LN = Leymus as the only roughage with No calcium salts of fatty acid, LC = Leymus as the only roughage with Calcium salts of fatty acids, AN = Alfalfa replace 50% leymus with No calcium salts of fatty acids, AC = Alfalfa replace 50% leymus with Calcium salts of fatty acids.
p-value: Treatment: P value of Duncan’s multiple comparisons between diets treatments and different lowercase letters within the same row denote significant differences between the treatments; alfalfa, CASF and alfalfa × CSFA: the factorial analysis of crude protein levels, CSFA and their interaction.
