Objective: This study was conducted to evaluate the ability of supplemental methionine to improve health, inflammation status, and performance of receiving cattle.

Study Description: A group of 384 crossbred heifers (initial weight 489 lb) of Tennessee origin were used in a 45-day receiving trial with limit-feeding to evaluate the effects of supplemental methionine (Smartamine M; Adisseo, Alpharetta, GA) on health, inflammation, and performance. Cattle received either 0 (control) or 10 grams/day Smartamine M, a ruminally protected methionine product. Plasma haptoglobin levels measured on days 0, 14, and 45 were used as a biomarker of inflammation.

The Bottom Line: Supplemental ...

Effects Of Guanidinoacetic Acid On Lean Growth And Methionine Flux In Cattle, M. Ardalan, M. D. Miesner, C. D. Reinhardt, D. U. Thomson, C. K. Armendariz, E. C. Titgemeyer

Kansas Agricultural Experiment Station Research Reports

Objective: To evaluate the effect of supplementing guanidinoacetic acid in the presence or absence of L-methionine on nitrogen retention (lean tissue growth) when cattle were purposefully maintained under conditions of a methionine deficiency.

Study Description: Seven ruminally-cannulated Holstein steers (355 lb) were used in an experiment where each steer received each of six treatments. Treatments were abomasal infusion of 0 or 6 g/day methionine, and 0, 7.5, or 15 g/day guanidinoacetic acid, with all combinations represented. Energy was supplied by ruminal infusion of volatile fatty acids and abomasal infusion of glucose. All essential amino acids except methionine ...

Sensory Evaluation From Asian Consumers Of Six Different Beef Shank Cuts, W. Wu, E. A. Rice, B. A. Olson, T. G. O'Quinn, T. A. Houser, E. A. Boyle, M. D. Chao

Kansas Agricultural Experiment Station Research Reports

Objective: The objective of this study was to evaluate factors affecting Asian consumers’ purchasing decisions and eating preferences of six different beef shank cuts.

Study Description: Six different beef shank cuts, three from the forequarter [biceps brachii (shank A); a combination of deep digital flexor and flexor digitorum superficialis (shank B); extensor carpi radialis (shank C)], and three from the hindquarter [flexor digitorum superficialis (shank D); deep digital flexor (shank E); and a combination of long digital extensor, medial digital extensor and peroneus tertius (shank F)] were collected from 12 U.S. Department of Agriculture Low Choice beef carcasses. Shanks ...
