Body Condition Scoring Grid for Zebu cattle (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 calving. Overly lean females show a delay in the return of heat after calving, 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.
In Sub-Saharan Africa, many studies have been carried out for developing a BCS grid for cattle and especially devoted to Zébu (Bos Indicus): Pullan (1978) for the White Fulani zebu of Nigeria; Nicholson & Butterworth (1989) for zebu (Bos indicus) in general; Cisse (1995) for the Gobra zebu; Vall et al. (2002) for White and Red Fulani draft zebus in Northern Cameroon; Vall & Bayala (2004) for Sudanese zebus). For the BCS grid presented into this document, we relied mainly on systems based on six level of BCS that is the most frequent (Pullan, 1978; Cisse, 1995; Vall & al., 2002; Vall & Bayala, 2004).
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 Zebu cattle from Sahel and Savannah areas

Instrumental textural and colour data, for boiled potato, at CIP, Uganda
No full textThe study used potato tubers of 73 genotypes harvested from trials in Kenya. Colour (lightness, L, redness, a, yellowness, b, chroma, C and hue, h) was measured from images of peeled raw and cooked cross-sections of potato tubers captured by the DigiEye. Texture was analysed following penetration procedure conducted on cooked potato pieces of standard size
Instrumental textural data by penetrometry, QDA and consumer testing data for boiled potato, at CIP, Uganda.
No full textThis dataset contains instrumental textural data by penetrometry, Quantitative descriptive analysis data generated using sensory trained panels and consumer testing data for boiled potato. The activities, which led to the production of this dataset, were conducted at CIP, Uganda and were assessed and approved by the CIRAD Ethics Committee (H2020 ethics self-assessment procedure). When relevant, samples were prepared according to good hygiene and manufacturing practices. When external participants were involved in an activity, they were priorly informed about the objective of the activity and explained that their participation was entirely voluntary, that they could stop the interview at any point and that their responses would be anonymous and securely stored by the research team for research purposes

No full textInstrumental Textural data by TPA, Instrumental colour data, and QDA data was collected from three cooking banana (Matooke) varieties of contrasting characteristics (Kibuzi, M9 and Narita 24) harvested at maturity based on the fullness of the fingers. Six cooking methods were used to prepare the matooke. These are; conventional steaming method, boiling, steaming source pans, electric steaming, pressure cooking electric, pressure-cooking ga
Resistance to Melanaphis sacchari in the sugarcane cutivar R 365 as assessed using electrical penetration graph technique
No full textThis study focuses on the resistance of sugarcane, Saccharum sp. (Poaceae), to the sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), which vectors Sugarcane yellow leaf virus (SCYLV). Resistance was characterized in cultivar R 365, using the electrical penetration graph technique on aphids feeding on potted plantlets. We detected a delayed aphid salivation in phloem and inhibition of passive phloem sap uptake in R 365
