Effect of suckling intensity of primiparous sows on production performance during current and subsequent parities

Increased suckling intensity increased litter weight gain but reduced piglet ADG. Following lactations were not negatively affected by increased suckling intensity of the first lactation. Loss of sow body reserves was reduced for the second lactation.
