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...

Agricultural animals as biomedical models: Occupational health and safety considerations

The use of agricultural animals in biomedical research is increasing. Their overall size and metabolic rate, organ size, longer gestation period, and other physiological similarities make them good candidates for animal models of human disease. There are a number of...

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...

How can we assess positive welfare in ruminants?

Until now, most research has focused on the development of indicators of negative welfare, and relatively few studies provide information on valid, reliable, and feasible indicators addressing positive aspects of animal welfare. However, a lack of suffering does not guarantee...

Evaluation of euthanasia of sheep with intravenous saturated salt solutions to enable the collection of whole, intact brains

Captive bolts or firearms are unsuitable for euthanasia of livestock when an intact brain is required for diagnostics. Injectable barbiturates can be used, but this method carries risk of poisoning animals eating the carcase. Intravenous saturated salt solutions have been...
