Question

How are the cattle useful in the production of leather, biogas, fertilizer and gelatin?

Answer 1

The role of cattle in leather industry, biogas production and gelatin industry :

1. Leather industry : Cattle and buffalo skin is the principal source of leather supply. The skin of cow is called kips and that of the buffalo is known as buff.

In tannaries, the raw skin obtained from animals is processed following various steps such as flaying, curing, salting and tanning.

2. Biogas : In the production of biogas, the cattle dung, urine and some of the agricultural wastes are put into huge tanks built for this purpose along with some quantity of water. Bacteria normally present in these wastes bring about putrefaction and release the gas which can be supplied through pipes. The biogas can be used as a cooking fuel and it also can be used for the purpose of lighting.

3. Gelatin : In cattle, many parts of the body contain collagen which can be used for the produc­tion of gelatin. There are a number of uses for gelatin in food and chemi­cal industries.
