Kala-Azar Dumdum Fever A human disease caused by LEISHMANIA. Kale Kale contains a factor which gives rise to goitre if fed in large amounts without other foods over a long period. Haemoglobinuria sometimes follows the grazing of frosted kale by cattle which may suffer anaemia without showing this symptom. The illness can be serious resembling POST-PARTURIENT HAEMOGLOBINURIA and may result in sudden death. The frothy type of bloat may also occur in cattle eating excessive quantities of kale - especially it seems during wet weather and when no hay is fed. There is some evidence to suggest that the feeding of large quantities of kale may lead to low conception rates and to mastitis. See also BLOAT. It should be added that kale anaemia and haemoglobinuria are by no means always associated with frosted kale but merely with an excessive probably over 18 kg 40 lb per cow per day intake of kale. The symptoms of kale anaemia include lassitude and rapid breathing and pulse-rate. Kangaroo Gait Kangaroo gait in ewes both in New Zealand and in the UK appears to be associated with disease of the radial nerves which causes difficulty in advancing the front feet.
