Enzyme Supplementation

The influence of bacterial and fungal enzyme supplements at 0.1 5 and 0.30% of barley based diets on the growth and nutrient utilization of female broiler chickens (Tegel strain) was studied in three experiments. All diets were based on Australian barley cultivars and were fed as mash. Body weight gain was improved by 12 to 25% and food consumption increased by 3 to 21% in supplemented treatments at 4 weeks of age. Diets based on the cultivars Clipper, Ketch and Noyep each grown at Coonalpyn, Port Pirie and Ardrossan in South Australia gave similar growth responses to enzyme supplementation. The metabolizable energy content of the diets was improved by 0.75 MJ kg-1 and 1.53 MJ kg-1 dry matter. An examination of the utilization of dietary nitrogen, soluble sugar, starch, pentosans and soluble �-glucan could not account for the improved metabolizable energy.

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.

Enzyme Application

Despite of high production of barley in Iran, its use in poultry diets is limited due to low energy content and problems such as sticky droppings. Barley cultivars have different nutritive value for broilers (Villamide, et al., 1997) and enzyme application may affect barley cultivar based diets differently. β-glucanase supplementation of barley based diets can eliminate β-glucan, the main anti-nutritional factor of barley, and improve nutrient digestibilities and apparent metabolizable energy. The objective of this trial is to study the β-glucanase effect on nutrient digestibilities and apparent metabolizable energy corrected for nitrogen (AMEn) of different barley cultivar based diets.

Two hundred and forty Arbor Acre strain day old chicks were used to determine the effect of Maxigrain® enzyme fortification of dietary brewers dried grains (BDG). Eight groups of 30 birds each were fed four diets that contain 0, 5, 10 and 15 % BDG with or without Maxigrain in a 2x4 factorial arrangement. The research lasted for 28 days during which data were collected on performance, nutrient utilization and production cost. Significant (P<0.05) increased was observed in average final body weight, body weight gain and feed intake as dietary BDG increased. However, this effect was higher when enzyme was added to BDG respectively. Increasing the BDG from 0 – 15 % significantly (P<0.05) reduced cost of feed consumed and increased feed cost with enzyme addition. The reversed trend was observed with cost per kg gain of broiler chicks fed BDG with enzyme supplementation. Birds fed BDG with enzyme had significantly (P<0.05) better nutrient utilization than their counterpart group. It can be concluded that the incorporation of up to 15 % BDG with 100 mg/kg Maxigrain® supplementation enhanced performance and economics of production

Abstract Two experiments were conducted to investigate the effects of a combined α-galactosidase and xylanase preparation on nutrients digestibility and growth performance in broiler chickens. Experiment 1 had 240 broilers allocated to 3 treatments with the dietary supplementation of 0, 300 and 500 g/t of the enzyme combination. Diet and amino acid (AA) digestibility were assessed. Experiment 2 was a 2 × 3 (enzyme × diet) factorial arrangement with 10 replicates of 12 male broilers per replicate. Diets were based on corn-Soybean meal (SBM) diet and had 3 nutritional levels (normal, 2% apparent metabolizable energy (AME) and crude protein (CP) reduction, and 4% AME and CP reduction). Each of these diets was fed with or without enzyme supplementation. Growth performance, chyme viscosity, nutrients digestibility, and endogenous enzymes activity were assessed. In experiment 1, enzyme supplementation improved the digestibility of Ca (P = 0.025) and ileal digestibility of total AA, Pro, Alu, Ile, Lys, His, Thr, Glu, Val, Leu, Tyr and Phe (P &lt; 0.05), and also tended to increase the AME of diets (P &lt; 0.10). In experiment 2, broilers fed the corn-SBM diet with 4% nutrient reduction had better growth performance (P &lt; 0.05), jejunal digesta viscosity at 42 days (P &lt; 0.01), and lower digestibility of gross energy (GE) (P &lt; 0.05) when compared to those fed the normal nutrient diet. Enzyme inclusion increased digestibility of CP (P = 0.044), GE (P = 0.009), raffinose (P &lt; 0.001) and stachyose (P &lt; 0.001), improved average daily gain (P = 0.031), and reduced jejunal digesta viscosity at 42 days (P = 0.011). Besides, similar improvements trend in amylase, trypsin, sucrase, and maltase activity with enzyme inclusion were observed as with energy. These data support that the enzyme supplementation increased nutrients and ileal amino acid digestibility, improved performance and endogenous enzymes activity.

Abstract. The effect of different phytases on the performance response, nutrient utilization and tibia characteristics of chickens was investigated. The five pelleted diets were the following: positive control (PC) with added monocalcium phosphate; negative control (NC) formulated with equivalency values of phytase for Ca and digestible P; and three further diets where different phytases were individually added to the NC diet at 500 FTU/kg. The phytases were derived either from Aspergillus (phytase I), or E. coli (phytases II and III). Compared to PC, the performance parameters, as well as apparent metabolizable energy (AMEn), mineral retention, bone breaking force and tibia mineral content were suppressed by the reduction of dietary Ca and digestible P. All phytases enhanced the overall body weight gains and feed conversion ratio in comparison with NC, but none outperformed PC. Only phytase II improved AMEn compared to NC and PC group. However only phytase I outperformed NC group in terms of mineral retention and P retention was higher than phytase II and III. No significant differences were observed in fat digestibility and N retention. Bone strength among phytases did not differ and all improved this parameter compared to the NC diet. However, even though all phytases enhanced tibia minerals content, the improvement was less pronounced with phytase III. Moreover, the differences in all analysed tibia minerals between phytase III and II were significant suggesting that even among 6-phytases derived from and expressed in the same organism, different efficacy or mode of action can occur.

A biological experiment of 160 day old chicks for six weeks was undertaken with completely randomized design (CRD) divided into five treatments, each consisting of 4 replicates and 8 chicks in each replicate. Five experimental diets as per ICAR (2013) were prepared by incorporating rice distillers dried grains with solubles (rDDGS) at inclusion level of (0, 7.5, 10.0, 12.5 and 15.0%). Chemical analysis revealed that rice DDGS on as such basis is high in both crude protein 44.68% and gross energy 4232 kcal/kg. In vitro pepsin-pancreatin digestibility (IVPPD) of rDDGS was found 79.81%. At the inclusion level of 7.5, 10 and 12.5 %, growth performance and nutrient utilization did not show any significant (P>0.05) difference as compared to control but at 15% rDDGS inclusion level, growth performance (body weight gain, feed intake and FCR) and nutrient utilization (dry matter and energy metabolizability, nitrogen retention %) were significantly (Pless than0.01) lower in 15% rDDGS (T5) group as compared to control (T1) and other dietary treatments. Carcass traits did not show any significant (P>0.05) difference between control and other dietary treatments. Cost of production per kg live weight and meat yield were significantly (Pless than 0.01) lower in 7.5 % and above rDDGS levels. Thus, it is concluded that rDDGS can be safely incorporated in broiler chickens diets up to the inclusion level of 12.5% as alternate protein meal for economic broiler production.

Standardized ileal digestibility (SID) of amino acids (AA) and apparent metabolizable energy corrected for nitrogen (AMEn) in defatted black soldier fly larvae meal (BSFLM) were determined in broiler chicks. A total of 180-d-old male broiler chicks (Ross 708) were fed a commercial broiler starter diet to day 13 of age. On day 14, birds were weighed and placed in cages (10 birds per cage; n = 6) and allocated one of two semi-purified cornstarch-based diets. The diets were nitrogen-free diet (NFD) for estimating endogenous AA losses and 20% crude protein test diet with BSFLM as the sole source of AA. All diets had 0.5% titanium dioxide (TiO2) as an indigestible marker and the ratio of cornstarch to sucrose and soy oil in the test diet was identical to NFD to calculate AMEn by difference method. Birds were given feed and water ad libitum. Excreta samples were collected on days 17–20 and ileal digesta on day 21. The SID of lysine, methionine, cysteine, threonine, isoleucine, and valine was 86.3%, 88.7%, 72.8%, 85.5%, 89.6%, and 88.6%, respectively. Apparent retention of gross energy in BSFLM was 64.5% ± 2.27% and AMEn was 2902 ± 101 kcal kg−1 dry matter. The data will aid in accurate incorporation of BSFLM in poultry feeding programs.

Pearl millet, which is comparable to maize in terms of its metabolizable energy content is an identified potential replacement for maize in broiler diets. However, as the competition and price of maize continues to spike, the continuous need to completely replace maize in broiler diets is imperative. Therefore, the objectives of this study were to investigate the effects of feeding diets containing pearl millet supplemented with enzyme NatuzymeTM on the carcass characteristics and haematological values of broiler chickens. 150 two weeks-old broilers were randomly divided into 5 groups with 10 birds per pen translating into 10 birds per replicate and fed an isonitrogenous (23%CP) starter diet of control diet (A); 0% (B); 10% (C); 20% (D); 30.01% and (E) 37.41 % pearl millet. Similarly, an isonitrogenous (21%CP) finisher diet of control diet (A); 0% (B); 10.64% pearl millet (C); 21.28% (D); 31.92% and (E) 39.27 % of pearl millet for 6 weeks. The birds were randomly allotted to the diets in a completely randomized design with feed and water given ad libitum. With the exception of drumstick of birds fed diet D which was significantly lower than the other diets, the results showed that the carcass values (parameters) of broilers fed 100% pearl millet were similar or non-superior to the control group and the other diets. Similarly, blood parameters were not significantly different between groups. These results show that pearl millet supplemented with enzyme can replace maize in broiler diets without affecting carcass yields and haematological parameters.
