Table 5: Intake and dry matter in vitro degradability parameters and neutral detergent fiber. and T4 (\(p\) > 0.05), while the concentrations between T1 and T2 were different (\(p\) < 0.05). Acetate and propionate rumin concentrations were affected by the treatments (\(p\) < 0.05). Acetate concentrations decreased when LLL replaced alfalfa hay in 20% (T2) and 10% (T4). However, propionate concentrations increased with both treatments. The highest values of microbial biomass synthesis (MBS) were recorded in T1 and the lowest in T2 (\(p\) < 0.05). Control treatment (T1) showed an increase of 23.0%, 12.0%, and 14.0% in relation to T2, T3, and T4, respectively (\(p\) < 0.05). Partition factor (PF) values were statistically similar between T2, T3, and T4 (\(p\) > 0.05) but different from T1 (\(p\) < 0.05).
