Lactic4Safe : role of bacterial microbiota in the environment, raw milk, and artisanal uncooked pressed cheese, as well as the impact of farming, milking, and cheese-making practices on the colonization of cheese by zoonotic bacterial pathogens
No full textA retrospective case control study conducted in France between 2022 and 2023, involving 20 farms (10 case and 10 control farms), investigated the factors influencing the sanitary quality of raw milk cheeses, focusing on the agricultural aspect and the bacterial microbiota characterised using 16S rRNA short reads metabarcoding from cheese production and the environment during manufacturing. The microbiological quality of raw milk cheeses is defined in Europe by Regulation (EC) No. 2073/2005. In this study, a set of food safety criteria related to the presence of food-borne pathogens such as Salmonella, Listeria monocytogenes and virulence factors of STEC in cheese for a long-time period (2017- 2022) prior to sampling was used to select the case farms. Using multivariate analysis, this study identified multiple bacterial species and critical sampling points such as raw milk, milking machines and wooden shelves that contribute to food-borne contamination of cheeses and highlights the importance of farm management practices such as additional vaccination or transhumance, hygiene and manufacturing practices to ensure the safety of raw milk cheeses. The bacterial species from raw milk cheeses or contact materials along the production chain contributing to the case or control farms were diversified in winter and summer. This study confirms the value of multi-block analysis for managing complex datasets and suggests that 16S rRNA markers from metabarcoding can help to identify critical control points and risk factors
Dataset of physical parameters of plantain genotypes grown in Côte d'Ivoire
No full textAloco or fried plantain is a local product in Côte d'Ivoire that is highly prized by the local population. However, its production is generally based on traditional banana varieties, which present many constraints with the advent of climate change. The creation of new plantain varieties more resistant to climatic hazards and with high production yields represents a relief for all populations. This report describes the physical characteristics of the plantain genotypes used in the preparation of aloco. A total of 58 plantain bunches divided into 11 genotypes (Saci, French sombre, French clair, Orishele, SH3640, Fhia 21, Zakoi, Big ebanga, Corne bout rond, Pita3, corne1) were used. Finger mass, finger circumference, finger length, pulp mass and skin mass were analyzed. The results of the analyses revealed that the Zakoi genotype recorded the lowest parameter values. In general, the finger lengths of the plantain genotypes ranged from 17 to 2'.13 Cm, and their circumferences from 10.25 to 13.25 cm. Finger mass ranged from 80g to 163.95g, with pulp mass ranging from 41g to 93.89g and skin mass from 38g to 71.45g
Comparaison des caractéristiques des charbons de bois issus de trois méthodes de carbonisation à Madagascar
No full textÀ Madagascar, 28,5 % des ménages utilisent le charbon de bois pour cuisiner. Pour répondre à la demande, des méthodes locales de carbonisation traditionnelles et peu efficaces sont utilisées. Cette étude examine trois méthodes utilisant des matériaux forestiers locaux : i) MATI (Meule améliorée à Tirage Inversé), actuellement en phase d'extension, ii) une meule hybride (MH) utilisée localement par les charbonniers, et iii) la pratique traditionnelle « Doro Dedaka » (DD). Ces techniques diffèrent par la position des évents, l’humidité et l'agencement du bois à carboniser dans la meule. L’objectif est de comparer les caractéristiques physico-chimiques et énergétiques du charbon d'Eucalyptus robusta obtenu par ces méthodes. Le rendement brut de MATI est de 25 %, contre 19 % pour MH et 12 % pour DD. Les densités apparentes des charbons des trois types de meules sont statistiquement similaires. Un charbon d’Eucalyptus acheté sur le marché (charbon x) a également été caractérisé. Les matières volatiles sont statistiquement similaires pour MATI, MH et DD tandis que celles du charbon x sont plus faibles (12,19%). De plus, la teneur en cendres varie significativement entre les différents types de charbons : le charbon HB possède la teneur en cendres la plus faible (2,04%), tandis que le charbon x présente la teneur la plus élevée (3,59%). La teneur en carbone fixe des charbons fabriqués est quasi-similaire, mais celle du charbon x est légèrement inférieure (75,02%). En termes de valeur calorifique, le charbon MATI est la meilleure avec 31 307 J/g, contre 31 070 J/g pour MH et 29 453 J/g pour DD. Le charbon x a une valeur calorifique de 29 723 J/g. Ces résultats montrent que MATI, avec son rendement élevé et ses performances énergétiques optimales, constitue une alternative prometteuse pour améliorer l'efficacité de la production de charbon tout en préservant les ressources forestières
Co-developing strategies to reduce antibiotic use in chicken production in Vietnam. Workshop outputs.
No full textTechnical, regulatory, or awareness strategies can be implemented to reduce the usage of antibiotics in livestock production to fight against antimicrobial resistance. However, they can be ineffective due to the misalignment with farmers’ realities. This study aimed to co-develop with relevant stakeholders’ strategies to reduce the usage of antibiotics in chicken production in Vietnam, a country with high use of antibiotics, using the ImpresS ex-ante approach. Three workshops were organized a week apart with chicken farmers, drug sellers’ representatives, public and private veterinarians, a chicken retailer, and academic staff operating at the communal, district, or provincial level. Participants have co-developed the vision that they would like to reach in 10 years to reduce the usage of antibiotics, problems to achieve this vision, changes that must be done to overcome these problems and finally they have designed two strategies to address these changes.
This dataset includes the raw results and the observers' reports for the three workshops.
- Common vision: Result of Workshop 1. "Yellow card" on which participants wrote on a yellow sheet of paper the vision to be achieved in ten years to reduce the use of antibiotics in chicken production in the province, that was then grouped by themes and compiled to develop the common vision.
- Problem Tree: Result of Workshop 1. The participants build problem trees by writing problems on a red card that prevents the realization of the common vision.
- Report 1: Result Workshop 1. Report of the observers.

Body Condition Scoring Grid for Donkey (Sahel and Savannah areas)
No full textIn tropical countries, and especially in Sub-Saharan Africa (Sahel and Savannah areas), 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 reared in grazing systems 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 two 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.
A BCS grid for sub-Saharan African donkeys comprising four levels of scoring was developed by Vall & al. (2001 and 2002). In 2001, Pearson and Ouassat published a BCS grid for working donkeys comprising nine levels of scoring based on observations carried out mainly in Morocco and also in Scotland.
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 donkey living in Sahel and Savannah areas. We propose a BCS grid with six levels admitting the hypothesis that in the donkey populations extreme animals could be present, being very thin (nutritional state worsened by parasitism), or very fatty
Spatio-temporal description of technical operations applied by farmers during the first years of the immature period, in intercropping and mono-cropping rubber systems from 2018 to 2022 in Buriram, Rayong and Trang, Thailand.
No full textAll the technical operations (TO) are described from the logging of the previous rubber plantation to the day of the interview. TO are described on a monthly scale, distinguishing mainly between the rubber row and the inter-row, and specifying the target crops. For the three provinces studied (Buriram, Rayong and Trang), two types of inter-row management were selected: mon-cropping and intercropping, with the intercrop most widely adopted in each province. (i.e. cassava in Buriram, pineapple in Rayong and upland rice in Trang)
