Abstract

Floor quality may affect the incidence of hoof diseases. If the manure scraping frequency is insufficient, the higher infection pressure occur (e.g. dermatitis), because the maceration of hooves become more intensive. Also the cow body cleanness is worse under these conditions. The effectivity of slurry scraping by mobile (robotic) scraping equipment was monitored in the stalls with slatted floors. The highest effectiveness was achieved after one-shot scraping and two consecutive scrapings, one follows the other in 4 hours (73.4% resp. 85.6%). Slightly lower efficiency of manure scraping was achieved using 3 hours interval after previous scraping, namely 68.9% in the case of one-shot scraping and 76.4% in the case of two consecutive scrapings. The high efficiency of scrapping was caused by better passage of large volumes of excrements through inter-slat gaps (the effect of compressive forces, so. “pulping”).
