Cattle deaths

lyledunn
Some 10 prize bullocks died in quick succession whilst housed over winter in a cattle shed. The government vet was unable to reach a conclusion on cause but apparently does not discount electric shock as an indirect cause. 

The shed comprises steel columns and trusses with corrugated iron sheeting over. The floor comprises re-Inforced concrete slats over the slurry tank. The pens have steel barriers supported by steel posts all of which are heavily corroded but still making contact with other albeit fortuitously.

The earthing system is TT with the shed steelwork on its own providing a substantially low impedance of 5 ohms using a loop tester. A 100mA RCD protects the rather ropey lighting circuits.defccf32df3c757507a0db6ad0a35f87-huge-a5af3537-8eae-4a3c-9126-68fa60b61ac7.jpg

whilst the floor could be wet, I can’t conceive how a voltage difference could be established even if the steelwork was at 230v

    Before Mr Betteridge gets too excited, electrocution amongst cattle is rare especially those numbers, the most common cause of cattle deaths is one of the Clostridial diseases, most of them tend to be rapid and fatal, Clostridia is part of a family of anaerobic bacteria found in the soil and farm environments, grass, hay and water, it does take a while to spot as cultures have to be developed to identify the particular strain, just an observation.

    Presumably that would show up in the post mortem examination of the cattle and the death of ten bullocks would not remain unexplained for long. 


    However I only have a passing knowledge of cattle diseases from being an occasional driver of a knacker wagon back in the days when BSE first appeared in this country and from working around farms. So I'll leave the medical examinations to the vets and just check the electrical installation out as I have far more experience of locating vermin damage to electrical installations.
