【摘要】 试验旨在研究饲粮中添加植物甾醇对猫安全性以及减肥效果的影响。适口性试验：选取12只中华田园猫单独进行双碗适口性试验，分别饲喂含植物甾醇0、0.15%的饲粮，测定首选日粮及采食量，试验周期为2 d。安全性试验：选取20只健康成年中华田园猫，随机分为3组，分别饲喂含植物甾醇0、0.15%、1.50%的饲粮，自由采食与饮水；试验测定采食量、体重变化和血液指标，试验周期为28 d。减肥效果试验：采用安全性试验中确定的植物甾醇适宜添加剂量0.15%，选取12只肥胖的中华田园猫，随机分为2组，分别在饲粮中添加0、0.15%的植物甾醇，根据体重计算代谢能并进行限制能量饲喂，试验测定采食量、体重变化和血液指标，试验期为30 d。适口性试验结果显示：植物甾醇不影响猫的采食量（P>0.05），首选日粮添加植物甾醇的日粮显著高于对照日粮（P<0.05）。安全性试验结果显示：与对照组相比，饲粮中添加0.15%和1.50%植物甾醇对成年猫的生理状态、采食量、体重以及血常规、血生化等指标均无显著影响（P>0.05）。减肥试验结果显示：与对照组相比，从第10天开始，饲粮中添加0.15%的植物甾醇加快了猫的减重速率（P<0.05）；与第0天相比，在第30天时饲粮中添加0.15%的植物甾醇使猫的血清三酰甘油水平下降17.3%，体况评分显著下降（P<0.05）。综上所述，在猫粮中添加0.15%植物甾醇不影响适口性；在猫粮中添加0.15%和1.50%植物甾醇具有良好的安全性；在猫粮中添加0.15%植物甾醇可以提高减重速率，改善肥胖猫体况评分。更多还原

【Abstract】 The aim of this experiment was to study the effects of adding phytosterols to diets on cat safety and weight loss. Palatability test: 12 Chinese field cats were selected for the double-bowl palatability test, fed diets containing 0 and 0.15% phytosterols respectively, and the preferred diets and feed intake were determined, with a test period of 2 d. Safety test: 20 healthy adult Chinese field cats were randomly divided into 3 groups, fed diets containing 0, 0.15% and 1.50% phytosterols respectively, and fed and drank freely. The test measured feed in-take, body weight change and blood index, the test cycle is 28 d. Weight loss effect test: using the safety test to determine the appropriate amount of phytosterol additive 0.15%, selected 12 overweight and obese Chinese field cats, randomly divided into 2 groups, respectively, added 0, 0.15% phytosterol in the diet, according to the body weight of the metabolic energy calculation and energy-limiting feeding. The test measured feed intake, body weight change and blood indexes, and the test pe-riod was 30 days. The results of the palatability test showed that phytosterols did not affect the cat′s feed intake(P>0.05), and the diet with added phytosterols was chosen first more frequently than the control diet(P<0.05). The results of the safety test showed that the addition of 0.15% and 1.50% phytosterols to the diets did not significantly(P>0.05) affect the physiological status, feed intake, body weight, as well as blood routine and blood biochemistry indexes of the adult cats compared with the control group. The results of the weight loss test showed that the addition of 0.15% phytosterols to the diet accelerated the rate of weight loss in cats from day 10 onwards compared with the control group(P<0.05). The addition of 0.15% phytosterols to the diet reduced the serum triglyceride level of cats by 17.3% at day 30 com-pared with day 0. The addition of 0.15% phytosterols to the diet reduced the body condition score of cats by 17.3% compared with day 0. The addition of 0.15% phytosterols to the diet reduced the body condi-tion score of cats by 17.3% compared with day 0. Sterols resulted in a significant decrease(P<0.05) in the body condition score of cats. In conclusion, the addition of 0.15% phytosterols to cat diets did not dif-fer palatability; the addition of 0.15% and 1.50% phytosterols to cat diets has good safety; the addition of 0.15% phytosterols to cat diets can increase the rate of weight loss, and improve body condition scores in obese cats.更多还原
