  1. Data expressed as Mean (n = 3), Mean values in the same column with different superscript differ significantly (P < 0.05)
  2. 1CS, 0 g kg−1 PSM (Prosopis cineraria seed meal); PSM5, 50 g kg−1 PSM; PSM7.5, 75 g kg−1 PSM; PSM10, 100 g kg−1 PSM
  3. 2Amylase activity is expressed as micromole of maltose released/min/mg protein
  4. 3Protease activity is expressed as micromole of tyrosine released/min/ mg protein
  5. 4Lipase activity is expressed as unit/mg protein
  6. 5ADC, Apparent digestibility coefficient;
  7. 6ADCP, Apparent digestibility coefficient of crude protein; 6ADCL, Apparent digestibility coefficient of crude lipid/ether extract
