Enzyme Supplementation

We evaluated the influence of enzymatic supplementation on the growth performance and cecal microbiota of broilers. A total of 2160 1-day-old male chicks were used in a 3 × 2 × 2 factorial arrangement (three corn hybrids, two drying temperatures −80 and 110 °C, with or without the inclusion of an enzymatic blend (amylase, xylanase, and protease) (20 birds/pen, n = 9). For all performance and digestibility parameters, we observed, in general, isolated effects of the corn hybrids and drying temperature. Birds that received the enzymatic blend in the diet showed better weight gain from 1 to 21 days (d) and better digestibility coefficients of nutrients at 42 d. Birds fed diets with corn dried at 80 °C showed a better feed conversion ratio from 1 to 42 d. At 21 d of age, enzymatic supplementation had positive effects on jejunum morphology. Enzyme supplementation increased the abundance of the phylum Tenericutes, class Bacilli and Mollicutes, reduced Clostridia, and increased the abundances of the families Lactobacillaceae, Anaeroplasmataceae, and O_RF39;F. In conclusion, the addition of amylase, xylanase, and protease led to a better nutrient digestibility, performance, and intestinal morphology. In addition, enzyme supplementation changed the diversity, composition, and predicted function of the cecal microbiota at d 21.

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) and protein resources (soy or rapeseed meals) on gut morphology and protein digestibility of broiler chickens. Three hundred eighty-four male Ross-308 broiler chickens were used with a 23 factorial arrangement with treatments according to a completely randomized design. The morphological examinations of the intestine were carried out on 1-cm long excised segments from duodenum, jejunum and ileum. Adding wheat to the diet increased small intestine length in birds compared to other feedstuffs (P <0.05). Duodenum crypt depth and jejunum villi length were also higher in groups fed with rations containing wheat (P <0.05). Groups that received thyme essential oil and enzyme supplementation had increased length of the duodenum (P <0.05). However, the two- and three-factor interaction effects were not significant. Protein digestibility was not affected by treatment (P >0.05). Feeding wheat to broiler chickens may increase the surface area for nutrient absorption in the small intestine as compensation for the anti-nutritive activity of non-starch polysaccharides in wheat-based diets. Wheat based diets are expected to be acceptable for broilers when supplemented with appropriate enzymes or thyme essential oil.

Lu, H., Adedokun, S. A., Preynat, A., Legrand-Defretin, V., Geraert, P. A., Adeola, O. and Ajuwon, K. M. 2013. Impact of exogenous carbohydrases and phytase on growth performance and nutrient digestibility in broilers. Can. J. Anim. Sci. 93: 243–249. The effect of supplementing corn–soybean-based diets with Rovabio®Max AP, an exogenous enzyme mix with carbohydrase (xylanase and β-glucanase) and phytase activities to broiler chickens was evaluated. Male Ross 708 broilers were assigned to four diets: positive control (PC), negative control (NC), deficient in metabolizable energy (ME), crude protein (CP), calcium (Ca) and non-phytate phosphorus (nPP), relative to the PC, by 100 kcal kg−1, 5 g kg−1, 1.1 g kg−1and 1.6 g kg−1, respectively, in the starter and grower diets; and NC+Rovabio®at 0.05 or 0.075 g kg−1diet. Starter diets were fed from day 0 to day 21 and grower diets from day 22 to day 42. Body weight (BW) and body weight gain on days 22 and 42 were increased (P<0.05) by enzyme supplementation. Enzyme addition increased (P<0.05) feed intake from day 22 to day 42 and overall (day 0 to day 42). Gain to feed ratio (G:F) was significantly increased (P<0.05) with enzyme supplementation during both starter and grower phases. Enzyme addition increased (P<0.05) serum phosphorus (P) concentration on day 21. On day 42 enzyme supplementation increased (P<0.05) the apparent ileal digestibility of P, dry matter (DM), energy, and N. Addition of a combination of carbohydrases (xylanase and β-glucanase) and phytase to corn–soybean-based diets deficient in ME, CP, Ca and P resulted in a significant increase in growth performance and utilization of P, DM, energy and N in broiler chickens.

The purpose of the study was to evaluate the amount of raffinose-series oligosaccharides (RSO) in soybean meal (SBM), whole white lupin seed meal (WLM), sunflower meal (SFM), and rapeseed oil meal (ROM) and to determine whether partial or complete dietary WLM replacement affected the numbers of bacteria in selected groups in the microbiota of broiler chickens and ducks without inducing any weight loss. Total counts of anaerobes, lactobacilli, bifidobacteria, and Escherichia coli in caecal samples from both ducks and broiler chickens, as well as in a crop chyme, in broiler chickens, were determined. Live weights before slaughter were determined. Both broiler chickens and ducks were fed a control diet with SBM (L<sub>0</sub>) or diet containing 50% or 100% WLM as a substitute for SBM (groups L<sub>50</sub> and L<sub>100</sub>, respectively). In comparison with SBM, WLM contained significantly higher amounts of RSO, and the amounts of oligosaccharides in SFM (1.73 ± 0.26 g/100 g) and ROM (1.79 ± 0.14 g/100 g) were negligible compared to those in WLM (8.26 ± 0.14 g/100 g) and SBM (6.96 ± 0.21 g/100 g). The inclusion of lupin in chicken diets did not significantly affect the monitored bacterial groups in crop chyme, but a complete replacement of SBM with WLM (L<sub>100 </sub>group) in chicken diets significantly (P ≤ 0.05) increased the counts of lactobacilli in caecal samples. Partial (L<sub>50 </sub>group) and complete (L<sub>100 </sub>group) lupin supplementation in the duck diet significantly (P ≤ 0.05) increased counts of lactobacilli and bifidobacteria by at least one order of magnitude. E. coli counts in poultry were not affected by changes in diet. The results of our study indicate that partial dietary replacement of SBM with WLM did not significantly affect the live weight of broiler chickens and ducks, but that complete replacement of SBM with WLM may lead to weight loss.

This study was conducted to investigate the effect of maize and yam peels meal based diets with and without enzyme supplementation on the growth performance and nutrient digestibility of broiler chickens at finisher phase. One hundred and eighty (180), one day-old broiler chicks were fed six diets in two groups. The experiment was arranged in a 2 × 3 factorial experimental layout of two levels of enzyme (0g/100kg diet and 50g/100kg diet) and three levels of yam peels inclusion (0kg, 15kg and 30kg). Each treatment was replicated 3 times consisting of 10 chicks per replicate. The experiment lasted 4 weeks. Main effect of graded levels of yam peel meal and enzymes supplementation on growth performance of starter broiler chickens showed significant (P ? 0.05) influence on final weight, total weight, total weight grain and daily weight grain. Birds fed 0% YPM recorded higher statistical value of 2549.00g for final weight. Interaction effect of YPM and enzyme showed significant (<0.05) effect on growth performance of finisher broiler chickens. Final weight, total weight gain and daily weight gain were significantly (<0.05) influenced by interaction of YPM and enzyme. Birds fed control diet (T1 ) recorded higher significant (P<0.05) values for final weight of comparative level. Least value of 2220.00g was recorded for final weight in the birds fed 15% YPM without enzyme (T2 ). Varying levels of YPM as a partial replacement for maize had no significant (P>0.05) effect on nutrient digestibility. Higher values were recorded for birds fed 0% inclusion level of YPM across the parameter determined with the exception of ether extract and ash. Inclusion of YPM with enzyme supplementation had significant (P<0.05) interaction effects on percentage dry matter digestibility, crude protein digestibility and crude fibre digestibility. Dry matter digestibility decreased with increased level of YPM with or without enzyme. Inclusion of yam peels meal up to 30% level of replacement for maize with or without enzyme supplementation could be recommended for appreciable nutrient digestibility and improved growth performance of finisher broiler chickens.

AbstractFor several years in Europe, there has been a growing interest in the use of native sources of protein (e.g. lupine seeds) in poultry nutrition. The current study aimed to investigate the effectiveness of a microbial phytase in broiler diets with the addition of different levels of white lupin seeds. A total of 480 one-day-old male broiler chickens (Ross 308) were randomly divided into six dietary treatments (10 replications/8 birds per group). The basal diet contained SBM as the main protein source and experimental treatments were prepared with white lupin meal (WLM) at 3 levels (0, 10, and 20 %) and with or without phytase inclusion. The experiment was divided into two feeding periods: from 1 to 14 day (starter) and from 15 to 35 day (grower). Diets with phytase addition were deficient in Ca, and nonphytate P. All diets were fed in mash form and offered ad libitum. On day 35th excreta were collected and on day 36th, ten chickens from each group were euthanized and blood, tibia, and digesta samples were collected for further analysis. The 20 % addition of WLM negatively increased the content of phytic-P. The results showed that feed conversion ratio (FCR) and body weight gain (BWG) were not affected by phytase inclusion but by the WLM level alone. In addition, birds fed the diet with 20% WLM were characterized to have the lowest BWG and the highest FCR of all groups. There were no significant differences in feed intake (FI) among chickens fed control and experimental treatments. Regardless of the white lupin level addition, phytase addition improved (P<0.001) nitrogen-corrected apparent metabolizable energy (AMEN). In conclusion, the addition of phytase positively influenced the performance and availability of minerals (Ca and P) regardless of the level of WLM used. However, with regard to the use of WLM in poultry nutrition, it can be assumed that 10 % addition is safe and does not affect performance.
