The Effect of Feeding Different Parts of Adipose Tissue of Buffalo on the Health of Golden Hamsters
This study aimed to investigate the effects of feeding buffalo sternum subcutaneous adipose tissue(SSAT,with high unsaturated fatty acids content)and perirenal adipose tissue(PRAT,rich in saturated fatty acids)on the health of golden hamsters.SSAT and PRAT from 24-month-old Mora buffalo were used.Thirty 6-week-old female golden hamsters were randomly divided into three groups:a normal diet group(ND group,10%fat),an SSAT high-fat diet group(HFD-SSAT group,45%fat),and a PRAT high-fat diet group(HFD-PRAT group,45%fat).After a 1-week adaptation period,the experiment lasted for 8 weeks.Blood samples were collected in weeks 0,4,and 8.Liver and inguinal adipose tissue were collected at the end of feeding.During the experiment,body weight was measured weekly and food intake was measured daily.The results showed that compared to the ND group,the final body weight,average daily weight gain,Lee's index,blood lipid concentration(triglycerides,choles-terol,etc.),body fat deposition,liver injury,and lipid metabolism of golden hamsters in HFD-PRAT group were significantly increased(P<0.05 or P<0.01),indicating that high-fat feeding can cause obesity in golden ham-sters.Under the high-fat feeding,the final body weight,average daily gain,Lee's index,blood lipid concentration(cholesterol,arteriosclerosis index,etc.),body fat deposition,liver injury,and lipid metabolism of golden hamsters in HFD-SSAT group were significantly lower than those in HFD-PRAT group(P<0.05 or P<0.01).In sum-mary,buffalo SSAT,which is rich in unsaturated fatty acids,can alleviate the health risks brought by high-fat feed-ing.These results provide important basic information and materials for the regulation of unsaturated fatty acid pro-duction in buffalo.
