*Impact statistically significant at the level of P ≤ 0.05.

^**Impact statistically highly significant at the level of P ≤ 0.01. Means designated with different capital letters (A,B,C) differ statistically at the level of P ≤ 0.01. The whole rearing period of piglets comprises the time from farrowing to the 21st day of lactation. NS, impact statistically non-significant.
