Question

4. What is meant by the following terms?
(1) Rearing (ii) Shearing (iii) Sericulture​

Answer 1

Answer:

1. The rearing of animals is defined as animals raised or bred for their use, or for pleasure or for profit, often for food. These activities have associated common problems of odor and elimination of animal waste.

2. Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.

3. Sericulture is the process of cultivating silkworms and extracting silk from them. The caterpillars of the domestic silkmoth (also called 'Bombyx mori') are the most commonly used silkworm species in sericulture.
