Juice from silage in green bio refineries - a potential feed ingredient in liquid diets to weaned pigs

Akerfeldt, Magdalena Presto; Friman, Johanna; Dahlstrom, Frida; Larsen, Anne; Wallenbeck, Anna


The objective of this study was to evaluate silage juice from green bio refineries in liquid diets to pigs and its' effect on growth, cleanliness and health. Ninety-six (L x Y) x H organically raised pigs were fed either a control diet (C-diet) or a silage feed juice diet (SFJ-diet). The C-diet consisted of a commercial feed mixed with water prior to feeding. The SFJ-diet consisted of a lower ration of commercial feed mixed with silage feed juice (SFJ) instead of water, theoretically replacing 10% of the dietary crude protein content. All pigs consumed the juice and grew similarly, on average 0.48 kg/day. SFJ pigs were significantly dirtier on their back and head than C pigs (P < 0.001 for all), but cleanliness in the rectum area and in the pen did not differ. Silage juice had only minor effects on hygienic measures and could be a potential local feed ingredient to pigs.
