Fifty-four samples of wheat, representing duplicate samples of nine varieties grown in three environments, were included in chick bioassays using rapidly growing broilers, complete diets, and enzyme supplementation to remove the deleterious effects of non-starch polysaccharides. An insoluble ash marker was included in the diets, which allowed calculation of apparent digestibilities of CP and AA in the grain from analysis of the ileal contents obtained after sacrifice of the chicks at 17 d of age. The wheat cultivars contained from 13.5 to 16.8% CP and differed in the percentage of specific AA, with Pro, Glu and Phe making up proportionately larger parts of high CP samples than low CP samples. Without enzyme supplementation, the digestibility of CP varied from 83 to 88% and that of specific AA from 76 to 94%, determined in part by the class and variety of wheat. Xylanase enzyme supplementation improved the digestibility of protein by an average of 4%, and reduced the differences in digestibility between wheat samples. These results suggest that variation between wheat samples should be taken into consideration when formulating broiler feed, especially when formulation is for specific AA. Enzyme supplementation may provide a partial alternative to using high-quality protein sources or supplementing with synthetic AA.

Corn-Cob Meal (CCM) is a waste product derived from maize grain shelling corn cob which constitutes nuisance to the environment and it can be included in poultry diet in order to reduce competition between man and animal. Hence, a 63-day feeding trial was conducted in a completely randomized design to determine performance characteristics and blood profile of broiler chickens fed corn-cobs based diets with or without enzyme supplementation. One hundred and sixty five (165) birds were randomly allotted into five dietary treatment groups; T1: (0% CCM), T2 (10% CCM without enzyme), T3 (20% CCM without enzyme), T4 (10% CCM with enzyme), T5 (20% CCM with enzyme) with each treatment comprising three replicates of eleven birds per replicate. Parameters measured include performance characteristics, haematological and serum biochemical indices. The result revealed that there were no significant difference (P>0.05) on performance characteristics of broiler chicken observed except for Average Daily Feed Intake (ADFI) and the Feed Conversion Ratio (FCR). Birds fed 10% and 20% CCM based diet without enzyme recorded the highest value of ADFI (129.38 g/b/d and 130.85 g/b/d) while birds fed 20% CCM based diet with enzyme supplementation had the best FCR value (2.18). The haematological parameters were not significantly influenced (P>0.05) by the diets except for lymphocytes and heterophil count with the highest lymphocytes value in T2 (68.00%) and the lowest value in T5(53.67 %). Birds on T5 had significantly (P<0.05) highest heterophil value (40.67%). The serum biochemical indices were not significantly influenced (P>0.05) by the diets except for aspartate aminotransferase. However, values obtained in this study fell within the normal range recommended for healthy broiler chicken. Based on this result, it can be concluded that CCM with enzyme supplementation can be incorporated into broiler diet up to 20% without any detrimental effect on their performance and blood profile.

A series of experiments was conducted to determine the nutritive value of wheat screenings, bakery by-products and wheat mill run used by the feed industry in Canada and to investigate the effect of enzyme supplementation on available energy content, nutrient digestibility and broiler chicken growth performance. Broiler chicken performance (2-wk growth trial) was compared using a wheat/soybean meal-based control diet and diets substituted with wheat by-products (wheat screenings, 200 g kg-1; bakery by-products or mill run, 100 g kg-1). In addition, diets containing one sample of each of the by-products were fed to broiler chickens with enzyme supplementation (Superzyme W®). Chicken performance was not affected by dietary substitution of wheat by-products for wheat as values for control, wheat screenings (three samples), bakery by-products (two samples) and mill run (one sample) were similar for body weight gain (514, 520, 515, 500 g bird-1) and for feed to gain ratio (1.52, 1.52, 1.52, 1.50), respectively. Response to enzyme supplementation was highest for wheat screenings showing a statistically significant (P ≤ 0.05) improvement in body weight gain (523 vs. 548 g bird-1) and feed to gain ratio (1.54 vs. 1.47). To further substantiate the importance of enzyme supplementation, a long-term production trial with broiler chickens was conducted. Five replicate pens of 60 birds per treatment were used in the starter (21 d) and grower (16 d) phases of the experiment consisting of three treatments: positive control (PC) (wheat/soybean meal/fish meal), negative control (NC) (wheat/wheat screenings/barley/soybean/ canola meal) and NC + Enzyme (Superzyme W®). In comparison to PC, the NC diet contained 5% less metabolizable energy, 8–10% less crude protein, amino acids and calcium and 25% less available phosphorus. Body weight gain and feed conversion ratio averaged 2.14, 2.10, 2.17 kg bird-1 and 1.68, 1.76, 1.66 for PC, NC and NC + Enzyme, respectively. A significant (P < 0.05) improvement in broiler chicken performance with enzyme supplementation was further substantiated by the same magnitude of difference in dry matter (71.2, 68.7, 75.1%), starch (92.5, 90.3, 95.6%), non-starch poly saccharides (NSP) (4.8, 15.0, 36.1%), energy (AME) (12.37, 11.83, 12.84 MJ kg-1) and phytate (44.3, 37.5, 69.5%) digestibilities. It is evident from this study that the use of wheat by-products in concert with an effective enzyme supplement in broiler chicken diets will allow for optimum growth performance.
