Abstract：A total of 387 meat samples from 8 livestock species collected from grasslands, semi-agricultural and semipastoral areas and outskirt breeding bases in Inner Mongolia were analyzed for cholesterol contents. The overall average of cholesterol content of silverside and rib from each species was estimated and differences between species and anatomical parts, as well as cattle and sheep of different genders slaughtered in different seasons at different ages were examined. Results showed that the cholesterol content of meat from 8 animal species was in the descending order: goat (69.60 ± 12.73) mg/100 g, sheep (54.77 ± 10.96) mg/100 g, pork (52.72 ± 6.19) mg/100 g, cattle (49.98 ± 12.31) mg/100 g, donkey (47.88 ± 15.08) mg/100 g, deer (43.63 ± 4.37) mg/100 g, camel (41.57 ± 8.62) mg/100 g, and horse (41.17 ± 14.83) mg/100 g, indicating that goat meat showed a significantly higher cholesterol content than meat from other animals and camel meat and horsemeat had a significantly lower cholesterol content than meat from other animals. The cholesterol content of meat of cattle slaughtered in winter was significantly lower than in summer and autumn; however, the opposite result was observed for mutton without significant difference. An increase in cholesterol content was found for bull meat compared with cow meat and castrated bull meat, but showing a significant difference from castrated bull meat. Ewe meat exhibited a significant increase in cholesterol content than the meat of ram and castrated sheep. The cholesterol content of both beef and sheep meat displayed an apparent upward trend with increasing slaughter age.
