was evident when chicks were given the wheat diet. In the second experiment, rhe addition of Roxazyme@ G to diets containing hulGss barley (0.1 g kg-1) and rye 14.0 g tg-tl improved feed consumption (8 and 16%, respectively), weight gain(21 and35%, respectivelyf and feed-to-gain ratios (i 1 and, l4Vo , respectively). Relative gizzard weights of birds fed the rye diet were reduced by 18 % when enzyme was added to this diet. In the third experiment, replacing all the wheat with hulless barley, naked oats or rye in diets for young pullets had no effect on overall performance during a i2-wk laying trial. Vent feather soilage increased with the incorporation ofnaked oats and rye. Enzyme supplementation had a beneficial effect on weight gain and feed intake but not on egg production, initiaiegg weight, average egg weight, egg specific gravity, Haugh unit score, and mortality.

“…Bird weights (on a pen basis) and feed intake (FI) were measured at 0, 14, and 25 d. The FCR was calculated from body weight gain (BWG) and FI and was corrected for mortality. The bioassays followed procedures similar to those described by Scott et al (1998a). For each bioassay, a total of 240 male broilers (Ross × Arbor Acres) were used.…”

Rafuse, J. L., Silversides, F. G., Bedford, M. R. and Simmins, P. H. 2005. Effect of cultivar and enzyme supplementation on nutrient availability and performance of broilers fed Maritime Canadian wheat. Can. J. Anim. Sci. 85: 493-499. The feeding value of wheat is affected by the content of soluble non-starch polysaccharides (NSP), which varies among cultivars and the environment in which they are grown. Dietary enzymes can reduce the negative effects of NSP and improve the apparent metabolizable energy (AME) content of the wheat. This study examined differences in feeding value of four wheat cultivars grown in 2 crop years in the Maritime provinces of Canada and the need for enzymes. In a growth trial, diets containing one of the Maritime wheats or corn were fed with or without commercial enzymes containing, for wheat-based diets a mixture of xylanase and protease, and for corn-based diets a mixture of xylanase, protease, and amylase. In a broiler chick bioassay, diets containing 80% wheat were fed with or without a commercial enzyme with xylanase and protease activities. Enzymes significantly lowered body weight gain of birds fed Walton wheat in the second year, and improved the grower feed conversion ratio of birds fed Norboro wheat. Enzyme supplementation significantly improved apparent metabolizable energy and digestibility of crude protein. The AME content did not appear to be a direct indicator of performance. There were significant differences in AME content among the wheat samples. Enzymes generally did not improve performance in this study, possibly due to the relatively low in vitro viscosity values of these samples. Maritime wheats were equal or compared favourably with the sample of wheat from Western Canada and to locally obtained corn. Mots clés: Blé, rendement des poulets de chair, énergie métabolisable apparente, enzymeThe feeding value of wheat is adversely influenced by the presence of anti-nutritional factors in the form of soluble non-starch polysaccharides (NSP). In the gastrointestinal tract of broilers, a portion of the NSP becomes soluble and results in sticky droppings, reduced uptake of nutrients, and decreased weight gain.

“…Anti-nutritional activity is also believed to be responsible for the relatively low apparent metabolisable energy (AME) values (AME < 13 MJ kg" 1 DM) recorded for some Australian wheats (Mollah et al 1983) and UK wheats (Wiseman et al 1994). The cause has been attributed to the high levels (850 g kg" 1 DM, Wiseman & Inborr 1990) of arabinoxylans (pentosans) in the total wheat fibre fraction (Choct & Annison 1992).…”

The effect of a commercial feed enzyme complex on the performance of meat-chickens fed barley-and wheat/maize-based pelleted diets was investigated using a variety of barley whose true metabolisable energy (TME) was found to be responsive to enzyme addition and a feed grade wheat and maize. Bioassays for TME of three varieties of barley and of wheat and maize, showed Fleet barley to be responsive to enzyme addition at 100 ppm (P < 0.01) and 200 ppm (P < 0.05). The liveweight, liveweight gain, and feed conversion ratio of meat-chickens receiving Fleet barley-based diets supplemented with an enzyme complex (Roxazyme G) at either 0, 100, or 150 ppm or a wheat/maize-based dietary control with no enzyme inclusion (W/M), was significantly improved by enzyme addition.Enzyme supplementation at 100 and 150 ppm of a W/M-based control diet had no significant effect on the performance of meat-chickens grown to 39 days.Use of feed enzymes may permit greater use of barley in meat-chicken diets and is a strategy capable of conferring performance-enhancing effects in appropriate circumstances.
