A feedlot growth-performance trial and a metabolism trial were conducted to evaluate a dose response to ardacin (a glycopeptide antibiotic). Treatments consisted of an 88% concentrate finishing diet supplemented to contain (DM basis) 0, 8.25, 16.5., or 33 mg ardacin/kg. The growth-performance trial (129 d) involved 120 heifers and 120 steers in a randomized complete block design. There were no interactions (P less than .10) between sex and response to ardacin. Average daily gain increased (P…

Effects of ardacin supplementation on rumen fermentation and protein degradability in steers
TLDR
It is concluded that ardacin altered rumen fermentation in a dose-dependant manner in a direction suggestive of improved growth and/or feed conversion efficiency and may increase the quantity of dietary protein supplied to the small intestine.
Effects of ardacin supplementation on rumen fermentation and protein degradability in steers
Ardacin for steers grazing endophyte-free fescue pasture: effects on live weight gain, forage intake, nitrogen and fiber digestion, ruminal fluid kinetics, ruminal fermentation, and serum hormones and metabolites.
TLDR
Growth and digestion studies were conducted to evaluate the use of ardacin as a feedgrade antibiotic for enhancing digestive function and growth in grazing steers and the effects of the same supplements used in Exp. 1 on ruminal fermentation and digestion.
Avoparcin and monensin effects on the digestion of nutrients in dairy cows fed a mixed diet
An in vivo study was carried out to evaluate the effect of avoparcin on fiber, starch and nitrogen (N) digestion compared with monensin. Three dairy lactating cows with ruminal, duodenal and ileal…
Effect of Ionophore Enriched Cold Processed Mineral Block Supplemented with Urea Molasses on Rumen Fermentation and Microbial Growth in Crossbred Cattle
TLDR
Feeding of UMMB and monensin in diet affected the rumen fermentation pattern towards propionate production, slower release of ammonia and reduction in methanogenic bacteria in the rumens, resulting in lower A:P ratio.
IMPACT OF GRAIN PROCESSING AND QUALITY ON HOLSTEIN STEER PERFORMANCE
The topic of grain processing for feeding ruminants has been reviewed extensively (Nocek and Tamminga, 1991; Huntington, 1997; Theurer et al., 1999; Rowe et al., 1999; Harmon and McLeod, 2001, 2005;…
Economic Analysis of Pharmaceutical Technologies in Modern Beef Production
Cattle production is the largest single agricultural sector in the U.S. with cash receipts of $49.2 billion in 2005. Like the rest of agriculture cattle producers have adopted efficiency and quality…
SITE AND EXTENT OF STARCH DIGESTION BY CATTLE
Grains are fed to livestock primarily to supply energy, and the major energy source in cereal grains is starch. For maximum starch digestion, corn and sorghum grain must be processed. For…

TLDR
Considering the evolution in cattle types, management and marketing conditions, and changes in diet ingredients and processing that have occurred during the past 50 yr, updating by a skilled committee to correct certain anomalies within the CNES as currently being applied seems appropriate.
