Benefits of technology

[0010]The present inventor investigated the effects of various genes of the IFNT signaling pathway and discovered that several of these genes comprise SNPs that are correlated with increased fertilization rate, or embryo survival rate, or both, and these SNPs may be used in breeding programs or other cattle testing or selection programs for cattle with improved fertility, more specifically for increased pregnancy rate in cattle. Accordingly, in one embodiment, the present invention provides a collection, or an array, of at least two of isolated polynucleotide molecule species selected from the group consisting of (1) an isolated polynucleotide comprising at least 12 consecutive nucleotides surrounding position of 1296 of SEQ ID NO:1; (2) an isolated polynucleotide comprising at least 12 consecutive nucleotides surrounding position of 213 of SEQ ID NO:2; (3) an isolated polynucleotide compris

Problems solved by technology

Such restructuring of the dairy cattle genome over the past 30 years due to intense selection for production traits may have resulted in a hitchhiking effect on a large number of loci adversely affecting fertilization rate and embryo survival, leading to dairy cattle genotypes that are suboptimal for reproductive competence (Royal et al., 2000; Lucy, 2001).
The decrease in dairy cattle fertility is a worldwide problem and a major cause of economic loss and cow culling in the global dairy herd.

Embodiment Construction

[0020]It has now been found that many genes encoding proteins of the IFNT signaling pathway contain single nucleotide polymorphisms (SNPs), and certain of these alleles correspond to increased fertilization rate, or embryonic survival rate, or both, in dairy cattle, and the beneficial effects of these alleles are additive. Specifically, it has been discovered that SNPs exist in the following genes: growth hormone receptor (GHR), osteopontin (OPN / SPP1), POU1F1, signal transducer and activator of transcription (STAT1), signal transducer and activator of transcription (STAT5A), bovine uterine milk protein (UTMP), and fibroblast growth factor 2 (FGF2).

[0021]These SNPs are summarized in the Table 1 below.

Description

FIELD OF THE INVENTION[0001]The present invention relates to methods of genetic testing of cattle using molecular genetic methods by assaying for the presence of at least one genetic marker which is indicative of fertility or embryonic survival.BACKGROUND OF THE INVENTION[0002]Dairy cows are significant investments for dairy farmers, and enormous efforts, such as animal breeding and artificial insemination, have been and continue to be invested in ensuring that the animals have high and sustained productivity, and that the milk produced is of high quality. About 50 quantitative trait loci (QTL) affecting milk production traits have been identified (Bagnato et al., 2008; Lipkin et al., 2008). The dairy cattle genome has been significantly restructured over the past 30 years due to intense selection for production traits.[0003]Such restructuring of the dairy cattle genome over the past 30 years due to intense selection for production traits may have resulted in a hitchhiking effect on...
