[Objective] The study was to provide the theoretical basis for the protection, breeding and rational utilization of Bamei pigs. [Method] 12 Bamei pigs from Qinghai were taken for fattening experiment, and 6 pigs from which were slaughtered at the end of the fattening experiment to determine ketone body and meat performances, and the determinationResults were compared with those of other breeds at home and abroad. [Result] In fattening period, the average daily gain of Bamei pigs was 409.86 g, being lower than that of duroc, Rongchang and Min pigs. Their dressing percentage was 70. 19% , being equivalent with that of most breeds. Their average fat thickness was 3. 38 cm, being thiner than that of Erhualian and Min pigs. The pH value of their muscle was 6.43, being equivalent with that of local breeds. Their meat color and marbling were all given 3-4 score (1-5 grade scoring system) , being lower than that of Min and Neijiang pigs. Their water loss rate was 18.86% , being lower than that of duroc pigs. Their cooked meat percentage was 66. 12% , being lower than that of Neijiang pigs, and higher than that of Min, Erhualian and duroc pigs. Their muscle fat content(7. 16% ) was higher than that of other breeds. [Conclusion] Breed protection and selection for Bamei pigs from Qinghai should be continue.
