Solution
The correct option is A Artificial insemination
The given question is about Ramu’s high yielding cow, which is not ready to receive the male nowadays during the oestrus cycle. It may be due to various reasons like hormonal changes, pain in the reproductive tract etc. The reproductive cycle in cows is called the oestrus (heat) cycle, during this period the gametes will be available for fertilisation. If the cow didn’t receive the male in the oestrus cycle then it will result in loss for the farmer, as mating helps in pregnancy and after delivering the calf the production of milk increases.
Natural breeding refers to the random mating that occurs between two individuals of the same species in nature.This will not be possible in this particular case, as the cow is not ready to receive the male. So option b is wrong.
Out-breeding is the practice of breeding unrelated animals. Out-crossing and interspecific hybridisation are types of out-breeding. Out-crossing is the practice of mating animals within the same breed which do not have common ancestors on either side of their pedigree upto 4-6 generations. So option c is wrong.
Interspecific hybridisation is the practice of mating of male and female animals of two different species. So option d is wrong.
So the best way to tackle this problem is to follow artificial insemination. In this method, the semen of a superior male is collected and injected into the reproductive tract of the selected female. This will help in overcoming the problems related to normal mating like the cow is not ready to receive the male. The success rate in natural mating is fairly low, so artificial insemination increases the chances of fertilisation. Hence option a is the correct answer.
