Abstract
The objective of this study was to estimate the genetic parameters of sow lifetime productivity and lifetime non-productive days. Purebred sows, 507 of Landrace (LR), 97 of Yorkshire (YS), and 11 of Duroc (DR) respectively, were selected as 615 sows (2,589 records). They were from entry in 2016 to removal in 2019. The traits in this study were classified as sow-level and parity-level. The sow-level consisted of the lifetime non-productive days (LNPD), annualized lifetime non-productive days (ALNPD), lifetime weaned-to-first service interval (LWSI), annualized lifetime weaned-to-first service interval (ALWSI), lifetime productive days (LPD), annualized lifetime productive days (ALPD), lifetime gestation length (LGL), annualized lifetime gestation length (ALGL), lifetime lactation length (LLT), annualized lifetime lactation length (ALLT), lifetime total born (LTB), annualized lifetime total born (ALTB), lifetime pig born alive (LBA), annualized lifetime pig born alive (ALBA), lifetime pig weaned (LPW) and annualized lifetime pig weaned (ALPW), while parity-level had traits of NPD, WSI, TB, BA, and PW in each parity. Multivariate animal models were used to estimate genetic parameters as heritability (h2), genetic correlation (rg), and phenotypic correlation (rp) of traits. The results showed that the LR sows have the highest lifetime productivity with the lowest in LNPD. The DR sows were able to retain in the herd for the longer time with higher LNPD and lower lifetime productivity than other breed sows. The h2 estimation of LTB, LBA and LPW were low, ranged from 0 to 0.04, while h2 of the LNPD and LWSI were ranged from 0.10 to 0.19. The rg among LTB vs LBA, LTB vs LPW and LBA vs LPW were estimated by 0.99, 0.89, and 0.92, respectively. The rg between LNPD and LWSI was estimated by 0.81. This study indicates that the genetic effect on LNPD, LWSI, LTB, LBA, and LPW traits is relatively low.
