[The supply of newborn camel foals (Camelus dromedarius) with immunoglobulin G].
A major problem in camel breeding in East Africa is the high mortality rate of young camel calves. The purpose of this research was to examine the quality of camel colostrum and extent of the calves passive immunization by maternal antibodies. In 31 camel birth on a ranch in Kenya, IgG concentrations in the colostrum and in the serum of the calf during the first three days of life were measured. IgG concentration in the serum of the calf reaches a maximum 24 hours after birth. In 39% of the examined calves, this maximum concentration was below 4 g/l. In 61% of the calves, an IgG concentration of more than 4 g/l was reached. No correlation was found between diseased animals and the IgG concentrations in the serum of the calves involved. A minor IgG concentration can be excluded as a reason for calves mortality. The high percentage of insufficient IgG concentration in the serum of the calves therefore must be caused by insufficient intake of colostrum. Future measures in order to decrease calves mortality must therefore try to improve the management of calves, especially the sufficient intake of colostrum.
