*
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 small letters (a, b) differ statistically at the level of P ≤ 0.05. The whole rearing period of piglets comprises the time from farrowing to the 21st day of lactation. NS, impact statistically non-significant.
