The results of nutrient digestibility showed significantly lower (P < 0.01) digestibility of crude protein (82.2 ± 1.92 vs. 87.9 ± 2.05%) and crude fat (32.0 ± 2.81 vs. 49.3 ± 2.25%) in the control group compared to the experimental group. Non-significantly lower digestibility was found in dry matter (86.0 ± 3.20 vs. 89.2 ± 3.08%), crude fibre (34.3 ± 3.64 vs. 37.6 ± 2.86%) and ash (56.1 ± 2.49 vs. 58.1 ± 2.47%).
The results confirmed sorption ability of humate fed to pigs. The decrease of coefficients of apparent digestibility in nitrogen substances can lead to decreased amounts of ammonia into the environment of the stables.
