Abstract
This study is a meta-analysis of the effects of the beta-agonists zilpaterol hydrochloride (ZH) and ractopamine hydrochloride (RAC) on feedlot performance, carcase characteristics of cattle and Warner Bratzler shear force (WBSF) of muscles. It was conducted to evaluate the effect of the use of these agents on beef production and meat quality and to provide data that would be useful in considerations on the effect of these agents on meat quality in Meat Standards Australia evaluations. We conducted a comprehensive literature search and study assessment using PubMed, Google Scholar, ScienceDirect, Scirus, and CAB and identification of other studies from reference lists in papers and searches. ..

Funding Acknowledgements
Funding for this study came from Meat and Livestock Australia that supported the investigation in order to improve understandings of the effects of these agents on meat quality. The funders did identify papers, but these were not different to those found on literature search. The funders had no other role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
