The amount of milk produced per day during this period varies considerably by breed and by individual cow depending on her body condition, genetics, health, and nutrition. [10] During this period the body condition of the cow will suffer because the cow will draw on her body stores to maintain such high milk production.

This part of their lactation cycle is referred to as the cows dry period and typically last between 40 and 65 days. [1]

This is an immunologically mediated adverse reaction, rarely fatal, to one or more cow's milk proteins. [119] Milk allergy affects between 2% and 3% of babies and young children. [120] To reduce risk, recommendations are that babies should be exclusively breastfed for at least four months, preferably six months, before introducing cow's milk. [121]
