Nails and metal in your Livestock? Here is how to prevent - Hardware disease

Dear Daktari

Thanks for your weekly very educative articles on livestock health. I am a dairy farmer here in Kabarnet, Baringo County. I lost a very good Friesian cross to hardware disease as diagnosed by my veterinary doctor. I later realised the free ranging I practice and some construction work that was ongoing on my farm might have been the cause for this disease. Why is this disease common and how can it be prevented?
