1 2012 North Dakota FFA Convention Pedigree Evaluation [50 points] Given the following scenario, place the attached four (4) pedigrees in the order best suited to meet the long term goals of the purebred Holstein farm described in the following scenario. Scenario Browning Felbaum and Sons Dairy is a smaller family run dairy farm with interests in showing cattle at exhibition. They are planning to purchase some embryos to add to their genetics at an upcoming auction. After studying the sale catalog they have narrowed their choices to the embryos from the following four cows. All of the cows are bred to the same sire, Comestar Lee. It is important to their long range breeding plan that they do not increase the inherent inbreeding coefficient with the addition of these embryos. Furthermore they have defined a need to increase the longevity of the cows in their herd, which includes emphasis on feet and legs, and udder composite score, with special attention to the type production index. If the price to be paid is the same for the purchase of any of the embryos from these four cows, how would you rank the selection of these cows from which they would purchase embryos? Rank the cow pedigrees below according to the attached provided numbers ( ): Placing: 1 st 2 nd 3 rd 4 th Filename: 1a PedigreeQUIZ_2012 Page 1 of 1

Scenario Browning Felbaum and Sons Dairy is a smaller family run dairy farm with interests in showing cattle at exhibition.

After studying the sale catalog they have narrowed their choices to the embryos from the following four cows. All of the cows are bred to the same sire, Comestar Lee.

If the price to be paid is the same for the purchase of any of the embryos from these four cows, how would you rank the selection of these cows from which they would purchase embryos? Rank the cow pedigrees below according to the attached provided numbers ( ): Placing: _1 _2 _4 _3_ 1 st 2 nd 3 rd 4 th Cuts: Reasons: In a reasonably close top pair, 1 places over 2 because she scores higher in the preferred selection categories of feet and leg composite, udder composite score, and has the highest total performance index (TPI) in this class. In the middle pair, 2 not only had a higher classification score, but handily placed over 4 because she possesses a substantially more desirable feet and leg score, as well as udder composite, and TPI. In the bottom pair, I grant the higher classifying 3 cow shows more genetic potential until you acknowledge she is a descendant of Comestar Lee and would further contribute to the herd manager s concern about inbreeding. Cow 3 is the least desirable choice in this scenario. Despite her higher TPI score she does not meet the minimum selection requirement to avoid further inbreeding.
