摘　　要：通过32头泌乳奶牛饲喂生化黄腐酸的对比试验。结果表明,生化黄腐酸对奶牛乳房炎、隐性乳房炎有效率达100%,治愈率达80%;试验组比对照组产奶量提高13.84%(<0.05);校正体重后试验组比对照组产奶量提高14.94%(<0.05);提高饲料转化率13.79%(<0.05);每头奶牛每年增加的经济效益=产奶量提高效益+牛奶级别提高效益+防治乳房炎、隐性乳房炎减少的牛奶损失=881.45元+400元+377.86元=1659.31元,增收效益显著。A comparative feeding trial was done by using 32 lactating dairy cows fed with biochemical fulvic acid. The results showed that the cure efficiency rate of biochemical fulvic acid to clinic mastitis and subclinic mastitis was 100% and curative rate was 80%. The milk output of experiment group was 13.84% higher than that of control group, the difference was distinct（P〈0.05）. Compared with control group, the milk output increased by 14.94% and food conversion rate increased by 13.79% in experiment group after weight adjustment, the differences were significant（P〈0.05）. The annually increased profit amounts to 1659.31RMB Yuan per head, The significantlly increased profit include increased milk output, improved milk scale and decreased lost through preventing clinic and subclinic mastitis, to which the amount is 881.45, 400.00, 377.86 RMB Yuan separately.
