Repetitive Cattle Deworming May Cause Drug Resistant Worms
From: CattleNetwork.com
April 21, 2010
Dewormers have provided effective parasite control, which has resulted in returns to farmers between $20 to $200/hd. The cost of these products is reasonable when compared to potential productions gains provided. Sheep and goat farmers have long battled with drug resistant worms, however until recently there has not been evidence of this is occurring in beef cattle. In fact, some of the first evidence of worm resistance in cattle was found in Wisconsin in 2002, when a backgrounder, who acquired calves from the Southeast, experience lower than expected weight gain during the fall.

Alfalfa Autotoxicity: Why you shouldn’t overseed alfalfa into an existing stand.
by Glenn E. Shewmaker
Extension Forage Specialist, University of Idaho
Alfalfa can be overseeded into a new seeding within about one year. After one year of a stand, overseeding is usually not successful. The factors that cause the overseeding failure are 1) competition for light, water, and nutrients; 2) autotoxicity; and 3) disease. New alfalfa seedlings are slow to establish and thus have difficulty competing with larger plants and weeds. Moreover, new alfalfa plants are stunted in growth. This is because alfalfa creates autotoxicity. Autotoxicity is a process in which established alfalfa plants produce chemicals that move into the soil and reduce establishment and growth of adjacent new alfalfa. A similar term, allelopathy, is the direct or indirect harmful effects of one plant on another through the production of chemical compounds that escape into the environment.
