The original version of this article unfortunately contained a mistake. The third bullet under the section Materials and Methods should read “Soybean oil (SOY) group: Soybean oil was administered via oral gavage (2ml/kg) during the nursery period before expansion (an interval of 40 days), and during the expansion (period of 5 days) + retention period (period of 12 days—a total of 57 days)” instead of “Soybean oil (SOY) group: Soybean oil was administered via oral gavage (0.2 ml/kg) during the nursery period before expansion (an interval of 40 days), and during the expansion (period of 5 days) + retention period (period of 12 days—a total of 57 days)”.

The authors apologize for the mistake.
