The development and use of facial grimace scales for pain measurement in animals

The measurement of pain in animals is surprisingly complex, and remains a critical issue in veterinary care and biomedical research. Based on the known utility of pain measurement via facial expression in verbal and especially non-verbal human populations, “grimace scales”...

Rams recognize and prefer the human who regularly brushed them

Brushing produces a relaxing effect and improves the welfare of ewes and lambs and the human-animal relationship. Lambs gently handled during rearing are less fearful to humans in their adulthood, but there are few studies on the development of a...

Applications of behavioral training to laboratory animals

How many of us have had this experience? We go to a conference, we read an article, we watch a video. We understand operant conditioning. We grasp the concepts behind clicker training, target training, and how we are supposed to...

MicroRNAs as biomarkers for animal health and welfare in livestock

MicroRNAs (miRNAs) are small and highly conserved non-coding RNA molecules that orchestrate a wide range of biological processes through the post-transcriptional regulation of gene expression. An intriguing aspect in identifying these molecules as biomarkers is derived from their role in...

Effect of three opioid-based analgesic protocols on the perioperative autonomic-mediated cardiovascular response in sheep

Few reports evaluate the clinical effects of opioids in sheep during experimental surgical procedures. Catecholamine-mediated haemodynamic changes resulting from surgical noxious stimulation are blunted by opioids. The aim of this study was to evaluate the efficacy of three opioid-based analgesic...

Effect of short-term seclusion of sheep on their welfare indicators

Separation from the group is a potent stressor for sheep and may have an adverse effect on animal welfare. Therefore, the present study was initiated to determine the effect of short-term seclusion of sheep on their welfare indicators in terms...

Effect of bedding for reducing the postshearing stress in sheep

Shearing of sheep is routine management. However, the shearing induces stress in the animal. To reduce the postshearing stress, providing bedding may be an effective method. Therefore, the present study was initiated to assess the effect of bedding for reducing...

Preliminary evaluation of sustained-release compared with conventional formulations of meloxicam in sheep (Ovis aries)

Sustained-release (SR) drugs refine current analgesic regimens by alleviating the need for multiple sessions of handling and restraint and by reducing the local tissue irritation that can occur due to repeated injections. Although a variety of SR drugs are already...

A protocol of human animal interaction to habituate young sheep and goats for behavioural studies

Animal habituation is key to obtain reliable data on behavioural studies but detailed procedures to achieve it are scarce. This study designed a set of actions to habituate sheep and goats to human observers. Pelibuey sheep (n = 15) and Criollo goats...
