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.

Dietary Treatments

A study was conducted at the Abubakar Tafawa Balewa University (ATBU) Research and Teaching Farm between December and May 2006 to determine nutrient intake, digestibility and growth performance in Yankasa rams fed urea-treated (UTRS) and untreated rice straw (URS) with supplementation. Thirty-two (32) Yankasa rams with an average weigh of 17.5kg, and aged 1.5 to 2 years old were alloted to eight (8) dietary treatments with four (4) rams per treatment in a 2 x 4 factorial design. The two basal feeds were urea0treated rice straw (UTRS) and untreated rice straw (URS). The supplements were maize bran (MB), MB + sun-dried poultry litter (MB + SDPL), MB + ensiled poultry litter (MB+ EPL) and MB + cotton seed cake (MB + CSC). Total dry matter intake (TDMI), daily basal feed intake (DBFI) were significant (P<0.05) across dietary treatments. Animals on supplements MB and MB+CSC for both UTRS and URS recorded the lowest and highest DBFI. The digestible crude protein intake (DCPI) and digestible organic matter intake (DOMI) were high for rams on UTRS and the values ranged from 17.72 to 28.36g/d and 288.81 to 482.66g/d for DCPI and DOMI respectively. Nutrient digestibility was improved by treatment of straw and supplementation. However, crude protein digestibility was similar for animals fed URS but, significantly (P<0.05) lower compared to those fed UTRS which were also similar across supplements. Average daily weight gain ranged from 53.58 to 91.18g/d across dietary treatment with animals on supplement MB recording the lowest (53.58 and 61.43g/d for URS and UTRs respectively) and those fed supplement MB+CSC the highest (81.38 and 91.18g/d fro URS and UTRS respectively) irrespective of straw treatment. Feed conversion ratio (FCR) was least for animals on supplement MB+CSC for both URS and UTRs, indicating that this supplement (MB+CSC) influenced feed utilization more positively. From the results of this trial, it may be concluded that straw treatment and/or supplementation can enhance crop residue utilization by sheep. however, mixed supplements especially MB+CSC were more efficient in enhancing the utilization of the straw and consequently animal performance.

The aim of this work was to study the continuous or intermittent impact of a multienzyme supplement on growth performance, nutrient digestibility, and blood metabolites of broilers, and to evaluate production index of dietary supplementation. A total of 315 unsexed day-old Arbor Acres broiler chicks were randomly distributed to seven treatments groups, keeping initial body weights similar, in 35-floor pens (replicates) of nine chicks per replicate (pen) and five experimental units per treatment. All experimental groups were fed the same basal diet and administered seven multienzyme treatments: the 1st group (control) did not receive any enzyme supplementation; the 2nd, 3rd, and 4th groups were administered multienzymes at 0.5, 1.0, and 1.5 mL/L drinking water, respectively. Each enzyme supplemented-group was divided into two subgroups, with additives being applied either continuously (24 h/day) or intermittently (12 h/day) from 1 to 35 days old. Regardless of administration method, multienzyme supplements at 1.0 mL/L water along with a corn-soybean meal diet increased the body weight gain (BWG) by 7.8% compared to 0.5 mL/L water during days 1–21 of age. In addition, 1.5 mL/L water significantly improved BWG by 5.1% of broilers compared to 0.5 mL/L water during days 1–35 of age. Enzyme supplementation at 1.5 mL/L water significantly enhanced feed conversion ratio (FCR) by 4.3% during days 1–21 of age, and FCR by 5.2% and European production index (EPI) by 10.4% during days 1–35 of age compared to the group on 0.5 mL/L water. For the whole period, there were improvements of beneficial consideration in BWG (4.0%), FCR (4.0%), and European production index (8.2%) due to continuous multienzyme supplementation at 0.5 mL/L water compared to the same dose added intermittently. A similar trend was observed due to intermittent multienzymes at 1 mL/L drinking water that resulted in increased BWG by (6.4%) and improved FCR by (6.7%) and EPI by (12.7%). Intermittent administration significantly increased feed intake of broilers during 22–35 days of age compared to continuous supplementation. Multienzymes at different doses did not significantly affect the digestibility of nutrients, blood serum biochemical constituent, inner body organs, and markers of functions of liver and renal organs. In conclusion, the highest BWG and the best FCR and EPI for the whole period were from broilers given continuous 1 and 1.5 mL/L drinking water or intermittent multienzyme supplementation at 1.5 mL/L drinking water. Furthermore, intermittent supplementation of enzymes at 1 mL/L drinking water and continuous supplementation at 0.5 mL/L drinking water can be investigated in further experiments as a tool to improve broiler growth performance and economic traits and to decrease the cost of enzyme application.

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.
