Litter sizes in business pig manufacturing have elevated considerably over latest years; nevertheless, farrowing pen sizes have usually not modified over the identical time interval. The target of this examine was to guage the impact of farrowing pen measurement on piglet pre-weaning development and mortality. Variations in pen measurement had been created by various the width of pens of the identical size, rising the creep space obtainable to the piglets. The examine used a complete of 1,786 litters in a randomized full block design to check two farrowing pen measurement therapies (FPS): Normal (pen width 1.52 m) and Elevated (pen width 1.68 m). Litter sizes had been equalized throughout therapies (12.9 ± 1.95 piglets) at 24 h after start utilizing cross-fostering. Litter weights had been collected at start and weaning (21.3 ± 2.08 d); pre-weaning mortality was recorded. The experimental unit was the litter; fashions for statistical evaluation included farrowing pen measurement and replicate.
Farrowing pen measurement had no impact on litter measurement at start (12.8 and 13.0 for the Normal and Elevated farrowing pen measurement, respectively), after cross-fostering (12.9 for each therapies), or at weaning (11.2 and 11.3, respectively). There was no impact of farrowing pen measurement on whole litter or common piglet weight at start, after cross-fostering, and at weaning.
These outcomes counsel no profit in piglet efficiency from rising the width of farrowing pens. As litter sizes proceed to extend in business manufacturing, additional analysis is warranted to re-evaluate the influence of farrowing pen measurement on pre-weaning mortality.
