What does this research mean for the field?

Hybrid rye has a similar net energy value to dry-rolled corn and can completely replace it in high-forage backgrounding diets for growing beef steers without compromising growth performance. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To evaluate the effects of replacing dry-rolled corn with rolled or ground hybrid rye on growth performance and net energy values in diets for backgrounding beef steers.

Overview

Randomized trial reveals equivalent growth performance and net energy between hybrid rye and corn in growing beef steers, indicating rye is an effective grain replacement.

Key Points

To evaluate the effects of replacing dry-rolled corn with rolled or ground hybrid rye on growth performance and net energy values in diets for backgrounding beef steers.
Conducted a 63-d feedlot experiment using a randomized complete block design with 150 crossbred Bos taurus beef steers (initial shrunk body weight = 260 ± 22.2 kg; 5 pens/treatment, 10 steers/pen).
Assigned cattle to three dietary treatments where dry-rolled corn was fully replaced by either rolled hybrid rye (geometric mean particle diameter of 1,780 µm) or ground hybrid rye (731 µm).
Calculated performance-adjusted net energy values for maintenance and gain using average daily gain, dry matter intake, and the replacement technique.
Observed no differences between corn and rye diets (P ≥ 0.10) for ending body weight, body weight gain, average daily gain, dry matter intake, gain-to-feed ratio, or performance-adjusted net energy.
Steers fed ground rye tended to exhibit greater body weight gain (P ≤ 0.07) and average daily gain (P ≤ 0.06) compared to those fed rolled rye, with no differences in dry matter intake or feed efficiency.
Calculated replacement net energy for maintenance and gain at 1.91 and 1.25 Mcal/kg for rolled rye versus 2.29 and 1.58 Mcal/kg for ground rye, indicating ground rye provides comparable energy to corn.
