  2. 族群大小 種豬： 7公,38母 候補女豬：23頭

  3. 基因多樣性

  4. 基因庫 2007 • Polymorphism of the mitochondrial DNA control region sequence was used to clarify phylogenetic relationships among two herds of Lanyu pigs(NTU, TAPS). • Two distinct mitochondrial control region haplotypes were found. • The type I Lanyu sequence appeared independently as a unique clade different from Asian and European pig sequences. • The type II Lanyu sequence was clustered within the major Asian clade.

  5. Conservation & Population management • Population management • Dividing into groups according to genetic distance and conserving both haplotypes. • Mating system application for maintaining genetic diversity.

  6. 細胞庫 • Gametes Cryopreservation • Semen cryopreservation 7 boars , total: 95 straws Sow：0497-05 Boar：0052-02 AI date：2009/ 8 / 4 ~ 6 (5 times) Birth date：2009 / 11 / 28 Total born：11 Born alive：10
