Abstract

The use of genomic information to aid in the calculation of breeding values is something that has developed quickly in the last decade and will continue to progress in the near future. With the advent of estimated breeding values incorporating genomic information and continuing advancements in the area it is difficult to keep up to date with progress, let alone understand the calculations and science behind the tool that helps farmers make so many crucial decisions with their herd. This paper will give a concise overview of the methods used to calculate estimated breeding values (EBV) and how genomic evaluations are being incorporated within them. Furthermore, it will discuss briefly some possible applications and benefits of this technology with particular attention to the Australian dairy industry and its progress so far with the uptake of this new tool for selection. Lastly, this paper will give a realistic picture on the applications of genomic selection in developing dairy herds and dairy sectors using Pakistan as a case study. Although breed improvement programs are being implemented in the country, the current level of progeny testing and evaluation might restrict the practical use of incorporating genomic selection into breeding values for some time
