Our objectives were to determine the effects of hybrid rye inclusion on finishing steer performance and carcass characteristics, and to estimate net energy (NE) value.
Study Description
Predominately Angus steers (n = 240, initial shrunk bodyweight [BW] = 891 ± 40.8 pounds) were used in 117-d finishing experiment. Hybrid rye was used to replace either one-third, two-thirds, or 100% of dry-rolled corn (DRC) resulting in four treatments: [DRC:Rye, DM basis (60:0), (40:20), (20:40), and (0:60)] with six pens per treatment and 10 steers/pen. Performance adjusted NE values were calculated from performance and carcass data. Replacing DRC with rye linearly decreased (P ≤ 0.01) carcass-adjusted final BW, ADG, DMI and G:F. Feeding rye linearly decreased HCW and ribeye area (P ≤ 0.04). Liver abscess scores and carcass grades were unaffected by treatment (P ≥ 0.09). Estimated NEm and NEg values for rye when included at 60% of the diet DM were 0.86 and 0.57 Mcal/lb, respectively.
