Abstract

Eighty Boer (B, 3.9 ± 0.17 yr and 56.3 ± 1.11 kg) and 80 Spanish (S) does (3.5 ± 0.18 yr and 37.6 ± 0.52 kg) were used to evaluate effects of method of grouping, single breed (SGL) and breeds combined (COM), on behavior (e.g., pen exit and shock) when exposed to barb wire fence with different electric strand additions. Five 2.4 × 3.7 m evaluation pens had 1 side of barb wire strands at 30, 56, 81, 107, and 132 cm from the ground. Fence treatments (FT) were electrified strands (6 kV) at 15 and 43 (LH), 15 and 23 (LM), 15 (L), 23 (M), and 43 cm (H). For adaptation, does were exposed in evaluation pens to no electric strands (NES), M at 0 kV, M at 0 kV, M at 4 kV, and NES in wk 1, 2, 3, 4, and 5, respectively. Then does were divided into 2 replication sets per grouping (2 B-SGL, 2 S-SGL, 2 B-COM, and 2 S-COM); each of the 5 pens held 4 does for 1-h exposure to FT while observing behavior visually and with video surveillance. Data were analyzed with the GLIMMIX procedure of SAS. There were significant main effects of grouping and FT and interactions (P
