It all starts with the sow before weaning!
The sow will transmit the first key elements of defence to the piglet: immunity (passive via colostrum) and microbiota (vertical transmission via faeces).
Rapid absorption of colostrum, in sufficient quantity and quality, and the establishment of a diverse and stable microbiota promote immunity, intestinal maturation and resistance to infection. Early ingestion of feed under the mother's care is also essential to prepare the piglet to consume and digest the 1st age feed.
