Joint HVDC Agricultural Study : Final Project Report.
A 3-year long study was conducted in central Oregon to determine the possible effects of a +-500-kV d-c transmission line on cattle and crops. Two herds totaling 100 beef cows and 6 bulls were confined in pens beneath the d-c line. The cows were paired and the other members of the pairs were maintained in two herds in control pens 2000 ft west of the line. The management facilities under the power line were duplicated in the control area. There were no significant differences in consumption of feed, minerals or water between the line and control herds. Also, no effects were found on breeding, conception, calving, calf birth date, calving interval, average daily gain, adjusted weaning weight, cow weight, condition, carcass weight, and mortality. Differences were found between years for calf birth date, average daily gain, adjusted weaning weight, and cow weight. These differences were attributed to condition and age of the cows entering the study and their adjustment to pen confinement. 67 refs., 50 figs., 106 tabs.
