Abstract
The study cary out on the growing pig and sow of DVN1 and DVN2 keep in Tam Diep Station for Research and Development nucleus pig breed – Thuy Phuong Pig Research Center, National Institute of Animal Husbandry. The result for sexual materity of growing pig show that: the first eatrus of DVN1 and DVN2 is equal, in tern as 180.87 and 181.17 days of age; the live body weight at first estrus is 127.30 kg for DVN1 and 127.90 kg for DVN2; the first service is 239.73 for DVN1 and 241.03 for DVN2 days of age; the first farrow is 354.87 and 355.90 days of age. Some reproductive capacity characterictics of DVN1 and DVN2 sow is rether high, namely: the piglet per litle is 11.03 of DVN21 and 10.79 of DVN2; the born alive per litle is 10.64 of DVN1 and 10.27 of DVN2; the weaning piglet per litle is 10.13 of DVN1 and 9.80 of DVN2; the weaning weight per litle is 67.10 kg of DVN1 and 65.27 kg of DVN2. Generally, this characterictics of DVN1 and DVN2 also tendentiously increase from first to third farrow.
