A scientific conception of animal welfare that reflects ethical concerns.
Scientific research on 'animal welfare' began because of ethical concerns over the quality of life of animals, and the public looks to animal welfare research for guidance regarding these concerns.
Effects of ad libitum milk intake on dairy calves.
It is concluded that ad libitum nipple feeding of milk to dairy calves can allow for increased milk intake and weight gain with no detrimental effects on intake of solid food after weaning.
Prepartum behavior and dry matter intake identify dairy cows at risk for metritis.
This research is the first to show that social behavior may play an important role in transition cow health and research is now required to determine how management should be changed to reduce or prevent illness in transition dairy cows.
Overstocking reduces lying time in dairy cows.
When cows had access to fewer freestalls, there was increased competition for stalls, increased time standing outside the stalls, and reduced lying time.
Invited review: effects of milk ration on solid feed intake, weaning, and performance in dairy heifers.
It is concluded that milk-fed dairy calves can safely ingest milk at approximately 20% of body weight (BW/d), and greater milk consumption supports greater BW gain, improved feed efficiency, reduced incidence of disease, and greater opportunity to express natural behaviors, which in combination suggest improved welfare.
Lying behavior as an indicator of lameness in dairy cows.
It is shown that high lying times, long lying bouts, and variability in the duration of lying bouts were associated with lameness, and that stall surface influenced the behavioral responses of lame cows.
Technical note: Validation of a system for monitoring rumination in dairy cows.
The objective was to validate the data generated by this electronic rumination monitoring system, which indicated that the electronic system was an accurate tool for monitoring this behavior in dairy cows.
Effect of hoof pathologies on subjective assessments of dairy cow gait.
To explore how hoof pathologies affect dairy cattle gait, we studied cows with sole hemorrhages (n = 14), sole ulcers (n = 7), and those with no visible injuries (n = 17). Overall gait assessments,
Reducing pain after dehorning in dairy calves.
The results indicate that ketoprofen mitigates pain after hot-iron dehorning in young dairy calves and that control animals demonstrated higher frequencies of these behaviors.
