This book was released on 2017-12-14 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Dairy Herd Improvement Letter, Vol. 56: April 1980 The average pd's were studied for sires of first lactation cows on Official dhi test calving from 1973 through 1978. Only first lactations were used in order to provide figures more reflective of recent decisions. The use of later lactations would dilute the higher recent levels of sire merit. Table 1 gives the average pd's for 1973 and 1978 and the annual change for intervening years for milk, fat, and dollars. PD dollars (pds) is a combination of PD milk (pom) and PD fat (pdf) according to the national average milk price in 1979. Thus, pd$ x pdn) x pdf). All pd$ were computed by this formula. Changes frun year to year more clearly show the changes (progress) taking place than would the presentation of annual averages. The annual changes are not uniform across or even within breeds but are predominately positive. Some fluctuations are due to limited numbers of cows and sires in some breeds. The fluctuations are smaller in Holsteins, probably because of the larger number of cows. The sires of later lactation cows, representing a number of years of first calvings, would smooth out the year to-year variation frun sires of first lactation cows. In these data, first lactations were 25 to 30 percent of all lactations. The average sire is genetically better each year. The table gives the average annual changes in pom, pdf, and pd$. Each year dairy farmers need to increase the average pd's of sires used by those amounts, just to keep pace with national progress.

Book excerpt: Excerpt from Dairy Herd Improvement Letter, Vol. 56: December 1980 Information on feed and income, in addition to milk and fat production, was reported by the Iowa, New York, North Carolina, Pennsylvania, and Washington dairy records processing centers. Averages for this additional information and milk and fat are presented separately for herd records with feeding information. Production averages from herds on official plans included 92 percent of the herds and 93 percent of the cows enrolled in these plans as of January 1, 1980, a slight increase from the previous test year. Production averages from herds on nonofficial plans included 84 percent of the herds and 78 percent of the cows enrolled in these plans as of January 1, 1980, a slight decrease from the previous test year. Records were not included if the herds represented had fewer than five cows, average milk production less than or greater than pounds, average fat production less than 92 or greater than pounds, average percent fat less than or greater than or time on test less than than 12 months. Herd and cow numbers and averages reported in State newsletters may differ from values reported in this Letter because a State may use a different test year.
