Rearing and Breeding of Sheep
NCERT Exemplar Class 7 Science Exemplar Chapter 3 problems talk about the processing of fibre and all the steps that are involved in it. In this chapter, you will learn that the very first step in the production of wool is rearing and breeding of sheep. Sheep are taken to graze in the fields and are kept indoors and taken care of. With proper care of the sheep they grow well and a thick layer of hair also grows on their body. This layer yields a good quality of wool in large quantities.
After hair is obtained from the sheep, the first step of processing fibre from the wool consists of shearing. In this process, the fleece of sheep is removed from its body along with a very thin layer of its skin. This process is carried out during warm weathers to ensure that the sheep are able to cope with the temperature and survive. There are many other steps which are involved in this process like scouring, rolling etc. in this chapter you will learn about all of these in a detailed manner.

In this chapter, you will learn about silkworms and how they are the producers of this fine silk. Silk fibres also fall in the category of animal fibres. The silkworms spin silk fibres and the process in which these silkworms are reared for obtaining silk is termed as Sericulture.
