Suppose you need to choose one among four available young sires to be used on your herd. Sires 1 and 2 were raised on farm A, and presented phenotypic values (own performance) of 140 and 130 units, respectively. Sires 3 and 4, raised on farm B, presented phenotypic values of 180 and 175 units, respectively. If this was all the information available to you, which sire would you choose? Justify. If it is known that animals raised on farm B present on average 50 units more than similar animals raised on farm A, would you change your choice? Which sire would you pick then? Justify. Now suppose you need to choose between Sire 2 and Sire 3, and that there are two additional pieces of information available. First, none of the sires have any apparent genetic defect. Second, Sire 2 has a much higher inbreeding coefficient than Sire 3. Which sire would you choose to use as breeding stock? Justify.

Solution

a)I Will choose the sire 3,because it is expected to have more performance as heaving highest phenotypic value. b)sire no 3 Will be the choice as it is having highest phenotypic value. c)out of sire2 and sire 3 sire3 will be the choice because sire 2 has higher inbreeding coefficient. Because inbreeding reduces performance. It will increase genetic disorder.
