¹Bos taurus chromosome (BTA) location of the locus

²Region associated locus is located in (in Mb) as measured by numbered nucleotides in reference to the UMD 3.1 genome assembly (http://bovinegenome.org/?q=node/61; accessed 15 September 2016)

³The citation number for each study a locus was previously associed in is listed

⁴Traits previously associated with loci abbreviated as follows: AISC - number of inseminations to conception in cows; AISC - number of inseminations to conception in heifers; CI - calving interval; HCR1 - conception rate to first insemination in heifers; DFS - days to first service; DPR - daughter pregnancy rate; FTI - fertility index; HCR - heifer conception rate; ICF - interval (in days) from calving to first insemination; IFLC - days from first to last insemination in cows; NRRC - 56 day non return rate in cows; NRRH - 56 day non return rate in heifers; P28- pregnancy success at day 28 post embryo transfer; P42 - pregnancy success within first 42 days of mating; TBRD - number of times bred to conception. If multiple traits are listed from different studies the citation number for study is listed in superscript brackets

⁵Cattle breeds loci were previously identified are listed with the country or region the population was from indicated in superscript as follows: Australia - A; Canada - C; Ireland - I; Nordic - N; United States - U

⁶Phenotype of the current study the loci was associated with: conception rate at first AI service - CCR1 and TBRD
