摘　　要：在肉牛养殖中,犊牛拉稀是以食物消化不良、拉稀为主要临床症状的犊牛胃肠道疾病,拉稀是哺乳犊牛和断奶犊牛的常发病,比肺炎和脐带炎的发病率都高,约占犊牛发病率80%左右。糟渣复合型饲料中的枯草芽孢杆菌、嗜酸乳杆菌能促进肠道有益微生物的繁殖和生长,有效预防犊牛拉稀,提高犊牛繁殖成活率。在甘肃武威顶乐牧业有限公司牧业二场选取60头妊娠70日龄的西杂母牛作为试验牛,观察记录妊娠牛、哺乳母牛、犊牛排粪情况,对出生15日龄内、90~120日龄内犊牛综合拉稀率、犊牛粪便进行测定和综合评分。试验组比对照组(0~15日龄)哺乳犊牛拉稀率降低5.3%,断奶犊牛拉稀率降低2.3%,减少了犊牛胃肠消化道疾病,有效预防犊牛拉稀,提高了饲料消化率。在怀孕牛日粮中添加糟渣复合型饲料,可有效预防犊牛拉稀,提高犊牛成活率。In beef cattle production,calf diarrhea is a gastrointestinal disease with dyspepsia and diarrhea as the main symp-toms.Lactating calves are more prone to diarrhea,accounting for about 80%of the incidence rate of calves.Bacillus subtilis and Lactobacillus acidophilus in the complex feed of residue can promote the proliferation and growth of beneficial bacteria in the in-testine,effectively prevent calf diarrhea,and improve calf survival rate.Twenty 70 day pregnant Western hybrid cows were se-lected from the second animal husbandry farm of Gansu Wuwei Dingle Animal Husbandry Co.,Ltd.The defecation status of pregnant cows,lactating cows,and calves was measured and observed;The comprehensive diarrhea rate and fecal score of calves within 15 days of birth and within 90 to 120 days of age.The application of residue composite feed can reduce the diarrhea rate of 0-15 d old calves by 5.3%,weaned calves by 2.3%,reduce gastrointestinal diseases in calves,improve feed digestibility,and effectively prevent calf diarrhea.Feeding pregnant cattle with a complex feed of dregs can effectively prevent calf diarrhea and improve calf survival rate.
