BMC Veterinary Research

Table 2 Summary of markers with largest effects (p < 0.001) including the number of regions and number of chromosomes that they are found in

Trait¹	# of BTA²	# of regions	Combined absolute effect³	Combined relative variance
TMT	28	77	38 s	6.3%
AT	27	79	2 s	5.1%
TP	28	78	9 s	5.3%
DT	27	76	43 s	6.4%
MMF	27	75	0.45 kg/min	6.2%
AVGF	28	77	0.26 kg/min	5.4%

¹TMT – total milking time, AT – ascending time, TP – time of plateau, DT – descending time, MMF – maximum milk flow, AVGF – average milk flow.
²BTA – bos Taurus autosome.
³Combined Absolute Effect – refers to the absolute largest effect that the markers can have on each of the milk flow traits by summing absolute effects across each region.
