ABSTRACT
Objective To observe the sensitivity of Wuzhishan, Tibetan and Bama minipigs to exogenous fats.Methods A total of 15 male minipigs including 5 WZS minipigs, 5 Tibetan minipigs and 5 Bama minipigs, were used in this study.The minipigs were intravenously injected with fat emulsion and fed with high-fat diet, and the changes of serum total cholesterol (TC), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) and triglyceride (TG) levels were detected at 0.5 h, 1 h, 1.5 h, 2 h, 2.5 h and 3 h after intravenous injection of fat emulsion and at 3 h and 12 h, 24 h, 36 h, 48 h, 60 h, 72 h and 84 h after fed with high-fat diet, respectively, and calculated the changes of area under the curve (ΔAUC) values.Results The triglyceride (TG) in the three kinds minipigs were significantly increased (P Wuzhishan minipig > Bama minipig, while TC, LDL-C and HDL-C showed no significant changes (P>0.05).Moreover, TC, LDL-C, HDL-C and TG were significantly increased in the three stocks of minipigs induced by feeding with high-fat diet (P Bama minipigs > Tibetan minipigs.Conclusions The three stocks of minipigs are sensitive to TG after intravenous injection of fat emulsion, and the lipid tolerance values are in an order of Tibetan minipig > Wuzhishan minipigs > Bama minipigs.Meanwhile, the three stocks of minipigs are also sensitive to TC, LDL-C and HDL-C after feeding with high-fat diet, and the lipid tolerance values are in an increasing order of Wuzhishan minipig > Bama minipigs > Tibetan minipigs.
