“…Despite numerous scientific investigations, no alternative grain to corn has yet been identified. Wheat, barley, and rye are well docnniented to cause detrimental effects on growth, intestinal digesta viscosity, nntrient digestibility, morphological development, and microbial populations in chickens (Ahnirall et al, 1995;Crouch et al, 1997;Langhout et al, 1999;Mathlouthi et al, 2002;Lázaro et al, 2003). But, recently, we reported that a new hybrid Canadian pearl millet {Pennisetum glaucum) variety (CGPMH-90, Agriculture Environmental Renewal Canada Inc., Delhi, Ontario, Canada) can potentially replace corn in broiler diets and lead to substantial improvements in BW and feed efficiency without affecting any intestinal traits (Baurhoo et al, 2011).…”

An experiment was conducted to compare a commercial corn-soybean meal diet with a pearl millet diet containing less soybean meal (-27%), alone or in combination with exogenous enzymes, on growth performance, jejunal villus development, ileal CP, and AA digestibility, and cecal microbial populations in broilers. One hundred sixty 1-d-old male Ross 508 broilers (5/cage) were randomly allocated to one of the following dietary treatments: 1) a standard corn-soybean meal control diet (CTL); 2) a pearl millet-soybean meal diet (PM); 3) CTL + exogenous enzymes (CE); and 4) PM + exogenous enzymes (PE) with 8 replicate cages/treatment. The PM and PE diets contained less soybean meal because of greater CP and AA contents of pearl millet. All diets were isonitrogenous and isocaloric. Body weight and feed intake were recorded weekly over 35 d. At d 21 and 35, 8 broilers per treatment were euthanized for sample collection and analyses. Gain-to-feed was greater (P < 0.01) for pearl millet- than corn-based diets. Apparent ileal digestibility (AID) of CP and most AA was similar between corn-based and pearl millet-based diets, and enzyme supplementation improved AID of CP (P < 0.01) and most AA at both d 21 and 35. However, for AID of some AA at d 21, the response to enzyme supplementation was less pronounced in broilers fed pearl millet-based diets than those fed corn-based diets (grain × enzyme, P ≤ 0.05). The villus was longer (P < 0.01) in broilers fed PM and PE than CTL and CE at d 35. Similarly, at d 35, lactobacilli loads were greater (P < 0.01) in broilers fed PM and PE than CTL and CE. It is concluded that, in comparison with corn, broiler diets formulated with pearl millet require less soybean meal and can be used to improve growth performance traits, intestinal lactobacilli populations, and villus development, whereas enzyme supplementation increases AID of CP and AA.

“…Wheat-based diets fed to growing broilers may result in similar or lower performances compared with maize-based diets, depending on the source of wheat (Crouch et al, 1997). This variation in responses to different wheats is probably related to variation in the metabolisable energy (ME) value of wheats given to broiler chickens (Mollah et al, 1983;Rogel et al, 1987;Nicol et al, 1993).…”

1. Three maize diets containing 0, 1 or 3 g of guar gum per kg and 2 wheat diets were given to male broiler chickens for measurements of growth performance and nutrient digestibility. 2. The intestinal viscosities found with wheat diets were within the range of those observed with the 3 maize diets. The correlations between in vivo and in vitro viscosities were higher with real than with potential applied viscosity. 3. The gain:food ratio decreased (P < 0.05) with the addition of 3 g guar gum/kg. The mean gain:food ratio observed for wheat diets was lower (P = 0.007) than the mean value found for the 3 maize diets. 4. The negative effects of increased intestinal viscosity due to guar gum addition on nutrient digestibility were highest for lipids and lowest for starch. 5. Wheat diets resulted in much lower (P < 0.001) starch apparent digestibility compared to maize diets with added guar gum despite similar mean intestinal viscosities in the 2 groups of diets. Apparent lipid digestibility with wheat diets was lower (P < 0.01) than the value predicted from intestinal viscosity, the predictive model having been calculated with the guar gum added maize diets. Apparent protein digestibility did not differ between wheat diets and guar gum added maize diets. 6. It was concluded that the low apparent digestibilities of starch and lipid observed with wheats could not be attributed only to intestinal viscosity and that other factors appear to be implicated in the low digestibilities observed with the wheat samples tested in the present experiment.

Two experiments were conducted to study the effect of autoclaving and heat processing (HP) and enzyme supplementation on wheat nutritive value for quails. In the first experiment, 72 male quails (13 weeks) were used to determine apparent metobalisable energy corrected for nitrogen (AMEn) of wheat samples. In the second experiment, 720 seven-day-old as-hatched Japanese quail were randomly assigned to a 3 )3 factorial design. Factors include three processing methods (untreated, autoclaving and HP) and three levels of enzyme (0, 0.25 and 0.5 g/kg). Each treatment group consisted of 4 replicates of 20 birds. According to the results, the total and insoluble none starch polysaccharides (NSP) and insoluble to soluble NSP ratio increased by processing (PB0.01) and also total and insoluble b-glucan increased by processing (PB0.01). The amount of AME, AMEn, gross energy efficiency and dry matter digestibility of wheat has significantly increased by autoclaving (P B0.05). Quails performance was increased by wheat autoclaving (PB0.05). However, wheat dry heat processing had no significant effect on performance. Adding enzyme to diet significantly improved quails performance. By autoclaving wheat, carcass and breast weight significantly increased (PB0.05). Adding enzyme to diet significantly increased breast and thigh weight (P B0.05). In conclusion, we can use autoclaving, in spite of enzyme supplementation, to improve growth rate and feed conversion ratio of growing quail fed diets based on wheat.
