摘　　要：试验旨在研究不同水平的酵母锗培养物对仔猪血液指标的影响。试验选用100头体况良好的体重在6 kg左右的杜×长×大三元杂交仔猪,将其随机分为5组,每组20头仔猪公母各半。其中对照组饲喂基础日粮,其余4个试验组分别在基础日粮中分别添加浓度为15、25、35、45 mg/kg的酵母锗培养物。试验结果表明:与对照组相比,当仔猪日粮中的酵母锗培养物的浓度达到35 mg/kg时,血液中WBC含量、LYM的百分数在仔猪的各个饲养阶段均有显著提高(P<0.05),LYM数有极显著提高(P<0.01);血清中的TP及ALB的含量极显著的提高(P<0.01),BUN和TG的含量极显著的降低(P<0.01),CHO的含量显著降低(P<0.05);血液中的ALT和ALP的活性均有显著的提高(P<0.05)。综上所述,仔猪日粮中添加适量酵母锗培养物可以有效的提高仔猪的免疫能力和仔猪对蛋白质及脂肪的吸收利用能力,综合其他因素考虑,断奶仔猪日粮中添加酵母锗培养物的最适浓度为35 mg/kg。This trial was designed to study the effect of different levels of yeast germanium on piglets＇ blood indicators. A total of 100 piglets with a body weight of about 6 kg were collected and randomly divided into five groups. Each group had 20 piglets that had the half of male female. The control group was fed with basal diet, and the other four groups were respectively supplemented with yeast germanium at a concentration of 15 mg/kg, 25 mg/kg, 35 mg/kg and 45 mg/kg. Compared with the control group, when the concentration of the yeast germanium culture in the diet of the piglets reached 35 mg/kg, the percentage of WBC and LYM in the blood increased significantly in each feeding stage of the piglets （P〈0.05）, and the LYM number was significantly （P〈0.01）; The contents of TP and ALB in serum were significantly increased（P〈0.01）, the contents of BUN and TG were significantly decreased（P〈0.01）, and the content of CHO was significantly decreased（P〈0.05）. ALT and ALP activity in the blood were significantly improved （P〈0.05）. In summary, the piglets＂ diets add appropriate amount of yeast germanium can effectively improve the pig＇s immune capacity and piglets on protein and fat absorption and utilization. Considering other factors, the optimum concentration of yeast germanium in weaned piglets was 35 mg/kg
