Livestock production is a critical component of food security in many developing countries, yet the high cost of livestock feed remains a significant challenge. With feed expenses accounting for approximately 70% of production costs, there is an urgent need to identify alternative, cost-effective feed resources. Neem leaf meal (Azadirachta indica A. Juss.), a non-conventional feedstuff, shows promising potential in improving livestock nutrition. This study investigates the chemical composition, mineral content, and amino acid profile of neem leaves to assess their suitability as an alternative feed resource. Proximate analysis revealed that neem leaves contain high dry matter (91.77%) and crude protein (17.84%), indicating their potential as a valuable protein source for ruminants. The mineral analysis showed substantial levels of calcium (1.97%), potassium (1.86%), and iron (230.78 ppm), suggesting the leaves’ contribution to the mineral nutrition of livestock. Amino acid analysis identified glutamic acid (1.821%), aspartic acid (1.333%), and leucine (1.088%) as the most abundant amino acids, with cystine being the first limiting amino acid. These findings underscore the nutritional value of neem leaves, not only as a protein and mineral source but also as a feed ingredient capable of supporting the health and productivity of livestock, particularly in resource-limited settings.
