Enzyme Supplementation

This study was conducted to investigate the performance and nutrient digestibility in broiler chicks as influenced by multi-enzyme (Hemicell +Roxazyme G) addition to starter diets containing palm kernel meal. Nine experimental diets were formulated such that diet 1 which served as control contained 0 % PKM without enzyme supplementation. Diet 2, 3, 4 and 5 contained 10, 20, 30 and 40 % PKM levels respectively with multi-enzyme supplementation while diets 6, 7, 8 and 9 contained 10, 20, 30 and 40 % PKM inclusion levels respectively without multi-enzyme supplementation. Five hundred and forty (540) day old hybro broilers of mixed sex in ratio (1: 1) were randomly assigned to nine diets in a completely randomized design. Each treatment was replicated thrice with 20 birds per replicate. The experiment lasted 35 days. The results showed that nutrient digestibility in the control and 10 % PKM with enzyme supplementation were similar but were significantly (P<0.05) higher than other PKM diets with or without supplementation. There was significant (P<0.05) improvement in body weight and body weight gain and reduce feed intake with supplementation. Birds fed with 20 % PKM with enzyme showed similarity with control birds in all the performance parameters measured. Enzyme addition significantly (P<0.05) reduced cost of feed consumed at 30 % level of inclusion with PKM while cost per kilogram weight gain and cost of production were lower at 20 % PKM level.

Dietary Treatments

In this experiment, we investigated the effect of increasing levels of palm kernel meal containing α-β-mannanase replacing maize to growing-finishing hybrid duck on growth performance, nutrient digestibility, and carcass trait. One hundred and ninety- six hybrid ducks [(Peking x Khaki Campbell)] with 410.52 ± 95.25 g BW) were allotted to 5 dietary treatments with 9 ducks (unsexed) per pen and 4 replicates per treatments. These dietary treatments were: NC (negative control; maize-soybean-meal based diet), PKM25 (maize replacement with PKM α-β-mannanase 25%), PKM50 (maize replacement with PKM α-β-mannanase 50%), PKM75 (maize replacement with PKM α-β-mannanase 75%), PKM100 (maize replacement with PKM α-β-mannanase 100%). There was a curve linear decrease in the growing phase and finisher phase in feed intake as the level of α-β-mannanase palm kernel meal increased in the diet. Curvilinear, the result was presented no significant difference (P>0.05) on the initial body weight, growing and finishing phase body weight. The result of this study showed the used α-β-mannanase in the palm kernel meal presented a significant difference (P < 0.05) on the nutrient digestibility of dry matter and crude protein. Furthermore, Carcass traits showed the reflection in line with the final weight and internal organs were better to compare to control 0.5% using α-β-mannanase in the palm kernel meal. In summary, the increase of the level of palm kernel meal with α-β-mannanase enzyme was had a positive effect on the hybrid ducks and the replacement of palm kernel meal by 25% with the addition of the α-β-mannanase enzyme was able to improve digestibility and reduce abdominal  fat of hybrid ducks.

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.
