Dirt Score in Large White Yorkshire Piglets during Preweaning Period Reared on Cement Concrete Floor

An experiment was carried out on 24 Large White Yorkshire piglets of either sex at the pig unit of LFC of C.V.Sc., Rajendranagar, Hyderabad from birth to weaning. All experimental piglets were reared on normal conventional concrete flooring along with their mother till weaning (56 days). An evaluation of cleanliness (dirt scoring) was performed fortnightly during the experimental period. Pig cleanliness was assessed using a fivepoint scale on 4 anatomical areas: rear, back, and both flanks, and each area was given a score from 0 to 4. The observed fortnightly dirt score was 0.56 ± 0.03, 0.60 ± 0.02, 0.70 ± 0.02, and 0.97 ± 0.11 at first, second, third, and fourth fortnight respectively. There was a continuous increase in dirt score as the age advances. Statistical analysis revealed the mean dirt score at the fourth fortnight was significantly (P<0.01) different from the first, second, third, and overall mean dirt score.
