Energy sparing effect of non-starch polysaccharide degrading enzymes blend in laying hens fed either corn-SBM or wheat-SBM based diets 

M. K. Manangi*, J. Lunnemann, N. Odetallah, R. Buresh, and M. Vazquez-Anon; Novus International, Inc., St. Charles, MO1.

An 8wk (69 to 77wk of age) trial was conducted to evaluate the energy sparing effect of non-starch polysaccharide (NSP) multi-enzyme blend (2000U endo-xylanase, 75U endo-beta-glucanase and 25U alpha-galactosidase/g of product; CIBENZA® CSM feed additive) in laying hens fed iso-nitrogenous corn-SBM and wheat-SBM based diets with varied AMEn levels. A total of 216 Hy-Line W-36 laying hens were assigned to 6 treatments with 36 cages/treatment and 1 hen/cage. The data were analyzed using both 1-way ANOVA (for all 6 treatments) and 2x2 factorial design with 2 diets (corn-SBM vs. wheat-SBM) and 2 energy levels (0 and 80kcal/kg diet reduction). The treatments consisted of: Corn-SBM diet, T1 (2820kcal); T1 less 80kcal, T2; T2+0.05 NSPases blend, T3; Wheat-SBM diet, T4 (2820kcal); T4 less 80kcal, T5; T5+0.05% NSPases blend, T6. Measurements included were weight gain, cumulative (c) feed intake (FI), cFCR on egg mass, egg production, egg weight and viscosity (jejunal and ileal). Reduction of 80kcal reduced (P<0.05) weight gain in wheat based diets (T5) compared to T4, while supplementation of NSPases (T6) brought back the performance that was similar (P>0.05) to +ve control (T4). FI was reduced and FCR on egg mass improved (P<0.05) in hens fed diets supplemented with NSPases (T3 and T6) compared to their respective –ve controls (T2 and T5) and further these variables were either the same (P>0.05) or better than their respective +ve controls (T1 and T4). Viscosity for T6 was reduced (P<0.05) compared to T4 and T5 and was similar to T1, T2, and T3 (P>0.05). Factorial output indicated an improvement in weight gain (by 28g), FCR (by 13 points) and FI (5g less) for hens fed NSPases compared to non-NSPases fed groups (enzyme effect, P<0.05). Supplementing wheat based diets increased weight gain by 26g, reduced FCR efficiency by 12 points, and increased FI by 5g/d compared to hens fed corn based diets (diet effect, P<0.05). In summary, NSP enzymes could spare 80kcal/kg diet in laying hens without compromising production and FCR irrespective of diets tested while reducing intestinal viscosity in wheat based diets.

A 15 week (wk 21-36) study was conducted in a commercial broiler breeder facility to determine the impact of feeding reduced levels of MINTREX® (metal methionine hydroxy analogue chelate) vs. industry levels of ITMs (inorganic trace minerals) in breeder hens on egg quality, hatching rate and progeny quality. A total of 15200 male line of Hubbard breeder hens were distributed into 4 houses (with floors having 1/3 slats and 2/3 litter) with 3800 hens/house. Study had 2 treatments (T1 and T2) each with 2 replicate houses per treatment and consisted of 56, 14 and 56ppm of Zn, Cu and Mn, respectively, as chelates (T1), and 100, 10 and 100ppm of Zn, Cu and Mn, respectively, as oxide, sulfate, and oxide (T2). At wk 36, 210 eggs per house were evaluated for average egg weight and egg shells breaking strength, and 4150 eggs per house were monitored to evaluate hatching rate. At birth, 50 left tibias per house (100 chicks per treatment) were sampled and pooled for tibia ash, and tibia Zn analysis on DM basis to assess progeny quality. No differences were observed for egg weight (P=0.99) and shell breaking strength (P=0.14) between treatments. Hatching rate significantly (P=0.048) improved by 1.92% for group fed chelated minerals compared to group fed ITMs. Ash content of chicks produced from hens fed chelated minerals increased by 4.3% (P=0.02) and tibia Zn content increased by 3% (P=0.19). In summary, present data indicated that feeding broiler breeder hens the reduced levels of supplemental chelated trace minerals compared to ITMs improved hatching rate and progeny quality.

A 42 d trial was conducted to determine the response of MINTREX® (metal methionine hydroxy analogue chelate) vs. industry levels of ITMs (inorganic trace minerals) on performance, immune response, and litter trace minerals concentration by feeding broiler chicks diets containing varied levels of supplemental Zn, Cu and Mn as chelates in comparison to industry levels of inclusion of respective inorganic trace minerals (ITM). A total of 2,100 Ross 308 male broiler chicks were randomly assigned to 6 treatments with 10 pens/treatment and 35 chicks/pen. The wheat-SBM based basal diet (T1) was devoid of any added Zn, Cu or Mn. T2, T3 and T4 received incremental levels of chelated minerals’ at 16-4-16, 32-8-32, and 48-16-48ppm of Zn-Cu-Mn, respectively. T5 and T6 received industry levels of trace minerals (70-20-80ppm of Zn-Cu-Mn) either as chelates (T5) or as ITMs (T6). End of the study results indicate significant (P<0.05) treatment effects for weight gain , immune response, and litter minerals concentration. The chicks fed 32-8-32ppm or higher levels of Zn-Cu-Mn as chelates gained 38g more weight (P<0.05) compared to T1 whereas chicks in T2 and T6 performed the same as T1 (Basal diet). Chicks fed higher levels (T4 and T5) of chelated trace minerals gained 34 to 40g more weight compared to T6 (P<0.05) but performed the same as T3 (P>0.05). Infectious Bronchitis antibody titers measured at d 35 indicate significant improvement (P<0.05) in titer response for T3 compared to T5. As expected increasing levels of dietary trace minerals resulted in increased levels of trace minerals in the litter. In summary, the present data indicate that the supplemental ITMs were effectively replaced with reduced levels (32-8-32ppm of Zn-Cu-Mn) of chelates without compromising bird immune response while achieving improvement in weight gain and reduction in litter trace mineral concentration.

One battery study was conducted to evaluate effect of a synthetic 1:1 thymol carvacrol blend (NEXT ENHANCE® 150) on growth performance and gut health of broilers fed rye wheat based diet and challenged with mixed species of Eimeria on day 0. A rye wheat and soybean meal based diet was formulated to meet or exceed nutrient requirements of broilers. To this basal diet, the essential oil blend was added at 0, 30, 60, or 120 g/ton to provide 0, 15, 30, or 60 g/ton essential oils, in which half was thymol and half was carvacrol. BMD at 50 g/ton and a nonstarch polysaccharides (NSP) degrading enzyme blend (containing xylanase, ?-glucanase, and ?-galactosidase; CIBENZA® CSM, Novus International, Inc.) at 500 g/ton served as positive controls. Each of the 6 test diets was fed to 8 replicate pens of 8 male broilers from 0 to 31 day of age. Growth performance was measured at day 7, 14, 21, and 29. Gut health parameters measured were serum uric acid and ?-1 acid glycoprotein on day 7, ileal Clostridium perfringens on day 15, ileal Lactobacilli on day 30, and digesta viscosity on day 31. Data were analyzed by one-way ANOVA and statements of significance were based on P<0.05. Essential oil blend at 60 g/ton significantly improved overall body weight by 14% (1012 g versus 886 g) and FCR by 15 points (1.869 versus 2.019) and its effect was not significantly different from BMD. The NSP enzyme blend significantly increased body weight, feed intake and improved FCR and the effect was greater than BMD or essential oil blend. Only the NSP enzyme blend significantly reduced digesta viscosity. Serum ?-1 acid glycoprotein and uric acid concentration, and ilealClostridium perfringens and Lactobacilli counts were not significantly affected by dietary treatments. The study demonstrated that an essential oil blend delivered a similar improvement in performance to BMD in broilers under gut health challenge and could be an effective tool in antibiotic free broiler production.

Effect of dried distillers grain with solubles (DDGS) and rye on growth performance and gut health of broilers as affected by enzyme supplementation

F. Yan, J. Dibner, M. Vazquez-Anon and C. Knight

Novus International Inc. St. Charles, MO

A study was conducted to evaluate effect of high levels of corn DDGS and rye on growth performance and gut health of broilers as influenced by a nonstarch polysaccharides (NSP) degrading enzymes blend (CIBENZA® CSM, Novus International, Inc.). The study consisted of 8 treatments: corn soy control, 30% DDGS, 16% corn bran, 38% rye, 38% rye plus enzyme, 25% rye, 25% rye 30% DDGS, and 25% rye 30% DDGS plus enzyme. Corn bran at 16% provided the same level of crude fiber as that contained in 30% DDGS. Each diet was fed to 8 replicate floor pens of 21 male broilers. Body weight, feed intake, FCR, and mortality were determined at 19, 35, and 42 d. Ileal Clostridium perfringens (Cp) on d 28, and digesta viscosity on d 43 were measured. Data were analyzed by one way ANOVA and statements of significance were based on P < 0.05. Incorporation of 30% DDGS to corn soy diets decreased body weight at d 19 and 35 and increased FCR throughout the trial, whereas birds fed diets containing 16% corn bran performed equally or better than control birds, suggesting fiber might not be a critical factor in limiting high levels of DDGS in broiler diets. Inclusion of 30% DDGS in diets containing 25% rye did not significantly affect performance of broilers. Birds fed diets containing 25% rye weighed less and had higher FCR; increasing rye to 38% did not further worsen growth performance. Enzyme significantly improved weight gain and FCR throughout the trial when it was added to diets containing 38% rye; and the effect was slightly less when it was added to diets containing 25% rye and 30% DDGS. Rye inclusion increased digesta viscosity and enzyme addition significantly reduced it. Mortality at 35 or 42 d was positively correlated with both digesta viscosity and ileal Cp level. In summary, high levels of DDGS and rye were detrimental to broiler performance and NSP degrading enzymes improved growth performance and gut health of broilers when rye or rye and DDGS were present.

Comparison of DL-selenomethionine with other sources of selenium on performance, glutathione peroxidase activity and tissue selenium concentration in young broilers

F. Yan, B. Wuelling, and M. Vazquez-Anon

Novus International Inc. St. Charles, MO

A battery study was conducted to evaluate effect of different sources of selenium (Se) on growth performance, glutathione peroxidase (GPx) activity and tissue Se deposition of young broilers. A semi-purified diet containing corn starch, dextrose, and torula yeast was formulated to meet requirement of broilers for all nutrients except Se. The Se level was formulated to be 0.11 ppm but analyzed to be 0.23 ppm. The study consisted of 9 treatments - negative control with no added Se; 0.30 ppm added Se provided by sodium selenite (SS), DL-selenomethionine (DL-SeMet) (MINTREX® Se, Novus International, Inc.), two commercial selenized yeast products, methylselenocysteine (MeSeCys), or combination of SS and SeMet with each providing 0.15 ppm added Se; and 0.15 ppm added Se from SS or DL-SeMet. Each of the 9 test diets was fed to 8 replicate pens of 8 male broilers. Body weight, FCR, feed intake, and mortality were measured on d 6, 13, 20 and 27. Plasma and liver GPx activity was determined on d 7, 14, 21, and 28. Liver and breast Se concentration was analyzed on d 28. On d 35, breast muscle, liver, kidney, and skin/fat samples were taken for Se determination. Data were subject to one-way ANOVA with statements of significance based on P<0.05. Despite of semi-purified diet, birds from all treatments performed well with optimal growth rate and FCR. Growth performance and GPx activity were not significantly affected by dietary treatments throughout the trial. On d 28, DL-SeMet increased concentration of Se in both liver and breast whereas selenized yeast, MeSeCys, and SS significantly increased liver Se concentration only. On d 35, breast muscle, liver, kidney, and skin/fat Se concentration was increased significantly only by DL-SeMet. In summary, DL-SeMet was more available for deposition in liver, breast muscle, kidney, and skin/fat than selenized yeast, SS, or MeSeCys when added to provide 0.15 or 0.30 ppm Se in young broiler diets.
