Electronic Tags

Cattle producers and other industry leaders learned about a new National Animal Identification System (NAIS) during the annual LSU AgCenter’s Rosepine Research Station Field Day May 6. The system would enable farmers and government officials to quickly track and contain animal disease outbreaks by using precise identification of each animal.

Weather Stations Provide Wealth of Information
Data Logger
The LSU AgCenter operates 25 weather stations at research stations and other cooperating locations throughout Louisiana. The Louisiana Agriclimatic Information System privides temperature and humidity data that researchers can correlate to livestock and crop production. Each station provides minute-by-minute measurements of air temperature, rainfall, wind speed, wind direction, relative humidity, solar radiation and soil temperature.
Ration Strategies for Hot Weather
One of the most difficult feeding challenges faced by dairy farmers is the dropoff in feed intake and milk production during the summer. To minimize these losses, rations must be specially formulated for hot weather.
Diseases of Louisiana Cattle
Cattle in all beef herds are subjected to some of the common diseases. Vaccines are available that can induce some degree of protection against several of the major diseases of cattle.
