The disease is a parasitic disease caused by several tapeworms parasitic in the small intestine of cattle. There are mainly Taenia saginata Monitz, Taenia Monitz, Taenia saginata and so on. These tapeworms are similar in morphology and development process. For example, Monitz tapeworm is long, baggy, segmented, milky white in color and up to 1 meters long. After the pregnant egg segments fall off, they are excreted with the feces of cattle. This segment was swallowed by an insect called soil mite, and the eggs developed into infectious larvae. In the pasture, there are many such soil mites. They like to climb on grass leaves in the morning and evening when there is dew and cloudy days, and cows are infected by eggs when they eat grass. Infectious eggs in the small intestine of cattle develop into adults in about 4 days. Calves are highly susceptible and seriously ill. When a large number of tapeworms are parasitic, it can cause stenosis, obstruction or rupture of the small intestine. Tapeworm can be 8 cm long in a day and night, and it needs to seize a lot of nutrients. In addition, the secretion of toxins can affect the digestion and metabolism of cattle and hinder the growth of calves.
