German Farmers' Awareness of Lameness in Their Dairy Herds

Abstract

Lameness is one of the most challenging problems in the dairy industry. Control is impeded because farmers often underestimate the number of lame cows. The objectives of this study were to assess German farmers' awareness of lameness in their herds and to determine the associations between farmers' awareness and their management practices, farm characteristics as well as with farmers' education, personality traits and attitudes. As a part of a large cross-sectional study, veterinarians visited farms in three structurally different regions of Germany: north (n = 253), east (n = 252), and south (n = 260). The cows (n = 84,998) were scored for locomotion and farmers were asked to estimate the number of cows that were lame or did not walk soundly. The ratio of farmers' estimated prevalence and the veterinarians' observed prevalence (Farmer's Detection Index; FDI) was calculated. The median lameness prevalence assessed by the veterinarians was 23.1, 39.1, and 23.2%, and the median prevalence of lame cows estimated by the farmers was 9.5, 9.5, and 7.1% in the north, east, and south, respectively. On average, farmers were conscious of only 45.3% (north), 24.0% (east), and 30.0% (south) of their lame cows. Farmers managing their herds according to organic principles had a higher FDI than farmers who managed their herds conventionally. Surprisingly, no significant associations between FDI and factors concerning claw health management could be detected. Therefore, increased awareness did not seem to be necessarily linked to improved management. Moreover, the FDI was not significantly associated with farmers' education or herd size. In the south, more extraverted farmers had a lower FDI. Those farmers who totally agreed with the statement, “I am satisfied with my herd's health,” had a lower FDI than farmers who disagreed or were undecided. Moreover, farmers who disagreed or were undecided with the statement, “It affects me to see a cow in pain” had a higher FDI than those farmers who agreed to the statement. The results indicate that poor awareness of lameness was linked to the farmers' attitude and personality. Therefore, new approaches concerning the consultation regarding lameness control, such as the use of Motivational Interviewing, might be useful in the future.

How might the public contribute to the discussion on cattle welfare? Perspectives of veterinarians and animal scientists

“…For instance, in some of our previous focus group work (Ventura et al 2014 ) veterinarians, farmers and other dairy professionals identified lameness as a key welfare concern facing the dairy industry. However, the dairy sector continues to be challenged by the identification and treatment of lame cows in need of care (Jensen et al 2022 ), despite increasing attention to and awareness of lameness as a production and welfare challenge by dairy stakeholders (Wynands et al 2021 ).…”

Random forest classification as a tool in epidemiological modelling: Identification of farm-specific characteristics relevant for the occurrence of Fasciola hepatica on German dairy farms

“…Parity data were retrieved from DHI. A face-to-face, pen-and-pencil interview was conducted with the responsible farm manager as elaborated on by Jensen et al [ 40 ]. In brief, the attitude of the farmers towards their work on the farm was assessed and farmers rated their consent to each statement on a five-point Likert scale (“strongly disagree”, “disagree”, “neutral”, “agree”, “strongly agree”).…”

Leistungsdaten und Abgangsursachen von Hinterwälder-, Vorderwälder-, Fleckvieh- und Holstein-Kühen in den Jahren 1953 bis 2021

“…in Bayern (9,0–12,5%) 42 wegen dieser Ursache und den Lahmheitsprävalenzen von Kühen, die in Süddeutschland bei 23,2% lagen. In Ostdeutschland betrugen sie sogar 39,1% 43 . In einer anderen aktuellen Untersuchung lag die Lahmheitsprävalenz in ostdeutschen Großbetrieben, wenn ein – schon „veterinärmedizinisch behandlungswürdiger“ – Lahmheitsgrad von 3/5 zugrunde gelegt wurde, im Mittel bei 31,1% (21,8%–37,4%) 4 .…”
