IMPROVEMENT IN MILK-PRODUCTION AND UDDER HEALTH FOLLOWING CORRECTION OF STRAY VOLTAGE ON COMPUTER FEEDERS

Diagnosis and correction of stray voltage on farms is important, as wa s shown here on a 130-cow Holstein dairy farm which had installed comp uterized grain feeders in 1986. This may be especially true when cows can choose to avoid the source of shocks, and this choice affects prod uction. Major production and disease losses in dairy cattle were stron gly associated with stray voltage, and improvement followed its elimin ation on the farm in this study.
