An experiment with five litter-mate barrows showed that severe reduction in feed intake and growth rate accompanied the inclusion of either 1.0 or 2.0% ergot in the ration. Levels of 0.10 and 0.05% ergot allowed moderate feed intake and weight gain but not equal to the pig fed the ergot-free ration. A subsequent experiment involving five lots of four litter-mate barrows each, indicated the possibility of reduced feed intake and growth performance by growing-finishing pigs fed rations containing 0.05 - 0.10% ergot. This was substantiated by a N-balance experiment in which control pigs retained 1.54 gm more N daily than pigs fed 0.10% ergot. The total alkaloid content of the ergot used in these experiments was 0.292%; the predominant alkaloid (71%) being ergocristine.
一项用五头同窝仔猪进行的试验表明，日粮中添加1.0%或2.0%的麦角会导致采食量和生长速度严重下降。添加0.10%和0.05%麦角的水平可使采食量和体重适度增加，但不如饲喂无麦角日粮的猪。随后一项试验，每组用五批、每批四头同窝仔猪，结果表明，生长育肥猪饲喂含0.05 - 0.10%麦角的日粮，有可能降低采食量和生长性能。这一点在氮平衡试验中得到了证实，在该试验中，对照猪每天比饲喂0.10%麦角的猪多保留1.54克氮。这些试验中所用麦角的总生物碱含量为0.292%；主要生物碱（71%）为麦角晶碱。
