Effects of live cultures of Lactobacillus acidophilus (strains NP45 and NP51) and Propionibacterium freudenreichii on performance, carcass, and intestinal characteristics, and Escherichia coli strain O157 shedding of finishing beef steers.
N. A. Elam,J F Gleghorn,J. D. Rivera,M. L. Galyean,P. J. Defoor,Mindy M. Brashears,S. M. Younts-Dahl +6 more
TL;DR: Overall, data indicate that live cultures of LA plus PF did not greatly affect feedlot performance and carcass characteristics and some of the DFM used decreased fecal EC shedding, which might be related to the results for ileal lamina propria thickness.

Effects of crude protein concentration and degradability on performance, carcass characteristics, and serum urea nitrogen concentrations in finishing beef steers.
TL;DR: Results indicate that increasing CP concentrations from 11.5 to 13% slightly increased ADG and carcass-adjusted ADG, whereas increasing the proportion of supplemental urea increased carcass to a common dressing percent within location and increased HCW, LM area, and dressing percent.

Effects of a dietary Aspergillus oryzae extract containing α-amylase activity on performance and carcass characteristics of finishing beef cattle
J.M. Tricarico,M D Abney,M. L. Galyean,J. D. Rivera,K. C. Hanson,Kyle R. McLeod,David L. Harmon +6 more
TL;DR: It is concluded that dietary alpha-amylase supplementation of finishing beef diets may result in increased ADG through increased DMI under certain dietary conditions and that further research is warranted to explain its mode of action and interactions with dietary ingredients.

Galyean Appreciation Club Review: revisiting nutrition and health of newly received cattle—what have we learned in the last 15 years?
TL;DR: A review of the literature related to the health and management of newly received cattle published since a previous review by Duff and Galyean (2007) can be found in this paper , where the authors present a comprehensive review.
Effects of copper and zinc source on performance and humoral immune response of newly received, lightweight beef heifers.
TL;DR: Neither supplemental Cu nor Zn source affected performance or morbidity of lightweight, newly received heifers; however, source of both Cu or Zn affected the humoral immune response to OVA, although source effects were not consistent for the two minerals.
