Insects, recognized for their exceptional nutritional profile, represent a promising alternative protein source for use in animal feed. As the global demand for animal-derived food products continues to rise, identifying innovative and sustainable protein solutions has become imperative. Despite their potential, the adoption of insect-based feed faces significant barriers, particularly regarding consumer acceptance and safety concerns. Many individuals are reluctant to embrace unfamiliar animal-origin products, and in Algeria, no research to date has investigated consumer attitudes toward insect-based feed alternatives. This study examines Algerian consumers' perceptions of the benefits and risks of insect-based feed (for poultry, cattle, small ruminants, and fish) and the factors influencing their acceptance. To achieve this, an online survey was conducted targeting Algerian consumers in 2024. Over 250 responses were collected and analyzed using descriptive statistics and logistic regression. Participants showed greater willingness to approve insect-based feed for poultry and fish, with 48% expressing acceptance for each, compared to only 23% approval for its use in bovines and ovines. The most influential factors affecting consumer acceptance were nutritional benefits (55%), disgust (53%), animal welfare (45%), and psychological factors (38%). The analysis of participants' responses revealed varying perceptions regarding the advantages and risks associated with using insects in animal feed. Among the advantages, the most agreed-upon aspects included improved organic waste valorization (44% to 20%), enhanced sustainability (44% to 24%), reduced production costs (46% to 29%), and increased global food availability (38% to 22%). Conversely, participants also highlighted concerns about potential risks, including allergenic reactions in humans (50% to 42%) and animals (50% to 39%), bio-diversity impacts (58% to 51%), microbiological contamination (51% to 45%), chemical residues (40% to 38%), and competition with other agricultural activities (35% to 29%). These concerns indicate a need for rigorous safety assessments, transparent communication about benefits and risks, and public education to address misconceptions.
