Our objectives were to compare reproductive indicators from Holstein, Jersey and Crossbred dairies in 4 regions of United States of America and establish benchmarks for the 20% most efficient herds. Data from 290,351 cows and their records in DC305 were collected from February to November 2014 from a sample of 162 ABS customers. Regions (herds) represented were: Eastern (E; n = 28), Midwestern (MW; n = 58), Northwestern (NW; n = 10), and Southwestern (SW; n = 66). Univariated analyses were conducted with the MIXED and FREQ procedures of SAS using herd as the experimental unit. The Regions differed (P < 0.05) by mean (SE) herd size (E = 1,022 ± 580; MW = 690 ± 537; NW = 4,919 ± 496; SW = 2,760 ± 533) and kg of daily milk production (E = 37.4 ± 1.7; MW = 36.1 ± 1.6; NW = 32.3 ± 1.5; SW = 36.5 ± 1.6). Crossbred were not represented in the South Regions and Jerseys not represented in MW, making this effect significant (P < 0.05). The West Regions had a lower use of timed AI (P < 0.05) than E and MW (E = 46.1%; MW = 49.1%; NW = 17.6%; SW = 15.4%); but a lower conception rate (CR) (P < 0.05) than E and MW Regions (E = 36.6%; MW = 36.9%; NW = 31.5%; SW = 32.7%). Regarding insemination risk, only MW did lower (P < 0.05) than the other 3 Regions (E = 63.8%; MW = 52.8%; NW = 62.3%; SW = 61.8%). As a result, the E Region had the best pregnancy risk (PR) and MW the lowest (E = 22.9%; MW = 18.2%; NW = 20.0%; SW = 20.3%). The West Regions reported a higher (P < 0.05) pregnancy loss (E = 11.4%; MW = 10.3%; NW = 16.0%; SW = 13.3%). The 20% most efficient herds based on PR ranking (n=71) had a mean PR of 24%. Breeds were represented in both strata and was not a significant effect (P > 0.05). The top 20% had a 10 points higher insemination risk (mean 64%) and a 6 points higher CR (mean 38%) than bottom 80% (P < 0.05). Additionally, they breed open cows at pregnancy diagnosis 3 days earlier (mean 10 ds), but did not differ in timed AI usage (P > 0.05). The top 20% herds were not different in their daily milk production, voluntary waiting period, and pregnancy loss in comparison with the bottom 80% (P > 0.05). Despite regional differences, the best combination of factors led the East Region to achieve the highest PR. The top 20% herds in PR had higher overall reproduction but did not differ in herd management performance with the bottom 80%. Further analysis is needed.
