Question

An appropriate example of ‘weeding’ is

• A. Docking
• B. Castration
• C. Dehorning
• D. Debudding

Hint:

Weeding = Removing poor genetic material from the breeding population.
Castration is the most common management tool used to weed out scrub bulls, rams, and boars.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In livestock breeding and herd management, "weeding" (or culling) refers to the identification and removal of undesirable, unproductive, or genetically inferior animals from the breeding pool.
This practice helps improve the average genetic merit and performance of the herd over time.

Step 2: Detailed Explanation:
Weeding can be accomplished by physically selling/slaughtering inferior animals or by removing their ability to reproduce.
Castration is the removal or inactivation of the testes in male animals.
By castrating genetically inferior, diseased, or scrub males, managers prevent them from breeding with females in the herd.
This acts as an effective form of selective weeding.
Docking is the removal of a portion of the tail, typically in sheep, to improve hygiene and prevent fly strike.
Dehorning and debudding are management practices used to remove horns or horn buds to prevent injuries among herd members and handlers.

Step 3: Final Answer:
Castration is an example of a weeding practice because it prevents genetically inferior males from reproducing.
