Today we will be exploring some interesting studies relating to the welfare of farmed animals.  As we have discussed before, billions of farmed animals around the world endure significant suffering and inhumane treatment to feed humans, largely in industrial farming. And yet, like other animals, cows, pigs and chickens, are sentient with clearly documented evidence of emotions, personality differences, kinship with others, etc.  For those of us who consume animal products, we can make a real difference in the lives of animals by insisting upon better animal welfare in the human food system.  There are many factors that need to be addressed (nutrition, health, environment, behaviour, and mental state) and much work needs to be done.  And our guest today is one of the people involved.

 Dr. Maria Camila Ceballos Bettancourt, is an assistant professor in the School of Veterinary Medicine at the University of Calgary in Alberta Canada.  She has a specialization in beef cattle welfare but, as you will hear, she has been involved in a number of really interesting studies involving pigs and chickens also.  She will talk about music and its impact on pigs, the positive benefits of silvopasturing on cattle and how different practices of handling chickens can have a big impact on their welfare.
