Sugar beet pulp, a major by-product of the sugar industry, represents an important source of dietary fiber for animal nutrition. When combined with molasses, it offers technological advantages such as improved palatability and pellet binding capacity. However, the inclusion of molassed sugar beet pulp in rabbit diets raises concerns regarding the balance between structural fiber and rapidly fermentable saccharides. Available studies indicate that while sugar beet pulp without molasses may contribute to digestive health and feed efficiency, the addition of molasses can increase the risk of digestive disorders and higher mortality rates in growing rabbits, particularly under intensive production conditions. On the other hand, molasses is a natural source of betaine (about 7% of dry matter), acting as a methyl group donor and osmolyte with beneficial effects on lipid metabolism, growth performance and stress resilience. This article evaluates the potential benefits and drawbacks of incorporating molassed sugar beet pulp into rabbit diets, highlighting the need for cautious use at low inclusion levels to exploit its technological and nutritional properties without compromising animal health and performance.
