Foot-and-mouth disease (FMD) is widely distributed in Sudan where outbreaks occur on an annual basis especially during the winter months (December-February). This study aimed to increase our understanding of the epidemiological patterns of FMD in Sudan and connections to neighbouring countries by characterizing the genetic sequences of FMD viruses (FMDV) collected from samples collected in 10 Sudanese states over a 10-year period (between 2009 and 2018). FMDV was detected in 91 of the 265 samples using an antigen-detection ELISA. Three serotypes were detected: O (46.2%), A (34.0%), and SAT 2 (19.8%). Fifty-two of these samples were submitted for sequence analyses, generating sequences that were characterized as belonging to O/EA-3 (n = 17), A/AFRICA/G-IV (n = 23) and SAT 2/VII/Alx-12 (n = 12) viral lineages. Phylogenetic analyses provided evidence that FMDV lineages were maintained within Sudan, and also highlighted epidemiological connections to FMD outbreaks reported in neighbouring countries in East and North Africa (such as Ethiopia and Egypt). This study motivates continued FMD surveillance in Sudan to monitor the circulating viral lineages and broader initiatives to improve our understanding of the epidemiological risks in the region.

Middle East respiratory syndrome-related coronavirus (MERS-CoV) is a persistent zoonotic pathogen with frequent spillover from dromedary camels to humans in the Arabian Peninsula, resulting in limited outbreaks of MERS with a high case-fatality rate. Full genome sequence data from camel-derived MERS-CoV variants show diverse lineages circulating in domestic camels with frequent recombination. More than 90% of the available full MERS-CoV genome sequences derived from camels are from just two countries, the Kingdom of Saudi Arabia (KSA) and United Arab Emirates (UAE). In this study, we employ a novel method to amplify and sequence the partial MERS-CoV genome with high sensitivity from nasal swabs of infected camels. We recovered more than 99% of the MERS-CoV genome from field-collected samples with greater than 500 TCID50 equivalent per nasal swab from camel herds sampled in Jordan in May 2016. Our subsequent analyses of 14 camel-derived MERS-CoV genomes show a striking lack of genetic diversity circulating in Jordan camels relative to MERS-CoV genome sequences derived from large camel markets in KSA and UAE. The low genetic diversity detected in Jordan camels during our study is consistent with a lack of endemic circulation in these camel herds and reflective of data from MERS outbreaks in humans dominated by nosocomial transmission following a single introduction as reported during the 2015 MERS outbreak in South Korea. Our data suggest transmission of MERS-CoV among two camel herds in Jordan in 2016 following a single introduction event.

We evaluated growth, milk production and composition of Awassi genotypes based on 9 years data collected from the International Center for Agricultural Research in the Dry Areas (ICARDA) flock kept in Tal Hadya station, Syria (now moved to Terbol station, Lebanon). Performances of the pure genotypes (Syrian and Turkish Awassi) and the resulting crosses were compared. Growth performances did not differ among the genetic groups except for weaning weight, for which the Turkish Awassi was lighter than the Syrian Awassi and all its crosses; the 75% Syrian genotype being the heaviest (19.54±0.43 kg). Genetic groups did not differ (p>0.05) for both lactation length (overall mean 100.39±1.20 days) and lactation milk yield (overall mean 91.2±2.50 kg). Lactation yields of milk constituents (fat, protein, lactose, total solids and solids-not-fat) were, however, higher for the 75% Syrian crosses compared to the other crosses as well as to the pure Awassi sheep, except for lactation protein yield. The performances of Turkish Awassi were not superior to those of the Syrian genotype for all the traits considered under the environmental conditions of Syria. It is concluded that the Turkish Awassi should not be used as an improver breed for the Syrian genotype. The performance of the ICARDA maintained Awassi flock has on average been better compared to those of other farms in the region. Improved rams produced from the breeding program could therefore serve as improver for flocks maintained in countries of the region, necessitating the development of appropriate delivery systems of improved genetics.

The authors describe the goat markets in Afghanistan by analyzing goat producers’ price expectations and by identifying the factors that determine these price expectations. Data on expected prices for goats transacted were collected from 280 goat producers from Baghlan and Nangarhar provinces, along with information on factors anticipated to influence the price expectation from May 2008 to April 2009. A price expectation model was built and analyzed using a general linear model. Results indicated that goat producers adjusted expected prices for marketing day (Saturday and Thursday), location of sales (district and provincial markets), live weight, and goat producers’ market network. However, goat producers did not expect a premium for goat attributes like breed and age. The implications of the study are that goat producers can expect more when they plan their goat sales based on live weight, market day, marketing place and sex of goat.

A survey was conducted to study the morphological characteristics of indigenous goats in representative zones and districts of Amhara Region of Ethiopia as a first step towards characterization and designing of breeding programs. A pre-tested questionnaire was used for recording morphological features, body weights and linear body measurements. Both qualitative and quantitative traits were recorded on 158 goats randomly sampled from six goat populations and the data were analyzed using GenStat version 13 software. Live body weights were also associated and predicted using linear body measurements. Results confirmed that six distinct indigenous goat populations were identified and characterized in the region viz. Gumuz, Begia-Medir, Agew, Bati, Central Abergelle and Abergelle. There were clear morphological variations between and within these goat ecotypes in terms of body coat color, head profile, horn orientation, ear form and head shape. The Ethiopian goat ecotypes found in Amhara Region of Ethiopia could be clustered into two main groups viz. Gumuz, Agew and Begia-Medir cluster as one group and Bati, Abergelle and Central Abergelle as the second group. The high variations observed in the morphological traits suggest that these goat ecotypes have not yet been selected through structured selective breeding. The high correlation coefficients of heart girth with body weight for west (r = 0.899) and east (r = 0.832) Amhara Region goat populations demonstrated a strong relationship between these variables with regression equations of y = 1.273x – 61.329, R² = 0.807 and y = 0.486 x – 5.798, R² = 0.095, respectively, which allows for predicting live weight from heart girth in these goats. In general, the observed morphological characteristics of the goats’ genetic resources in Amhara region together with the characterization at molecular level will contribute to designing of improvement strategies for these goat populations, which will need to be complemented with performance data.

The genetic variation in Hamdani sheep in the Kurdistan region of Iraq was studied using 35 microsatellite markers. All 35 markers were found to be highly polymorphic. The mean number of observed alleles ranged from four at BMS1494 to twenty five at BM6444 and INRABERN185 loci. The polymorphic information content (PIC) values ranged from 0.208 for BMS1494 loci to 0.935 for INRABERN185 with an average value of 0.744. The overall observed and expected heterozygosity values were 0.407 and 0.764, respectively. Test of genotype frequencies for deviation from the Hardy-Weinberg equilibrium (HWE) at each locus, revealed a significant departure from HWE due to loss in heterozygotes by high level of inbreeding. The average inbreeding value for the 35 markers investigated was 0.469. The high observed heterozygosity is an indication of genetic variability that could be used for developing efficient utilization and genetic improvement strategies for Hamdani sheep. Key words: Hamdani sheep, microsatellites, polymorphism, genetic diversity, inbreeding, heterozygosity.

Identification of breeding objective traits pertinent to specific production environments with the involvement of target beneficiaries is crucial to the success of a breed improvement program. A choice experiment was conducted in four locations representing different production systems and agro-ecologies that are habitat to four indigenous sheep breeds (Afar, Bonga, Horro and Menz) of Ethiopia with the objective of identifying farmers’/pastoralists’ preferences for sheep breeding traits. Following a synthesis of secondary information and diagnostic surveys, two communities per location consisting of 60 households each having at least four breeding ewes were identified. Producers’ priority attributes used in the choice sets were identified through in-depth production system studies conducted from December 2007 to March 2008. On the basis of prior information, four to seven attributes were used to design choice sets with different profiles in order to capture results that mimic real life of the different communities. The attributes and levels chosen for the sheep profile were as follows: body size (large/small), coat color (brown/white/black), tail type (good/bad) for both rams and ewes; horn (polled/horned) and libido (active/poor) for rams; and lambing interval (three lambings in 2 years/two lambings in 2 years time), mothering ability (good mother/bad mother), twinning rate (twin bearer/single bearer) and milk yield (two cups per milking/one cup per milking) for ewes. A fractional factorial design was implemented to construct the alternatives included in the choice sets. The design resulted in a randomized selection of 48 sheep profiles (24 sets) for both sexes, which were grouped into four blocks with six choice sets each. An individual respondent was presented with one of the four blocks to make his/her choices. Results indicate that producers’ trait preferences were heterogeneous except for body size in rams and mothering ability in ewes where nearly homogeneous preferences were investigated. In the pastoral production system, attention was given to coat color of both breeding rams and ewes, favoring brown and white colors over black. Ram libido influenced producers’ decisions in Bonga, Horro and Menz areas. The influence of milk yield and twinning on respondents’ decision making was high in Afar and Horro, respectively. Breeders in all areas attempt to combine production and reproduction traits as well as they can in order to maximize benefits from their sheep. The elicited measurable objective traits were used to design alternative community-based sheep breeding plans for the four indigenous sheep breeds in their production environments that have been implemented since.

Designing breeding schemes suitable for smallholder livestock production systems in developing regions has hitherto been a challenge. The suggested schemes either do not address farmers' breeding goals (centralized station-based nucleus schemes) or yield slow genetic progress (village-based schemes). A new breeding scheme that integrates the merits of previously suggested schemes has been designed for Menz sheep improvement in Ethiopia. It involves selection based on breeding values in nucleus flocks to produce elite rams, a one-time only provision of improved rams to villagers and a follow-up village-based selection to sustain genetic progress in village flocks. Here, we assessed whether conventional selection of breeding rams based on breeding values for production traits, which is the practice in station-based nucleus flocks, meets farmers' breeding objectives. We also elicited determinants of farmers' ram choice. Low but significant correlations were found between rankings of rams based on farmers' selection criteria, estimated breeding values (EBV) and body weight (BW). Appearance traits (such as color and horn) and meat production traits (BW and linear size traits) significantly determined farmers' breeding ram choice. The results imply that conventional selection criteria based solely on EBV for production traits do not address farmers' trait preferences fully, but only partially. Thus, a two-stage selection procedure involving selection on breeding values in nucleus centers followed by farmers' selection among top- ranking candidate rams is recommended. This approach accommodates farmers' preferences and speeds up genetic progress in village-based selection. The Menz sheep scheme could be applied elsewhere with similar situations to transform conventional station-based nucleus breeding activities into participatory breeding programs.

Sheko is African taurine cattle, valued for its milk yield, adaptation to humid tsetse infested environment and trypanotolerance. We used 30 microsatellite markers in analyzing 30 DNA samples. We found high genetic diversity and no genetic bottlenecks in endangered Sheko cattle. Sheko cattle have not undergone recent genetic bottlenecks, in spite of drastic reduction in its overall demographic population size. The results were supported by three statistical methods: (i) detection of heterozygosity excess (ii) a mode-shift indicator of allele distribution pattern (iii) the ratio of the number of alleles to the range of allele size, M-ratio test. This breed reflects historical and cultural identity of local communities and represents a unique component of the global domestic animal biodiversity that deserve priority for conservation.

Rift Valley Fever (RVF), an insect-borne viral zoonotic disease caused by a member of the Phlebovirus genus of the family Bunyaviridae, was first recognised in the Rift Valley of Kenya in the early 1930s. Since then, several epidemics of RVF have occurred in northern, southern and now eastern Africa becoming a continental problem. The epidemics that occurred in Egypt in 1977-78 and recent human and livestock cases in Yemen and Saudi Arabia (in September 2000) indicated the potential for the disease to spread to other inter-tropical regions of the world outside African continent. An embargo on livestock export by Gulf countries has brought in food insecurity in the East African countries due to indirect socio-economic mechanisms and impact of the ban on pastoralists household economy. Though food insecurity in the Horn of Africa is a longstanding problem, the recent bans imposed on eight countries, which are not yet recovered from the effects of recent droughts has further exacerbated the situation. Between September and December 2000, livestock export dropped by 92% in Somalia. According to FSAU/FEWS (2001), the estimated total loss of income at the Somali owner/producer level (including livestock originated from eastern Ethiopia), reached 20-30 millions of USD. This figure does not include the reduced government revenue from livestock trade taxes. In Somalia, about 80% of foreign exchange earned from livestock exports are used to import basic food items and other commodities. The effect of livestock export ban was further compounded due to the decrease in imported commodities. This review emphasises on epidemiology and risk of RVF, and the impact on the future of the livestock economy and pastoralists household economy in the Horn of Africa; underscores the consequence on food security; analyses the current situation in a region already with multifaceted crises viewed against international experience; and forward recommendations to the problem associated with RVF.

Technological interventions aiming to improve livelihoods that bring gender equity can become successful only when the prevailing gender roles in society and access to different livelihood opportunities are fully understood. This article analyses gender roles in agriculture in the conservative patriarchal society of Afghanistan. Rapid appraisal was conducted through focus group interviews, participatory resource mapping, and so on, in seven villages each from Nangarhar and Baghlan provinces of Afghanistan. Educated women coordinators, facilitators and activists and well established womens’ groups were used to reach and target key women informants as they are not allowed to interact directly with male researchers. Their participation was more in livestock related activities. The study indicated that women’s involvement was less than men’s in both livestock and crop related activities. Age, social stigmas, poverty and shortage of labour influence the gender division of labour, decision-making ability and participation in Afghanistan’s farm and non-farm activities. This indicates that any agricultural development programme intending to involve women will be effective only if it has a large component of livestock related activities.

The genetic trends in fitness (inbreeding, fertility and survival) of a closed nucleus flock of Menz sheep under selection during ten years for increased body weight were investigated to evaluate the consequences of selection for body weight on fitness. A mate selection tool was used to optimize in retrospect the actual selection and matings conducted over the project period to assess if the observed genetic gains in body weight could have been achieved with a reduced level of inbreeding. In the actual selection, the genetic trends for yearling weight, fertility of ewes and survival of lambs were 0.81 kg, -0.00026% and 0.016% per generation. The average inbreeding coefficient remained zero for the first few generations and then tended to increase over generations. The genetic gains achieved with the optimized retrospective selection and matings were highly comparable with the observed values, the correlation between the average breeding values of lambs born from the actual and optimized matings over the years being 0.99. However, the level of inbreeding with the optimized mate selections remained zero until late in the years of selection. Our results suggest that an optimal selection strategy that considers both genetic merits and coancestry of mates should be adopted to sustain the Menz sheep breeding program.
