Description
For the effects of voltages on health and reproduction, 40 cows in 2nd-5th lactation were divided into 4 groups of 10. These included a control group that was not subjected to voltages and 3 treatment groups that were given either 1, 2 or 4 V at the water bowl. Cows in the treatment groups were exposed during the entire lactation to voltage whenever they drank. Voltages did not sufficiently affect milk yield. General health parameters studied were mastitis, hoof problems and changes in body wt. Reproductive and calving parameters examined were days to 1st breeding, days open, services per conception, response to PGF2alpha, calving intervals, visible abortion and calves born dead. Voltages did not significantly influence cow health or reproductive performance
