Special Issue Information

Dear Colleagues,

The expected growth of the global population is one of the greatest challenges mankind has to face in the future. This growth is also expected to be paralleled by a steady increase in the demand for high-quality and nutritive animal food products. It is thus pivotal for livestock systems to rely on alternative animal protein sources to remain sustainable in the medium–long term. In this context, animal protein sources such as insects and fish by-products are promising alternatives to conventional ones, especially in circular economy systems which are driven and evaluated by life cycle thinking. New feeding strategies can be applied to transform food waste biomasses and streams, such as insects and fish by-products, into valuable feed materials. This Special Issue aims to gather valuable scientific contributions on this topic, which, being multifaceted by nature, requires a comprehensive view to tackle, as it concerns, for example, dedicated producing systems, animal nutrition, health and welfare issues, circularity, and the social economic and environmental sustainability of feed production based on insects and/or fish by-products, as well as other novel and emerging issues. The submission of ground-breaking research in the form of regular papers, short communications, and systematic reviews is thus invited for this Special Issue.

The Tenebrio molitor larva (yellow mealworm) holds great potential as a sustainable ingredient in food and feed. Optimizing its growth under mass farming requires careful water management. However, the availability and cost of fresh fruit and vegetables, which are the most widely used sources of water, can vary geographically, which calls for the search for relatively affordable, effective, and readily available alternatives. We evaluated the effect of three water sources (bean sprouts, lettuce leaves, and milk) as well as their quantity on weights and nutrient profiles of reared T. molitor larvae. Newly hatched mealworm larvae were maintained in controlled conditions of 25 °C and 60% relative humidity under a 12-h light–dark cycle for 15 weeks. When provided as sole-supplements, bean sprouts induced the highest larval weight gains compared to fresh lettuce leaves, which in turn performed better than milk and water. However, the addition of milk to the vegetable supplements enhanced growth. Furthermore, doubling the level of water supply resulted in 70% higher larval weights by week 14 post hatching. Moreover, water sources did not change the nutrient content of the harvested larvae. These findings suggest that mealworm productivity can be enhanced by increasing water feed levels and that bean sprouts may be a superior alternative to lettuce. Full article
