Associations between Sow Body Lesions with Body Condition and Subsequent Reproductive Performance

The objective was to determine the association between foot, leg, vulva and shoulder lesions with body condition reproduction in group housed sows. Whiteline sows (n = 887) were measured before farrowing at weaning a commercial farm eastern North Carolina. Foot leg abnormalities included cracked hooves, toe length differences, overgrown hooves locomotion. Vulva scored no lesion or present. Shoulder lesion, abrasion open wound. Sow measures Knauer sow caliper (CS), weight (WT), visual score (BCS), backfat (BF) longissimus muscle area (LMA). production traits number born alive, litter birth weight, weaned, piglet survival (number weaned ÷ (total + net transfer)), wean-to-conception interval average daily lactation feed intake. Data analyzed SAS using PROC GLM for continuous GLIMMIX categorical traits. recorded on 17.6% of 0% weaning. No lesions, abrasions wounds 100%, 0%, respectively, 73%, 21% 6%, not associated reproduction. lower CS, WT, BCS BF farrowing, reduced (4.3%). Lower CS increased Backfat had curvilinear associations weaning, 39 mm 4.2 minimizing lesions. Results suggest thinner survival.
