Whole genome QTL mapping for growth, meat quality and breast meat yield traits in turkey.

Aslam ML, Bastiaansen JW, Crooijmans RP, Vereijken A, Groenen MA - BMC Genet. (2011)

Bottom Line: Forty-five quantitative trait loci were detected across all traits and these were found in 29 different regions on 21 chromosomes.Out of the 45 quantitative trait loci, twelve showed significant (p<0.01) evidence of linkage while the remaining 33 showed suggestive evidence (p<0.05) of linkage with different growth, growth curve, meat quality and breast yield traits.Pleiotropic effects or close linkages between quantitative trait loci were suggested for several of the chromosomal regions.

Identified QTL on turkey chromosome 5 affecting growth, meat quality and breast yield traits. BW01, BW17, BW40, BW60, BW80, and BW120 are the BW at days 1,17, 40, 60, 80, and 120 of age; PBM = percentage breast meat at 20 wk of age; BrL = breast length at 20 wk of age; BrW = breast width at 20 wk of age; PDL = percent drip loss at 20 wk of age; pHu = ultimate pH at 20 wk of age; L* = lightness at 20 wk of age; a* = redness at 20 wk of age; b* = yellowness at 20 wk of age; Aswt = upper asymptote (estimated growth curve parameter); tmid = inflection point at 50% asymptote (estimated growth curve parameter); scale = constant that is proportional to the overall growth rate (estimated growth curve parameter).

Figure 1: Identified QTL on turkey chromosome 5 affecting growth, meat quality and breast yield traits. BW01, BW17, BW40, BW60, BW80, and BW120 are the BW at days 1,17, 40, 60, 80, and 120 of age; PBM = percentage breast meat at 20 wk of age; BrL = breast length at 20 wk of age; BrW = breast width at 20 wk of age; PDL = percent drip loss at 20 wk of age; pHu = ultimate pH at 20 wk of age; L* = lightness at 20 wk of age; a* = redness at 20 wk of age; b* = yellowness at 20 wk of age; Aswt = upper asymptote (estimated growth curve parameter); tmid = inflection point at 50% asymptote (estimated growth curve parameter); scale = constant that is proportional to the overall growth rate (estimated growth curve parameter).

Mentions: Two QTL regions were detected on chromosome 5, the first region showed a QTL for development in weight (BW17 and BW40) at 60-63 cM, and the second region showed a QTL for BrL at 113 cM. The QTL for BrL was in a separate region. Another region with QTL for development in BW traits (BW40, BW60 and BW80) was located on chromosome 8 at cM position 1 (Figure 1 &2).
