Pineapple pulp residue is one of the country's agro-industrial by-products that is less utilized in ruminant feed due to rigid texture of fiber. The bioprocessing of pineapple pulp using solid-state fermentation by Aspergillus niger improved the texture, palatability and nutritional value of the product. The fermented pineapple pulp product had a 38% crude protein and high organic acids and a 36% decrease in fiber content. Evaluation of the growth performance of growing dairy calves fed with different inclusions of protein-enriched pineapple pulp was carried out using a Randomized Complete Block Design (RCBD) with a total of 16 growing calves in four treatments. Results showed that the calves fed with 50% feed concentrate substituted by protein-enriched pineapple pulp performed best among the four treatments based on average daily gain and feed efficiency
