Managing prolific sows in tropical environments

Padet Tummaruk, Fabio De Rensis, Roy N. Kirkwood

Molecular Reproduction and Development > 90 > 7 > 533 - 545

Litter size in modern sows has been dramatically improved in recent decades by genetic selection for highly prolific sows. In a tropical environment, the average total number of pigs born and number born alive are reported to be as high as 17.2 and 15.1 piglets per litter, respectively. Therefore, the new production target in many herds aims to achieve 30–40 pigs weaned per sow per year. Despite the...
