The second experiment was conducted for a period of 8 weeks from August to
September, 2011. The cages were prepared as mentioned earlier. Two treatments were
carried out and one treatment consisted of a shelter and the other without shelter (control).
The experiment was conducted with 3 replicates per treatment. The shelter was made of
black plastic corrugated pipe for car which was cut in half (70 mm external diameter). The
tube had both internal and external grooves, creating a 33.0 cm length shelter with 12
grooves on both sides (Figure 1). The shelter had a screw at the start and the end of tube for
weighing.
