Sumario:Newborn piglets have small energy reserves consisting of fat and glycogen, most of which are deposited in the liver and muscle tissues and therefore not available for thermoregulation. Hence, it is of utmost importance for the piglet's survival that it receives nourishment (colostrum) from the sow as soon as possible after birth to cover the piglet’s survival needs and enable a healthy increase in body weight. The composition of the sow’s colostrum changes a lot within the first day after farrowing. How can one improve the sow's colostrum to get the optimal amount and composition? This is a literature study aimed at investigating whether the age and feeding of the sow affects the quantity and composition of the produced colostrum. The literature shows that the feeding of the sow has a significant effect on the composition of the colostrum, and also that the age of the sow has a significant impact on the duration of the farrowing, which in turn has a significant association with the produced colostrum quantity. Something that also emerged during the study was that the genotype of the sow has a significant impact on the colostrum composition.
