Whilst livestock management technologies may help to improve productivity, economic performance, and animal welfare on farms, there has been low uptake of technologies across farming systems and countries. This study aimed to understand dairy farmers' intention to use calf management technologies by combining partial least squares structural equation modelling (PLS-SEM) with qualitative comparative analysis (QCA). We evaluated the hypotheses that dairy farmers will intend to use calf technologies if they have sufficient competencies, sufficient materials, and positive meanings (e.

The housed environment for dairy cattle is of critical importance to their health, wellbeing, and productivity. Lack of space is an important factor for housing quality assessment due to links with increased likelihood of disease. A recently published randomized controlled trial identified that greater living space provision increased lying time, milk volume production, and also increased time to conception.

Article Synopsis
  • Precision livestock technologies can detect subtle behavioral changes in farm animals, which serve as early indicators of disease or stress.
  • Individual baseline behaviors vary significantly among animals, necessitating the measurement of both repeatability (consistent mean behaviors) and predictability (day-to-day variation) to identify abnormalities effectively.
  • This study quantified the repeatability and predictability of lying and feeding behaviors in dairy cows using sensor data, revealing significant individual differences, with repeatability values of 0.38 for feeding and 0.34 for lying, as well as predictability coefficients of 0.46 and 0.29, respectively.

There is currently societal interest and concern for dairy cow welfare. It has been suggested that boredom poses a welfare issue for dairy cows, particularly when presented with extended disposable time in housed environments that lack stimuli. Farm animals experience a multitude of affective states, which has created a need for positive experiences to be included in welfare management.
