Zum Einfluss von Mutterkorn im Futter auf Absetzferkel und Masthähnchen

Two preliminary tests were conducted with piglets and chicken to study the influence of feeding ergot, which was specified concerning alkaloid content and pattern, on growth performance and health parameters. Treatments were 5 ergot concentrations in the diets (0; 0.05; 0.1; 0.2; 0.4%) which were fed to 5×16 piglets for 35 days and 5×28 chicken for 21 days. A content of 0.4% ergot in the diet decreased feed intake and growth performance of piglets significantly. Contents of 0.1% and 0.2% ergot in the diet showed a tendency towards improved weight gain as compared to controls. Feed to gain ratio was found to be the lowest in the group with 0.2% ergot in the diet. In the study conducted with chicken significant effects of ergot feeding on growth performance were not detected. With increased ergot concentrations in the diet the weight of hearts decreased, which proved to be significant only at a level of 0.2 % ergot in the diet. Moderate to severe inflammations were found in the proximal duodenum of the ergot fed groups, which, however, were not dosedependent. Further studies with ergot from other sources differing in alkaloid content and pattern are necessary to evaluate toxic alkaloid levels for the various animal species or categories.
