Answer: Option B

Solution(By Examveda Team)

Length of dry period in well-fed cows should be 40 - 80 days.
Dry period includes the time between halting of milk removal (milk stasis) and the subsequent calving.
A dry period of at least 60 days is the most economical and optimum for health, fertility and milk production. Dairy cows that are dry for fewer than 40 days will have a reduced milk output of at least 250 kgs milk in the following lactation.
