“…However, that study used a continuous inclusion of high-lipid high-fibre byproduct pellets throughout the finishing phase. Our studies support that of Górka et al (2013), where steers fed the highlipid high-fibre byproduct pellets for 147 or 120 d had reduced G:F relative to steers fed a barley-based finishing diet. However, feeding the high-lipid high-fibre byproduct pellets during the latter part of finishing period (49 d in Study 1 and 60 d in Study 2) did not negatively influence DMI, G:F, ADG, or carcass characteristics.…”

“…Previous studies have demonstrated that G:F may be reduced with the inclusion of high-lipid high-fibre byproduct pellets in diets for finishing steers (Górka et al 2013). However, that study used a continuous inclusion of high-lipid high-fibre byproduct pellets throughout the finishing phase.…”

“…The composition of the high-lipid high-fibre byproduct pellets and diets are listed in Table 1. The high-lipid byproduct pellets were produced at West Central Pelleting Ltd. (Wilkie, SK, Canada) and were similar to that reported by Górka et al (2013). The diets were formulated to be iso-nitrogenous and iso-caloric and to target an ADG of 1.8 kg d…”

“…As a substitute for cereal grain and in order to maintain caloric density, byproduct pellets often depend on byproducts from the oilseed industry as a cheaper source of energy substrate (Górka et al 2013). Hence the incorporation of byproducts from the oilseed industry (e.g., off-grade canola) can be associated with a partial shift in the dietary energy source from starch to lipid.…”

“…Most previous studies have investigated dietary byproduct inclusion in isolation rather than utilizing a combination of byproducts. However, a few recent studies have evaluated the use of strategically blended byproduct pellets that incorporate the benefits of individual byproducts while avoiding overfeeding of individual nutrients as it occurs with single byproduct inclusion strategies (Górka et al 2013;Zenobi et al 2014). The use of strategically blended byproduct pellets also minimizes difficulty associated with handling multiple ingredients on farm and increases feed density.…”

Two studies were conducted to evaluate the provision of high-lipid high-fibre byproduct pellets when used as a partial replacement (60% in Study 1 and 30% in Study 2; HLP) for barley grain and canola meal in finishing diets (BAR). The HLP was fed for the last 49, 98, or 147 d (HLP49, HLP98, and HLP147, respectively) in Study 1, and for the last 60 or 120 d in Study 2 (HLP60 and HLP120, respectively) or the last 60 d with additional canola oil (HLP60CO). The statistical model included the fixed effects of diet, period, and the interaction. Steers fed BAR147 had the greatest average daily gain (ADG) (P < 0.01) and G:F (P = 0.01). The HLP147 had the greatest dry matter intake (DMI) during the first 49 d but least during the last 49 d of the finishing phase (treatment × period; P < 0.01). Hot carcass weight for BAR147 and HLP49 were the heaviest (P = 0.04). In Study 2, DMI and ADG were not affected (P > 0.05), but hot carcass weight was greater for BAR120 and HLP60 than HLP120 and HLP60CO. Inclusion of high-fibre high-lipid byproduct pellets in the latter part of the finishing period may improve carcass yield grade without affecting ADG and G:F.

High-fibre high-lipid by-product pellets containing calcium oxide-treated oat hulls as a partial replacement for barley grain in finishing diets for beef cattle

et al. 2018

Two studies were conducted to evaluate the effects of treating oat hulls with calcium oxide (CaO) prior to inclusion in a high-lipid by-product pellet (HLP) on dry matter intake (DMI), ruminal fermentation, and total-tract digestibility (Study 1) and growth performance (Study 2). In Study 1, six ruminally cannulated heifers were used in a replicated 3 × 3 Latin square design. Study 2 used 210 steers in 21 pens in a 113 d finishing study. Dietary treatments for both studies included a barley-based control diet (CON), a diet where HLP partially replaced barley grain (NT-HLP), and a diet where HLP contained oat hulls treated with 7.5% CaO [dry matter (DM) basis; CaO-HLP]. For Study 1, DMI and ruminal pH were not affected. Apparent total-tract digestibility of DM and organic matter (OM) were greater (P < 0.05) for CON than NT-HLP and CaO-HLP. In Study 2, final body weight tended to be greater for NT-HLP and CaO-HLP than CON (P = 0.065). For CaO-HLP and NT-HLP, DMI was greater than CON (P < 0.01), but average daily gain (ADG) (2.0 kg d−1) and gain:feed (G:F) (0.16 kg kg−1) were not different. Thus, HLP can partially replace barley grain in finishing diets without negatively affecting ruminal fermentation or growth performance, but treatment with CaO has no effect.

This study was designed to evaluate dry matter intake (DMI), ruminal fermentation, ruminal digesta outflow, omasal flow of N constituents, and ruminal and total-tract digestibility in response to increasing dietary lipid content derived from high-lipid byproduct-based pellets for finishing beef cattle. Five ruminally cannulated heifers were used in a 5 × 5 Latin square design. Dietary treatments were iso-nitrogenous with increasing ether extract (EE) concentrations resulting in dietary concentrations of 3.5, 4.2, 4.7, 5.1 and 5.9% of dry matter. Periods were 28 d in duration with the first 19 d used for dietary adaptation and the last 9 d for sample and data collection. Dry matter intake, ruminal pH, omasal flow of N constituents, and SCFA concentrations were not affected by increasing dietary EE content (P ≥ 0.10). Increasing dietary EE content increased outflow of EE from the rumen (P < 0.001). Apparent ruminal and total-tract digestibility of EE increased linearly (P ≤ 0.03) with increasing dietary EE levels. Results indicate that increasing dietary EE content from 3.5 up to 5.9% of DM by including high-lipid byproduct-based pellets does not alter site of nutrient digestibility with no negative effects on nutrient intake, ruminal fermentation, or apparent ruminal and total-tract digestibility.
