Question

Given below are two statements:
Statement I: Cattle have a visual field in excess of 300 degrees
Statement II: Animal handlers should never work on the edge of light zone
In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is correct but Statement II is false
• D. Statement I is incorrect but Statement II is true

Hint:

Cattle Handling (Temple Grandin): Cattle have $> 300^\circ$ panoramic vision, a blind spot directly behind them, and baulk at sharp light-shadow edges.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Low-stress livestock handling principles (Temple Grandin): prey animal lateral panoramic visual fields and behavioral aversion to sharp lighting contrasts/shadows.
Key Formula or Approach:
\[ \text{Bovine Panoramic Visual Field} = 330^\circ - 360^\circ \quad (\text{Blind Spot directly behind the tail } \approx 30^\circ) \]

Step 2: Detailed Explanation:
In animal behavior, sensory ethology, and livestock handling:
1. Statement I: As prey animals, cattle have laterally positioned eyes with horizontal slit pupils, providing an expansive panoramic visual field in excess of 300 degrees ($330^\circ - 360^\circ$), with only a narrow blind spot directly behind their tail. Hence, Statement I is true.
2. Statement II: Cattle have poor depth perception and dichromatic vision, making them baulk, stop, and refuse to move when encountering harsh shadows, sharp transitions, or glare on the edge of a light-dark zone. Skilled handlers utilize uniform diffused lighting and avoid standing/working at light-dark boundaries to ensure smooth forward movement. Hence, Statement II is true.

Step 3: Final Answer:
Therefore, Both Statement I and Statement II are true, corresponding to option (A).
