Depth video data-enabled predictions of longitudinal dairy cow body weight using thresholding and Mask R-CNN algorithms [PDF]
arXiv, 2023 Monitoring cow body weight is crucial to support farm management decisions due to its direct relationship with the growth, nutritional status, and health of dairy cows. Cow body weight is a repeated trait, however, the majority of previous body weight prediction research only used data collected at a single point in time.

US employment exposure to domestic and foreign tariff changes under NAFTA
Applied Economic Perspectives and Policy, EarlyView.Abstract Literature examining the effects of changes in trade agreements and import competition on US employment and wages has focused primarily on non‐agricultural industries and changes in US import tariffs. We propose a method for measuring worker exposure to changes in agricultural tariffs using a newly developed county‐level dataset of employment ...

Harnessing the genetics of the modern dairy cow to continue improvements in feed efficiency.
Journal of Dairy Science, 2016 Feed efficiency, as defined by the fraction of feed energy or dry matter captured in products, has more than doubled for the US dairy industry in the past 100 yr. This increased feed efficiency was the result of increased milk production per cow achieved

Applied Economic Perspectives and Policy, EarlyView.Abstract Animal welfare programs alone are insufficient to ensure better welfare for farm animals. Effective farm management, driven by dairy farmers' intrinsic motivation, plays a pivotal role. This study examines the factors influencing dairy farmers' intention to implement animal welfare practices and their commitment to continuously enhancing ...

PATHOGENESIS OF LAMINITIS IN DAIRY COWS
ВЕТЕРИНАРСКИ ЖУРНАЛ РЕПУБЛИКЕ СРПСКЕ, 2023 The lameness is the earliest but also the most important clinical symptom of the achropodium diseases in cattle. According to literary data, in 90% of cases, the cause of lameness is localized in the hooves, and in 10% of cases it is in other anatomical parts of the limb.
