Effect of feeding restriction on growth and dressing percentages in Mexican hairless pig

Twenty-four male Mexican hairless pigs, weighing 16 ± 1.12 kg, were used to evaluate growth performance and carcass yield in pigs fed 2 (L), 3 (M) and 4 (H) times the Metabolizable Energy (ME) required for maintenance. The pigs were assigned randomly to two experimental rearing systems (indoors and...

Description
Summary:Twenty-four male Mexican hairless pigs, weighing 16 ± 1.12 kg, were used to evaluate growth performance and carcass yield in pigs fed 2 (L), 3 (M) and 4 (H) times the Metabolizable Energy (ME) required for maintenance. The pigs were assigned randomly to two experimental rearing systems (indoors and outdoors). They were fed daily according to their respective feeding regimen (FR). The indoor pigs were fed ad libitum with chopped star grass forage ( Cynodon nlemfuensis ). The outdoor pigs had access during 16 h to a paddock of star grass. The pigs were slaughtered when they achieve 70 kg of live weight. No significant differences between indoors and outdoors were observed in any of the variables evaluated ( P  > 0.05). A significant reduction of daily live weight gain ( P
