“…Previous studies, regarding the effects of EO and enzymes on growth performance in piglets, are not always consistent. Similar to present study, EO and XB supplementation did not improve ADG in piglets fed wheat barley-based diets (Muhl and Liebert, 2007;Owusu-Asiedu et al, 2010). In contrast, increased growth performance was reported by other authors (Fan et al, 2009;Maenner et al, 2011).…”

“…In addition, increased BW with age of the piglets may result in decreasing P absorption and retention (Kemme et al, 1997). Many studies reported that EO or enzymes improved apparent ileal digestibility of nutrients of weaned piglets (Emiola et al, 2009;He et al, 2010;Owusu-Asiedu et al, 2010;Maenner et al, 2011). In our study, EO and EO + XB supplementation increased Ca and P digestibility of piglets, but no effect of XB was observed suggesting that the effect obtained when the two additives were combined was primarily due to EO.…”

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.

“…On the other hand, exogenous enzyme supplementation improved average daily gain of pigs fed diets containing barley, hull-less barley or wheat (Bedford et al, 1992;Van Lunen et al, 1996;Baidoo et al, 1998). As in the present study, despite the fact that performance parameters were not improved, feed efficiency could still be improved by carbohydrase supplementation (Owusu-Asiedu et al, 2010). In the latter study the duration of the study was similar to the present study (40 days) and the diets used were barley-wheat based.…”

“…The supplementation of NSP degrading enzymes in pig diets have had inconsistent effects (Owusu-Asiedu et al, 2010;Adeola & Cowieson, 2011), which could be attributed to the fact that the specific proportions of each enzyme especially related to feed substrates has not yet been completely clarified (Owusu-Asiedu et al, 2010). Performance parameters and nutrient digestibility may not always be improved by the addition of exogenous enzymes in diets containing rye or barley (Thacker et al, 1992;Baas & Thacker, 1996;Zijlstra et al, 2004).…”

The present study investigated the modification of feed formulations by replacing cereals with fat and supplementation with lysolecithin and/or multi-non-starch polysaccharides (NSPs) enzyme upon performance. The study implemented 480 weaned piglets starting at 8.1 kg and finishing at 27.6 kg. Piglets were assigned to four treatments (control, control supplemented with fat at 7.0 g/kg, control supplemented with lysolecithin at 0.5 g/kg, with lysolecithin and a multi-NSP enzyme at 0.5 g/kg each). The study was divided in first phase 1-15 days and second phase 16-40 days. Feed conversion was significantly improved in the group supplemented with lysolecithin and multi-enzyme compared to control during the second phase of the experiment (P < 0.05), while the rest performance parameters did not differ significantly between treatments.

“…The viscosity-increasing effect of NSP and their negative effects on digestion are well explained in literature (Hansen et al, 1992;Yin et al, 2000;Hogberg and Lindberg, 2004a, b). Supplementation of exogenous NSP-hydrolyzing enzymes to diets rich in NSP (e.g., from fiber-rich by-products such as DDGS) can, therefore, improve digestibility and subsequently the performance of monogastric animals (Emiola et al, 2009;Owusu-Asiedu et al, 2010). Owing to the high amounts of fiber, the increase in DDGS demands an increase in dietary fat addition in the diet to keep the energy level constant (Thacker and Widyaratne, 2007;Schedle et al, 2010a).…”

SummaryThe objective of the current study was to determine the applicability of wheat-corn-distillers dried grains with solubles (DDGS) as protein source with and without non-starch polysaccharides (NSP)-hydrolyzing enzymes in diets of broiler chicks. In addition to the performance and carcass characteristics, the effect on energy parameters (energy intake per day, energy per kilogram feed), digestibility, as well as sensory aspects and fatty acid profile of breast meat were determined. In a 3×2-factorial approach, a total of 360 broiler chickens (Ross 308) were allocated to six treatment groups (8%, 16%, and 24% DDGS, with or without NSP-hydrolyzing enzymes). The zootechnical performance was not influenced by increasing DDGS concentrations over the whole fattening period, whereas supplementation of the NSP-hydrolyzing enzyme improved feed conversion ratio in the grower phase and increased average daily gain (ADG) in the finisher phase (p < 0.05). Energy and dry matter (DM) digestibility as well as apparent N retention did not differ between treatments. The substitution of soybean meal and corn with DDGS and vegetable oil showed a trend of increased tenderness of broiler breast meat. Nevertheless, the intramuscular amount of polyunsaturated fatty acids increased with increasing inclusion rate of DDGS and vegetable oil (p < 0.01). Keywords
