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.
