6/15/99 Contacts: Looking for Top Dairy Genetics - Here are Iowa's Elite AMES, Iowa -- Dairy expansions in Iowa and other Upper Midwest states have highlighted the ever-increasing need for top quality dairy genetics, said Marjorie Faust, extension dairy specialist at Iowa State University. The Elite Cow and High-Ranking Grade Cow Evaluations are published cooperatively by USDA and the Dairy Herd Improvement Association (USDA-DHIA) to identify superior dairy genetics. The evaluations released recently list 197 Iowa dairy farms accounting for 644 high genetic merit dairy cows. Of these, 556 registered dairy cows from all six dairy breeds were named to the USDA-DHIA Elite Cow List: 10 Ayrshire, 53 Brown Swiss, 22 Guernsey, 430 Holstein, 36 Jersey, three Milking Shorthorn, and two Red and White. Also, 88 Iowa cows qualified for the list of genetically superior grade dairy cows. The USDA-DHIA list for High Ranking Grade Cows in Iowa included two Ayrshire, two Brown Swiss, one Guernsey, 79 Holstein, one Jersey, and five Red and White. "Recent waves of herd expansions in the Upper Midwest and western states have increased dramatically the demand and prices for quality dairy replacements," Faust said. "Prices for springing dairy heifers have been at all-time highs. These record high prices and tight supplies have caused some dairy producers to consider sacrificing quality when purchasing herd replacements. "Some of our work at Iowa State University shows that paybacks for high quality dairy genetics are cost effective for all dairy herds, including herds that are expanding," Faust continued. "For example, investments in cattle are 35 to 40 percent of total expansion investments (excluding land), and, quite obviously, cattle must provide the income stream necessary to pay for the entire expansion project. For expansions, we have found that purchasing high genetic quality and healthy animals from a reliable source is justified due to its favorable net effects for profitability and lowered biosecurity risk. Our estimates suggest that purchasing healthy, high quality heifers can net an additional $800 or more per heifer over average quality heifers. The newest USDA-DHIA Elite Cow and High-Ranking Grade Cow Evaluations identify for breeders and commercial dairy producers potential sources for top genetics &endash; one key component for profitable dairying today." The USDA-DHIA Elite Cow and High Ranking Grade Cow lists are published in February, May, August, and November of every year. Cows included on these lists must meet a very stringent set of criteria for genetic merit based on Net Merit Dollars (NM$). Net Merit Dollars is an economic index that is computed for the USDA-DHIA genetic evaluations, and is the best single genetic measure available for predicting the profit potential of future progeny. The NM$ for a cow predicts the economic value of her combined contribution to progeny of genetic superiority for milk, fat and protein production; linear somatic cell score; and length of productive life. Elite and High Ranking Grade Cows are in the top 1 to 3 percent of their breed nationally for NM$. Daughters from May 1999 Elite Cows are expected to be more profitable for each lactation than daughters from cows born in 1990 by more than $126 for Ayrshire (top 2 percent), $152 for Brown Swiss (2 percent), $145 for Guernsey (2 percent), $181 for Holstein (1 percent), $163 for Jersey (1 percent), $142 for Milking Shorthorn (3 percent), and $114 for Red and White (3 percent), Faust said.
