An on-farm study comparing farm management practices and animal health was carried out. The study also focussed on a slaughterhouse analysis by comparing impacts on the safety and quality of the cattle products. Twenty-four organic and 26 conventional farms were inspected, and farmers responded to a questionnaire that covered all basic data on their husbandry practices, farm management, veterinary treatments and reproductive performance during 2007. Furthermore, data on the hygiene and quality of 244, 2596 and 3021 carcasses of calves from organic, intensive and conventional farms, respectively, were retrieved from the official yearbook (2007) of a slaughterhouse. Differences found between organic and conventional farms across the farm analysis did not substantially reflect differences between both farm types in the predominant diseases that usually occur on beef cattle farms. However, calves reared organically presented fewer condemnations at slaughter compared with intensive and to a lesser extent with conventionally reared calves. Carcass performance also reflected differences between farm type and breed and was not necessarily better in organic farms PB Elsevier SN 1751-7311 YR 2012 FD 2012 LK http://hdl.handle.net/10347/24270 UL http://hdl.handle.net/10347/24270 LA eng NO Animal, Volume 6, Issue 9, 2012, Pages 1503-1511 NO This study was supported by the Xunta de Galicia (Spain;PGIDT02RA6261001PR) and I.B.P. received a research fellow-ship (AP2003-3835) from the Ministry of Science of Spain DS Minerva RD 24 abr 2026
