A) Sahiwal
B) Karan-swiss
C) Tharparkar
D) Jersey

Answer 1

Hint: With the increasing population the requirement for food has also risen across the world. Animals are an important part of agriculture. They are used to derive milk, meat, eggs, wool, silk, labour, etc. As the animals also play an important role in agriculture, they require proper care and management.

Complete answer:
Animal husbandry is defined as the science of caring for and breeding domestic animals and the development of genetic traits such as high yielding, disease resistance, etc. It involves breeding and raising livestock like buffaloes, cows, goats, camels, horses, sheep etc.

Now let us look into the given options:
A) Karan Swiss is a cattle which is a crossbreed and high yielding breed of cow. It is the crossbreed of Brown swiss and Sahiwal.
B) Sahiwal is one of the best exotic breeds which has high heat tolerance and high milk production.
C) Tharparkar is a breed that originates in Tharparkar District. It is a breed that is used for high milk production and known for its draught potential.
D) Jerseys are well known for their milk which is high in quality. It is especially rich in protein, minerals and trace elements and it is also rich in colour which is naturally produced from carotene, an extract from grasses.

So, the correct answer is Option B.

Note:
- Animal breeding is a part of animal husbandry. Breeding of animals aims to develop high yielding animals and improve the desirable qualities of the produce.
- Inbreeding refers to the practice of mating closely related superior males to superior females within the same breed for four to six generations. But continued close inbreeding to inbreeding depression.
- Out-breeding is defined as the breeding of unrelated animals that can be carried out in three different fashions. Out-crossing is when two unrelated individuals of the same breed who do not have a common ancestor for the past four to six generations are mated.

- Mating between a superior male of one breed and a superior female of another breed to give rise to a progeny which has combined qualities of both breeds is known as crossbreeding.
- When males and females across different related species are mated it is known as interspecific hybridization.
