EXTENSION CORNER Sire Evaluation fur Somatic Cell Scores by Larry W. Specht Professor of Dairy Science Penn State University The USD A Animal Improve ment Programs Lab (AIPL) has developed a sire evaluation program for the genetic im provement of mastitis resis tance. Plans are to release this information on sires with January 1994 genetic evaluation summaries. AIPL calculates and publishes genetic evalutation for produc tion traits (milk, fat and protein) using DHIA records. Genetic evaluations for mastitis resis tance will be producedfrom DHIA somatic cell count data on daughters or individual sires with procedures similar to those used with production traits. Somatic cell counts (raw scores) will be converted to somatic cell scores (SCS) for the evaluation. Geneticists caution that dairy men should not over emphasize mastitis in their sire selection strategy. They agree that _=== Welcome ==rr NEW MEMBERS Since June to November, 1993 by County Armstrong.

However, when bulls with similar production values are available, it would be prudent to select those with the lower SCS evaluations. It should also be pointed out that no amount of selection intensity for lower SCS scores with replace good management in controlling mastitis. Other changes in the January 1994 sire evaluations are (1) adjustment to the milk. fat. protein dollar values (M,EP,S) to account for the cost of additional feed required for the higher production by daughters of the higher ranking sires, (2) inclusion of production life (PL) in the new evaluation index and (3) creation of a Net Merit (NM) index that will include the production trails as well as the SCS and PL values. Values from the Net Merit index have been compared to those from the M,F,P,S index for a large sample of sires. The correlation between the two indexes is 0.96. Thus, there will not be a lot of change in the rankings of individual sires when the January 1994 summa ries are published. Brickcr, Fred M Gather, Clair E Gat her, Chris Gold Hulsleins.

Hildicth Dany Acres Multiple Component Pricing is Here Multiple Component Pricing can be defined as a method in which the pricing of milk uses all the compo nents of milk, including butterfat, protein and/or solids-not-fat. The dairy industry has priced milk, based on weightand butterfat content, since the early 1900’s. For sometime now the systerr has not been reflective of commerci, demand m the market place. To be mote specific, the con sumers are demanding lowfat dairy products. Muluple Component Pricing would send the consumer a more positive and accurate market or economic signal. So far in Pennsylvania, federal order 36, which comprises Eastern Ohio- Western Pennsylvania; the MCP has taken effect and is being used to price milk. Low Somatic Cell is also important totheMCP. For example, Producers' A and B have milk with identical protein content but differ greatly in somatic cell counts (SCC). Producer A has a SCC of 150,000 while pro ducer B has a SCC of 900.000. Pro ducer A is more desirable because of the greater value to cheese manufac turers. The rule of thumb is that cheese yields increase as SCC tests decrease. When all summed up in one sentence, high protem/low SCC milk has the most economic value. Winter District Meetings The November Fall District Director Meetings are finished and it's now time to prepare for the district DHIA Winter meetings to be held in January or February. The districts that will need to hold meetings are the districts where an election needs to lake place. It was agreed at the Fall District Meetings that other districts may meet with those districts where elections need to take place and an agenda will be sent to the local committees for them to make those decisions. The change in bylaws ami new districts will go into el feet January 1, 1994. This change will separate the state into smaller districts for state represen tation. The following will outline the districts where some meetings have been held and some need to establish a date and place. The nominating committee fnim each county will need to contact the other counties in their district. These meetings need to take place after Jan. 1, but before the annual meeting of Feb. 18,1994. They arc as follows: incaster Firming, Let's take a closer look at the impact somatic cell can have on the MCP. The table enclosed shows the so matic cell adjustment that would be made for each pound of protein. For example, if producer A is less than 100,000 somatic cell count, than for each pound of protein, a posmve 11 cent adjustment will be made. However, in another situation where producer B would have a somatic cell of more than 900,000, that producer would be deducted a total of 11 cents per pound of protein.

Saturday, January 22, 1994-C9 buit. if producer A and Producers have a 3.2 percent protein content To determine the effect multiply the appropriate somanc cell adjustment by the protein content tocalculate the somatic cell adjustment on a per hun dredweight basis. To illustrate. Producer A would re ceive a posiuve 35.2 cents per hun dred weight of milk (3.2 x 11 cents) somatic cell adjustment. In another situation Producer B would have a negative of 35.2 cents per hundred weight of milk (3.2 x 11. cents) so mauc cell adjustment. This essen tially means that 35.2 cents per hun dred weight would be deducted from Producer B's milk check. Basically, a producer who maintains a butterfat of 3.5% and a protein of 3.2%, and maintains an acceptable somanc ceil count, will maintain the same milk price as shown under the traditional pricing.
