Mulberry improved feed quality significantly. Nearly 34 percent higher milk yield was recorded when mulberry was provided once a day. Crude protein content in leaves varies from as low as 15% to 28% depending on the variety, age of the leaves and growing conditions. In general, crude protein values can be considered similar to most legume forages.

Fibre fractions are low in mulberry leaves compared to other foliages. A striking feature of mulberry leaves is the mineral content, with ash values up to 25%. Typical calcium contents are around 1.8-2.4% and phosphorus 0.14-0.24%. Espinoza et al. (1999) found potassium values of 1.90-2.87% in leaves and 1.33-1.53% in young stems, and magnesium contents of 0.47-0.63% for leaves and 0.26-0.35% for young stems. Preferred type variety of mullberry is the MORUS NIGRA.
