“…The prevalence of mange mites was higher in female animals, 2.85% than in male animals, 0.64%, So there was a high statistical association of mange mite prevalence with the sex of animals (χ 2 = 5.17, p < 0.05). The present results show the study in agreement with the conclusion of Tefera and Gebreah (2001) , they concluded a highest disease prevalence rate in females gender, Furthermore the behaviour of breeding in males could also be recognized to the transmission of disease to a number of females.…”

Mange mites represent a serious problem in livestock farming due to their worse effect on animals health, reducing milk and meat production. The status of mange mites prevalence was unknown from the livestock present in Malakand Division, Pakistan. Hence, the present study was conducted to determine the prevalence and risk factors assessment of mange mites in livestock of Malakand Division, Pakistan. Villages and livestock herds were visited for data collection and sampling for one year from September 2017 to August 2018. The diagnosis of mange infestation was carried out from skin scrapings collected from symptomatic animals. A total of 1437 animals were screened (240 sheep, 658 cows, 340 buffalos, 199 goats) from selected localities of the Malakand Division. The overall prevalence was 2.37%, with the highest prevalence in buffalos (5.0%) and lowest (0.42%) in sheep (p < 0.05). The locality also significantly affect the prevalence of mange mites in livestock, with a higher percentage (8.14%) in the Ouch area. The prevalence was higher in winter (3.78%) than in summer (1.07%). The prevalence was high (p < 0.05) in young animals (≤1 year) (4.7%) as compared to adults (>1 year) (1.15%). Gender was also a significant risk factor for mange infestation. The infestation was higher in females (2.85%) as compared to males (0.64%) (p < 0.05). Herd size of less than ten animals had a significantly high prevalence rate (3.69%) compared to >10 animals (1.89%). Animals having an infection history >15 days infected more than animals having infection history ≤15 days. This study documented for the first-time epidemiology of mange mites in livestock of Malakand Division, Pakistan. Further studies involving molecular characterization of mange mites will increase our understanding on the spread of mange mites in Malakand Division livestock.

“…This would be due to the immature immunity of young animals ( Dinka et al, 2010 ). The present study results are in contract with the result of Tefera and Gebreah, 2001 , Dinka et al, 2010 . They concluded that the prevalence was high in young livestock animal than older ones.…”

“…The mean age of camels at first calving was 5.84±2.01 years in this study. Table 4 This is in line with the age at first calving noted in previous studies Tefera and Gebreah, 21 for eastern Ethiopia (5 years) and the Afder zone of the Somali region (5.2 years). The mean age of camels at first calving was four years in Somali Regional State Sisay.…”

The study was conducted in Mieso and Bordede districts, in West Hararghe Zone of Oromiya National Regional State with the objectives of assessing major constraints of camel production, reproductive performances, and physicochemical quality of camel milk in the study areas. A total of 120 households (camel owners) were selected purposively for interview (i.e 20 households from each kebeles). Feed shortage, conflict over the scarcity of natural resources, low productivity of grazing land, and water scarcity were the main constraints of camel production. The mean age at first mating for male and female camels was 5.92±2.91 and 4.79±1.84 years respectively, similarly, the average number of services per conception of camels in this finding was 1.73±0.64. The reproductive span of male and female camels in the study area were 20.04±6.50 and 25.20±7.83 years, respectively and the gestation period of camels recorded in this study was 1.73±0.64. The lactation length of a camel was 9.77±2.10 and 17.30±5.66 months in Mieso and Bordede, respectively. Late maturity is reported as the primary reproductive constraint followed by long calving interval, the presence of reproductive disease, low conception rate and the birth of stunted calves in Mieso district. Whereas in Bordede district the primary reproductive constraints were late maturity followed by the presence of reproductive disease, long calving interval, low conception rate and birth of stunted calf. In conclusion, camel is one of the most important livestock for pastoralists' livelihood as a source of milk, meat and draught power. In order to increase the productivity of camels, the major constraints such as shortage of feed and water, disease problems and others should be given attention.

“…The Domestic Animal Diversity Information System ( DAD-IS ) database and FAO recognize 97 camel breeds worldwide, based on distribution and specific characteristics ( http://www.fao.org/dad-is/ ). Likewise, in eastern Africa, the classification is generally based on the ethnic groups and geographical distribution of the pastoral communities that own them ( Tefera and Gebreah, 2001 ). The FAO officially recognizes 5 breeds in Ethiopia (Somali/Ogaden, Ethiopian Dromedary, Afar, Anfi, and Borena); however, pastoralists of the region recognize additional breeds ( http://www.fao.org/dad-is/ ).…”

Dromedary camels (Camelus dromedarius) are a domesticated and closely guarded economic staple of indigenous people located throughout Ethiopian territorial states. Seventeen morphometric variables were examined to determine intraspecific variation among 8 pastoralist-designated breeds of camels. Additionally, DNA sequences from mitochondrial cytochrome-b gene and genotyping of 6 nuclear microsatellite loci were examined to assess genetic diversity and phylogenetic relationship of Ethiopian camels. Examination of 525 individuals revealed significant morphometric differentiation in Afar as compared with the remaining 7 breeds. Analysis of cytochrome-b sequences failed to recover monophyletic groups associated with pastoralist-recognized breeds. Analysis of 6 microsatellite loci from 104 individuals depicted no resolution of distinct genetic lineages in accordance to geographical or designated breeds. Overall, separation of 2 ecotypes based on the morphometric data was supported; however, genetic analysis of cytochrome-b and microsatellite data failed to support any unique genetic lineage or statistically significant population structure.
