A calf had also died showing similar symptoms during the previous year. All calves showed identical symptoms. Initially, their liveliness diminished; subsequently, they drank less and showed signs of pica. They finally died after the disease had run its course for about six weeks. The last calf, born late in February 1962, was in poor health as early as May, improved slightly when it had been sent out to grass but died in September, having fallen ill again in August. Autopsy was performed on three calves; all three were affected with chronic interstitial nephritis and uraemic endocarditis of the left auricle was present as well. The results obtained on toxicological investigation were indicative of lead poisoning. The liver of the calf was found to contain two mg of lead per kg, the cortex of the kidney containing twenty-five mg of lead per kg. These figures did not provide direct evidence of lead poisoning, but in evaluating these figures the fact was taken into account that the calf had no longer been able to ingest any lead for several months. Meanwhile, it was found that the stock-owner had fitted an old painted door in the calf-shed, which door was constantly being licked by the calves. The paint contained 18.6% of lead. This finding was followed by examination of the liver of a calf that had died previously. It was found to contain 49.7 mg of lead per kg. Accordingly, the calves had been affected with a form of lead poisoning running a relatively slow course, as a result of which the animals had developed chronic interstitial nephritis. The calves eventually died from uraemia. 4 references. %0Journal Article %N;Journal ID: CODEN: TIDIA %1 %CNetherlands %Rhttps://doi.org/ Journal ID: CODEN: TIDIA HEDB %GDutch
