Kleegrassilage als proteinreiches Raufutter in der Mastschweinefütterung

Raufutter reichert die Haltungsumwelt an, verringert aggressive und stereotype Handlungen und es hat positive Effekte im Verdauungssystem von Mastschweinen. Zudem ist es ein regionales Futtermittel mit geringer Nahrungsmittelkonkurrenz. Das Ziel war es, zu prüfen ob Silage aus Kleegras zur Proteinversorgung von Schweinen beitragen kann und ob eine Fütterung von Silage bereit in der Aufzucht von Vorteil in Bezug auf die Mastleistung und Schlachtkörperqualität ist.

Roughage has advantages in pig feeding. It enriches the environment, reduces the aggressive and stereotypic actions and has positive effects in the digestive system. The aim was to test whether grass-clover silage can also contribute to the protein supply of pigs and whether habituation to silage in rearing is beneficial in terms of fattening performance and carcass quality. For this purpose, four fattening runs with 80 pigs each were carried out. In the first two runs (trial 1), the use of grass-clover silage and straw as roughage were compared. In the second two runs (trial 2), pigs were fed grass-clover silage either beginning at birth or beginning at 50 kg body mass. There were no differences of fattening performance and carcass quality between the feeding groups in each trial. The protein-rich grass-clover silage can contribute to the diet of fattening pigs.
