Answer: Option B
Solution:
The heat period for cows is 18 - 24 h.The time when a cow is on heat is defined as the period during which a cow will stand to be ridden by her herd mates or a bull. It occurs every 18 - 24 days, averaging 21 days in non-pregnant cows and lasts on average 14 - 15 hours.
The cattle come in the heat after every 21 days of the estrous cycle, but it may occur anywhere between 18 to 24 days. The standing heat lasts for a duration ranging from 6 - 30 hours, with an average duration of 15 - 18 hours.
