There are 50 well‐defined breeds of Bos indicus origin. Genetic improvement in indicine breeds would improve economic output to farmers and thereby support the conservation of B. indicus breeds. Most of the current breeding programs in Indian dairy cattle are based on phenotypic records of an individual animal or pedigree‐based selection of breeding bulls based on performance recording of elite cows. However, the accuracy of selection remains low due to a limited number of animals under the study and inaccurate pedigree records ultimately resulting in slow genetic response to selection. In addition to this, a long generation interval of B. indicus animals mainly due to high age at maturity which increases the genetic gain and reduces the response to selection. To overcome these limitations and fairly increase the rate of genetic gain, the genomic selection could be the preferred method in animal breeding.EnglishThesis
