Some authors recommend sand bedding, while many farmers still use sawdustor straw. Bedding choices may affect not only cow comfort but also udder health . Cow preferred to liedown in the stalls bedded with mattresses and sawdust and were least likely to use the concrete stalls withpaper. Cows were more likely to lie down in stalls when these had more bedding , regardless of whetherthe stall base was concrete, mat or carpet. Lameness is probably the most important animal welfare issuetoday in dairy herds and a good partion of the lameness observed in dairy cows may be attributed tolaminitis secondary to high grain feeding. Ruminal acidosis can be direct human health concern as well.Low ruminal and intestinal pH due to high grain feeding increases the risk shedding enterohemoragic E.coli. Compromises in dairy cow health due to subacute ruminal acidosis (SARA) are a concern not onlyfor economic reasons but also for animal welfare reasons. Rumenitis is the fundamental lesion of SARAand it leads to delayed , chronic health problems. Once the ruminal epithelium is inflamed bacteria maycolonize the papillae and leak into portal circulation . These bacteria may cause liver abscesses, whichsometimes cause peritonitis around site of the abscess. If the ruminal bacteria clear the liver, they maycolonize the lungs, heart valves, kidneys or joints. SARA may also be associated with laminitis andsubsequent hoof overgrowth, sole abscesses and sole ulcers .These foot problems generally do not appearuntil weeks or months after the bout of ruminal acidosis that caused them.
