Besides breeding, nutrition and management aspects, there are many methods developed to achieve those goals in relatively short time. The aids from exogenous promoters are very common in some developed and developing countries: such as porcine somatotropin, beta receptor agonist, and gonadotrophin-releasing factor vaccine have been used to increase growth performance in commercial pigs; several exogenous gonadotropin have been regularly used in controlling sow reproductive performance, such as oxytocin, progesterone, PGF2α、PMSG (or eCG)、hCG, etc. But, adding those exogenous additives might interrupt animal breeders in their decisions of selecting superior animals based on the production performance and breeding value. Such interruption might cause mistakes in the selection production in a herd as well as national breeding system. Thus, our study is going to investigate adding exogenous promoters into feeds of pigs would cause certain positive and/or negative effects to animals and consumers, and the influence of these promoters on the swine genetic improvement program.外源性促進劑生長繁殖表現調控豬隻Exogenous promoterRegulations of growth and reproductive performancePigs
