Comparison of methodologies for estimating enteric methane emission factors from sheep in smallholder systems in Africa: A case study from Ethiopia

In Ethiopia, enteric methane emissions from sheep contribute around 7 % to the national greenhouse gas (GHG) budget. This study examined the gross energy intake (GEI) and enteric methane emission factors (EFs) of sheep in smallholder systems in North Shewa, Ethiopia, using locally derived data via household surveys. The surveys encompassed two agroecological zones (AEZs) and analyzed various sheep classes across seasons. The study followed the Commonwealth Scientific Industrial Research Organization (CSIRO) Tier 2 methodology, which had previously been used in Kenya, and compared the results with those derived from the 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Tier 2) methodology. The EFs from the two Tier 2 methodologies were compared with IPCC default Tier 1 EF. The ranges of GEI and EF estimated for the different sheep classes showed similarity with larger variations observed for IPCC Tier 2 estimates. The estimated GEI for the various sheep classes ranged from 11.1 to 13.8 MJ day−1 (‘CSIRO’ Tier 2) and 10.2–14.7 MJ day−1 (IPCC Tier 2). The estimated EFs ranged from 4.8 to 5.9 kg CH4 animal−1 year−1 (‘CSIRO’ Tier 2) and 4.5–6.5 kg CH4 animal−1 year−1 (IPCC Tier 2). The flock-level EF was computed by aggregating the EFs of the different sheep categories. The flock level EF estimated by the IPCC Tier 2 (6.0 ± 0.1 kg CH4 animal−1 year−1) was significantly higher compared to both the 'CSIRO' Tier 2 and IPCC Tier 1 methods. Based on the findings, we can say that variations in EF values emphasize the significance of taking different Tier 2 approaches into account when evaluating and comparing CH4 emissions estimates in smallholder sheep farming systems. However, there is a need for further investigations to compare the two Tier 2 methodologies against actual intake and emission measurements to decide which methodology is better.

Molecular Characterization and Antimicrobial Susceptibilities of Corynebacterium pseudotuberculosis Isolated from Caseous Lymphadenitis of Smallholder Sheep and Goats.

Caseous lymphadenitis (CLA) is a bacterial infection caused by Corynebacterium pseudotuberculosis (C. pseudotuberculosis) that affects sheep and goats, leading to abscess formation in their lymph nodes. The present study aimed to isolate and identify C. pseudotuberculosis from CLA in smallholder sheep and goats, and determine the resistance patterns, virulence, and resistance genes of the isolates. Additionally, genotypic and phylogenetic analysis of the isolates was conducted using ERIC-PCR and DNA sequencing techniques. A cross-sectional study examined 220 animals (130 sheep and 90 goats) from 39 smallholder flocks for clinical signs of CLA. Fifty-four (24.54%) animals showed CLA-compatible lesions, confirmed by C. pseudotuberculosis isolation and PCR identification. Sheep had a lower infection rate of CLA (18.46%) compared with goats (33.3%). Antimicrobial susceptibility testing of 54 C. pseudotuberculosis isolates to 24 antimicrobial drugs revealed that they were 100% resistant to bacitracin and florfenicol, while none of the isolates were resistant to norfloxacin. A high resistance rate was observed for penicillin and erythromycin (92.6% each). Interestingly, 16.7% of C. pseudotuberculosis isolates recovered from sheep showed vancomycin resistance. Molecular characterization of C. pseudotuberculosis isolates revealed that PLD, PIP, and FagA virulence genes were present in all examined isolates. However, the FagB, FagC, and FagD genes were detected in 24 (100%), 20 (83%), and 18 (75%) of the sheep isolates, and 26 (87%), 26 (87%), and 18 (60%) of the goat isolates, respectively. The β-lactam resistance gene was present in all isolates. Furthermore, 83% of the sheep isolates carried the aminoglycoside (aph(3″)-lb), chloramphenicol (cat1), and bacitracin (bcrA) resistance genes. Among the isolates recovered from goats, 73% were found to contain macrolides (ermX), sulfonamide (sul1), and bacitracin (bcrA) resistance genes. It is worrisome that the glycopeptide (vanA) resistance gene was detected in 8% of the sheep isolates as a first report. ERIC-PCR genotyping of 10 multi-drug-resistant C. pseudotuberculosis isolates showed a high similarity index of 83.6% between isolates from sheep and goats. Nucleotide sequence analysis of partial 16S rRNA sequences of C. pseudotuberculosis revealed 98.83% similarity with biovar Ovis of globally available reference sequences on the Genbank database. Overall, our findings might indicate that C. pseudotuberculosis infection in smallholders in Egypt might be underestimated despite the significant financial impact on animal husbandry and potential health hazards it poses. Moreover, this study highlights the importance of implementing a sustainable control strategy and increasing knowledge and awareness among smallholder breeders to mitigate the economic impact of CLA.

PARASITES AND ANTHELMINTIC RESISTANCE CONTROL MEASURES FOR SMALL RUMINANT GASTROINTESTINAL NEMATODES

The greatest prevalence of gastrointestinal nematode infection in the small holder sheep and goat flocks. Sheep and goat flocks in the Cuddalore area had a higher incidence of gastrointestinal nematode infection during the rainy season, notably during the north east monsoon, than at any other time of year. Haemonchus spp., Trichostrongylus spp., Oesophagostomum spp., and Bunostomum spp. were the most often found gastrointestinal nematodes in the small holder sheep and goat flocks in the Cuddalore area. In all the small holder sheep and goat flocks in the Cuddalore area, the mean faecal egg counts of gastrointestinal nematodes were found to be highest during the rainy season, followed by winter and summer

Traditional sheep breeding practices under agroforestry system of Gedeo zone, Southern Ethiopia.

The study was undertaken in Gedeo zone with the aim to identify traditional sheep breeding practices. Three potential districts (Yirgachefe, Bule and Gedeb) were purposely selected from Gedeo zone. A total of 180 smallholder sheep farmers were selected at random to complete a structured questionnaire that had been pretested. A pairwise ranking tool was used to prioritize ranked data during focus group discussion. Descriptive statistics were generated using SPSS version 26, while indices were computed for the ranked data. Mating happens because most farmers in Gedeo zone (80%) own breeding rams that are mixed and run with ewe flocks. Fifty-two percent of farmers were certain that their breeding rams mate with neighboring ewes. Nearly 70% of farmers prevented unwanted sheep breeding in their flocks by castrating or isolating undesirable rams from the ewe flock. Undesired or old breeding rams were replaced either from the same flock (58.9%) or purchased from local markets (41.1%). Breeding flock selection was common in Gedeo zone, with 97.2% of farmers selecting breeding rams and 93.3% of farmers selecting breeding ewes. Genotype (Index = 0.26) and body conformation (Index = 0.20) were the primary and secondary criteria used to select breeding ewes. Likewise, confirmation (Index = 0.25), genotype (Index = 0.24) and lamb growth rate (Index = 0.19) were the top three criteria when selecting breeding rams. Approximately three-quarters of interviewed farmers culled sheep due to poor body condition (31.8%), old age (28.6%), sickness (22.7%) and sterility (15.6%). Castration of rams was more common in Gedeb (58.3%) and Yirgachefe (55%) districts, and it was done for fattening, controlling unwanted breeding, and improving temperament. The mean selection and castration age of breeding rams were 13.18 and 30.72 months. In general, sheep breeding strategies for Gedeo zone should take into account section preferences and basic traditional sheep breeding practices.

Factors Affecting Small-Scale Livestock Farming in Kenya

Purpose: This study aims at examining the factors influencing small-scale livestock farming in Kenya.
 Findings: A majority of the small-scale livestock farmers in many counties were past their youthful years, with most respondents cited at above fifty years. The study found out that 56% of the farmers in some counties showed the most aggression in seeking out livestock farming related information from many other sources other than from their counterpart farmers. These farmers quest for extensive information on dairy farming was also highlighted by their expansive peer to peer networks.
 Unique Contribution to Theory and Practices: Counties should make more commonage land available to the small-scale livestock farmers in order to cope with the increasing population of emerging farmers. Commonage land management should be strengthened. Small-scale livestock farmers should be trained to make reserves such as hay and silage so they can conserve surplus forage in rainy seasons. Government should provide subsidies for purchase of breeding stock and dosing products. Distribution policies that will ensure that all smallholder cattle and sheep farmers at grassroots level benefit should also be put in place.

Smallholder sheep farmers’ perception of production constraints and competitiveness strategies in South Africa

Sheep production in South Africa has experienced some growth though very slow, and as such production cannot meet demand in the local market. This study aimed to determine the factor influencing the competitiveness of smallholder sheep farmers’ and constraints faced by sheep farmers in South Africa. A farm-level cross-sectional data of 217 smallholder livestock farmers in South Africa were used to identify the factors influencing the competitiveness of smallholder sheep farmers in South Africa. The Porter's Diamond Model Framework was used to measure the competitiveness of sheep production in the study areas and principal component analysis was applied to assess the constraints faced by sheep farmers. The study results found that smallholder sheep farmers in the study area are faced with numerous production constraints, which inhibit their productivity and competitiveness. The most severe constraints include marketing, stock theft, lack of capital, diseases and parasite, and high feed cost. The study suggest that smallholder sheep farmers in the study areas can be competitive and experience growth through the creation of agribusiness enabling environments by promoting policies and strategies that will boost investments in sheep production across the value chain.

Effects of Supplementing Finger Millet (<i>Eleucine coracana</i>) Straw with Grass Pea (<i>Lathyrus sativus</i> L.) Hulls and Concentrate Mixture on Feed Intake, Digestibility and Body Weight Change in Washera Sheep

The productivity of sheep in Ethiopia is very low mainly due to a serious shortage of feedstuff. As a result, it is necessary to look for cheap locally available feedstuffs to sustain sheep production in the country. Non-conventional feeds like grass pea (Lathyrus sativus L.) hulls (GPH) could partly fill the gap in the feed supply, decrease competition for food between humans and animals and reduce feed cost. Therefore, this experiment was designed to evaluate effects of different proportions of grass pea hulls and concentrate mixture (CM) supplementation on feed intake, digestibility, and growth of Washera sheep fed finger millet straw (FMS) as a basal diet. Diets consisted FMS alone fed ad libitum (T1), 100% CM (T2), 30% GPH mixed with 70% CM (T3), 30% CM mixed with 70% GPH (T4), and 100% GPH (T5). For all treatments, FMS was fed ad libitum. Experimental sheep were arranged in a randomized complete block design and treatment feeds were assigned to the animals within a block. The results showed that FMS contained 5.5% CP and 68.9% NDF. The supplements contained 21%, 20%, 16% and 14% CP; and 36%, 43%, 52% and 59% NDF for T2, T3, T4 and T5, respectively. Supplementation improved (p resulted in the lowest ADG (p . While, animals in T1 lost a bodyweight of 5.6 g/day. As the proportion of GPH supplementation was greater than 30%, there was reduction (p T2 > T4 > T5. Therefore, from biological point of view as well as based on partial budget analysis, T3 was found to be recommendable for smallholder sheep producers.

Major Causes of Calf and Lamb Mortality and Morbidity and Associated Risk Factors in the Mixed Crop-Livestock Production System in Jamma District, South Wollo, Ethiopia

Lamb and calf preweaning mortality and morbidity account for serious losses in sheep and cattle production and are, thus, a major factor in reducing profitability and adversely affecting the sheep and cattle farming. Thus, a prospective cohort study was conducted in Jamma district, Amhara Regional State, to determine the major cause of calf and lamb morbidity and mortality and associated risk factors. A semi-structured questionnaire and clinical assessment of the animals were conducted from 150 households to assess the potential risk factors. Besides, a total of 102 (81 fecal samples and 21 skin scrapings) were collected from 150 clinically ill and suspected animals to identify the cause of morbidity and mortality. The test of difference and correlation between variables were computed using chi-square and generalized linear model analysis. The total morbidity and mortality in calves were 33.3% and 2%, respectively, whereas for lamb, they were 27.3% and 32.5%, respectively. In calf, septicemia (100%) was a major cause of mortality, and diarrhea (54.6%) was the leading cause of calf morbidity followed by skin disease (30.1%), respiratory problems (12%), and septicemia (3.3%). Malnutrition was the most common problem in lambs causing up to 31.3% mortality followed by diarrhea 24% and respiratory problems 21.3%. The presence of a disease in adult cattle was significantly correlated to the presence of disease in calves (p < 0.001; r = 0.35). There was also a significantly higher positive correlation between sickness in adult sheep and lambs (p < 0.001, r = 0.45). Gastrointestinal parasitosis was identified in 82.7% of the samples collected from diarrheic and suspected calves (87.1% positive) and lambs (80% positive). Monezia species in lamb (33.3%) and Coccidia species in the calf (35.9%) had the largest morbidity rate. Ctenocephalides canis (16.7%) and Linognatus species (41.7%) were common ectoparasites identified in calves, while Melophagus ovinus was the only ectoparasite of lambs recovered (62.5%). In conclusion, the high morbidity found in calves and morbidity and mortality in lambs are known to seriously reduce the profitability of the smallholder cattle and sheep production in the area by affecting the availability of replacement animals and causing a detrimental effect on herd expansion and productivity. In further studies, establishing the specific causative agents, control of diseases in the adult, and improvement in feed resources should be the major areas that need to be considered to mitigate calf and lamb morbidity and mortality currently affecting the area.

Determinants of profit efficiency among smallholder sheep farmers in South Africa

Livestock production contributes significantly to the agricultural sector in South African partly because it is a source of cash income especially for smallholder farmers who depend on agriculture for their livelihood. This article analyzes the competitiveness and profitability of smallholder livestock farmers and its impacts on their livelihood in South Africa. We applied the stochastic profit frontier approach to account for the factors influencing the productivity of sheep production and the profit efficiency of the farmers. The results of our analysis show that education and household size increase the profitability of the farmers while gender (female) and sheep loss negatively influence the profitability of the farmers. The average profitability (profit efficiency) score was estimated at 65.5% meaning that an estimated 34.9% of the profitability is lost due to the combination of technical and allocative efficiencies in production. This implies that the smallholder farmers are not producing at full capacity and thus have the ability to increase production, profitability, and their competitiveness in the farmers. Education and training and technological innovation in production can increase the profitability of the farmers.

CHARACTERISTICS OF SMALLHOLDER SHEEP AND GOAT MANAGEMENT PRACTICES IN SOUTH EAST NIGERIA: OBSERVATIONS FROM ANAMBRA STATE

This paper presents the results of a survey of sheep and goat producers in Anambra State, (present day Enugu and Anambra State), Nigeria. The sampled areas represent the agroclimatic and administrative zones of the oid Anambra State. A total sample size of 310 spread over 5 LGAS and 25 village areas was drawn. Only households which kept sheep and/or goats at the time of the study were sampled. Data generated included demographic characteristics of small stock owners, sheep and goat distribution by household, management practices and problems associated with current management systems, sources of feed by season and livestock disease profile. Results of analyses showed that ownership distribution of animals was skewed in favour of goats. The mean flock size per household was 2.4 and 6.2 sheep and goats respectively. About 22% of the households interviewed kept sheep alone, another 62% kept goats alone. Over 85% of respondents acquired their foundation stock from the open market, while others came from neighbours flocks. Most respondents expressed the desire to increase their holdings with more wishing to expand their goat herd size than sheep. However, feeding was most frequently mentioned as a limiting factor in increasing sheep or goat herd size. Household wastes and cut forages were the major sources of animal feed. There was a very low awareness level of agroforestry practices, Only 5.2% and 2.3% of the respondents had any knowledge of Intensive Feed Gardening (IFG) and Alley farming (AF) respectively. Reported Smallholder Sheep and Goats Management mortality was low less than 3.5% in all herds studied). Implications for improved small ruminant production in Nigeria's humid zone are drawn.

Medicinal plants used for diarrhoea treatment in sheep and goats among smallholders in farm settlements of Ogun state, Nigeria

The use of traditional remedies in the treatment of diarrhoea in ruminants is a common form of therapy among poor resource smallholder farmers in Nigeria with restricted access to veterinary healthcare services. The medicinal plants of antidiarrheal importance in smallholder sheep and goat production systems were studied in farm settlements namely Ado-Odo, Ikenne and Ibiade, located in Ogun state, Nigeria. Techniques including interviews, observations and guided field walks were used to collect data from 150 farmers across the farm settlements. Results showed that all respondents owned either sheep or goats with goats more preferred, while diarrhea was also observed to be a major disease problem in goats compared to sheep. About 92% of the farmers admitted using anti-diarrhoea herbs and about 80% agreed to their effectiveness in the treatment of diarrhoea in sheep and goats. The study identified 11 plant species used to treat diarrhoea with varied recipe and the route of administration was orally. Less than 12% of these plant parts were administered solely, preparing as a single-component while the majority of the identified plants were used in combination with other plant parts. Phytochemical components were analyzed for tannin, saponin, flavonoid and alkaloid which were observed in different plant parts showing their potential as antidiarrheal agents.The usage of these plants could therefore be an indispensable component of traditional medicine practice which can serve as safe alternative and complementary medicines to various allopathic drugs that could help safeguard health and obtain optimum production from animals.&#x0D;

Smallholder sheep farmers’ perceived impact of water scarcity in the dry ecozones of South Africa: Determinants and response strategies

Water scarcity is amongst the major challenges threatening smallholder sheep production in subsistence-oriented communal farms in dryland areas. Local contextual factors are a prerequisite for effective policy development and optimisation of water resources management for smallholder sheep production. Two-hundred and fifty-two structured questionnaires were administered to investigate the contextual factors that influence smallholder farmers’ perceived impact of water scarcity on sheep production in the dry ecozones of the Cape provinces in South Africa and identify their local response strategies. Logit regression findings showed that a unit increase in private commercially-oriented arid farms, males, education level, flock size, adapted breeds and income from livestock increased farmers’ probability to perceive impact of water scarcity on sheep production. Regardless of ecozone and farm types, sheep farmers switched between water sources, provided supplementary feed and shade, used adapted breeds and alternative markets to manage the impact of water scarcity. Interventions to build resilience to water scarcity in the surveyed areas should target sheep farmers with low adaptive capacity, particularly less educated women relying on livestock income and farming with non-adapted breeds on subsistence-oriented communal farms in the semiarid ecozone.

Factors affecting the intensity of market participation of smallholder sheep producers in northern Ethiopia: Poisson regression approach

Sheep marketing is playing a great role in improving the livelihoods of smallholder farmers in Ethiopia. Although it plays a great role, the smallholder farmers are not sufficiently participating i...

Risk Factors and Severity of Gastrointestinal Parasites in Selected Small Ruminants from Malaysia.

The productivity of smallholder sheep and goat flocks is constrained by high morbidity and mortality of young stock due to helminthosis and coccidiosis. We hypothesized that gastrointestinal parasites are prevalent and may cause severe infections amongst small ruminants in Malaysia. A cross-sectional survey was conducted between March and December 2019 to investigate the prevalence, risk factors, and levels of infection with gastrointestinal strongyle and coccidia in selected smallholder goat flocks in Negeri Sembilan, Malaysia. A total of 257 blood and fecal samples and management data were collected from four farms in Negeri Sembilan. Gastrointestinal parasites were detected by routine sodium chloride floatation, and the McMaster technique was used to quantify the fecal eggs/oocysts per gram outputs (EPG/OPG). The severity of infection was classified as mild (50–799), moderate (800–1200), or severe (>1200). The packed cell volume (PCV) was determined by microhematocrit centrifugation and classified as anemic or non-anemic. Coprological examination revealed an overall prevalence of 78.6% (CI = 72.74–83.44) and 100% flock level prevalence of strongyle and coccidia infection among goats from Negeri Sembilan with a higher infection in flock A-Lenggeng (95.6%) than B-Senawang (87.3%), D-Mendom (80.6%), or C-Seremban (60.0%). The co-infections of strongyle + Eimeria (50.6; CI = 44.50 to 56.64) were more common than single infections of either strongyle (16.7%; CI = 12.66 to 21.78) or Eimeria (4.3%; CI = 2.41 to 7.50). Quantitative analysis has revealed different (p < 0.05) patterns of EPG/OPG in various categories of goats. In total, there were 49.8% mild, 8.6% moderate, and 13.6% severe infections of strongyle and 40.1% mild, 6.6% moderate, and 19.8% severe infections of coccidia among goats. The mean PCV of goats with severe strongyle infection (24.60 ± 0.85) was significantly (p < 0.05) lower than the moderate (26.90 ± 1.15), or mild (28.23 ± 0.50) infections and the uninfected (30.4 ± 0.71). There were increased odds of infection with strongyle and coccidia among female (OR = 3.2) and adult (OR = 11.0) goats from smallholder flocks in Negeri Sembilan. In conclusion, gastrointestinal strongyles and coccidia occur at high frequency among smallholder goats, and there is a higher risk of infection amongst the adult and female stock.

Sheep and goat farming in Imo state Southeast Nigeria: A traditional vocation at the verge of extinction?

Since prehistoric times, sheep and goat farming has been an integral part of the farming system of the people of South east Nigeria. This study investigated the current state of sheep and goat farming amongst households in Imo State south eastern Nigeria. A total of one hundred and fifty (150) structured questionnaires were distributed to farmers randomly selected from three Local Government Areas (LGAs) in Imo state namely, Oru West, Ahiazu Mbaise and Ezinihitte Mbaise to determine the socio-economic characteristics, production systems, breeding and reproduction, constraints and strategies for economic improvement in a focus group interview. Only 89 farmers were available for interview. The results revealed significant decline in sheep and goat farming amongst the households across four generations within the households interviewed. Lack of interest due to poor policy framework, low productivity of existing breeds, difficulty in feed supply and high cost of breeding stock was identified as constraints of sheep and goat production in thiese areas. It was also observed that older people were more directly involved in sheep and goat farming than youths. 59.6% of the farmers were females, and 31-50% of the farmers were between the ages of 31 and 50 years. Farming was the most common occupation amongst the households while trading was the next. Results also showed that 76.4% of the communities had history of sheep and goat keeping whereas 73% of the total families interviewed had a history of sheep and goat keeping. It was also observed that 33.7% of households were involved in poultry enterprise and 25.3% involved in fish farming. Only 4.8% engaged in sheep and goat farming. Results obtained also revealed that 48.3% of the identified sheep and goat farmers kept breeds of sheep and goat from northern Nigeria while 40.4% maintained the west African dwarf breed. 34% of respondents believed that access to grants and credit facilities, 25 % believed provision of land in urban areas, while 21% believed improvement in small ruminant feed technology, would improve production. Lambing and kidding was mostly twice a year (48.3%). Breeding was mostly observed to be uncontrolled (51.7%). Also, the results showed that, 59.6% of the farmers were willing to pay for veterinary services. The most important diseases within these areas were worms, ecto-parasites and peste des petits ruminants (PPR). It can be inferred from the study that farmers within the region appear to pay greater emphasis on poultry production and fish farming to the detriment of smallholder sheep and goat farming which could be attributed to poor knowledge of sheep and goat farming technologies resulting to low productivity.

Improving livelihoods of smallholder farmers through region specific strategies: a case study of South African sheep production

ABSTRACTThe paper investigates if two groups of smallholder sheep farmers who farm using communal grazing land in the N8 development corridor of South Africa can be treated in a homogenous manner. Heterogeneous production environments should result in different production responses, which are unique to the production region. A better understanding of these unique responses could guide the development of improved strategies to increase smallholder livestock production in South Africa. A stochastic production frontier approach was used to evaluate two production districts before grouping the data and estimating the metafrontier. The metafrontier represents a homogenous benchmark for all producers. Results indicate that the two districts cannot be treated the same. Therefore a single production function and strategy cannot be used to improve productivity and efficiency of livestock production in both the districts. The conclusion is that the development of strategies to increase smallholder sheep producers, productivity and efficiency requires an understanding of the production, environmental and institutional factors that the farmers experience within that particular district. Considering the study areas used in the paper, attention to the more technical aspects of production and management can improve the farmers' productivity and efficiency.

Factors influencing off-take rates of smallholder sheep farming systems in the Western Cape Provinve of South Africa

The purpose of this study was to determine off-take rates in smallholder sheep farming systems in the Western Cape province of South Africa. A purposeful sampling technique was used where smallholder farmers were selected based on certain criteria. The criterion set out was that farmers must own between five and 100 sheep. Interviews were conducted with 72 smallholder farmers in three districts, namely the West Coast, Karoo and Eden. General information on the socio-economic status of the farmers was obtained through semi-structured questionnaires. The main sources of income for the Karoo farmers was livestock (46%) and crops for Eden (32%). Farmers in the West Coast area mostly relied on salaries (43%), thus off-farm income. The Karoo district sold a higher average number of lambs per year (41 ± 8.8), with West Coast and Eden selling the same average number of lambs per year at 7 ± 2.2 and 7 ± 2.6 respectively. Overall, the income derived from livestock is low and not economically sustainable. Therefore, different strategies (such as access to market, financial assistance, improved animal nutrition and health management, as well as sound breeding plans) should be employed to assist smallholder livestock farmers to increase off-take rates.

Using longitudinal syndromic surveillance to describe small ruminant health in village production systems in Myanmar

A novel syndromic surveillance approach was used to describe small ruminant health in Myanmar, to help overcome limitations in disease diagnosis common in many parts of the world, especially in low and middle income countries (LMICs). Observations were made from July 2015 to June 2016 of ten clinical syndromes in 12 goat herds and sheep flocks owned by smallholders in the Central Dry Zone. Strengths and weaknesses to using syndromic surveillance in a village setting were identified using a formal surveillance evaluation framework, ‘SERVAL’. Larger reporting teams made disproportionately more reports than smaller ones (86% compared to 14% of all reports, with a reporting rate ratio of 4.3 95% CI 3.5–5.4), which may have affected surveillance sensitivity. The benefits of the syndromic surveillance included its relatively low cost and ability to produce quantitative disease estimates that could be used to prioritise further disease investigation and extension activities. In particular, significant mortality was observed, with monthly mortality of 3.0% (95% CI 2.5–3.7%) and 0.28% (0.15–0.53%) in young and adult animals, respectively, and a population attributable fraction of mortality for young animals of 82% (68–91%). Mortality was associated with ill-thrift in young animals but had not previously been considered an important production-limiting condition in Myanmar. This information contributes to an understanding of the prevalence of excessive mortality in smallholder goat and sheep production systems. It is a practical example of the use of syndromic surveillance in a LMIC livestock production system, the results of which can direct future disease research, treatment and prevention to improve the health and productivity of small ruminants in Myanmar.

Flock composition, breeding strategies and farmers\u2019 traits of interest evaluation of Wollo highland sheep and their F1 crosses

BackgroundSheep production is a major component of the livestock sector in Ethiopia. The country owing to the large population of 30.70 million estimated numbers of sheep in the country and out of which about 72.14% are females, and 27.86% are males with diverse genetic resources. The real value of indigenous breeds was often under-estimated mostly due to their poor appearance and relatively low productivity. Developing countries in most cases opt for exotic breeds to increase animal productivity through crossbreeding or breed substitution without properly investigating the production potential of the indigenous breeds. The main objective of the research was to identify sheep flock composition and structure, farmers’ traits of interest and breeding objective of Wollo highland sheep, and their F1 crossbreed progenies.ResultsSmallholder farmers’ flock synthesized from breeding ewes, breeding rams, pre-weaned ewe lambs, pre-weaned ram lambs, unproductive ewes, castrated and fattened rams, with the percentage coverage of 29.2, 13.3, 15.5, 16.5, 12.4, and 12.5%, respectively. The maximum number of flock size was 289.0 sheep per flock and higher in the third stratum. The off-take rate percentage of the three strata presented as 21.9% in 1st stratum, 12% in the 2nd stratum, and 16.4% in the 3rd stratum and higher off-take rate recorded in the first stratum. Sheep producer’s traits of interest ranked by growth rate (first), body size (second) and marketing value was third rank. Communal breeding (random mating), village based controlled breeding, mixed type and private ram controlled breeding practice were comprised of 39.7, 61.7, 52 and 71.3%, respectively. The percentages of ewes per flock composition were presented as 36.5, 27.1 and 25.5%, respectively in the 3rd stratum, 2nd stratum and 3rd stratum in the order of their importance’s.ConclusionGenetic improvement practices at smallholder sheep producers situation was showing promising outcome with indigenous Washera F1 crossbred lambs and which designated for weaning rate, body size, marketing age, age at first lambing, good temperament and large litter size in the order of their rank. The contemporary breeding practice tendency indicated that, reduced flock size to improve flock productivity via crossbreeding practices.
