USDA releases third report from its Dairy 2014 study

The USDA’s National Animal Health Monitoring System (NAHMS) has released Health and Management Practices on U.S. Dairy Operations, 2014, the third report from its Dairy 2014 study.

 

Dairy 2014 is NAHMS fifth study of the U.S. dairy industry. The study was conducted in 17 of the nation’s major dairy states. Data presented in the study represent 80.5 percent of U.S. dairy operations and 81.3 percent of U.S. dairy cows.

Here are a few highlights from the NAHMS’ third Dairy 2014 descriptive report:

  • In 2013, the most common clinical diseases reported by producers were mastitis (24.8 percent of cows), any degree of lameness (16.8 percent), infertility (8.2 percent), and metritis (6.9 percent).
  • Most operations used artificial insemination to natural estrus for first-service breeding for the majority of heifers (59.4 percent) or cows (51.5 percent). A higher percentage of operations used artificial insemination to induced estrus for first-service breeding in cows than in heifers.
  • Nearly all operations (94.8 percent) would very likely consult their private veterinarian for general information about a foreign animal disease, should an outbreak occur.
  • The majority of operations (70.6 percent) used rectal palpation to determine pregnancy status. Ultrasound was used by 44.1 percent of operations, and abdominal palpation (ballottement/bumping) was used by 22.6 percent. On average, pregnancy status was determined within 53.0 days of breeding when using rectal palpation and 35.4 days when using ultrasound.
