Abstract
Inbreeding has negative effects on various pig traits, of which litter size, survival and weight traits are of considerable interest to researchers because they have high economic importance and affect the survival of the related pig population. These traits are complexly influenced by many interacting biological, nutritional, management and environmental factors. Studying the physiological mechanism of the effects of these factors including inbreeding depression on these traits may help prevent or reduce the caused economic loss. This review briefly summarises the physiological mechanisms affecting litter size, piglets born alive/dead and birth weight with an emphasis on genetic and biological factors. In addition, studies detecting genes, or quantitative trait loci that affect the traits mentioned, are also discussed.
