“…Although only small number of wheat samples was studied in this experiment, the results confirm the importance of research on wheat processing to better understand the interactions between processing and wheat chemical and quality characteristics when evaluating its feeding value for broilers. The proximate nutrient, polysaccharide and GE contents, and EH of the experimental wheat samples were in a similar range to those measured in other studies (Rose et al, 2001;Pirgozliev et al, 2003;Carre et al, 2005).…”

“…In accord with previous reports with mash (Scott et al, 1998;Rose et al, 2001;Steenfeldt, 2001;Pirgozliev et al, 2003) and pelleted (Amerah et al, 2009) wheat-based diets, in the present study birds were fed wheat that had high starch and protein contents, and relatively hard endosperm, and had an improved FI and WG. The feed form by wheattype interactions observed in this study shows that milling wheat instead of feed wheat in pelleted diets results in improved NR and G : F ratio in broiler chickens.…”

“…However, there is inconsistence in the literature as some of the authors report responses on growth performance and nutrient availability to mash diets (Scott et al, 1998;Rose et al, 2001;Steenfeldt, 2001;Pirgozliev et al, 2003), others reported responses to pelleted diets (Wiseman et al, 2001;Carre et al, 2005). However, there is a lack of information on a direct comparison of feeding value of wheat with different chemical and quality characteristics, and the dietary form, thus more research is needed.…”

Experimental comparisons of the nutritional value of different wheat cultivars commonly use feeds in meal form even though the largescale broiler producers use steam pelleted feeds. The aim of this experiment was to examine the effect of steam pelleting on the performance, dietary N-corrected apparent metabolisable energy (AMEn), total tract dry matter retention (DMR), nitrogen retention (NR) and fat digestibility (FD) coefficients, and digestive tract development of broilers fed four different wheat samples in complete diets. Four European wheat samples, with different chemical composition and endosperm characteristics, were used in a broiler experiment. The wheat samples were milled through a 5 mm screen and four basal feeds containing 670 g/kg of each selected wheat sample were mixed. The basal feeds were then split into two batches and one of them was steam pelleted resulting in eight experimental diets. Each diet was fed ad libitum to eight pens of two male Ross 308 broilers from 10 to 24 days of age. Feeding pelleted diets improved ( P < 0.001) feed intake and weight gain, and daily water intake of the birds. Pelleting also improved dietary AMEn and FD ( P < 0.001) and DMR ( P < 0.05). An interaction ( P < 0.05) was observed between wheat samples and steam pelleting for NR. Steam pelleting improved ( P < 0.05) NR in the wheat sample with high starch and protein and hard endosperm but not in the rest of the wheat samples. Similar interactions ( P < 0.05) were also observed between wheat sample and steam pelleting for gain to feed (G : F) and water to feed (W : F) ratios. Pelleting improved G : F ratio the greatest in the wheat sample with high starch and protein and hard endosperm. Feeding the same wheat sample also decreased ( P < 0.05) W : F but only in the mash diets. Regardless of the wheat sample the values of dietary AMEn did not differ ( P > 0.05). Feeding different wheat types and pelleting did not ( P > 0.05) change the development of the gastrointestinal tract of the birds. The study showed that there were differences between four wheat samples when they were fed in pelleted complete feed, but no differences were observed when fed in mash form complete diets. Research on the interaction between pelleting and wheat chemical and quality characteristics is warranted.

“…Growing season has an effect on specific weight, endosperm hardness, content of CP and starch and total, insoluble and soluble NSP content of wheat (Metayer et al, 1993;Waldron et al, 1994;Scott et al, 1998;Rose et al, 2001;George and McCracken, 2003;Kim et al, 2003;Pirgozliev et al, 2003). Nevertheless, most of those effects were mainly explained by differences between environmental conditions nested within the growing season.…”

“…Dusel et al, (1997) reported a positive correlation between annual precipitation and extract viscosity of wheat, while precipitation during the growing season was negatively correlated with extract viscosity of wheat (r = -0.55, P < 0.05). Rainy conditions just before harvest were related to low specific weight, endosperm hardness and CP content of wheat due to a high proportion of sprouted grains (Metayer et al, 1993;Kruger, 1994;Rose et al, 2001).…”

Wheat is a common raw material used to provide energy in broiler diets. Its apparent metabolisable energy and its influence on broiler performance varies between wheat samples. Reasons for that variability can be classified as intrinsic (variety, chemical composition) and extrinsic factors (growing conditions, storage, etc.), both of which affect nutrient digestibility and availability. However, these factors are not always considered when formulating the diets for broiler chickens. Moreover, research through the years has questioned the relation between wheat AME and animal performance. This review aims to describe factors that influence the observed variability in wheat nutritive value for broiler chickens by considering origin (variety, growing conditions and post-harvest storage), chemical composition of the grain (carbohydrates and protein) and the broiler chicken.
