Because much of the cost of a cow is the feed and labor needed to maintain
her, fewer but higher yielding cows mean lower priced milk. Dairy herd
improvement ultimately benefits consumers.
That's why it's just as important to keep complete and accurate records as
it is to keep the cows contented. The National Cooperative Dairy Herd
Improvement Program has been tracking Bossy's milk yields since 1905.
Over the years, this program has made enormous contributions to dairy cattle
breeding. ARS scientists receive the lactation records of all herds enrolled in
the program and use the figures to rank the bulls that sire the nation's dairy
cows and to rank the cows themselves.
The results of years and years of scientific dairying? Milk production has
been trending upward for more than 25 years in the United States-from about
117,000 million pounds in 1970 to more than 150,000 million pounds in 1994-even
though the number of milk cows has been reduced.
