“…Daily milk yield as well as protein, lactose, and total solids contents were within the normal ranges reported in literature of dromedary camels under intensive conditions (Konuspayeva et al, 2009;Aljumaah et al, 2012a;Nagy et al, 2013). Meanwhile, milk fat content was lower than those reported by Ayadi et al (2009) and Hammadi et al (2010).…”

A total of 22 dairy dromedary camels under intensive conditions in late lactation (275±24 days) were used to study the relationship between external and internal udder morphology and machine milking performances. Measurements of udder and teat morphology were obtained immediately before milking and in duplicate. Individual milk yield, lag time and total milking time were recorded during milking, and milk samples were collected and analyzed for milk composition thereafter. Cisternal and alveolar milk volumes and composition were evaluated at 9 h milking interval. Results revealed that dairy camels had well developed udders and milk veins, with medium sized teats. On average, milk yield as well as milk fat and protein contents were 4.80±0.50 L d-1, 2.61±0.16% and 3.08±0.05%, respectively. The low fat values observed indicated incomplete milk letdown during machine milking. Lag time, and total milking time were 3.0±0.3, and 120.0±8.9s, on average, respectively. Positive correlations (p<0.05) were observed between milk yield and udder depth (r=0.37), distance between teats (r=0.57) and milk vein diameter (r=0.28), while a negative correlation was found with udder height (r=-0.25, p<0.05). Cisternal milk accounted for 11% of the total udder milk. Positive correlations were observed between total milk yield and volume of alveolar milk (r=0.98; p<0.001) as well as with volume of cisternal milk (r=0.63, p<0.05). Despite the low udder milk storage capacity observed in dairy camels, our study concluded that the evaluated dromedary sample had adequate udder morphology for machine milking. Finally, positive relationships were detected between milk yield and udder morphology traits of dairy camels.

“…The indigenous camels in Saudi Arabia are traditionally classified into four different breeds; they are Maghatier, Shu'l, Majahiem and Soffer, in which Majahiem is considered more appropriate for milk production [1,3]. Other breeds with well-developed udder are also recorded but with limited geographical distribution, they are Homor, Shaele, Sofor and Waddah (Maghatir) [4].…”

The Camel's (Camelus Dromedarius) Mammary Gland Immune System in Health and Disease

Dromedary camel (Camelus dromedarius) can survive and produce considerable amount of milk during recurrent and prolonged hot and dry environment. Camel milk considered one of the most valuable food sources due to its nutritional value. Intramammary infection and other low hygienic measurers are the main factors that undermined the camel mammary gland welfare. Available studies elaborated in detail the role of innate factors like Peptidoglycan recognition protein and Lactoferrin in camel milk as potent antimicrobial factors. Despite the wide studies on camel antibodies, their role in the mammary gland immunity was scarcely addressed. The major lack of information about the immune system of camel mammary gland is of great setback in improving the camel dairy industry. This review has evaluated the available data on different aspects of the mammary immune system. The available data unfortunately are of general profile, which created wide gaps in understanding the camel mammary gland immune system in health and disease. Several measures were proposed as necessary approaches to drive considerable interests of wide and in depth research on the camel mammary gland immune system.In conclusion, the available knowledge on the immune system of camel mammary gland suffers from major lack in the role of the immunoglobulins in health and mastitis. Although, acceptable progress was made on defining the cellular populations of the mammary gland, their main activity during the infection needs to be revealed.

This study aimed to determine the effect of management systems (farming and traditional pastoral system) and parity order on milk yield and composition of lactating Maghrebi camel. Total of forty lactating she-camels (Camelus dromedarius), (aging 5-12 years, weighing 370-590 kg, and 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 7-8parities, 5 animals in each. The obtained results revealed that overall mean of udder depth and circumference were higher (P < 0.05) in farm than pastoral system. Udder length showed (P < 0.05) an opposite trend, but udder width was not affected by management system. Overall mean of all udder measurements showed increase (P < 0.05) by advancing parity. Effect of interaction between management system and animal parity on all udder measurements was not significant. Effect of management system on all teat measurements and milk vein diameter was not significant. However, these measurements increased (P < 0.05) by advancing parity. Effect of interaction between management system and animal parity on all teat measurements and milk vein diameter was not significant. Overall mean of IgG, IgM, and IgA concentrations in colostrum of camels 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 on immunoglobulin concentrations was not significant. Daily or total milk yield was higher (P < 0.001) under farming more than pastoral system by about 26.12 and 13.41%, respectively. Fat, protein, lactose, total solids and solids not-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 yields and milk composition. 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) up to 5-6 and 3-4 parities, respectively. Yet, Mg and chlorine contents were not affected significantly by parity. The interaction between management 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.This study could be recommended to increase awareness of the nomads about the importance of the effect of feeding system and parity on yield and nutritive value of camel milk produce for human consumption or suckling t...
