Dogs hospitalized in veterinary clinics are likely to show signs of separation-induced anxiety from hospitalization. The study assessed the effect of dog-appeasing pheromone (DAP) on 10 typical separation-related behavioral signs in hospitalized dogs. A DAP treated group (n = 24) was compared with a placebo control group (n = 19). There was overall amelioration of the signs without ‘vigilance’ and ‘anorexia’ in the DAP-treated dogs; marked decreases were noted in elimination (P = 0.038), excessive licking (P = 0.005), and pacing (P = 0.017). The results suggest that the use of DAP could decrease separation-induced anxiety, distress, and fear in inpatients, and possibly facilitate recovery in hospitalized dogs.  相似文献

This study was performed to determine the effect of the dietary inclusion of various sources of green tea on growth, body composition and blood chemistry of the olive flounder. Twenty-five juvenile fish were distributed into each of 15 180 l flow-through tanks. Five experimental diets with triplicates were prepared: control, raw leaves, dry leaves, by-product and extract. The 5% various sources (raw leaves, dry leaves and by-product) of green tea were included in the experimental diets at the expense of 5% wheat flour. The extract was diluted with water and mixed with the ingredients to maintain 5% green tea at the same concentration as in the other diets. Weight gain and specific growth rate of fish fed the control diet and experimental diet containing extract were higher than those of fish fed the diets containing raw and dry leaves and by-product. Feed and protein efficiency ratio for fish fed the control diet and diet containing extract was higher than for fish fed the diets containing raw leaves and by-product. The level of low-density lipoprotein (LDL) cholesterol of fish fed the control diet was higher than that of fish fed the other diets containing various sources of green tea. The glutamic oxaloacetic transaminase (GPT) concentration of fish fed the diets containing raw leaves and extract was lower than that of fish fed the control diet. Crude lipid content of liver in fish fed the control diet was higher than that in fish fed the diets containing raw and dry leaves and by-product but was not significantly different from that of fish fed the diet containing extract. Dietary inclusion of extract was the most effective way to improve growth and feed utilization of the olive flounder among the various sources of green tea, and all sources of green tea were effective in lowering serum LDL cholesterol and GPT of the fish.  相似文献

The purpose of this study was to evaluate behavior problems of the Jindo dog, the native dog of Korea, based on an owner''s survey and their effect on pet relinquishment. To live a better life with their own pet and prevent relinquishment, it is important to understand the innate behavior characteristics of dog breed and the potential causes of relinquishment. Information concerning various factors and demonstration of the five most common behavior problems was collected via 189 completed questionnaires. No factors significantly affected the demonstration of behavior problem. A total 151 of 189 dogs had behavior problems (79.9%) and 38 dogs did not have behavior problems (20.1%). Among 151 dogs, 139 dogs showed single behavior problem (92.1%). They were ''excessive excitability'' (46.8%), ''excessive vocalization'' (30.2%), ''inappropriate elimination'' (17.3%), ''destructive behavior'' (4.3%), and ''aggressive behavior'' (1.4%), respectively. In addition, 12 dogs showed two concurrent behavior problems (7.9%) According to the results, the relinquishment of Jindo dogs was not significantly associated with canine behavior problems, which is the single greatest risk factor of relinquishment in general. The possible reasons for potential behavior problems include improper raising, lack of socialization, and insufficient dog training classes, therefore canine behavior would be improved by owner education.  相似文献

A 15-month-old female German Shepherd dog showing compulsive tail chasing was treated with a treatment protocol of pharmacological therapy (using clomipramine) in conjunction with behavioral and environmental management. The responses to the treatment protocol were assessed once a week for 7 weeks in respects to behavioral conditions and the frequency of bouts and its duration. The behavior history including mother, father, and her littermates were also evaluated for the apparent diagnosis. The compulsive tail chasing of the patient dog was improved on the aspect of behavioral condition and gradually decreased in the frequency and duration of bouts. However, in the mid of treatment, the animal showed an aggressive behavior as a concurrent sign associated with compulsive tail chasing.  相似文献

Compensatory growth of juvenile olive flounder, Paralichthys olivaceus L., and changes in proximate composition and body condition indexes of fish during fasting and after refeeding were investigated during the summer season. Groups of 25 fish each (initial body weight of 16 g) were randomly distributed into fifteen 180‐L flow‐through tanks. Fish were fed the experimental diet containing crude protein 46.9% and crude lipid 8.0% with estimated energy level of 14.6 kJ/g diet for 6 d/wk. Five treatments in triplicate were prepared for this study: C, S1, S2, S3, and S4. Fish in the control group (C) were hand‐fed to apparent satiation twice daily. Fish in treatments S1, S2, S3, and S4 experienced 1, 2, 3, and 4 wk of starvation and were then hand‐fed to apparent satiation twice daily during the remaining 7, 6, 5, and 4 wk of the experiment, respectively. A group of starved fish in the similar size was stocked and fasted throughout the 8‐wk feeding trial for chemical and blood analysis. The feeding trial lasted for 8 wk. Weight of fish linearly decreased with week of starvation (P < 0.0001). Linear relationship between condition factor (CF) and hepatosomatic index (HSI) against week of starvation was observed in the starved group of fish. Survival was not significantly (P > 0.05) affected by feeding strategy. However, weight gain and specific growth rate (SGR) of olive flounder in C, S1, and S2 were significantly (P < 0.05) higher than those of fish in S3 and S4. The poorest weight gain and specific growth rate (SGR) were obtained in fish of S4. Feed consumption of olive flounder in C, S1, and S2 was significantly (P < 0.05) higher than that of fish in S3 and S4. Feed efficiency, protein efficiency ratio, and protein retention of olive flounder in C and S1 were not significantly (P > 0.05) different from those of fish in S2 but significantly (P < 0.05) higher than those of fish in S3 and S4. Hematocrit, CF, and HSI of olive flounder were not significantly (P > 0.05) affected by feeding strategy. Chemical composition of fish was not significantly (P > 0.05) affected by feeding strategy. In considering these results, it can be concluded that juvenile olive flounder have the ability to fully compensate for 2‐wk feed deprivation during the summer season. Besides, feed efficiency in fish fed for 7 and 6 wk after 1‐ and 2‐wk feed deprivation was comparable to that in fish fed for 8 wk.  相似文献

A 10‐wk feeding trial to determine the effect of daily feeding ratio on growth and body composition of subadult olive flounder fed the extruded pellet (EP) was performed during the summer season. Thirteen flounder (an initial body weight of 319 g) per tank were distributed into fifteen 500‐L flow‐through tanks. Five treatments of feeding ratio in 5% decrement were prepared in triplicate: 100 (satiation), 95, 90, 85, and 80% of satiation. Fish in the control group (100% of satiation) were hand‐fed to apparent satiation twice a day. Then, feed allowance in the rest of the four groups was determined based on average feed consumption of fish in the control group. Weight gain of fish fed to 100% of satiation was significantly (P < 0.05) higher than that of fish fed to 85 and 80% of satiation but not significantly (P > 0.05) different from that of fish fed to 95 and 90% of satiation. Serum total protein, glucose, and glutamic pyruvic transaminase were not significantly (P > 0.05) affected by feeding ratio but triglyceride and glutamic oxaloacetic transaminase were. In considering these results, it can be concluded that optimum daily feeding ratio for growth of subadult olive flounder seemed to be 90% of satiation when fish were fed the EP twice a day during the summer season.  相似文献

The effect of feeding ratio on growth and body composition of juvenile olive flounder fed extruded pellets was determined during the summer season. Thirty juvenile olive flounder (initial body weight of 17 g) per tank were distributed into 21, 180-l flow-through tanks. Seven treatments that included triplicate groups of feeding ratio in 5% decrement were prepared for this study: 100% (satiation), 95%, 90%, 85%, 80%, 75% and 70% of satiation. Fish in the control group were hand-fed to apparent satiation twice a day. Then feed allowance in the rest of the six groups was determined based on average feed consumption in the control group. The feeding trial lasted for 7 weeks. Survival was over 97% and was not significantly (P > 0.05) affected by the feeding ratios. Weight gain and SGR of fish fed to 100% of satiation were not significantly different from those fed to 95% of satiation but significantly (P < 0.05) higher than those of fish fed to 90%, 85%, 80%, 75% and 70% of satiation. Weight gain, SGR and feed consumption of flounder linearly (P < 0.001) decreased with a decrease in feeding ratio. However, feed efficiency ratio, protein efficiency ratio and protein retention in fish body were not significantly (P > 0.05) affected by the feeding ratio. The crude protein levels of the whole body without liver or liver were significantly affected by the feeding ratio. Hepatosomatic index and condition factor of fish were not significantly (P > 0.05) affected by the feeding ratio. It can be concluded that optimum feeding ratio for growth of juvenile olive flounder could be lowered to 95% of satiation without growth suppression.  相似文献
