The Effects of Using a Ramp and Elevator to Load and Unload Trailers on the Behavior and Physiology of Piglets.

McGlone J, Sapkota A - Animals (Basel) (2014)

Bottom Line: Sitting, feeding and blood parameters did not show a significant treatment by time effect (p > 0.05).Standing behavior did not differ between CON and HAN piglets nor between RAM and ELE piglets (p > 0.05); however, CON and HAN piglets stood more than RAM and ELE piglets during treatment (p < 0.05).The heart rate of ELE piglets decreased 6.3% after treatment; whereas the heart rate of RAM piglets remained elevated 2.4% (p < 0.05).

ABSTRACT
Transport is an inevitable process in the modern U.S. swine industry. The loading process is a novel and potentially stressful experience. This study uses behavior, heart rate and leukocyte counts to compare stress one hour before, during and after loading via ramp or elevator. Piglets were held in a home pen (control (CON)), walked up and down an aisle (handled (HAN)), or walked to a truck and loaded via elevator (ELE) or ramp (RAM). Sitting, feeding and blood parameters did not show a significant treatment by time effect (p > 0.05). Standing behavior did not differ between CON and HAN piglets nor between RAM and ELE piglets (p > 0.05); however, CON and HAN piglets stood more than RAM and ELE piglets during treatment (p < 0.05). After treatment, drinking behavior was increased in RAM piglets (p < 0.05). The heart rate of ELE piglets decreased 6.3% after treatment; whereas the heart rate of RAM piglets remained elevated 2.4% (p < 0.05). In terms of heart rate, loading by elevator appears to be less stressful than loading by ramp.

animals-04-00535-f002: Percentage of pigs showing standing behavior an hour before (A), during (B) and after (C) each treatment (control, handling, ramp and elevator).

Mentions: A significant treatment × time interaction was observed for standing behavior during treatment (37.20 ± 6.94%, 24.70 ± 6.94%, 75.80 ± 6.94% and 93.90 ± 6.94% for CON, HAN, ELE and RAM, respectively; p < 0.01). Standing behavior did not differ among CON and HAN pigs (p > 0.05). ELE and RAM piglets showed greater frequency of standing behavior than did CON and HAN (p < 0.05); however, standing behavior among ELE and RAM piglets did not differ from each other during treatment. Figure 2 shows the percentage of piglets standing at each time point.
