellulase, xylanase, etc.) are capable of disrupting plant cell wall integrity, consequently, this enhances rapid digestion by reducing viscosity in the gut (Zijlstra et al, 2010;Bedford & Cowieson, 2012). Apart from the potential of exogenous enzymes to enhance nutrient utilisation and growth (Adeola & Cowieson, 2011), they may alter substrates availability for specific populations of gut microbes, thus, altering bacterial community composition or activities (Bedford and Cowieson, 2012;Kiarie et al, 2013;Zhou et al, 2013;Jiang et al, 2014).…”

A 60-day feeding trial was conducted to study the nutrient utilization and growth performance of Labeo rohita fed with T1 [DORB supplemented with phytase and xylanase (0.01% each)], T2 [ T1+ L-lysine(1.4%), L-methionine (0.4%), combination of EPA and DHA (0.5%)] , T3 [DORB supplemented with phytase (0.01%), combination of xylanase and cellulase (0.075%), L-lysine (1.4 %), L-methionine (0.4 %), combination of EPA and DHA (0.5%)] and T4 (commercially available carp feed) diets. Weight gain%, SGR, and FCR were similar (p>0.05) for the fishes fed with either T3 feed or commercial carp feed (T4), whereas PER was highest for the T3 group. A significantly higher apparent dry matter and carbohydrate digestibility were observed in the T3 group. Highest crude protein digestibility was observed in T4 group, though lipid digestibility was similar in both T3 and T4 groups. The activities of digestive enzymes were similar in T2, T3 and T4 groups, whereas the lowest activity of these enzymes were observed in T1 group. Based on the findings it is concluded that T3 feed (crude protein 18.18 %) is having comparable growth performance of Labeo rohita as compared to T4 diet (crude protein 32.01 %) due to higher In vivo digestibility.

“…Previous studies indicated that certain essential oils (EO) and enzymes might have beneficial effects on animal performance and health status because of other properties besides their respective functional characteristics (Windisch et al, 2008;Zijlstra et al, 2010). Numerous studies have shown that thymol and carvacrol in vitro exhibit antibacterial effect (Dorman and Deans, 2000;Lambert et al, 2001;Burt, 2004), and cinamaldehyde from cinnamon has shown to have antimicrobial effects (Mancini-Filho et al, 1998).…”

“…Improvements of digestibility were reported for the enzyme supplementation of wheat-based diets in pigs (Diebold et al, 2004;Woyengo et al, 2008;Emiola et al, 2009). Moreover, enzymes supplementation would affect some components of gut health and intestinal barrier, including intestine structure, bacteria populations and microbial metabolites released in the gut lumen (Zijlstra et al, 2010). The administration of enzymes such as a combination of XB improves growth performance in piglets due to increased nutrient digestibility (Omogbenigun et al, 2004;Kiarie et al, 2007;Fan et al, 2009).…”

The aim of this study was to test the hypothesis of an improved gut environment of post-weaning piglets when administered a blend of essential oils (EO; thymol and cinnamaldehyde) and an enzyme combination (xylanase and β-glucanase (XB)) either alone or in combination. To assess the effect of dietary treatments, faecal nutrient digestibility and microbial counts, as well as ileum histology and gene expression of inflammatory mediators were evaluated. One hundred and ninety-two weaned piglets were allocated into four experimental treatments, and fed the basal diet (CTRL) either without or with EO, XB or their combination (EO + XB) for a 42-day period. The experiment concerning digestibility was designed with two periods (period I: days 15 to 21; period II: days 29 to 35) and the faeces were collected on days 20, 21, 34 and 35. On day 42, six piglets from each treatment were slaughtered. It was found that EO, XB and EO + XB supplementation did not affect ( P > 0.05) the growth performance of the piglets from days 0 to 42. Moreover, no dietary effect on faecal score was observed. Faecal digestibility of dry matter, organic matter, ash, dietary fibre, lipid, CP and NDF were increased from period I to period II ( P < 0.01 to P = 0.06), while no effect ( P > 0.05) of EO, XB or their combination on the faecal digestibility was observed at both periods. Compared with the CTRL diet, dietary XB reduced the faecal Lactobacillus and Escherichia coli counts but increased the Lactobacillus to Coliforms ratio on day 42 ( P = 0.02, 0.03 and 0.03, respectively), and all the additives supplementations decreased the counts of faecal Coliforms on day 42 ( P < 0.01). XB supplementation increased the villus to crypt ratio ( P = 0.04) and reduced the mucosal macrophages number ( P < 0.01) in the ileum compared with the CTRL group, and dietary EO or EO + XB decreased the number of lymphatic follicles ( P = 0.01 and P < 0.01, respectively) and mucosal macrophages ( P = 0.02 and P < 0.01, respectively). In addition, the interleukin (IL)-1α was downregulated in piglets treated with EO + XB compared with the EO group (P = 0.02). In conclusion, the administration of EO, XB or their combination was effective in improving ileum histology, and EO + XB supplementation might benefit the modulation of the expression of ileum inflammatory cytokines in piglets.

“…Supplementation of multienzyme in proper combination and proportion play an important role in efficient and effective nutrient utilization of diets containing high fibre (Zijlstra et al, 2010). But now since most of the feeds are formulated under Total Mixed Ration (TMR), there is every need to improve the fibre forage digestibility.…”
