      A study was conducted to test the restrictive efficiency of 5 antelope pass structures upon cattle and sheep. Cattle and sheep were placed under 3 stress situations, female water, female young, and male-female, to test fence restrictive ability of individual antelope pass structures. No single structure restricted all classes and types of livestock. Depending upon livestock class and type, proper selection and use of antelope pass structure will restrict livestock movement without severely restricting antelope movement. An 81.3-cm (32 in) net-wire fence most effectively restricted sheep, but cattle were most effectively restricted by a 2.4-m × 1.5-m (8 ft × 5 ft) horizontal grill. It appears that a horizontal grill within a fence line with certain modifications and placement constraints will effectively restrict sheep and cattle but permit antelope passage.
