Dairy Herd Improvement Letter Vol 55 PDF Download

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.
