Title: Influence of Management System, Parity Orders and Stage of Lactation on Camel Milk Composition
Author: Elhassan, Sara Mirghani Bashir Mohamed
Abstract: This study aimed to evaluate the effect of management system, parity order and stage of lactation on camel milk composition (fat, solids not fat, total solids, protein and lactose), density and some macro minerals (Ca, Na, K and P). Sixty nine samples of milk were collected from three camel rearing systems; namely, intensive, extensive (semi dessert habitat) and extensive (rich Savanah habitat) at Khartoum, Gezira and Sennar States, respectively. The results indicated that the management system exerted significant (P≤0.05) effects on fat, SNF, TS, protein, lactose and density. Milk samples from the rich Savanah habitat (extensive system) had the highest chemical components, while the samples from the semi desert habitat (extensive system) recorded the least components, with the intensive system being intermediate. The parity order, on the other hand, had significant (P≤0.05) effect on the SNF, protein and lactose content in the third parity with the highest level in the advanced parity samples. The stage of lactation also affected milk components significantly (P≤0.05) in favor of the early and medium compared to the late stage samples, which recorded the least components. The mineral content was significantly (P≤0.05) higher in the samples from intensive and extensive rich Savanah habitat in Ca and P, while Na and K were significantly higher in the samples from the extensive system in semi desert habitat. The parity order influence only the Na content, while the stage of lactation affected Ca, Na IX and K. The highest concentration of Na (202.1 mg/g) was recorded at the late stage of lactation, and Ca 147.3 mg/g and K 226.6 mg/g at the medium stage of lactation. In conclusion, management systems are the main factors affecting on the composition and mineral content of camel milk. Moreover, she-camels grazing in extensive system (rich Savanah habitat) at Moya Mountain area give rich milk with chemical composition and minerals content compared to other systems.
