Dietary inclusion of white lupine seeds and their byproducts in rabbits can contribute to EU agricultural sustainability: a review

Abstract

[EN] This review explores the potential of white lupin seeds (Lupinus albus) as a sustainable protein source for rabbit nutrition and examines their effects on growth performance, carcass traits, health status, milk yield, milk composition and nutrient availability. The dietary inclusion of white lupin seeds leads to comparable or superior growth, milk yield, milk composition, nutrient digestibility and digestive health of rabbits, as well as meat quality and carcass outcomes relative to traditionally used protein sources for feeding rabbits, such as soybean meal and sunflower meal. Studies also show that it is possible to use white lupin byproducts, such as the hull and bran, for rabbit diets, which can be convenient in terms of providing an adequate supply of lignocellulose and enhancing the sustainability of rabbit feed, promoting circular economy principles. The cultivation of white lupin can contribute to environmental sustainability by reducing greenhouse gas emissions and the use of synthetic fertiliser. Future research should focus on breeding improvements and comprehensive environmental assessments of white lupin seeds to maximise the benefits of white lupin for rabbit nutrition. These findings support the role of white lupin as a viable and eco-friendly alternative to traditional protein sources, such as soybean meal, which could support productivity and sustainability in rabbit farming.
