BY LJ. HUTCHINSON Penn State University UNIVERSITY PARK (Centre) There are normally five differ ent species of lice that can attack cattle in North America. The four blood-sucking lice are the little blue louse, the longnosed louse, the shortnosed louse, and the cattle tailed louse. These lice are considered to be the most eco nomically damaging to cattle because of the health problems they can cause. The cattle biting louse is a chewing or biting louse and is not considered to be as a great a problem because it does not suck blood. Lice are host specific, spending their entire life on their specific specie of animal. Lice are general ly spread from animal to animal by direct contact, the most com mon means of transmission being from cow to calf. Fall or early spring calves are unthrify cattle usually having the heaviest lice infestations. These cattle are usu ally in poor condition with rough, patchy haircoats that have a dirty appearance. Heavy lice infestation can cause severe blood loss of the host animals which can cause reduced weight gains, lowered vit ality, disease resistance and milk production. Cows may abort due to louse-induced anemia. Cattle are most susceptible to lice during the winter months. During the cold weather, the time it takes for the eggs to hatch and grow into adults is three to four weeks. This cycle is slowed down with warmer temperatures. The maximum life for lice is approxi mately 45 days. KING CONSTRUCTION CO.
