[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

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
