| Abstract | ||||
| This study is a trial to focus light on the immunological status of the new born camel calves before and after ingestion of colostrum and during the first 8 months of life (weaning age). This was done through estimation of serum total protein levels and their fractions, mainly globulin fractions of 14 apparently healthy camel calves. Blood samples were collected just after birth before suckling and after suckling colostrum at different times till 8 months of age. Serum total protein was found low at; birth, then, it markedly increased postcolostral ingestion to reach its maximum level after 24 hours. This elevation might be due to concomitant rise in gamma globulins and albumin levels. Total protein level gradually decreased after 48 hours post-colostral Ingestion and reached its normal level after one week. Albumin level was significantly elevated postcolostral ingestion and reached its maximum level after 24 hours, then, it significantly decreased all age of 2 weeks. Alpha globulin showed higher levels et time of birth and 24 hours after ingestion of colostrum, then, it gradually decreased till the age of 3 weeks. Beta globulin level was found low at birth, and progressively increased postcolostral Ingestion for 2 days followed by gradual decrease till the age of one month. Camel calves are born with low levels of gamma globulins in their sera. but their levels markedly rise 24 hours post-colostral ingestion. This makes its importance for the new born calves to secure the colostrum from their dams as soon as possible as they represent the principal mechanism by which young calves ague° maternal immunity. From the first to 8th months of age (weaning age) no significant differences were detected between protein levels and their fractions. | ||||
