A protocol was developed by consultation with experts on the welfare of cattle to use direct observations of cattle and an examination of farm records to assess welfare. Fifty-three dairy farms in England were visited and assessed during the winter of 2000/01. The findings were compiled and the results of the welfare measurements were examined by 50 experts who indicated at what level they considered that improvement was required. More than 75 per cent of them considered that 32 of the 53 farms needed to take action to reduce the incidence of mastitis, and that at least 42 of the farms needed to take action to reduce the prevalence of lameness, overgrown claws, swollen and ulcerated hocks, and injuries from the environment.
A questionnaire to examine the attitudes and perceptions of cattle practitioners to pain in cattle was sent to 2398 practitioners working in the UK, and 641 responses were received. From the range of procedures and conditions outlined in the questionnaire, claw amputation was scored as the most painful procedure undergone by adult cattle (assuming no analgesic drugs were administered), and neck calluses were scored as the least painful condition experienced by adult cattle. The pain associated with dystocia was considered the least painful experience for calves, and fracture of a distal limb and surgery for an umbilical hernia equally the most painful. There were significant differences between the pain scores assigned by men and women and by respondents who had graduated in different decades; female respondents and more recent graduates tended to give a higher pain score for most conditions. There were also significant differences between the pain scores assigned by respondents who routinely used analgesics and those who did not, the latter being more likely to assign significantly lower pain scores.
Visits were made to 205 dairy farms in England and Wales between October 2006 and May 2007 by 1 or more of 4 researchers. At each visit, all milking cows were locomotion scored (lameness scored) using a 4-point scale (0=sound locomotion, 1=imperfect locomotion, 2=lame, 3=severely lame). The mean prevalence of lameness (scores 2 and 3) across the study farms was 36.8% (range=0-79.2%). On each farm, the presence within the housing and grazing environments of commonly reported risks for increased lameness was recorded. Each farmer was interviewed to gauge the ability of the farm staff to detect and treat lameness. A multivariable linear regression model was fitted. Risk factors for increased lameness were the presence of damaged concrete in yards, cows pushing each other or turning sharply near the parlor entrance or exit, cattle grazing pasture also grazed by sheep, the use of automatic scrapers, not treating lame cows within 48h of detection, and cows being housed for 61 d or longer at the time they were locomotion scored by the visiting researcher. Having a herd consisting entirely of a breed or breeds other than Holstein-Friesian was associated with a reduction in lameness prevalence compared with having a herd consisting entirely of Holstein-Friesians.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
