Combined effect of sow parity and terminal boar on losses of piglets and pre-weaning growth intensity of piglets

Original language description

This study analysed the effect of sow parity (P), terminal boars (TB), and their combination on reproductive parameters of sows, losses of piglets, and their individual live-weight (LW) and average daily gain (ADG) from birth to weaning. A total of 120 sows of Large White x Landrace hybrid combination from the first to the fourth parity (30 sows per parity) were included in the observation. The sows were inseminated by terminal boars of Pietrain (Pn), Large Whitesireline (LWSL), and Duroc (D) breeds and Duroc x Large Whitesirelinie (D x LWSL), Large Whitesirelinie x Pietrain (LWSL x Pn), and Duroc x Pietrain (D x Pn) hybrid combinations (20 sows per terminal boar population). The results proved a significant effect of P on the total numbers of piglets (TN), the numbers of stillborn piglets (SB), and the pre-weaning losses of piglets (L) (p LESS-THAN OR EQUAL TO 0.01) with the lowest losses found in the third parity sows. A significant effect of TB was confirmed for TN, the numbers of live-born piglets (LB), SB, the numbers of mummified piglets (M) and non-viable piglets (N), and (L) (p LESS-THAN OR EQUAL TO 0.01). The sows inseminated by D and LWSL boars showed the lowest total numbers of piglets but also the highest survivability of piglets until weaning. Significant effects of interaction between P and TB were observed for the TN, SB, N, and L (p LESS-THAN OR EQUAL TO 0.05). Evaluation of growth parameters in piglets (n = 1547) showed that P significantly influenced LW in the first three weeks of life (p LESS-THAN OR EQUAL TO 0.01) and ADG from birth to Day 7 and from Day 15 to Day 21 (p LESS-THAN OR EQUAL TO 0.01). Additionally, a significant effect (p LESS-THAN OR EQUAL TO 0.01) of TB was proven on individual weight and ADG in all the observed time intervals, with the highest growth found in the piglets of the D and LWSL boars. Significant interactions (p LESS-THAN OR EQUAL TO 0.01) between P and TB were found for LW and ADG in all the time intervals.
