[ Method ] In terms of differences in sensory state and physical and chemical indicators of hams produced by fragrance pigs with different weights, 29 fragrance pigs at five weight grades were chosen and processed in accordance with Chinese ham processing methods. The products were evaluated by sense, and their salt and moisture contents were also measured. [Result] The fragTance pigs less than 30 kg were not suitable for making Chinese ham, while the fragrance pigs weighed 32 -45 kg could be made into the ham with prominent flavor, beautiful appearance, good color, moderate taste, and suitable moisture content, of which the pigs weighed 40 -45 kg were the best materials for processing small ham. [ Conclusion] The study provided scientific basis for industrial development of fragrance pig.展开更多

The internal organs of Congjiang fragrance pig and Huanjiang fragrance pig with different month ages were weighed. The results showed that the proportion of stomach in body weight in Congjiang fragrance pig was higher than that in Min pig,Harbin white and Landrace,and the proportion of large intestine in body weight in Congjiang fragrance pig was also higher than that in ordinary pigs; the weights of heart,liver and kidney in 8- 10 months old Congjiang fragrance pig were similar to that in Chinese adults. This provided reference data for future in-depth development and utilization of fragrance pig.展开更多

[Method]The growth development and reproductive performance of 100 pigs from six towns in central fragrance pig producing area and Congjiang fragrance pig stock seed farm were measured,and further compared with the data in Guizhou Livestock and Poultry Breeds 1986. [Result]The growth and development status was basically consistent,and the average litter size was at a downward trend: the first litter decreased by 26. 2%; the second litter decreased by 7. 0%; the third litter decreased by8. 55%. [Conclusion] The study laid the foundation for vigorous promotion of Congjiang fragrance pig in industrial development process,acceleration of breeding pace,gradual updating of farming breeds by farmers and improvement of production efficiency of fragrance pig.展开更多

[ Method ] Using 27 pairs of micmsatellite loci jointly recommended by Food and Agricultural Organization （FAO） and International Society for Animal Genetics （ISAG）, we detected the genotypes of 200 fragrance individuals belonging to four types （Jiuyang fragrance pig, Jianbai fragrance pig, Cangjiang fragrance pig and Huangjiang fragrance pig）, and analyzed their inter-and intra-breed genetic variations. Clustering analysis was also conducted using neighbor-joining （NJ） method and unweighted pair-group method with arithmetic mean （UPGMA）. [ Result] The genetic relationship between Congiiang fragrance pig and Huangjiang fragrance pig was the closest, followed by the ge- netic relationship between Jiuyang fragrance pig and Jianbai fragrance pig; the genetic distance between Jianbai fragrance pig and Huangjiang fragrance pig was the farthest, which was consistent with their geographic distribution, ecological environment and body physical characteristics. Clustering resuhs showed that Jiuyang fragrance pig and Jianbai fragrance pig clustered into one class, while Congjiang fragrance pig and Huangjiang fragrance pig clustered into another class. [ Conclu- sion] The study laid the foundation for quantitative trait loci positioning of good genes of these breeds and implementation of genetic marker-assisted selection.展开更多
