Abstract: This experiment was conducted to investigate the effects of dietary supplementing bovine colostrum powder （BCP） on growth performance， fecal scores， blood routine indicators， serum biochemical markers， antioxidant capacity，anti⁃inflammatory capacity and immune function of adult cats. Sixteen adult neutered British blue shorthair cats（eight males and eight females），were randomly divided into two groups with eight replicates in each group. The cats in the control group were fed a basal diet，and the cats in trial group were fed with basal diet with 0.05% BCP. The pretrial period lasted for 7 days and the formal trial period lasted for 28 days. One day before formal trial period，Initial body weights were measured. The daily feed intake of each cat was recorded during the trial. On days 14 and 28，after fasting，body weight was measured and blood samples were collected for serum biochemistry， blood routine，serum antioxidant，anti⁃inflammatory and immune indicators. Fecal scores were measured on days 1， 7，14，21 and 28. The results are as follows：（1）Compared with the control group，there was no significant effect on the growth performance and fecal score of the experimental group（P>0.05）.（2）The platelet distribution width，total platelet count and platelet hematocrit were significantly increased on day 14（P<0.05），while the mean volume of red blood cells decreased significantly on day 28（P<0.05）.（3）On the 14th day，in terms of the experimental group，the value of urea nitrogen/creatinine（BUN/GREA）increased significantly（P<0.05）（. 4）The levels of malondialdehyde in the experimental group were significantly decreased on the 14th and 28th days（P<0.05）.（5）On the 28th day，in terms of the experimental group，the levels of interleukin 4 and interleukin 10 were significantly increased（P<0.05）， and the levels of tumor necrosis factor⁃α were significantly decreased（P<0.05）（. 6）The level of complement 3（C3）in the experimental group increased significantly on day 14（P<0.05）. It is concluded that adding 0.05% BCP to the diet of adult cats had no negative impacts on growth performance and nutrient digestion of adult cats，but can improve the ability of blood nitrogen metabolism，improve the body's anti ⁃ inflammatory，antioxidant and immune functions， enhance the ability of adult cats to cope with environmental stress，and care for the health of adult cats.

摘要： 该研究旨在探究饲粮中添加牛初乳粉（Bovine colostrum powder, BCP）对成猫的生长 性能、粪便评分、血常规指标、血清生化指标、抗氧化能力、抗炎能力和免疫功能的影响。选取 16只成年绝育英国短毛猫（蓝猫），公母各半，随机分成2组，每组8个重复。分别饲喂基础饲 粮（对照组）和基础饲粮+0.05% BCP（试验组）。预试期7 d，正试期28 d。正试期前1 d，称取每 只猫的空腹初始体重；试验期间记录每只猫的日采食量；第14和28天称取空腹体重后，采集血 液样本用于检测血常规、血清生化、抗氧化、抗炎和免疫指标；第1、7、14、21和28天测定粪便评 分。结果表明：（1）与对照组相比，试验组成猫生长性能和粪便评分无显著影响（P>0.05）。（2） 试验组第14天血小板分布宽度和第28天血小板总数、血小板压积均显著升高（P<0.05）；而第 28天红细胞平均体积显著降低（P<0.05）。（3）试验组第14天尿素氮/肌酐（BUN/GREA）值显著升 高（P<0.05）。（4）试验组第14和28天丙二醛水平均显著降低（P<0.05）。（5）试验组第28天时，白 细胞介素4和白细胞介素10水平显著升高（P<0.05），肿瘤坏死因子?α水平显著降低（P<0.05） （6）试验组第14天补体3（C3）水平显著升高（P<0.05）。综上所述，饲粮中添加0.05% BCP不会 对成猫的生长性能和营养物质消化产生负面影响，可改善血液氮代谢能力、提高机体抗炎、抗 氧化和免疫能力，增强成猫应对环境应激的能力，呵护成猫的健康。
