Document Summary

Reduced production and product quality consumer. Minimal cost, high quality, products are raised ethically (taking animal welfare into consideration = minimal stress) Selection pressure on these organisms to mutate. Genetic selection for production traits is inversely correlated with health and fertility. Cv (increase hr), metabolic (no digestion), musculoskeletal, neuroendocrine, immune (fight response for microbial pathogens) Touch, taste, smell, hearing, sight, immune system recognition (immune cells are aware of the stressor in the body), microbiome (gut-brain axis, currently think that it can triggers the brain to signal there is danger) Neural (neuropeptides), endocrine (acth, cortisol etc), immune (release signals to the brain) feed into the brain. Activate neural receptors, get to the blood to activate brain directly. The cost is reduced health and fertility. Climate change likely to affect animal health. Management practices including biosecurity, genetic selection, what can we do to contribute to animal health. Stereotypic behaviour may be a coping behaviour for stress.
