Ebermast mit unterschiedlicher Proteinversorgung
1999
Abstract. Title ofthe paper: Boar fattening with different protein supply in the diet In the literature numerous studies are found that proof a superior fattening performance and carcass composition for boars compared to female and castrated pigs. The results in the feeding experiment presented here do not confirm this to the same extend. Even with a high protein and lysine supplementation growth performance of boars was lower than in females. Lean content was determined by FOM grading which might underestimate the boars. Lean to fat ratio (areas of M. long dorsi and back fat) however was significantly different between castrates and all boar groups due to the reduced fat deposition. Sensoric tests detected significant boar taint in the majority ofthe samples from male carcasses. Considering the tendency on the market for increasing carcass weights and the risk of boar taint in heavier pigs boar fattening can not be recommended in Germany.
