Baseline to measure the impact of FFS-LFP on food diversity in agricultural households in Uganda - 2025
No full textBaseline survey conducted to assess the impact of FFS-LFP on food diversity among farming households in Uganda, involving nearly 1,100 households. The survey was conducted in March 2025 in four districts in Uganda (Amuru, Iganga, Kalaki, and Serere). The survey provides a description of household composition, farming systems, and consumption patterns
Community Composition and Structure of Psyllophagous Ladybirds in a Tropical Environment
No full textThis study examines the community composition and structure of psyllophagous ladybirds (ladybird species that feed on psyllids) in a tropical environment, focusing on their interactions with psyllids as a primary food resource. The research investigates the effects of landscape composition, climatic conditions, and prey availability on the structure of all ladybird species associated with psyllids and specifically on the presence and abundance of species whose life cycles depend on psyllids.
Sampling was conducted on La Réunion Island, focusing on two plant species heavily infested with psyllids: Leucaena leucocephala and Acacia heterophylla. Ladybirds and psyllids were regularly collected over a two-year period using a thermal aspirator, complemented by visual inspection. Sampling took place at eleven sites visited on a monthly basis

Body Condition Scoring Grid for Goat (Sahel and Savannah areas)
No full textIn tropical countries subject to significant quantitative and qualitative variations in the availability of fodder during the year, the dissatisfaction of feed needs is a frequent situation for animals maintained on rangelands without a sufficient supplementation with feed concentrates.
The Body Condition Scoring (BCS) is a useful way to assess the state of body reserves (subcutaneous fat, muscle mass) which reflects the animal's production (growth, milk, work) and reproduction capacities. The evaluation of the body reserves of an animal through the scoring of their body condition is important to adjust their diet and appreciate their general state of health, as well as their reproductive and production capacity (meat, milk, work, etc.). Managing body reserves is one way of responding to variability in quality and access to feed resources. In females, reserves play an important buffer role during lactation. They can make up for insufficient intakes from the ration. Indeed, the level of production depends on the nutrients provided by the feeds, but also on the animal's body reserves when the feed-based supplies do not fully cover their needs, especially during the dry season. The BCS impacts the interval between births. Overly lean females show a delay in the return of heat after giving birth, the direct consequence of which is the increase in the parturition interval and consequently a decrease in herd productivity.
The assessment of these reserves through Body Condition Scoring (BCS) represents a management tool for livestock farmers, agricultural advisors and livestock development stakeholders. BCS is a simple, inexpensive and fast method. Several animals can be scored in one session. It allows to compare the BCS of individuals or herds: 1) raised in different production systems or environments, 2) or, during different seasons (dry season and rainy season). BCS can be used as a tool for monitoring and alerting the nutritional level of domestic animal populations. To do this, BCS alert thresholds and a BCS collection and monitoring system must be defined on reasoned samples of animal populations.
It is an easy-to-use field tool. However, a good mastery of the BCS grid as well as a regular practice of scoring are necessary to obtain precise and reproducible ratings. It can also be used as a tool for monitoring and alerting the nutritional level of animal populations. Thus, the farmer can be called at any time to intervene on the feed ration and / or the health of the animal.
Few studies have been carried out for developing a BCS grid, specially devoted and applicable to Sub-Saharan goats in Africa. Existing BCS systems for goats are based on a four-points BCS grid (Imadine, 1991), which has been adapted from systems previously developed for temperate goats (Morand-Fehr and Branca, 1987; Hervieu et al., 1991). Such a system includes examining the lumbar region (transverse and spinous apophyses, fat thickness, and skin appearance), the sternal region (fat thickness) and the general appearance of the animal (ribs, bones protrusions in the rump, transverse and spinous apophyses; Imadine, 1991; Cisse 1995; Cisse et al., 1992, 1994). The criteria retained by those authors includes observation from the rear and from the flank of the animal.
In 2020, Vall proposed a standardized BCS scoring system for tropical livestock animals for large animals (cattle, camels), small animals (sheep, and goats) and for donkeys, and horses. This document presents this BCS system applied to the Sahelian goat
Development of chimeric multivalent proteins for serological diagnosis of African animal trypanosomosis
No full textThe data presented relate to the article entitled: "Development of Chimeric Multivalent Proteins for Serological Diagnosis of African Animal Trypanosomosis."
This study developed chimeric proteins for the serological diagnosis of African Animal Trypanosomosis (AAT), composed of immunoreactive regions from multiple known antigens, using genetic engineering. After identifying candidate antigens, we selected specific ones using bioinformatics and designed five chimeric constructs in silico: three species-specific and two pan-trypanosome chimeras.
The 3D structures of the five chimeras were predicted using AlphaFold2 Colab. The coding sequences of these chimeras were synthesized, cloned into expression vectors, expressed, purified, and preliminarily evaluated using sera from infected and non-infected animals
Seed morphometrics of white and black fonio seeds: passport data and morphometrics data
No full textPlant genetic resources characterization is essential for their conservation and their use in both breeding strategies and adaptation to global change. In Western Africa, two small indigenous grain cereals are found, black and white fonio (Digitaria exilis and Digitaria iburua respectively). Fonio genetic resources are preserved in seed collections, yet seed characterization is not used to identify the two fonio species.
We analysed seeds of 98 accessions of white fonio and 20 accessions of black fonio.
We used a morphometric approach as a simple and reliable method to identify the two fonio species, which is crucial to improve the quality of associated passport data and to enhance the value of fonio collections.
We provide here the passport data and the morphometric data used to perform the analyses
NIRS calibration for yam mouldability at Cirad UMR Agap Institut, France
No full textThe quality of pounded yam is a key criterion for the adoption of new varieties by both producers and consumers. Its assessment appears to be multifactorial. To date, no single compositional trait—such as amylose content, pectins, or dry matter—can reliably predict this quality. These traits are, in many cases, necessary but not sufficient.
The objective of this study is therefore to predict the mouldability of yam varieties—i.e., their ability to form a cohesive dough rather than a purée—directly from near-infrared (NIR) spectra acquired on yam flour
Modelled and observed Aedes albopictus mosquito population dynamics during a SIT field trial, Mauritius, 2017-2019
No full textThe prevention of diseases caused by Aedes-borne pathogens, such as dengue, chikungunya and Zika viruses, relies on mosquito control. An innovative method adapted for Aedes albopictus mosquitoes is the Sterile Insect Technique (SIT) that consists in the mass-release of sterilized mosquito males. The impact of SIT and the optimization of release strategies can be studied from modelling.
This dataset includes entomological collected on the field during an SIT trial in Mauritius, 2017-2019, as well as modelled mosquito population dynamics, obtained from simulations using ARBOCARTO tool, for the same period.

Dataset for crumbliness of boiled yam through textural and dynamic rheology measurements in Benin
No full textCrumbly texture is a key attribute of boiled yam and it depends on yam variety. Previous studies revealed the link between boiled yam crumbliness and the hardness from penetration test (DOI 10.1002/jsfa.12589). Despite this strong relationship, the hardness expressed by the texturometer may not capture/reflect the crumbliness. In this respect, other new parameters were extracted from the texture profiles and subjected to further analyses. In addition, a dynamic rheology analysis was carried out in order to identify the relevant parameters capable of representing or correlating with the crumbliness of boiled yams
