In recent years, disorder in lipid metabolism has been increased markedly in companion animal’s population. Hyperlipidemia is a common sign of obesity in dogs, which is characterized by hypercholesterolemia or hypertriglycemia. The purpose of the present survey is to determine the effect of obesity on blood lipid profile changes (including triglyceride, total cholesterol, HDL-C and LDL-C) and comparing the decisive indicators of obesity in dogs in Ahvaz district. Three groups of thirty dogs referred to Veterinary Hospital of Ahvaz were studied between 2012-2014. The dogs in group A (control), had good body condition score (BCS= 4 to 5). The dogs were all thin (BCS= 1 to 3) in group B, and all obese in group C (BCS= 6 to 9). All of the studied dogs were selected from small breeds (Terrier, Spitz, Pekingese and Shih Tzu), of both sexes and ranging from 1 to 7 years old. Fasting blood samples were collected from all dogs and lipid profiles including serum triglycerides, total cholesterol, HDL and LDL were measured using commercial kits. Hyperlipidemia was confirmed in dogs of group A (normal) in 4 cases (13.33%), group B (thin) one case (3.33%), and group C (obese) in 19 cases (63.33%). Data analysis showed that there was a significant difference between group C (224.83±74.34) with groups A (149±39.66) and B (131.80±24.37) for triglyceride level (p<0.001), as well a significant difference was seen between group C (229.40±60.36) with groups A (178.80±50.17) and B (151.47±23.45) and between group A with B for cholesterol level (p<0.05). The difference was significant for LDL-C between group C (67.10±22.83) with groups A (47.97±13.01) and B (43.07±13.08) (p<0.001), but there was no difference between various groups for HDL-C (p>0.05). The effects of age, gender and breed on the measured values did not show a significant difference between three groups (p>0.05). The present survey showed that there was a correlation between obesity and hyperlipidemia in dogs. Determination of body condition score (BCS) can be as a predictive agent in characterization of lipid profile status. Modification of diet and weight loss is necessary in obese dogs.

BACGROUND: Traditional medicine can be considered as a method to reduce dietary obesity. OBJECTIVS: The aim of the present study was to assess the protective effect of Iranian green and black tea on diet induced obesity. Twenty four male Wistar rats (180±20 g) were divided into four groups. Control group was fed with rat regular diet (4% fat), and the three reminder groups were fed by high fat diet (25% fat). While control (C) and a high fat group (HF) had ad libitum access to water, the rest high fat groups had free access to drinking black tea (HF+BT) or green tea (HF+GT) instead of water. Eight week later rats were euthanized, weighed and their abdominal fat and organs separated and weighed. While Feed intake showed significant decrease in HF group compared with the control group (99.25±12.03 vs. 113.59±14.40 g/day; p<0.05), the levels of energy intake (454.54±55.09 vs. 405.52±51.43 kcal/day; p<0.05) and weight showed increase (283.33±13.84 vs. 223.33± 15.11g; p<0.05). Green and black tea made decrease in body weight gain compared to the HF group (71.67±1.61g and 57±12.95 vs. 104.33±21.75 g; p<0.05). However, the abdominal fat was just lower in HF+BT group than the HF group (2.90±0.56 vs. 4.19+.77g; p<0.05). Consumption of Iranian black and green tea may help to regulate body weight and reduce weight gain induced by high caloric food.
