摘　　要：初生犊牛消化、免疫系统发育不完善,弱小的犊牛易发生消化道、呼吸系统疾病,影响正常的生长发育,严重者造成终身发育受阻,甚至死亡。抗生素作为饲料添加剂,应用于犊牛日粮中具有抗病与促生长的作用,然而其弊端也日益凸显。近年来,国内研究者陆续探讨了多种营养调节剂如,酸度调节剂、微生态制剂、酶制剂、β葡聚糖和植物提取物等生物活性物质对犊牛的作用,取得了一系列进展,为犊牛营养调控和早期培育方案提供了科学依据和实际技术指导。For newborn calves, the digestive system and immune system are not well developed. The young animals appear weak and suffer from digestive tract and respiratory system diseases, which will affect the normal growth and development, and even cause life-long development blocked or even death. Antibiotics, as feed additives, have the function of disease resistance and growth promotion when they are used in calf diets. However, their disadvantages are increasingly prominent. In recent years, domestic researchers have successively studied the effects of various nutritional regulators, such as acidity regulators, microecological agents, enzyme agents, β-glucan and plant extracts on calves. A series of progress has been made, which provides scientific basis and practical technical guidance for the nutritional regulation and early rearing strategies of calves.
