“…However, these distributions were altered to a greater extent when HP wheat was TR as compared with LP wheat. Similar responses in particle size distribution between hard and soft kernel wheat were observed by Saleem et al (2022), where tempering altered these distributions to a greater extent with hard compared with soft wheat. Harder wheat types are typically conditioned prior to rolling for a longer period of time than soft wheat (Fang and Campbell 2003;Dziki and Laskowski 2005), as the continuous protein matrix of hard wheat absorbs moisture at a slower rate than soft wheat.…”

“…The softer endosperm texture of LP wheat is derived from a discontinuous protein matrix containing air spaces, resulting in a lower density and broader distribution of protein and starch constituents (Anjum and Walker 1991). This contrasting characteristics of HP and LP wheat grain used in this study are similar to Saleem et al (2022), where more large particles as a result of processing were generated from LP-DR wheat compared to HP-DR wheat. The greater distribution of larger particles from LP-DR wheat are the result of starch granules being separated more easily from the discontinuous protein matrices during processing, as the air spaces function as regions where stress forces concentrate and facilitate breakage (Fang and Campbell 2000).…”

“…For example, hard kernelled grains (i.e. high protein wheat) require more force to crack, causing starch granules to shatter into fine particles that can increase the risk of acidosis (Saleem et al, 2022). Tempering hard kernels prior to rolling can soften the endosperm and reduce fracturing, generating more consistent particles that can reduce this risk (Dziki and Laskowski, 2005).…”

This study assessed the impact of dry (DR) vs. temper rolled (TR) and low (13%, LP) vs. high protein (18%, HP) wheat on ruminal fermentation, growth, and liver abscesses in feedlot cattle. Crossbred Angus steers (302 ± 34 kg; n=160; 24 ruminally cannulated) were used in a backgrounding (BG) to finishing (FN) trial. The BG diet consisted of 60% barley silage, 35% wheat, and 5% supplement, and the FN diet contained 10% barley silage, 85% wheat, and 5% supplement (DM basis). Four transition (TN) diets were used to adapt cattle to the FN diet. A numerical increase in large particles and reduction in small particles occurred when both HP and LP wheat were TR, with this response being greater for HP wheat. Steers experienced lower (P≤0.03) ruminal pH with HP-DR and LP-TR than HP-TR wheat during TN. Steers fed HP wheat BG diets tended to exhibit greater (P ≤ 0.09) G:F and NEg than steers fed LP wheat. Greater (P=0.01) ADG were exhibited by FN steers fed LP wheat. Liver abscesses were more (P<0.001) severe with HP wheat. While HP wheat improved the growth of BG cattle, it increased the severity of liver abscesses during FN.

This study was designed to assess the impacts of a mixture of deoxynivalenol (DON) and ergot alkaloids (EAs) on growth performance, rumen function, blood parameters, and carcass traits of feedlot cattle. Forty steers (450 ± 6.0 kg) were stratified by weight and randomly allocated to 1 of 4 treatments; control-low (CON-L), control-high (CON-H) which contained low or high wheat screenings that lacked mycotoxins at the same level as the mycotoxin-low (MYC-L; 5.0 mg/kg DON, 2.1 mg/kg EA), and mycotoxin-high (MYC-H: 10 mg/kg DON, 4.2 mg/kg EA) diets that included wheat screening with mycotoxins. Steers were housed in individual pens for a 112-day finishing trial. Intake was 24.8% lower (P < 0.001) for MYC steers compared to CON steers. As a result, average daily gains of MYC steers were 42.1% lower (P < 0.001) than CON steers. Gain to feed ratio was also lower (P < 0.001) for MYC steers compared to CON steers. Platelets, alanine aminotransferase, globulins, and blood urea nitrogen were lower (P ≤ 0.008), and lymphocytes, glutathione peroxidase activity (GPx), and interleukin-10 (IL-10) were elevated (P ≤ 0.002) in MYC steers compared to CON steers. Hot carcass weights and backfat thickness were reduced (P < 0.001) in MYC steers, resulting in leaner (P < 0.001) carcasses and higher (P < 0.007) meat yield compared to CON steers. Results suggest that a mixture of DON and EAs negatively impacted health, performance, and carcass traits of feedlot steers, with the majority of this response likely attributable to EAs. However, more research is needed to distinguish the relative contribution of each mycotoxin to the specific responses observed.
