Abstract: To analyze the impact of different artificial insemination methods employed by technicians on sow reproductive performance, in order to accumulate technical talents for future artificial insemination training. Additionally, analyze the influence of boar breeds on sow reproductive performance, providing data support for semen selection in pig farms in the future. A total of 1 561 farrowing records from Taiwanese Duroc sows were collected, and single-factor statistical analysis was used to study the influence of artificial insemination technician and sire breeds on sow reproductive performance. The results showed that the effect of different artificial insemination technician on total number born, the litter size, litter weight of birth, dead fetus, number of health litter , number of weaning ,litter weight at 21days, of Duroc sows were significant (P＜0.05). The effect of boar breed on litter weight of birth was significant (P＜0.05), on the other targets were not significant (P＞0.05). The birth weight of piglets produced by sows in the Pietrain boar mating group was significantly 3.58% higher (P＜0.05) than that in the Duroc boar mating group. With the same artificial insemination technician, the effects of boar breed on reproductive performance of sows were inconsistency, the total litter size of the sow herd managed by technician A showed a significant difference (P ＜0.05); the litter weight of piglets birth of the sow herd managed with B artificial insemination technician was significant difference (P＜0.05); the litter weight at 21 days of piglets of the sow herd managed with C artificial insemination technician was significant difference (P＜0.05). The artificial insemination technician significantly influenced the total number of piglets born, number of live piglets, litter weight at birth, number of stillbirths, number of healthy piglets, number of weaned piglets, and litter weight at weaning (21 days) in Duroc sows.The sire breed (Taiwanese Duroc and French-line Pietrain) had no significant effect on the total number of piglets born, number of live piglets, or number of healthy piglets in the Duroc sow population(P＞0.05), but it did significantly affect litter weight at birth(P＜0.05).Among the Duroc sow groups managed by artificial insemination technician A, B, and C, the sire breed showed no significant difference in its impact on the number of live piglets, healthy piglets, or weaned piglets(P＞0.05). The article provided a data basis for the selection of artificial insemination technician and the breed selection of boars in subsequent pig farms.
