Supplementation Of Methionine Or Choline Did Not Improve Health Or Growth Performance In High-Risk, Newly Received Beef Heifers, Madeline S. Grant, Dale A. Blasi, Evan C. Titgemeyer
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 …
Effects Of Guanidinoacetic Acid, Creatine, And Choline On Protein Deposition And Creatine Status In Growing Cattle, M. S. Grant, M. D. Miesner, E. C. Titgemeyer
Effects Of Guanidinoacetic Acid, Creatine, And Choline On Protein Deposition And Creatine Status In Growing Cattle, M. S. Grant, M. D. Miesner, E. C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Objective:This study was conducted to evaluate effects of guanidinoacetic acid and creatine supplementation in the presence or absence of supplemental choline on body creatine status and lean tissue growth.
Study Description:Six ruminally-cannulated Holstein steers (321 lb) were utilized in an experiment consisting of six 10-day periods, where each steer received one of six treatments in each period. Treatments were abomasal infusion of a saline solution (control), 15 g/day guanidinoacetic acid, or 16.8 g/day creatine, in combination with 0 or 5 g/day choline, with all treatment combinations represented. Complete collection of urine and feces was conducted to calculate nitrogen …

Effects Of Choline On Neutrophil Function And Inflammation In Growing Cattle With Modulated Methyl Group Status, M. S. Grant, H. D. Aufdemberge, B. J. Bradford, L. K. Mamedova, E. C. Titgemeyer
Kansas Agricultural Experiment Station Research Reports
Objective:This study was conducted to evaluate the effects of supplemental choline in combination with guanidinoacetic acid or creatine on immune cell function and inflammation in growing cattle.
Study Description:Six ruminally-cannulated Holstein steers (321 lb) were utilized in an experiment where each steer received each of six treatments. Treatments were given via abomasal infusion of a 0 or 5 g/day of supplemental choline, and either a saline solution (control); 15 g/day guanidinoacetic acid; or 16.8 g/day of creatine, with all treatment combinations represented. Steers were fed a corn-based diet. Blood was collected during each period to measure neutrophil function, …
