Animal husbandry has evolved since the dawn of human civilization. Rising demand for products and byproducts from animal husbandry is owed to the exponential increase in the global population. In order to meet these demands, animal husbandry professional have resorted to various practices to increase the yield. Just like us, animal health is governed not only by the feed that is provided to them, but also internally, by the millions of tiny microscopic beings residing within their gut.
Gut microbes are present in the intestinal tract of all animals however they are extremely crucial for ruminants like cattle. These ruminants are able to digest and utilize cellulose in their diet only because of the specific enzymes produced by these gut microbes.
Rats can act as vectors of diseases due to their ability to absorb disease agents from their environment and spread these pathogens, endangering the health of poultry and even humans. A study on the feces of rats caught in a poultry farm in British Columbia, found that rats carried potentially harmful multidrug resistant strains of avian Escherichia coli. These bacteria have the ability to cause gastrointestinal disease in poultry. The same strain of the bacterium has also been associated with human infections as well. The pathogenic bacteria was also isolated from the fur and appendages of one quarter of the trapped rodents.
