El objetivo del estudio fue describir el sistema de crianza de la población de llamas de cooperativas comunales (CC) y criadores individuales (CI) de la región Pasco, Perú. Se aplicaron encuestas en campo a cuatro administradores de CC y 145 CI. El objetivo principal de la crianza para las CC y los CI fue la producción de carne. Las llamas tipo K’ara predominaron en CC y el tipo Intermedio en CI. El tamaño promedio de rebaño en CC fue de 200 y en CI de 48 llamas. El apareamiento en CC fue controlado y en CI generalmente sin control. La edad al primer servicio de machos y hembras en CC y CI fue de 34.5 y 23.5, y 26.3 y 23.1 meses, respectivamente, con una proporción macho: hembra de 1.13 en CC y de 1.18 en CI. La permanencia promedio de los machos y hembras en el rebaño fue de 2.54 y 8.0 en CC y de 4.14 y 9.6 años en CI, respectivamente. Los reemplazos machos y hembras procedieron del mismo rebaño en 70 y 75% en CC y en 83.6 y 98.3%, en CI, respectivamente. La venta de reproductores machos fue destinado principalmente a criadores vecinos en 80 y 65% en CC y CI, respectivamente. La práctica de selección de machos y hembras se hizo en 26.9 y 16.6% de los CI, respectivamente. La selección de machos y hembras fue a los 6.5 meses en CC y a 11.3 y 14.0 meses de edad para machos y hembras, respectivamente, en CI. El criterio principal para la selección fue el tamaño de la llama.

Cattle production in southwestern Burkina Faso is under pressure because of resource scarcity, changing climate, and cattle diseases. Well-adapted local breeds, such as Lobi taurine cattle, are increasingly replaced by more productive exotic breeds. Community-based breeding programs (CBBPs) could be a viable option for preserving the breed and improving its productivity. Presuming that CBBPs would succeed only if they align with producers’ beliefs and values, we relied on a combination of conceptual frameworks (theory of basic values, rural livelihood transitions) to explore the values and beliefs of cattle producers. Security was the respondents’ dominant value in their aim to mitigate threats to livelihood, and it was closely linked to achievement in terms of harvest and animal quantity. Livestock-oriented respondents particularly valued conformity with accepted social roles, while achievement and power were more pronounced among crop-oriented respondents. We conclude that CBBPs, to be successful, will need to reduce threats to participants’ livelihood and make benefits of participation immediately visible. We consider the emergence of trusted leadership from the community to be pivotal for creating momentum for novel arrangements in cattle keeping and feeding.

Creole breeds are an invaluable genetic reservoir due to their adaptation to the environments where they are exploited. In particular, Creole goats in Latin America and the Caribbean play a preponderant role in the development and economic growth of rural communities. They represent a strategic option for these communities to migrate from poverty to prosperity, taking advantage of the adaptability and rusticity of these goats, given that they survive, reproduce, and produce acceptable levels of meat and milk in adverse conditions and environments. For this reason, they are a key species for generating foods of high biological and nutritional value, in the face of changing environmental and climatic conditions. Therefore, public policies should consider local or Creole goats as a priority species in productive support programmes, as well as in research programmes seeking to improve productivity in a sustainable manner in all environments where they are raised.

Livestock keepers in southwestern Burkina Faso hold the local Lobi taurine breed, local Zebu cattle, and their crosses. Some communities in the region have begun to implement community-based cattle breeding programs (CBBPs), which involve animal tagging and recording and, potentially, also bull sharing. Based on the hypothesis that the participation of livestock keepers in CBBPs depends on their attitudes towards these programs, we used questionnaires to survey the attitudes of 125 farmers towards cattle breeding strategies and tools. Results were analyzed using principal component analysis. Farmers showed a highly positive attitude towards maintaining the features of their preferred cattle breed, but their attitudes varied substantially towards crossbreeding for breed improvement. Farmers generally agreed that performance was more important than animal appearance, and most of them were willing to cooperate with breeders’ associations but were skeptical about sharing their bulls with other farmers. The majority was reluctant to record performance data, which may be due to a capacity deficit and their confidence in being able to select the best animals based purely on phenotype. Our analysis suggests that breeders’ associations, as a key component of CBBPs, should lay down clear rules and obligations for their members from the outset. Timely consideration of farmers’ attitudes towards different breeding tools may improve their uptake and guarantee the sustainability of CBBPs.

En alpacas los fenotipos del color de vellón tienen diferentes terminologías que induce a una confusión dentro del color marrón y sus tonalidades, el que requiere de una mejor descripción y cuantificación. En consecuencia los objetivos del estudio fueron cuantificar el color de fibra e identificar los PNSs informativos del gen MC1R (receptor 1 de melanocortina) en alpacas marrones y negras. Un fenotipo vicuña (n=14) y cuatro fenotipos de alpacas (n=79), marrón claro, marrón oscuro, marrón-negro y negro fueron evaluados por colorimetría. El vellón de vicuña mostró mayor luminosidad (47.74) e intensidad de color (24.33) respecto a las alpacas marrones. Los valores obtenidos de CIE L*a*b* (luminosidad e intensidad) sugieren valores bajos en alpacas eumelánicas y altos en alpacas feomelánicas. En vicuña y alpaca la secuencia codificante del gen MC1R tiene un solo exón de 954 pb, las vicuñas no mostraron la deleción (c.224_227del). Sin embargo, esta deleción se ha observado en los tres fenotipos de alpaca (marrón claro, marrón oscuro y negro), al igual que los cinco PNSs no sinónimos que ya fueron descritos en otras poblaciones, c.82A>G, c.259G>A, c.376G>A, c.587T>C, c.901C>T (p.T28A, p.M87V, p.G126S, p.F196S y p.R301C). Para las dos especies, se identificaron un total de ocho haplotipos definidos por los cinco PNSs. No se observaron asociaciones entre los fenotipos de color y los PNSs: c.259G>A, c.376G>A y c.901C>T (p>0.05), probablemente debido a la influencia de otros genes como el ASIP en la expresión del color. Nuestros resultados, así como los estudios previos evidenciaron regiones altamente conservadas en la secuencia codificante del gen MC1R.

High‐throughput genomic markers provide an opportunity to assess important indicators of genetic diversity for populations managed in livestock breeding programs. While well‐structured breeding programs are common in developed countries, in developing country situations, especially in West Africa, on‐farm performance and pedigree recordings are rare, and thus, genomic markers provide insights to the levels of genetic diversity, inbreeding and introgression by other breeds. In this study, we analysed key population parameters such as population structure, admixture and levels of inbreeding in three neighbouring populations of African taurine and taurine × Zebu crosses managed by community‐based breeding programs in the South‐West of Burkina Faso. The three populations were pure Baoulé (called Lobi locally) in sedentary production systems, Baoulé x Zebu crossbreds in sedentary systems and Zebu × Baoulé crossbreds in transhumant production systems, respectively. The total sample analysed included 631 animals and 38,207 single nucleotide polymorphisms after quality control. Results of principal component and admixture analyses confirmed the genetic background of two distinct ancestral populations (taurine and zebuine) and levels of admixture in all three breeding populations, including the presumably pure Baoulé group of animals. Inbreeding levels were moderate, compared to European dairy and beef cattle populations and higher than those of Brazilian Nellore cattle. Very few animals with inbreeding levels indicating parent–offspring or full sib mating were observed, and inbreeding levels indicating half sib mating were also rare. For the management of breeding populations, farmers were advised to exchange best young bulls. The crossbreeding levels of presumably pure Baoulé animals are of concern to the breeding program due to the high level of endangerment of pure African taurine cattle populations across West Africa. Future rounds of bull selection in the community‐based breeding program will make use of genomic information about admixture levels.

Cattle are one of the most important livestock species in West Africa, providing multiple services to farmers and contributing to national economies. Various breeding strategies have been implemented to enhance their productivity and have improved farmer livelihoods. This review describes cattle breeding experiences across West Africa, spanning the N’Dama breed in Mali, Senegal, and The Gambia to the breeds Azawak Zebu, Fulani Zebu, and taurine Baoulé in Burkina Faso. The main objectives of most breeding programs have been to optimize meat and milk performance of taurine and Zebu cattle as well as trypanotolerance of taurine cattle. In some cases, “closed nucleus” schemes have proven limited and so have evolved into “open nucleus” schemes. Recent community-based breeding programs have shown promise. The major challenges of breeding programs remain defining realistic breeding objectives and securing the involvement of stakeholders. All the strategies reviewed here have been funded externally within development or research projects that are often too short to yield tangible genetic improvement, and whether they will continue beyond those projects is uncertain. This review highlights the need for continuing government support to ensure the sustainability of local cattle breeding programs.

Maintaining the diversity of small ruminant genetic resources is instrumental for sustainable agricultural production. Community-based livestock breeding programs (CBBPs) have emerged as a potential approach to implement breeding programs in smallholder farms. This study assesses the viability of CBBPs as a potential approach for conservation and improvement of indigenous small ruminants, using case studies of goat CBBPs in Malawi and Uganda. Data were collected using focus group discussions, personal interviews, and direct observations. The program promotes and empowers smallholders to have access to small ruminant feed resources through the protection of existing communal pasturelands, capacity building in pasture production, and conservation of crop residues and crop by-products. Implementation of the CBBP enhances the contributions through improved animal growth performance, kids’ survival, and twinning rates leading to increased offtake rates and better prices. The existence of permanently established supporting organizations and other stakeholders provides sustainable institutional support instrumental for the establishment and growth of CBBPs. However, the establishment of functional community-based institutions (producer cooperatives) and investments in institutional/policy reforms to safeguard fair trading, access to common resources by small ruminant keepers, and adoption of the CBBP model into national livestock development programs are some of the key milestones that can guarantee sustainability.

This study aimed to estimate genetic parameters for four guinea pig lines of a crossbreeding scheme. Two paternal lines are selected for growth rate (P1) and feed conversion rate (P2), whereas two maternal lines are selected for growth rate of litter (M1) and litter size at birth (M2). The heritabilities and genetic correlations were estimated with animal linear models employing multivariate analyses with REML. The heritabilities for birth weight (BW) were 0.21±0.02 and 0.23±0.03 for P1 and P2, respectively, and for weaning weight (WW), the heritability was 0.28±0.03 for P2. The estimates for weight at 60 days of age (W60) were 0.34±0.01 and 0.47±0.04 for P1 and P2, respectively, and for partial feed conversion rate was 0.46±0.03 for P2. Heritabilities for litter weight at birth (LW) were 0.09±0.03 and 0.10±0.03 for P1 and M1, respectively. For litter weight at 10 days of age (LW10), the heritability was 0.15±0.03 for M1. Heritabilities for litter size (LS) were 0.17±0.03, 0.20±0.03 and 0.11±0.03, and for number of pups born alive (BA) were 0.09±0.03, 0.14±0.03 and 0.09±0.03 for P1, M1 and M2, respectively. Similarly, high genetic correlations were found between BW, WW and W60 and between LW, LS, LW10 and BA. The genetic correlation between BW direct and maternal was moderately negative (− 0.24 ± 0.10) for P1. These results show the genetic status for all four guinea pig lines, which is essential for the further improvement of the currently implemented breeding programme and also indicate an opportunity for genetic improvement.

A study was conducted to determine tangible and intangible benefits of local goats to smallholders in low input crop-livestock production system where community-based goat breeding program (goat CBBP) is being implemented. Data was collected through a 12-month flock and household (137 households) monitoring study between August 2017 to July 2018. Data collected was analyzed using enterprise budgeting and cost-return analysis. The results showed that local goat enterprises in smallholder farms are profitable and economically viable. The mean annual net profit per flock and per goat was MK54,406 and MK11, 140 (€1 = MK830.00), respectively. The average return on capital invested was 24.6%, exceeding the prevailing average commercial deposit rate (8%) by several folds. Goats accounted for 61.2% of the total livestock household income representing the biggest contributor, while cattle, pigs and chickens contributed 17.6%, 15.5% and 4.1%, respectively. Sale of live goats constituted the major (79.2%) proportion of the total offtake rate, suggesting that goats are primarily kept for generation of cash revenues. Inclusion of intangible benefits of goats significantly increased the mean annual net profit and the return on capital by 60.3%, reflecting the importance of socio-economic roles goats play in providing current and future economic stability to rural households’ economy. Hence, programs like goat CBBPs are meant to harness the potentials of local goats to optimize their contributions towards reduction of rural poverty and hunger. Therefore, financing and supporting scaling up of such programs is a meaningful direct investment into the development of rural economy.

Cattle production is an essential livelihood strategy in south-western Burkina Faso. Although having a distinct cultural role and known to be resistant against African animal trypanosomosis, the Lobi taurine cattle breed is endangered due to its low market value. As the first step in preservation efforts, our study aimed to develop a typology of production systems at the farm level. We used a structured questionnaire and focus group discussions for collecting data on household characteristics, socioeconomic activities, livestock, and access to services. The sample comprised 169 households in three communities. The analytical strategy included factor analysis of mixed data and hierarchical clustering. We identified four distinct types of cattle production systems: (1) sedentary Lobi farms, (2) sedentary crossbreed farms, (3) semi-transhumant Fulani zebu farms, and (4) transhumant Fulani zebu farms. Significant factors in developing this typology were the farmers’ ethnic group, crop diversity, cattle herd size, cattle herd composition, number of small ruminants, and livestock management strategies. Across all production systems, men were considered being primary decision-makers in cattle production, with women, herders, and children being responsible for specific tasks. All identified production systems are increasingly confronting disease pressure and scarcity of water and land. Future efforts in preservation and breeding will need to respond to these trends in the agroecosystem, integrate risk management measures, and resonate with the specific needs of the different household members involved in cattle rearing.

Context The productivity of Ethiopian smallholder farms is considered to be low owing to different factors such as feed shortage, lack of breeding strategies, disease prevalence and missing marketing strategies. Aim The main objective of the study was to develop a dynamic, stochastic herd model by adopting system dynamic modelling methodology for evaluation of the effect of increased feed availability (forage production) in combination with different fattening strategies on herd dynamics and profitability of an Ethiopian sheep population. Methods Forage production utilising part of smallholder farmers’ cropland was built into a dynamic simulation model. Two alternative feed-supply systems were evaluated: turning 25% and 50% of the current cropland into area used for forage production. The simulation period was 20 years, the first 10 years representing the baseline fattening scenario (culled rams fattened). For the last 10 years, genetic selection was introduced and two scenarios were evaluated: fattening of culled rams (Scenario I) and fattening of young rams (Scenario II). Key results Increasing the feed supply resulted in an increase to the herd size when the model balanced dry matter supply and demand of the herd. Fattening of young rams (Scenario II) with genetic selection was significantly more profitable than the baseline and Scenario I in both of the simulated alternative feed-supply systems. This can be used for regular cash generation, which might reduce disposal of animals at lower price in cases of need for emergency cash. Conclusions Overall, the simulation model demonstrates that production of improved forage crops should be combined with selective breeding and an appropriate finishing strategy. The competition for resources (land and labour) with crop production, forage seed shortage and extended family size are other challenges raised by smallholder farmers for the feasibility of the two alternative feed-supply systems.

Genetic characterization of African goats is one of the current priorities in the improvement of goats in the continent. This study contributes to the characterization effort by determining the levels and number of generations to common ancestors (“age”) associated with inbreeding in African goat breeds and identifies regions that contain copy number variation mistyped as being homozygous. Illumina 50k single nucleotide polymorphism genotype data for 608 goats from 31 breeds were used to compute the level and age of inbreeding at both local (marker) and global levels (FG) using a model-based approach based on a hidden Markov model. Runs of homozygosity (ROH) segments detected using the Viterbi algorithm led to ROH-based inbreeding coefficients for all ROH (FROH) and for ROH longer than 2 Mb (FROH > 2Mb). Some of the genomic regions identified as having ROH are likely to be hemizygous regions (copy number deletions) mistyped as homozygous regions. Although the proportion of these miscalled ROH is small and does not substantially affect estimates of levels of inbreeding for individual animals, the inbreeding metrics were adjusted by removing these regions from the ROH. All the inbreeding metrics varied widely across breeds, with overall means of 0.0408, 0.0370, and 0.0691 and medians of 0.0125, 0.0098, and 0.0366 for FROH, FROH > 2Mb, and FG, respectively. Several breeds (including Menabe and Sofia from Madagascar) had high proportions of recent inbreeding, while Small East African, Ethiopian, and most of the West African breeds (including West African Dwarf) had more ancient inbreeding.

Gastrointestinal nematodes (GIN) remain one of the main health and production constraints of sheep globally. Considering alternatives to anthelmintics in control of GIN of sheep has become important mainly due to development of anthelmintic resistance. In this study, we used a questionnaire survey in combination with participatory epidemiology methods, ranking and scoring, with the objectives of (1) understanding local sheep disease problems related to GIN in community-based breeding programs (CBBP) in Bonga and Horro of Ethiopia, compared to neighboring communities not involved in CBBP, and (2) assessing current practices and preferences in control of GIN of sheep in both types of communities. The most important disease conditions of sheep in Bonga CBBP with weighed ranks of 1 to 3 were coenurosis, diarrhea and coughing. The corresponding sheep disease conditions in Horro CBBP were coughing, diarrhea and bottle jaw. Diarrhea and bottle jaw presumably are related to gastrointestinal nematodes. Ethnoveterinary medicinal plants are widely used in Bonga while the knowledge is at risk of loss in Horro. Respondents in non CBBP and CBBP communities did not differ (p > 0.05) regarding most of the plant species used frequently in control of GIN in Bonga. There was significant difference (p < 0.001) in frequency of anthelmintic use between CBBP and non CBBP communities for each of the two locations, Bonga and Horro. In Horro, CBBP farmers considered anthelmintics as more sustainable GIN control option than non CBBP farmers (p < 0.001). This can be attributed to lack of awareness pertinent to development of anthelmintic resistance. In conclusion, local knowledge, practices and preferences of farmers should be considered when designing and implementing control programs for gastrointestinal nematodes.

Runs of homozygosity (ROH) islands are stretches of homozygous sequence in the genome of a large proportion of individuals in a population. Algorithms for the detection of ROH depend on the similarity of haplotypes. Coverage gaps and copy number variants (CNV) may result in incorrect identification of such similarity, leading to the detection of ROH islands where none exists. Misidentified hemizygous regions will also appear as homozygous based on sequence variation alone. Our aim was to identify ROH islands influenced by marker coverage gaps or CNV, using Illumina BovineHD BeadChip (777 K) single nucleotide polymorphism (SNP) data for Austrian Brown Swiss, Tyrol Grey and Pinzgauer cattle. ROH were detected using clustering, and ROH islands were determined from population inbreeding levels for each marker. CNV were detected using a multivariate copy number analysis method and a hidden Markov model. SNP coverage gaps were defined as genomic regions with intermarker distances on average longer than 9.24 kb. ROH islands that overlapped CNV regions (CNVR) or SNP coverage gaps were considered as potential artefacts. Permutation tests were used to determine if overlaps between CNVR with copy losses and ROH islands were due to chance. Diversity of the haplotypes in the ROH islands was assessed by haplotype analyses. In Brown Swiss, Tyrol Grey and Pinzgauer, we identified 13, 22, and 24 ROH islands covering 26.6, 389.0 and 35.8 Mb, respectively, and we detected 30, 50 and 71 CNVR derived from CNV by using both algorithms, respectively. Overlaps between ROH islands, CNVR or coverage gaps occurred for 7, 14 and 16 ROH islands, respectively. About 37, 44 and 52% of the ROH islands coverage in Brown Swiss, Tyrol Grey and Pinzgauer, respectively, were affected by copy loss. Intersections between ROH islands and CNVR were small, but significantly larger compared to ROH islands at random locations across the genome, implying an association between ROH islands and CNVR. Haplotype diversity for reliable ROH islands was lower than for ROH islands that intersected with copy loss CNVR. Our findings show that a significant proportion of the ROH islands in the bovine genome are artefacts due to CNV or SNP coverage gaps.

Understanding the relationship between genetic admixture and performances is crucial for the success of crossbreeding programs. Use of small sets of ancestry informative markers (AIMs) is a cost effective option to estimate the levels of admixture in situations where pedigree recording is difficult. In this study we select AIMs from Ovine 50KSNP data (SNP – single nucleotide polymorphism) and validate their ability in estimating the contributions of parental breeds to get information about optimum admixture levels for smallholders. We estimated admixture levels using ADMIXTURE software based on 74 AIMs selected from Ovine 50KSNP data. Awassi x Ethiopian fat-tailed crossbred sheep populations kept in government farms and farmer villages in different districts were included in the study. Mean Awassi levels estimated based on the selected AIMs were close to the Awassi levels obtained from pedigree information. Estimates from the 74 SNPs were compared to subsets of 65, 55, 45, 35, 25 and 15 SNPs selected based on both top and bottom fixation index (FST) rank using Spearman’s rank correlation (r = 0.862–0.996). A t-test comparison revealed that all SNP subsets had produced similar (P > 0.05) estimates with the 74 SNPs, except for the bottom 15 SNPs (P < 0.05). However estimates based on 45 and above SNP subsets were relatively close to the fitted regression line (r = 0.969–0.996). Association of admixture levels with lamb growth showed that Awassi level affected (P < 0.05) eight months weight in both farmer locations, lambs with higher Awassi levels were heavier. Lambing interval of ewes was longer as Awassi level increased, but this drawback was outweighed by the increased productivity of ewes in terms of eight months lamb weight per year. The results indicate that the Ovine 50KSNP array is a powerful tool to identify small sets of AIMs for admixture studies. The results of this study reveal about 45AIMs to accurately estimate admixture levels. If admixture estimation service with such low cost SNP chip would be available, farmers would have a clear market advantage without the need to rely on incomplete or possibly inaccurate pedigree records. Based on the results presented here, we were able to suggest optimum levels of breed composition for the two farmer environments investigated.

The sustainability of activities related to animal genetic resources (AnGR) management depends largely on the participation of a range of stakeholders, both public and private. In this study, we investigated factors explaining differences in stakeholder involvement in AnGR management across countries, based on an historical perspective and an analysis of the 128 official country reports provided during preparation of The Second Report on the State of the World's Animal Genetic Resources for Food and Agriculture. Results of principal component analyses indicated that countries differed in the involvement of stakeholders in AnGR management, generally with greater involvement of livestock breeders and their organizations in developed countries. Developing countries tended to be divided into two groups, those with little involvement by stakeholders and those with high involvement by government/research organizations. Depending on the country, the involvement of government/research organizations versus breeders/livestock keepers organizations and commercial companies also differed, which could be linked to some extent to their historical background. The level of involvement of breeders 'associations or cooperatives was positively correlated (r=0.68) to the general extent of AnGR activities within the country. Our results underline the importance of involving breeders and livestock keepers in the development of management activities, while public support is required as well, especially in the early stages of capacity development. In developing countries, development policies relative to AnGR management should therefore seek to promote coordination among livestock keepers through creation and empowerment of cooperatives, associations or community-based approaches
