“…Hereditary diseases such as bovine chondrodysplastic dwarfism, Chediak‐Higashi syndrome and a deficiency of red cell band 3 have been reported in some populations of Japanese beef cattle (Moritomo and others 1992, Inaba and others 1996, Tu and others 1996a, b). Since the sire suspected of being the source of renal tubular dysplasia had excellent beef qualities, its pedigree cattle were used as sires or dams throughout Japan, and the disease might have been spread widely in Japanese Black cattle.…”

A new hereditary disease characterised by renal failure, poor growth and long hooves in Japanese Black cattle (wagyu) has been recognised in a region of central Japan since 1990. The number of calves affected has increased gradually, with the incidence reaching 17 of 485 (3.51 per cent) in 1995. Almost all the calves were slightly undersized at birth, and repeatedly had diarrhoea during the neonatal period. They began to show signs of growth retardation with proportional body and elongation of the hooves from about two to five months of age, but they had an almost normal or only slightly decreased appetite. The concentrations of urea nitrogen, creatinine and inorganic phosphorus in serum were high, and the affected calves excreted diluted urine frequently. Among 25 cases, the urine of 21 contained occult blood, 24 contained protein and two contained glucose. In 29 calves observed for 30 to 130 days, the course of the disease varied; in 21 of them it remained unchanged, six became gradually worse and two became severely debilitated and died. The disease was diagnosed as renal tubular dysplasia by histopathological examination.

“…Mating between the sire and its half‐sisters or daughters was commonly recommended. As a result, in some populations of Japanese beef cattle, hereditary diseases such as bovine chondrodysplastic dwarfism (Moritomo and others 1992), Chediak‐Higashi syndrome (Tu and others 1996a, b) and deficiency of red cell band 3 (Inaba and others 1996) have appeared, due to very strong selective pressures.…”
