Polymorphism of insulu00cdnico factor Type 1 (igf-1) and its use as a DNA Marker that improves the duration of postpartum anoestrus in cattle.

摘要

The present Invention relates to the identification of a single nucleotide polymorphism located in the promoter region of the bovine igf-i Gene and its association with the length of postpartum anestrus, Introducing the genotype AA interval delivery resumption of ovarian cyclicity.The Association of Variants / B of igf-i with duration of anestrus postpartum Holstein Dairy cows were evaluated in 70, and there was no effect of genotype AA a resumption of ovarian cyclicity Birth interval Shorter.The Association of Variants / B of igf-i with duration of anestrus postpartum Holstein Dairy cows were evaluated in 70, and there was no effect of igf-i genotype on Milk Production, and the evolution of body condition.
