Boars Live Longer in Top Herds
JAPAN - Koketsu and Sasaki have published a study into boar culling and mortality in commercial herds. On average, they found that boars were culled or died aged two years and eight months, having been in the breeding herd for just over two years and one month. Boars in high-performing herds entered the breeding herd earlier and were retained longer than in average herds.
