The effect of different weaning strategies on piglet growth, feed intake and gut health.

The present study evaluated the effects of weaning strategy on piglet growth performance, onset of feed intake, and intestinal health. A total of 254 crossbred piglets were used and the experimental period lasted 45 days. The piglets were assigned to the fallowing treatments: early strategic weaning (ESW, n = 85), piglets weaned at 16 days of age and transferred to the pre-nursery unit; strategic segregated weaning (SSW, n = 85), piglets weaned at 21 days of age and kept in the farrowing crate until 24 days of age; and conventional weaning (CW, n = 84), piglet weaned at 24 days of age and transferred directly to the nursery unity; this experimental group was used as a control.
