“…The increase in average daily milk yield amounted to 53% under semi-intensive system compared to those under traditional system. The present values of milk composition are in agreement with the results of (Abdalla et al), who reported that milk of Maghrebi she-camels under normal condition contained 3.01, 3.06, 0.69, 4.33, and 11.06%for protein, fat, ash, lactose and total solids contents, respectively [41]. Also, Obied and Hakem found a wide range of variation in the chemical composition of milk among different management systems especially under uncontrolled environmental condition as is mostly the case locally and the significant effect between the mean values of the two milk groups at (P < 0.05) were found to be in water, lactose, ash and total solids [42].…”

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...

“…The highest daily milk yield was recorded in the early and mid-stages, while the lowest was obtained in the late stage of lactation. The variation of the daily milk yield throughout lactation in our study followed the typical trend observed in previous works (Musaad et al, 2013;Abdalla et al, 2015). The fat content increased progressively as lactation advanced.…”

This study aimed to investigate the impact of management system and lactation stage on camel milk fatty acid (FA) composition, with emphasis on odd and branched-chain FA (OBCFA), conjugated linoleic acids (CLA), and trans-FA (TFA). Milk samples were collected from thirteen camels managed under intensive and semi-intensive systems at early, mid, and late lactation. Our results provided for the first time the OBCFA profile in camel milk. Eleven OBCFA were identified with a predominance of C15:0, anteiso-C15:0, anteiso-C17:0, and C17:0. The vaccenic acid (VA) was the predominant TFA; other isomers appeared in smaller amounts. The Δ9-desaturase activity measured as desaturation index of C14:0 was relatively high in the mammary gland of camel. Milk from the semi-intensive system was characterized by a higher nutritional value, due to the higher contents of total CLA, rumenic acid (RA), VA, linoleic, α-linolenic, and polyunsaturated FA compared with milk from the intensive system. Few differences were found in the OBCFA profile throughout lactation. Our study provided deeper information on FA composition, showing that camel milk is a good source of OBCFA, RA and VA. These results have to be taken into account in the investigation of the functional properties of camel milk fat as well as in the ongoing intensification of camel farming systems.

“…Inconsistent of cattle, dromedary camels are seasonally breed animals (Allam et al 2013), have a long pregnancy period (13 months), give a single calve every two years (Jianlin 2011). Moreover, Abdalla et al (2015) reported that camels have a wide range of milk production (3.5-20 kg/d). Therefore, it was recommended to make a selection for this species.…”

Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter). Meanwhile, Fetal Dromedary Camel Serum (FDCS) was obtained from camel fetuses after slaughtering. Thereafter, only Cumulus Oocyte Complexes (COCs) were matured in vitro in the Tissue Culture Medium (TCM-199) complemented with 10% FDCS. Spermatozoa required for in vitro fertilization were collected from testes (epididymal cauda) of the slaughtered camel bulls. The results clearly showed that the maturation rate of oocytes at metaphase II was about 59.5% while the fertilization rate was around 70.4%. Intriguingly, the embryo rates determined were 13.1%, in 2-cell; 0.0%, in 4-cell; 34.7%, in 8-16% cell; 39.1%, in morula and 13.1% in a blastocyst stage. This study represented a successful in vitro production of Sudanese dromedary camel embryos from epididymal sperm cells and in vitro matured oocytes recovered from slaughtered camels.
