(Dec 30, 2025): A sum of 1,977 new correlations [Breakdown by species -- Cattle: 713; Chicken: 221; Horse: 6; Sheep: 917; Goat: 120; ] and a sum of 342 new heritability data [Breakdown by species -- Pig: 8; Cattle: 137; Chicken: 24; Horse: 3; Sheep: 154; Goat: 16] have been curated into the CorrDB. To date, the total number of correlation data in the database: 48,539 [Breakdown by species -- Cattle: 17,933 (on 381 traits, 528 trait variants); Chicken: 5,670 (on 119 traits, 317 trait variants); Horse: 230 (on 31 traits, 6 trait variants); Pig: 13,045 (on 240 traits, 358 trait variants); Sheep: 7,538 (on 136 traits, 493 trait variants); Goat: 4,123 (on 93 traits, 190 trait variants);], and total heritability data: 8,213 [Breakdown by species -- Cattle: 3,173 (on 444 traits, 546 trait variants); Chicken: 885 (on 174 traits, 282 trait variants); Horse: 145 (on 58 traits, 7 trait variants); Pig: 2,107 (on 287 traits, 420 trait variants); Sheep: 1,364 (on 176 traits, 478 trait variants); Goat: 539 (on 88 traits, 156 trait variants);] curated from 841 publications.

( This is a joint release with the 58th QTLdb release.)

In addition, a number of trait data updates were made that affected 57 correlations and 62 heritability data in all 6 species. Data updates also included changes related to 40 pig heritability data.

Database development notes:
(1) The CorrDB data‑curation pipeline was originally designed with the assumption that each data report pertains to a (single) species. To handle the uncommon cases where a publication includes data from multiple species, we have introduced optional exceptions that allow trait measurement data from multiple species in a single publication be curated to appropriate species by the same curator (curator accounts/platforms are species dependent).
