Abstract: Failure of passive transfer of colostral IgG and efficacy of administered bovine and caprine colostrum as a source of lgG to camel neonates have been investigated. Neonates (N = 32) were randomly assigned to 1 of 3 treatments. Group 1 (N = 16) were left to suckle their dams. Group 2 neonates (N = 8) were colostrum deprived but supplemented with 500ml of pooled bovine colostrum given orally at 2 hour intervals from 2 to 20 hours after parturition. Group 3 neonates (N = 8) were treated similar to group 2 but with caprine colostrum. Suckling produced a peak concentration of 2700�270 mg dL^-1 of IgG in 75% of neonates. Twenty five percent of neonates had a maximum concentration of less than 800 mg dL^-1 and considered to be failure of passive transfer of lgG. Comparable neonatal serum IgG peak levels, apparent efficiency of absorption and t 1/2 was demonstrated between natural suckling (Group1) and bovine (group 2) and caprine (group 3) colostrums. It is suggested that administration of bovine and caprine colostrums could be considered in camel neonates when no cameline colostrum is available.
