Large livestock farms (which includes very large livestock farms) have been expanding in the last few years. This reflects the trend throughout Canadian agriculture towards fewer, larger farms producing more food, either for Canadian tables or for export. Large livestock farms are found in most agricultural areas of Canada. Notably, they’ve expanded in some of the country’s more intensely settled rural areas – those within commuting distance of metropolitan centres – where the human population has also been rising. An animal unit is the means of equally measure farm animals of different sizes based on feed input and manure output.
