![]() ![]() The average daily gain of all the pigs was over 1000 g day − 1 in the experimental period but no difference between silage juice fed and control group was found. Feed allowance was ad libitum until it reached 33.6 MJ net energy day −1 per pig which was kept as the maximum feed allowance until slaughter. The silage juice was included into liquid feed of 112 fattening pigs from 62 kg live weight until slaughter (124 kg live weight) and compared to 96 pigs on a conventional control diet. Grass silage was fractionated with a twin-screw press to liquid and solid fractions. ![]() The aim of the present study was to evaluate whether silage juice could provide a new sustainable diet ingredient for fattening pigs. ![]() The digestible nutrients in grasses are embedded in a fibre matrix not digestible to pigs, but suitable processing could alleviate this. Due to global challenges related to growing human population, sustainable feed materials for pigs are actively searched and grasses as a high yielding biomass have been seen as an interesting addition to pig feeds. Traditionally grass has been considered a suitable feed only for ruminants. ![]()
