(Apr 27, 2017): A sum of 21,004 new QTL added to the database. The current total number of QTL in the database: 125,753 [Breakdown by species -- Cattle: 98,090; Chicken: 6,791; Horse: 1,275; Pig: 17,955; Sheep: 1,515; Rainbow trout: 127] (New additions less obsolete/retracted ones: Catfish: 0; Cattle: 2,758; Chicken: 158; Horse: 30; Pig: 17,955; Sheep: 103; Rainbow trout: 0 -- Net increase: 21,004).

Other developments:
(1) Access to the Wordle representation of QTL/association-mapped traits by year, across all species, can now be found in the data summary area of each species on the Animal QTLdb. (2) Efforts have continued to improve QTLdb curator/editor/release tools and procedures in terms of debugs, adding new parameters, and optimize the procedures for various data updates, especially to meet the challenges accommodating multiple genomes, aligning map coordinates between linkage maps, SNP represented coordinates, manually entered coordinates, and conversions between where needed.
