To date, camels still remain an important work animal as well as source of protein to humans in the Sudan and Sahel regions of Nigeria. Therefore, a cross-sectional study was conducted on 150 camels slaughtered in Maiduguri central abattoir to determine the prevalence of Trypanosoma evansi using Card Agglutination Test (CATT) and Polymerase Chain Reaction (PCR) techniques. Overall, 30 (20%) of the camels tested were seropositive while PCR targeting the 227 base pair of the Variable Surface Glycoprotein (VSG) gene of T. evansi detected the DNA of the parasite in 9 out of the 30seropositive camels. Higher infection was found among adult compared to the young camels using the two diagnostic techniques; 24.1% vs 19.0% and 10.3% vs 4.6%, for CATT and PCR techniques, respectively. However, the differences being not statistically significant (P > 0.05) for the two methods of diagnosis. Furthermore, significantly (P < 0.05)higher prevalence of infection was recorded among male compared to female camels using the serological method of diagnosis, while (P > 0.05) using the molecular method; 27.5% vs 13.6% for CATT and 10.1% vs 2.5% for PCR. Camels with PCV =24 %( mean: 19.8923 ± 4.0931) recorded significantly (P < 0.05) higher prevalence of 23.1% than those with PCV = 25% (mean 31.7294 ± 5.50584), where the prevalence was 17.6%.The results of this study showed that camel trypanosomosis is endemic in the study area.  Furtherstudiesto elucidate the epidemiology and socioeconomic impact of this disease in the northeast region of Nigeria are desirable.

Objective: To assess the potential hematobiochemical alterations in healthy dromedary camel during the different stages of lactation. Design: Randomized controlled study. Animals: Fifteen healthy female dromedary camels, with mean body weight of 499.6 kg and mean age of 20 years. Procedures: Camels were categorized into 3 groups' according to their stage of lactation: group 1, early lactation (1-3 months), group 2, mid-lactation (four-6 months) and group3, late lactation (≥ 7 months). Blood samples were collected from every animals for hematological and biochemical evaluation. Results: Total erythrocyte count (TEC), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), total leukocytes (TLC), lymphocytes, neutrophils, monocytes, Calcium, glucose, aspartate aminotransferase (AST), alanine transaminase (ALT), gamma glutamyl transferase (GGT) and alkaline phosphatase (ALP) confirmed significant (p < 0.05) variation between different stages of lactation. However, non-notable (p > 0.05) dissimilarity were located in packed cell volume (PCV), mean corpuscular hemoglobin concentration (MCHC), in organic phosphorus (P), magnesium (Mg), cholesterol, total protein (TP), albumen, globulin, blood urea nitrogen (BUN) and creatinine kinase (CK) in the course of different ranges of lactation, Conclusion and clinical relevance: The results of this investigation may be useful as reference guide for dromedary camel to evaluate the metabolic health status at different stages of lactation.

The quality, safety, and suitability of animal fat for processing of a specific meat product is a critical issue. Increasing the human awareness about the health aspects associated with increased intake of animal fat, makes camel fat a suitable raw material for meat processing due to its excellent nutritional contribution. Therefore, the target of this study is examination of the sensory, physicochemical, fat oxidation, fatty acid profile, and other quality parameters of camel fat to evaluate the feasibility for processing of different meat products. To achieve this goal, 30 fat samples each from the hump, renal, and mesentery of Arabian male camels were investigated. The results showed that both the renal and mesenteric fat had honey color and medium-soft texture, while the hump had greyish-white color and hard texture. The sensory panel scores were significantly different between the hump and other fats. Hump fat had significantly (P<0.05) higher moisture, protein, and collagen content, while higher fat content was recorded in mesenteric fat. The fatty acid analysis showed that hump had high SFA and very low PUFA in comparison with both renal and mesenteric fat. Camel fat had high oxidation stability, and the mean values were very low in comparison with the levels of quality and acceptability. The ultrastructural analysis showed that hump fat had high elastin fibers which increase its hardness. The results indicated that both renal and mesenteric fat were more suitable for the production of various meat products than the hump.
