Blackleg is a highly fatal disease of young cattle caused by the spore forming, rod shaped, gas producing bacteria Clostridium chauvoei. The spores of the organism can live in the soil for many years. The bacteria enters the calf by ingestion and then gains entrance to the body through small punctures in the mucous membrane of the digestive tract.

Having a ladybug land on you can be a magical moment. While other insects may pose a threat to humans, animals and crops alike, ladybugs are harmless -- and even better, they're beneficial!

A single ladybug can eat as many as 5,000 aphids in its lifetime, according to the University of Kentucky Department of Entomology.
