Which of the following are advantages of natural breeding?
I. Reduction of effort of breeders and ease of mating between males and female with superior characters.
II. Semen collected from the superior males can be preseved and used later.
III. There are less chances of spreading of contagious diseases.
IV. It does not involve heavy expenditure on laboratories, equipments or expert personnel.

The correct option is D I and IV
Animal breeding is an important aspect of animal husbandry (rearing, caring and breeding of animals for products like meat, milk etc.). It involves controlled mating of domesticated animals to obtain offspring with superior genotypes.
Animal breeding can be done my natural methods or by artificial methods. In natural breeding the animals with the desirable characteristics are allowed to mate by natural means.
Major advantages of natural breeding are as follows:
- It requires minimum effort from the breeders. Mating can be ensured by placing the superior males together with the selected females in an enclosed space. So statement I is correct.
- It does not involve the use of scientific techniques to mate the animals.
- Heavy expenditure on laboratories, equipments or expert personell for carrying out the mating process is not involved. So statement IV is correct.
- Prior collection of semen is not required.
However, natural breeding involves sexual contact between the animals. Thus the chances of spreading of contagious diseases are quite high. So statement III is false.
Semen are collected from superior males and stored for fertilisation in artificial breeding technique like artificial insemination and Multiple Embryo Transfer Technology. A major advantage of artificial insemination is that the collected semen can be preserved at extremely low temperatures to be used in future. Hence statement II is false.
