Challenges for Animal Health and Production in the Tropics and Mediterranean for the next 55 years

Tropical Animal Health and Production is a journal founded 55 years ago. It is dedicated to the publication of results of original research, investigation, and observation in all fields of animal health, welfare and production which may lead to improved health and productivity of livestock and better utilization of animal resources in tropical, subtropical and similar environments. Research is in strong alignment with the United Nations' Sustainable Development Goals, particularly No Poverty, Zero Hunger, and Good Health and Well-being. To celebrate its 55th anniversary, the editorial board has composed this Editorial article in an effort to address the major challenges that animal and veterinary scientists in the tropics and adjacent regions will address over the next 55 years. The task is accomplished in a systematic fashion addressing the topic species by species (cattle, small ruminants, pigs, poultry, camelids, etc.) and in the context of different groups of health challenges encompassing production, vector-borne, parasitic and transboundary diseases. Challenges are difficult and complex, and the solutions herein proposed may be difficult to implement. It aims to be an informed overview of the major difficulties the sector will experience in the near future, ultimately suggesting tools to address them. Only time will tell if they are accurate, effective or implementable. Nevertheless, Tropical Animal Health and Production Editorial Board, secretariat, reviewers and authors will certainly do their best to contribute to the advancement of animal health and production in the Tropics and the Mediterranean.

Evaluation of the effect of Carica papaya seed on the growth performance of fattening rabbits

Successful breeding depends on feeding. The present study aims to evaluate the Carica papaya seed effect on the growth performance of rabbits. The zootechnical parameters studied are weight growth, average daily gain, Feed Conversion Ratio, and carcass characteristics of kits. The experiment was conducted on 48 rabbits, divided into 4 groups, for 6 weeks. Forty-eight rabbits were divided into four (04) groups of 3 repetitions of 4 rabbits. The animals were fed diets containing various levels of papaya seed powder at variable contents: 0% (group T0), 4% (group T1), 6% (group T2), and 8% (group T3). At the end of the experiment, three animals were slaughtered in each animal group to assess the quality of the carcasses and organs. 6% of the seeds of Carica papaya significantly improved (p < 0.05) the average daily gain of the kits: T2 (22.40 g / d) compared to the T0 group (11.32 g / d), T1 (12.20 g / d) and T3 (17.53 g / d). The best Feed Conversion Ratio (0.80) was recorded in the animals of group T2. In contrast, the highest carcass yield was recorded in the rabbits of group T3 (62.70%). In conclusion, 6% was optimal in the feed rations of fattened rabbits to improve production performance. Breeders can consider the benefits of introducing Carica papaya seeds into the rabbits' diet.

A scalable approach to improve CSA targeting practices among smallholder farmers

With climate change, population growth, and land degradation exerting mounting pressures on agricultural systems in developing countries, climate-smart agriculture (CSA) strategies have been prioritized as a means to strengthen smallholder farmers' resilience. However, precise targeting methodologies remain a challenge. This study employs a comprehensive approach, integrating Socio-economic, and Biophysical (SEBP), and the Five Capitals Model analyses encompassing human, social, physical, natural, and financial capital. The study employs factor analysis for mixed data (FAMD), cluster analysis using partitioning around the medoids (PAM) and univariate and bivariate techniques to identify and classify distinct typologies of smallholder farming systems in Senegal's Tambacounda and Sedhiou regions in 2020. A probit regression model gauges CSA adoption probability, to better focus CSA efforts. Results underscore the pivotal role of SEBP factors in shaping distinct farmer typologies, enabling precise CSA targeting. Geographical distribution patterns of these typologies reveal non-random clustering, particularly in specific regions. Four farmer typologies emerge: Cluster 1 (Sedhiou, low-income, high climate challenges), Cluster 2 (Sedhiou and Tambacounda, low-to middle-income, moderate climatic challenges), Cluster 3 (Tambacounda, high income, favorable climate), and Cluster 4 (Tambacounda, low income, severe climate challenges). Technology mismatches emerge between farmers' SEBP profiles and capital assets, prompting the identification of relevant technologies for soil fertility restoration and increased output. These findings highlight the importance of implementing CSAs in accordance with specific requirements, such as enhancing soil fertility, yield, and nutritional quality. A contextual understanding of local agricultural dynamics is likewise necessary for optimizing intervention strategies, according to the study.
