Erratum to: Associations of POU1F1 gene polymorphisms and protein structure changes with growth traits and blood metabolites in two Iranian sheep breeds

The erratum published in the March 2015 issue to this article did not point out another error in the misprinted equations (i), (ii) and (ii). The correct equations (as submitted by author) are:

• (i) Y_ijklm=µ+G _i+B _j+S _k+T_l+M_m+b₁(D_ijklm-^D)+ e_ijklm

• (ii) $\mathrm {Y}_{\text {ijklm}} =\upmu +\mathrm {G}_{\mathrm {i}} +\mathrm {B}_{\mathrm {j}} +\mathrm {S}_{\mathrm {k}} +\mathrm {T}_{l} +\mathrm {M}_{\mathrm {m}} +\mathrm {b}_{1} (\mathrm {D}_{\text {ijklm}} -^{\mathrm {D}})+\;\mathrm {b}_{2} (\text {AW}_{\text {ijklm}} -^{(AW)})+\;\mathrm {b}_{3} (\text {BW}_{\text {ijklm}} -^{(BW)})+\mathrm {e}_{\text {ijklm}}$

• (iii) $\mathrm {Y}_{\text {ijklm}} =\upmu +\mathrm {G}_{\mathrm {i}} +\mathrm {B}_{\mathrm {j}} +\mathrm {S}_{\mathrm {k}} +\mathrm {T}_{\mathrm {l}} +\mathrm {M}_{\mathrm {m}} +\mathrm {b}_{1} (\mathrm {D}_{\text {ijklm}} -^{\mathrm {D}})+\mathrm {b}_{4} (\mathrm {A}_{\text {ijklm}} -^{\mathrm {A}})+\;\mathrm {e}_{\text {ijklm}}$

We apologize for the errors in the published article and for missing other errors in the erratum published subsequently.
