PTCH1 polymorphisms relate to increased weight gain of porcine populations in the context of a swine influenza outbreak

Marker	Lifetime Daily Gain (grams/day)	Wean End Daily Gain (grams/day)
619	23.69 (0.023)	21.88 (0.036)
660	14.19 (0.047)	15.16 (0.033)
661	11.93 (0.149)	13.53 (0.105)
662	6.81 (0.120)	7.81 (0.076)

The effect of PTCH1 polymorphisms on the growth (grams/day) of one copy of favorable allele (relative to the major allele). All results are shown as the relative increases in weight gain relative to the major allele (p value). Lifetime Daily Gain = Final weight minus birth weight. Wean End Daily Gain (called something different in methods) = Final weight minus weight at time of weaning.
