Nutrient requirement for prenancy and lactation
|
/font>
-
Pregnancy requirements are relevant to last 6 weeks of pregnancy and lactation requirements are relevant to first 2 months of the lactation.
-
During the third month of lactation, the prescribed requirements could be reduced by 25%.
-
The lactation requirements during the first 2 months are approximately twice the requirements for maintenance at the corresponding body weight.
