Kansas Agricultural Experiment Station Research Reports
Objective:This study was conducted to determine if supplemental methionine or choline improves health or growth performance in high-risk, newly received beef heifers.
Study Description:In a 3-year experiment, 1,440 beef heifers (480 per year; 493 lb initial weight; Tennessee origin) were received in 15 truckloads (five per year) in October of 2020, 2021, and 2022. Heifers were limit-fed in 60-day receiving trials to evaluate the effects of supplemental methionine or choline on health and growth performance. Cattle received one of five treatments: control (no added methionine or choline); 5 or 15 g/day available methionine (8.33 or 25 g/day Smartamine …
