Optimization of piglet nest use under organic husbandry conditions

Nest use increased from the first to the third day after birth. The piglet nest was used more frequently during the day than at night, and piglets spent significantly more time in the piglet nest in winter than in summer. • Temporary confinement of piglets in the nest resulted in more frequent nest use. • Different types of heating and lighting of the nest showed no clear effects on piglet nest use and piglet behavior in the nest. • Floor heating used less energy than lid heating.
