Question

How much maximum time a normal newly born calf takes to get up on his/ her legs

• A. 15 minutes approx.
• B. 30 minutes approx.
• C. 45 minutes approx.
• D. 60 minutes approx.

Hint:

A healthy newborn calf should stand within 1 hour of birth and consume colostrum within the first 2 hours. Early colostrum intake is vital because the calf's intestinal permeability to protective antibodies (immunoglobulins) drops rapidly after birth.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
After birth, a newborn calf must quickly stand up and find the mother's udder to suckle colostrum, which is critical for obtaining passive immunity. The time it takes for a calf to stand is a key indicator of its vigor and vitality.

Step 2: Detailed Explanation:
Let us analyze the normal behavioral milestones of a healthy newborn calf:

Immediately after birth, the mother licks the calf to dry its coat, stimulate blood circulation, and encourage respiration.

Within the first 15 to 30 minutes, a healthy, vigorous calf will make its first attempts to rise, sitting in a sternal recumbent position.

Due to wet hooves and uncoordinated motor control, the calf will slip and fall several times.

Under normal conditions, a healthy calf will successfully stand on all four legs within45 to 60 minutes (approximately 1 hour) after birth.

If a calf fails to stand up after 2 hours (120 minutes), it is considered weak or suffering from dystocia (difficult birth), requiring immediate veterinary assistance and manual colostrum feeding.

Therefore, 60 minutes is the accepted maximum normal time for a calf to stand.

Step 3: Final Answer:
The correct option is (D), representing 60 minutes approx.
