Cross-Fostering (CF) is implemented in intensive pig production in order to equalize litter sizes. This management procedure is crucial for reduction of piglet losses during the suckling period, considering the intake of colostrum that is necessary for their proper growth and development. The study aimed to assess the effect of CF and associated factors on the number of piglets alive within seven days of farrowing (PA7d) as the most critical period of their raising. The study was conducted in Croatia from July to mid-November 2016 in the conditions of commercial production and included 316 farrowings in high-fertile hybrid sow lines, LW x L cross-breeds, from 1st to 8th Parity (P) with a total of 3993 Piglets Born Alive (PBA). Piglets were equalized upon completion of the colostrum period. Data analysis was performed using GLM model with six effects included in the model of calculation: PBA, Farrowing Group (FG), Parity Group (PG) with three levels (frst group: primiparous ; second group: secundiparous to quadriparous ; and third group: ≥quintiparous), Average number of Piglets Alive per Group (APAG), CF effect and gender (G) ; the FG*APAG interaction was also observed. Results were expressed as LSM±SE. Signifcant effects were recorded for CF (P=0.04), PG (P |
