Late gestation
As from 28 days pre-partum, foetuses start growing, and as from 21 days pre-partum the udder starts preparing for lactation, laying the basis for good colostrum production. Experience shows that increasing the amount of feed, to a level around 3.5 kg/sow/day, for the last 28 days pre-farrowing assures sufficient nutrients for the growth of the foetuses to achieve the desired birth weight.
