Purebred Holstein-Friesian from the Netherlands were observed at Chiangmai Livestock Breeding Center. The blood parasites, Theileria and Babesia were the most serious and chronic problems. These parasites caused anemia, increased body temperature and rapid and shallow respiration. These symptoms disappeared after receiving 500 mg chlortetracycline by mixing in the concentrate. The animals did not show any digestive disorders. The cows were very sensitive to insects and ticks which are the main blood parasite vactors. Electric fan was needed to expel files and heat. Hoof defects and arthritis were also observed. It was concluded that regular hoof care (hoof trimming, foot bath) was necessary to maintain good health of the cows. Good management and feeding were essential for obtaining the optimum production from the observed cows.
