“…The industry presents a unique opportunity for trade and investments in certain aspects of a value chain. Markets also play different roles in livestock trade depending on the overall structure of the regional network [7]. Despite the importance of the sub-sector, growth in livestock output has been slow.…”

The study investigated the characterization and documentation status of available chicken breeds in Nigeria, likewise, the development of a chicken diversity database for inventory and future uses in Nigeria. Eleven major and some subsidiary chicken promoters/companies were surveyed. Data were obtained through individual interviews with some members of the day-old-chick (DOC) Merchants Association of Nigeria. A total of 400 respondents were randomly selected and interviewed on the chickens' companies' products and trading routes among customers. The data collected were subjected to descriptive statistical analysis of simple percentages and proportions. For the chicken database development, a free and opensource software XAMPP in Bitnami and content management framework (CMF) written in PHP and MySQL database were explored. None of the chicken promoters/companies in the country responded positively to the survey. Intra-West African countries trading was facilitated. The developed stand-alone chicken database named chickendb_ng runs on open-source software known as XAMPP (Cross-platform Apache MariaDB PHP and Perl) stack on the MariaDB Server 127.0.0.1 via TCP/IP with Server version of 10.4.1.8-MariaDB. The User, root @localhost with Protocol version of 10 and Server charset cp 1252 West European (Latin 1). The chicken database featured 23 tables in a friendly Graphical Users' Interphase to collect the data of interest on Nigerian chicken breeds/strains. Implementation of the developed stand-alone chickendn_ng will aid documentation of Nigerian chicken breeds, possible integration with other international databases, and may increase agricultural and food productivity in Nigeria. The chickens' database system may also lead to their outputs' growth and thereby strengthen intra-Africa trade.

“…These movements are seasonal and depend both on the availability of resources and on other sociocultural factors, and the mobility patterns and the distribution of the volume of animals involved change over the course of the year [3,4]. These movements integrate the region, connect contrasted agroecological areas, and, in addition, generate income for many supply chain actors, including producers, traders, transporters, and vendors, and contribute to the food and nutrition security of the region [5].…”

Livestock mobility, particularly that of small and large ruminants, is one of the main pillars of production and trade in West Africa: livestock is moved around in search of better grazing or sold in markets for domestic consumption and for festival-related activities. These movements cover several thousand kilometers and have the capability of connecting the whole West African region, thus facilitating the diffusion of many animal and zoonotic diseases. Several factors shape mobility patterns even in normal years and surveillance systems need to account for such changes. In this paper, we present an approach based on temporal network theory to identify possible sentinel locations, i.e., locations where pathogens circulation can be detected in the early phase of the epidemic (before the peak), using two indicators: vulnerability (i.e., the probability of being reached by the disease) and time of infection (i.e., the time of first arrival of the disease). Using these indicators in our structural analysis of the changing network enabled us to identify a set of nodes that could be used in an early warning system. As a case study, we simulated the introduction of transboundary animal diseases in Senegal and used data taken from 2020 Sanitary certificates (laissez-passer sanitaire (LPS)) issued by the Senegalese Veterinary Services to reconstruct the national mobility network. Our analysis showed that a static approach can significantly overestimate the speed and the extent of disease propagation, whereas temporal analysis revealed that the reachability and vulnerability of the different administrative departments (used as nodes of the mobility network) change over the course of the year. For this reason, several sets of sentinel nodes were identified in different periods of the year, underlining the role of temporality in shaping patterns of disease diffusion.

Animal movements are a major driver for the spread of Transboundary Animal Diseases (TADs). These movements link populations that would otherwise be isolated and hence create opportunities for susceptible and infected individuals to meet. We used social network analysis to describe the seasonal network structure of cattle movements in Uganda and unravel critical network features that identify districts or sub-regions for targeted risk-based surveillance and intervention. We constructed weighted, directed networks based on 2019 between-district cattle movements using official livestock mobility data; the purpose of the movement (‘slaughter’ vs. ‘live trade’) was used to subset the network and capture the risks more reliably. Our results show that cattle trade can result in local and long-distance disease spread in Uganda. Seasonal variability appears to impact the structure of the network, with high heterogeneity of node and edge activity identified throughout the seasons. These observations mean that the structure of the live trade network can be exploited to target influential district hubs within the cattle corridor and peripheral areas in the south and west, which would result in rapid network fragmentation, reducing the contact structure-related trade risks. Similar exploitable features were observed for the slaughter network, where cattle traffic serves mainly slaughter hubs close to urban centres along the cattle corridor. Critically, analyses that target the complex livestock supply value chain offer a unique framework for understanding and quantifying risks for TADs such as Foot-and-Mouth disease in a land-locked country like Uganda. These findings can be used to inform the development of risk-based surveillance strategies and decision making on resource allocation. For instance, vaccine deployment, biosecurity enforcement and capacity building for stakeholders at the local community and across animal health services with the potential to limit the socio-economic impact of outbreaks, or indeed reduce their frequency.
