NEET Biology Question Bank - Animal Husbandry and Plant Breeding

9 Animal Husbandry and Plant Breeding
Animals and plants are used for food since evolution of man takes place same it primitive. Thousands of
years ago, agriculture began. Today in the animal husbandry; dairy farming, poultry, apiculture, fisheries and in
plant breeding. Various methods of breeding and tissue culture are applied for getting more food to fulfill the
need of increasing human population.
· Animal husbandry :
Animal husbandry is an important from very beginning in development of human beings. It is
important for food production, The dairy industry, covers the production, processing and distribution of
milk. In Gujarat this industry is well developed.

both in terms of quantity and quality has been met by good animal
husbandry practices.
- These practices include (1) management of farm and farm animals and
(2) animal breeding.
- In view of the high nutritive value of honey and its medicinal importance,
there has been remarkable growth in the practice of bee-keeping or
apiculture.
