Abstract

Growing meat goats of 4 types (Boer (B) wethers and doelings, 25 ± 1.0 and 22 ± 0.7 kg; Spanish (S) wethers and doelings, 17 ± 0.3 and 16 ± 0.2 kg, respectively) were used to evaluate conditions for a method to test efficacy of electric fence strand addition to barb wire fence for cattle to contain goats. Animals were allocated to 8 sets of 20, consisting of 5 groups/set and 1 animal type/group. There were 5 2.4 × 3.7 m test pens consisting of 3 sides of metal panels and 1, adjacent to a pasture with abundant vegetation, of barb wire strands at 30, 56, 81, 107, and 132 cm from the ground. Fence treatments were electric strands at 15 and 43 (LH), 15 and 23 (LM), 15 (L), 23 (M), and 43 cm (H) at 6 kV. Adaptation procedures entailed 4 sequential weekly exposures to test pens: no electric strands, 1 strand at 0 kV, LH, and LH. Two preliminary treatments were imposed the week before the first observation period in wk 1: barb wire with no electric strands vs. LH. All sets were observed for 1 h in wk 1, and 4 sets were exposed to the same fence treatment in wk 6. During the 5 wk between observations, sets were exposed to 2 washout treatments while on pasture: without or with electric strands at ≥ 6 kV situated next to concentrate feeders. There were no effects of gender, preliminary, or washout treatments (P > 0.05). The % of animals exiting test pens differed (P
