RESUMO
The present study aims to evaluate the amount of immunoglobulins A, G, and M in she-camel blood serum in relation with the presence of pathogens in the udder, and to compare the antioxidative capacity and the concentration of zinc, iron, total proteins, and calcium. Milk and blood samples from she-camels from south Jordan were taken; according to milk bacteriological examination, the animals were divided into two groups: (Gm) which contained samples of milk contaminated with bacteria and (Gh) which contained uncontaminated milk samples. Milk and blood were sampled from 30 females and examined for the concentration of immunoglobulins A, G, and M and for the presence of pathogens in milk. Total antioxidant capacity, zinc, iron, total proteins, and calcium concentrations in blood were determined. Milk samples were checked for the presence of pathogens. She-camels for the study were of similar age and productivity in the middle stage of lactation. It was determined that the presence of pathogenic bacteria infecting the udder quarters had considerably influenced the values of immunoglobulins G, A, and M, total antioxidant capacity, and zinc and total protein concentration (p < 0.05) in blood serum; no significant difference in iron and calcium concentration was determined. Subclinical mastitis has a crucial role in increasing the concentration of immunoglobulins in serum; some parameters measured in blood (zinc, total antioxidant capacity, total proteins) could be indicative for the presence of inflammation in she-camels.
