Training cattle to avoid electric fences before turnout to grazing reduces the risk of the animals breaking out from their paddock. We investigated the time needed for dairy bull calves to learn to avoid a light-built electric fence. Nineteen dairy bull calves were trained to an electric fence in a training yard during seven days. The number of electric shocks the animals received from the training fence was recorded continuously. After the training period, the calves were turned to pasture. Nine of the animals were also grazed the following summer as yearlings, and observed before turnout in a smaller enclosure. The calves got more shocks from the fence during training hour 1 than during any of the following seven hours. The number of shocks the calves received from the fence also declined from training day 1 to 2 and from training day 3 to 4. The results indicate that the dairy bull calves learned to avoid an electric fence quickly, even within an hour from release into the training yard. A simple training procedure was sufficient to ensure that the animals could be grazed in and would avoid a light-built electric fencing system as calves and, even after a winter-housing period, as bulls.;

Abstract Impact of grazing method on ewe performance, parasite infestation, and soil was examined using mature, non-lactating ewes divided into slow rotation (SR; n = 20) or daily rotation (DR; n = 20) groups. Pastures previously grazed by sheep were divided and soil sampled. Temporary electric fence provided daily pasture allocation for DR. Ewes had been adapted to temporary electric fence for two weeks. Both DR and SR were moved to new pasture at the same time. Ewes were weighed and fecal egg counts were conducted biweekly. On alternate weeks, ewes were body condition scored (BCS), FAMACHA scored, and dewormed if FAMACHA score was 4 or greater. After 10 weeks of grazing (June 1-August 10, 2018), final ewe weights and soil samples were collected. Body condition score, FAMACHA, fecal egg count, body weight, and soil test results were tested for effect of grazing group, date, and group by date interaction using procedures for repeated measures with JMP software (version 10, SAS Inst. Inc., Cary, NC). The FAMACHA scores were greatest on July 6 (P < 0.0001). BCS were greater on June 8 and 22 than July 6 and August 3 (P < 0.0001). Ewes were heaviest on June 1 and 15, lightest on July 27 and August 10 (P < 0.0001), and DR ewes were lighter than SR ewes on July 27 and August 10 (P < 0.0001). No effect of treatment, date, or treatment by date interaction on fecal egg count (P > 0.23) was detected. Soil organic matter decreased over the study (P = 0.0024), but organic matter change was less in DR than SR (P = 0.0092). DR did not influence parasitism, but may enhance soil organic matter.
