8.1 Difference between dry cows and lactating cows
Dry cows and lactating cows are at different stages in their milk production cycle:
Dry cows are cows that are not currently producing milk. They are in a resting
phase before they start lactating again. This period is important because it allows
their udders to recover and prepare for the next lactation cycle.
Lactating cows, on the other hand, are actively producing milk. These cows
require a higher amount of nutrients, especially energy and protein, to support
milk production.
