Influence of farm application of oregano on performances of sows.
This study was performed in a large commercial herd in eastern Europe to test the effect of oregano feed supplementation. Sows were studied in a unit where alternate farrowing groups were given diets containing 1000 ppm oregano in the prefarrowing and lactation diet. Oregano-treated groups showed a lower (P = 0.003) annual sow mortality rate, a lower (P = 0.03) sow culling rate during lactation, an increased (P = 0.01) subsequent farrowing rate, and more (P = 0.05) live-born piglets per litter compared with the nontreated sows. The conclusion was that dietary oregano supplementation improved the reproductive performance of sows in this herd.
