The objective of the research was to investigate the effect of supplementation on some acute-phase proteins, haptoglobin and all electrophoretic parameters in young Charolaise bulls.
Sixty bulls were divided into two equal groups: the control group (CG) receiving the base diet without yeast supplementation and the diet supplementation group (YG) receiving the base diet with 5g of supplementation. The base diet was total mixed ration allocated at 11.85 kg per animal per day. Blood samples were collected from all bulls on day 0 before the start of the diet supplementation, and on days 20 and 40 after the start. Total proteins, albumin, globulin fraction (α1-, α2-, β1-, β2- and γ-globulins), albumin: globulin ratio (A: G) and haptoglobin were determined.
Two-way analysis of variance showed a significant effect of the yeast feeding time on all studied parameters except α2-globulins in both groups. The YG showed a higher average concentration of total proteins, albumin and A: G and a lower average concentration of γ-globulins and haptoglobin than the CG.
These results indicated the beneficial effect of the on the inflammatory status of the young bulls, which showed an adequate response in serum levels of the acute-phase proteins tested.
本研究的目的是调查补充剂对夏洛来幼公牛某些急性期蛋白、触珠蛋白和所有电泳参数的影响。
60头公牛被分为两组，每组数量相等：对照组（CG）饲喂不添加酵母的基础日粮，日粮补充组（YG）饲喂添加5克补充剂的基础日粮。基础日粮为全混合日粮，每头动物每天分配11.85千克。在日粮补充开始前的第0天，以及开始后的第20天和第40天，从所有公牛采集血样。测定总蛋白、白蛋白、球蛋白组分（α1-、α2-、β1-、β2-和γ-球蛋白）、白蛋白：球蛋白比率（A：G）和触珠蛋白。
双向方差分析表明，酵母投喂时间对两组中除α2-球蛋白外的所有研究参数均有显著影响。与对照组相比，日粮补充组的总蛋白、白蛋白和A：G平均浓度较高，γ-球蛋白和触珠蛋白平均浓度较低。
这些结果表明补充剂对幼公牛的炎症状态具有有益作用，在所检测的急性期蛋白血清水平上显示出充分的反应。
