Abstract: Objective In order to study the feeding method suitable for experimental cats. Method 18 female British short haired cats aged 7 months were randomly divided into three groups, with 6 cats in each group. The experiment was conducted in three ways, namely, cage breeding, regular release of active breeding and captive breeding. The total duration of the experiment was 8 weeks. The body weight, average daily gain, average daily food intake, average daily water intake and blood physiological and biochemical indexes of experimental cats in each group were measured and analyzed. Result The weight of 7-9 month old experimental cats was not significantly affected by different feeding method;in the first week of the experiment, the average daily increase of the regular release of active breeding group was significantly higher than that of the captive group ( P < 0. 05 ) . From the third week, there was no significant difference in growth performance indicators between the captive group and the regular release of active breeding group;The weight growth rate of the experimental cats in the cage group was slower than that of the other two groups, and there was a significant difference between the cage group and the other two groups at the 4th, 6th and 8th weeks ( P < 0. 05) ,In terms of daily average food intake, the regular release of active breeding group in the first week was significantly higher than the cage group (P< 0. 05) , the regular release of active breeding group in the second week was significantly higher than the cage group and the cage group (P<0. 01) , and in terms of daily average water consumption, the regular release of active breeding group in the fourth week was significantly higher than the cage group ( P < 0. 05) ;the lymphocyte ratio ( LY%) test result showed that the captive group was significantly lower than the regular release of active breeding group and the cage group ( P<0. 01) , the number of neutral cells (NE) test result showed that the captive group was significantly higher than the cage group (P<0. 05) , and the platelet distribution width ( PDW) test result showed that the captive group was significantly lower than the regular release of active breeding group and the cage group ( P < 0. 05 ) ; the total cholesterol ( T-CH) test result showed that the caged group was significantly lower than the cage group with regular release of active breeding combination ( P < 0. 05) . Conclusion Regular release of active breeding is suitable for long-term rearing of experimental cats.

摘要： 目的 研究适合实验用猫饲养的方式。 方法 将 18 只 7 月龄的英国短毛猫雌猫随机分成 3 组,每组 6 只,分别采用笼养、定期放养以及圈养等 3 种方式进行饲养,实验总共为 8 周。 测定并分析比较各组实验猫的体质量、平均日增重、日均采食量、日均饮水量、血液生理生化指标。 结果 饲养方式的不同不会对 7 ~ 9 月龄实验猫体质量造成显著影响(P>0. 05) ;实验第 1 周,定期放养组平均日增重要显著高于圈养组(P<0. 05) ,第 3 周开始,圈养组和定期放养组在生长性能指标上并没有表现出显著差异;笼养组实验猫体质量增长速度与另外两组相比增长较慢,于第 4、6、8 周分别产生了显著差异(P<0. 05) ,而在日均采食量方面,第 1 周定期放养组显著高于笼养组( P< 0. 05) ,第 2 周定期放养组极显著高于圈养组和笼养组(P<0. 01) ,在日均饮水量方面,第 4 周定时放养组显著高于笼养组(P<0. 05) ;淋巴细胞比率( LY%)检测结果显示,圈养组极显著低于定期放养组和笼养组( P< 0. 01) ,中性细胞数(NE)检测结果显示,圈养组显著高于笼养组(P<0. 05) ,血小板分布宽度( PDW)检测结果显示,圈养组显著低于定期放养组和笼养组(P<0. 05) ;总胆固醇( T-CH) 检测结果显示,圈养组显著低于定期放养组和笼养组( P< 0. 05) 。结论 定时放养方式更适合实验用猫的长期饲养。
