Anaemia is regarded as the main pathological feature of trypanosomosis in man and animals. Trypanosomosis is ranked as a major threat for camel industry. In clinical diagnosis, values such as packed red cell volume (PCV), Hb concentration, RBCs counts and RBCs indices are used to measure the degree of anaemia and its morphology. However, in most instances, PCV alone is used to determine the degree of anaemia. There is a meager data on reference clinical parameters and haematological values of Sudanese animals including camels. This paper reports the PCV values of camels from three different States located in the camels zone as depicted from field surveys designed for camel trypanosomosis �Guffar� management and control in the Sudan. Moreover, the study discussed the effect of the disease on camels PCV. The PCV values of 362 examined camels from 19 areas in 10 localities from Kassala, Gadarif and West-Kordofan States were recorded. Thereafter, the range and the mean PCVs of the non-infected and the infected camels were determined. The mean PCV values of parasitologically infected camels were found to be significantly (p=0.000) lower than that of non-infected. Although there was no significant differences (p=0.079) between the three States in the prevalence of the disease, geographical variations have significant effect (p=0.004) on camels PCV values in this study. Based on the results of the present study as well as the difficulty of Parasitological detection and confirmation of the infection, it was concluded that PCV, can be used as clinical indicator for �Guffar� of herds at risk. This is may be helpful for strategic and effective use of trypanocides in the disease management and control. Programmed field application of this technique may also reduce the distribution of drug resistant strains of these parasites in the Country

Characteristics and Constraints of Dromedary Camel Production in South Kordofan State, Sudan
A.H. , Dhamra; E.O. , Amsaib
This study was conducted to characterize the production systems, evaluate the reproductive performances and management systems, identify the breeding goals, husbandry practices and production constraints of dromedary camels in three localities in South Kordofan State; namely; Algoz, Alkwiek and Aldalang. Through a set of detailed questionnaire, one hundred camel owners were interviewed during March and April, 2014. The study showed that 68% of the camel owners were illiterate. The respondents adopted traditional nomadic system of camel husbandry, and 53% of them preferred camels breeding compared to other livestock species. The mean age at first calving was 4.76 years, the calving interval was 23.61 months, the number of services per conception was 1.08, the age of keeping she camels was 16.87 years, the average milk yield per lactation was 1088.20 kg and the lactation length was 11.70 months. The age at first calving, milk yield and lactation length were significantly (P<0.01) influenced by locality. Aldalang Locality attained the highest values whereas the lowest values were recorded in Alkwiek Locality. However, the calving interval, number of services per conception and age for keeping she camels were not affected. The important production constraints, as defined by the respondents, were deficiency of feed, lack of security, high disease prevalence and shortage of water. It is concluded that adoption of proper husbandry practices and provision of adequate health services can play significant roles in the improvement of camel production and productivity in the State

This study was conducted at Tumbool Camel Research Center (TCRC) that embeds on the middle western edges of the Butana area (east/ central Sudan) where, sizable Arabic herd camel ecotype Darfur (western Sudan) was kept under closed moderate intensive managemental system. Monthly serum samples were collected from 8 mature female camels and three of their progeny heifers at two-year age and serum progesterone (P4) concentrations were measured. After successful mating of the mature dams P4 increased and found ranging between 7.4 to 13.8 ng/ ml. It remained elevated with pregnancy at a monthly mean of 10.85�7.12 ng/ml recording peak concentration at the 9th month of gestation (37.66 ng/ ml), and then declined to baseline concentration at parturition. She camels carried male feti were found to had insignificant lower (P>0.05) progesterone levels (10.70�5.73 ng/ml) than those carrying female feti (11.41 � 8.53 ng/ml). She-camels carrying male feti found to had insignificant lower (P>0.05) progesterone levels (10.70�5.73 ng/ml) than those carrying female feti (11.41�8.53 ng/ml). Contrarily dams carrying male and female feti respectively recorded gestation lengths of 386.67�2.67 and 382.5�2.63 days (P>0.05) respectively. Sexual activity of the camel heifers was observed to begin at 30 month old and P4 concentrations started to increase to a measurable level (1.0 -5.0 ng/ml) at 30-32 months old with detectable oesrus signs

Assessment of Bacterial Loads of Camel Milk from Farms and Sale Points in Khartoum State, Sudan

This study was carried out to evaluate raw camel milk from two sources that include farms and sale points in Khartoum State. Fifty milk samples were collected during summer and winter seasons from different farms and sale points. The milk samples were examined for total bacterial counts (TBC), coliform count and psychrotrophic count. The TBC, coliform and psychrotrophic count of camel milk samples were higher during summer season (log10 4.6�0.08, log10 3.4�0.09 and log10 0.8�0.1, respectively). Moreover, the counts of TB and coliform were higher in the milk samples collected from the dairy farms (log10 4.33�0.0 and log10, 3.1�0.09, respectively). However psychrotrophic bacteria was higher in the milk samples collected from the sale points (log10 0.9�0.16). The milk samples collected from different sources showed significant (P?0.001) differences in TBC, coliform and psychrotrophic counts. In addition, during the different seasons the bacterial loads revealed highly significant (P?0.001) differences. Generally the quality of milk obtained from farms and collection points was good, although the bacterial load was higher during summer. Hence, the study suggested that more efforts are needed to improve milk hygiene and quality by regular monitoring, raising awareness among camel�s owners and initiation of collection centers equipped with cooling facilities
