Which of the following is the best breeding method for animals which are below average in productivity in milk production?
Out-crossing is the breeding method in which there is mating of animals within the same breed, but having no common ancestors on either side of their pedigree. The offspring obtained are called out-cross.
This is one of the best breeding methods for animals which show low milk production.
In a cross-breeding method, superior males of one breed are mated with superior females of another breed. Cross-breeding allows the desirable qualities of two different breeds to be combined.
Example: Bikaneri sheep of India are famous for their brilliant white fleece whereas Marino sheep of Australia are well known for their soft and bulky wool.
In Punjab, Bikaneri ewes were crossed with Marino rams to give rise to a new breed called Hisardale. Hisardale produced white wool in higher quantities.
In interspecific hybridisation, male and female animals of two different related species are mated. Example: Mule.
On the other hand, mating of very closely related animals within the same breed is called inbreeding.
