Loading and Unloading Weaned Pigs: Effects of Bedding Types, Ramp Angle, and Bedding Moisture.

Garcia A, McGlone JJ - Animals (Basel) (2014)

Bottom Line: Providing bedding reduced (P < 0.05) scores regardless of whether the bedding was dry or wet.Scores increased as the slope increased (P < 0.01).Provision of bedding, other than feed, at slopes greater than zero, decreased slips, falls and vocalizations.

ABSTRACT
The use of non-slip surfaces during loading and unloading of weaned pigs plays an important role in animal welfare and economics of the pork industry. Currently, the guidelines available only suggest the use of ramps below 20° to load and unload pigs. Three ramp angles (0°, 10° or 20°), five bedding materials (nothing, sand, feed, wood shavings or wheat straw hay), two moistures (dry or wet bedding; >50% moisture) over two seasons (>23.9 °C summer, <23.9 °C winter) were assessed for slips/falls/vocalizations (n = 6,000 pig observations). "Score" was calculated by the sum of slips, falls, and vocalizations. With the exception of using feed as a bedding, all beddings provided some protection against elevated slips, falls, and vocalizations (P < 0.01). Providing bedding reduced (P < 0.05) scores regardless of whether the bedding was dry or wet. Scores increased as the slope increased (P < 0.01). Provision of bedding, other than feed, at slopes greater than zero, decreased slips, falls and vocalizations. The total time it took to load and unload pigs was affected by bedding type, ramp angle, and season (P < 0.05). Minimizing slips, falls, and vocalizations when loading and unloading pigs improved animal welfare.

Least Square means ± 0.33 for weaned pig scores with the use of wet or dry bedding materials (P < 0.05). Beddings abbreviated by N = nothing, F = feed, S = sand, WS = wood shavings, H = hay. Bedding was rated based on a score system which was calculated by the sum of slips, falls, and vocalizations. n = 30 observations/bedding moisture.

Bedding was rated based on a score system which was calculated by the sum of slips, falls, and vocalizations. n = 30 observations/bedding moisture.

Mentions: The interaction between moisture and bedding type was significant at (P < 0.05). The scores for dry ramp within bedding were similar, with the exception of feed (Figure 2). Scores for nothing were not different than the other beddings, including feed (P > 0.05), but dry feed scores differed from other beddings (P < 0.05). The most evident protection on a dry surface was provided respectively by sand, hay, and wood shavings. The lowest score on a dry surface was with sand (0.6 ± 0.75; P > 0.05). On a wet surface the use of hay, wood shavings, sand, and feed reduced scores significantly compared to nothing. The lowest score with a wet surface was with hay (0.8 ± 0.75; P > 0.05). In the current study, using feed as a bedding was not beneficial in reducing slips, falls, and vocalizations when the ramp was dry. However, if the ramp surface was wet, using feed, or any other bedding was better than not using anything at all.
