Abstract

This study aimed to determine the effect of management systems (farming and traditional pastoral system) and parity order on milk yield and composition from lactating Maghrebian she-camel in addition to its effects on somatic cell count and bacterial infection of subclinical mastitis. Total of forty lactating she-camels (camelus dromedarius) (aging 5–12 years, weighing 370-590 kg, between the first and eighth parities) were divided into two system groups (farming and pastoral, 20 in each).  Each of farming or pastoral group was divided into four sub groups according to their parity, including 1-2,3-4,5-6 and 7-8 parities ,5 animals in each. Over all mean of IgG, IgM and IgA concentrations did not differ significantly (P<0.05) under both management systems.  Concentration of IgG and IgA increased (P<0.05), while IgM insignificantly increased by advancing parity. Effect of interaction between management system and parity of immunoglobulin concentrations was not significant. Daily or total milk yield was higher (P<0.001) under farming more than pastoral system by about 20.70 and 11.75%, respectively. Fat, protein, lactose, total solids, and solid non fat contents attained significantly higher values in milk of farming than in pastoral system. However, ash content showed an opposite (P<0.001) trend. Daily and total milk yield and its composition significantly increased by advancing parity .The interaction between management system and parity was not significant on milk yield and milk compositions.  For somatic cells count the ratio was highly significant (P<0.05) in the traditional pastoral system than that recorded in farming system for collected milk samples from subclinically mastitic she-camels. Under pastoral system milk showed significantly higher contents of Na and K and significantly lower P and Mg than farm system. Milk Ca and chlorine contents were not affected by management system. By advancing animal parity, Ca and P contents increased (P<0.05), up to 7-8 parities, while Na and K increased (P<0.05), 5-6 and 3-4 parities respectively. Yet, Mg and chlorine contents were not affected significantly by parity. The interaction between management system and parity was highly significant (P<0.001) only on K and P, reflecting different trend of change in K and P contents in camels under farm and pastoral system by advancing parity. The levels of mineral contents subsequently increased with advanced ages in both systems. Our bacteriological study results revealed that S.aureus (2% and 6%), CNS (5% and 2%), E.coli (8% and 2%), S.agalactia (1% and 2%) and other Strept. (10% and 3%) were the main single bacterial isolates from all studied milk samples in both groups: traditional pastoral system and farming system respectively .Total bacterial isolates in single bacterial infections were significantly different in both systems of management (26% and 15%) respectively. Also investigations illustrated that CNS +E.coli, S.aureus + E.coli, S.aureus + other Strept., S.aureus + E.coli + other Strept. and S.aureus+ CNS+  other Strept. were the main groups of  mixed bacterial isolates in percentages of (7% and 2%), (6% and 4%), (7% and 5%), (6% and 3%) and (6% and 5%) respectively, with significant different in total mixed bacterial isolates (32% and 19%) in both traditional pastoral system and farm system respectively. There was a direct relationship between the frequency of sub-clinical mastitis and the calving number. The study could be recommended to increase awareness of the nomads about the importance of the effect of feeding system and parity in addition to bacterial isolates on yield and nutritive value of camel milk produce for human consumption or suckling their newborns.
