A semi-solid animal feed block is provided to an animal as a feed supplement or as a complete feed. The feed block is formed of a liquid binder containing denatured wheat flour protein and sugar, and a nutrient mixture of at least one animal feed component. The denatured protein and the sugar bind the nutrient mixture to form the semi-solid animal feed block as a single mass. The nutrients may be formulated to promote digestive tract development of a recently weaned livestock animal, such as a piglet.
