About DHIA
AgSource & Central Star offer full service DHI services in the United States offering on-farm milk recording and sampling services, laboratory analysis, data processing and creation of management information. AgSource & Central Star’s DHI Division equips dairy producers with information for effective herd management. AgSource & Central Star’s DHI reports include herd and individual cow performance measures that aid in managing milk production, fresh cows, reproduction, replacement animals, genetics, and milk quality.
DHI records measure a variety of performance factors – from milk production to SCC to dry period length to herd turnover to heifer reproduction- that allow dairy producers to effectively manage their businesses. DHI records remain the rock-solid pillar in dairy financial analysis and planning. No other record keeping entity has the positive impact for growth on the dairy as DHI records. AgSource & Central Star’s accurate, detailed, concise and relevant information takes DHI to the next level in managing dairies.
Cows on AgSource & Central Star’s DHI testing programs come in all herd sizes. By offering flexible, innovative programs, all types and sizes of dairies can effectively use DHI records to better manage their dairy businesses.
Testing Services
Milk testing provides benefits that include milk weights, somatic cell count, butterfat, and protein. Green County DHIA also has the capacity to pregnancy check (milk and blood serum); test for Johnes (milk sample); and do A1/A2 testing, BVD, Leukosis, and MUN (milk samples). Mastitis samples can test for 4 or 16 pathogens along with a pooled sample. Diagnostics can easily be tested with milk samples pulled on test day.
