This question was posed to me in a national level competition.

I would like to ask this question from Cattle Health in chapter Cattle Health of Dairy Engineering

Answer 1

Correct answer is (c) Between 40 to 50 days

The explanation: The main advantage of scanning is that it can give an accurate diagnosis earlier than rectal palpation. Pregnancy can be detected earlier with ultrasound compared with rectal palpation. 10 to 16% of cows diagnosed pregnant at 40-50 days.
