(Apr 26, 2022): A sum of 752 new correlations [Breakdown by species -- Pig: 156; Cattle: 172; Chicken: 170; Sheep: 254; ] and a sum of 155 new heritability data [Breakdown by species -- Pig: 44; Cattle: 47; Chicken: 24; Horse: 1; Sheep: 36; Goat: 3; ] have been curated into the CorrDB. To date, the total number of correlation data in the database: 24,856 [Breakdown by species -- Cattle: 13,003 (on 393 traits); Chicken: 1,625 (on 90 traits); Horse: 209 (on 27 traits); Pig: 7,737 (on 267 traits); Sheep: 1,971 (on 93 traits); Goat: 311 (on 32 traits)], and total heritability data: 4,474 [Breakdown by species -- Cattle: 2,243 (on 426 traits); Chicken: 343 (on 120 traits); Horse: 123 (on 53 traits); Pig: 1,491 (on 306 traits); Sheep: 269 (on 124 traits); Goat: 5 (on 2 traits)], curated from 441 publications.
( This is a joint release with the 47th QTLdb release.)

Database developments: (1) Direct data download of correlation data and heritability data is made available. The data deposition for direct download will be synced upon each database release. (2) The curator tools have been extensively re-developed (involving 7 scripts serving 18 views/functions) in the way how "trait variants" (previously called "sibling traits") information is curated. This improvement is aimed not only to bring the erratic livestock traits curation to be practically doable, but also to gear the management of such data towards a better structure in terms of information disseminations and ontology developments. (3) As part of the efforts implementing trait variant management, more than 5 user view pages were modified to accommodate the changes.
