Effect of energy intake during gestation on performance and blood parameters of primiparous sows

The relationship between productivity and metabolic status, especially in gilts, is of great interest. Greater energy intakes during late gestation have been linked to lower lactational feed intake, resulting in catabolism and a poorer reproductive outcome in the next parity1,2,3.

The aim of the study was to investigate the effects of energy intake in primiparous sows’ performance and metabolic state.
