Abstract

The growth performance of suckling pigs is largely dependent on sow’s milk production and nutrient components. Under the current feeding regimen, sows can not produce sufficient milk to sustain the maximal growth of neonatal pigs from the 8th day of lactation. Thus, it is necessary to elucidate the metabolic mechanisms regarding milk precursor uptake and milk component secretion. In this paper, uptake of glucose, fatty acids, amino acids, minerals and vitamins, secretion of milk components and potential mechanisms regarding the process of uptake-secretion were discussed.

Key words： lactation; sows; mammary gland; milk precursors; milk secretion
