WASTE AGRICULTURE MATERIAL IN ANIMAL FEED TREND EVALUATION: A BIBLIOMETRIC ANALYSIS

Abstract

The worldwide demand for sustainable livestock production has generated heightened interest in employing agricultural waste materials as alternative feed sources with the objective of improving resource efficiency and reducing environmental impact. Notwithstanding increasing research, a thorough assessment of publication trends, principal themes, and significant contributors in this domain remains insufficiently examined. This study performs a bibliometric analysis entitled "Waste Agriculture Material in Animal Feed Trend Evaluation," utilising Scopus Analyser and VOSviewer software to analyse 1,287 documents published from 2004 to 2024 systematically. The analysis reveals a notable increase in research output, especially after 2018, propelled by increased global awareness of sustainable practices and the circular economy. Prominent themes identified in the keyword analysis encompass "agriculture," "circular economy," "sustainability," and "bioconversion," underscoring the emphasis on waste valorisation and nutrient recovery in animal feed. The co-authorship analysis indicates robust international collaborations, with significant contributions from the United States, China, India, and European nations, highlighting the global character of this research domain. Prominent authors such as Tomberlin, Oenema, and Godbout have significantly influenced the research trajectory on novel feed alternatives. The findings highlight the growing importance of incorporating waste management strategies into animal nutrition to tackle issues concerning food security, environmental sustainability, and livestock efficiency. The results provide significant insights for future research, highlighting the necessity for the ongoing investigation into advanced bioconversion technologies and sustainable feeding practices to enhance the utilisation of agricultural by-products in animal feed systems.
