DOI: 10.1093/jas/skaa278.450
Abstract: The reproductive performance of dairy herds is a determinant factor in their production efficiency and long-term profitability. While the genetic improvement of fertility in cows has been a top breeding objective, its success has been… read more here.

DOI: 10.1093/jas/skac340
Abstract: Biologically informed single nucleotide polymorphisms (SNP) impact genomic prediction accuracy of the target traits. Our previous genomics, proteomics, and transcriptomics work identified candidate genes related to puberty and fertility in Brahman heifers. We aimed to… read more here.

DOI: 10.1186/s12864-020-07031-w
Abstract: Background Phenotypic performances of livestock animals decline with increasing levels of inbreeding, however, the noticeable decline known as inbreeding depression, may not be due only to the total level of inbreeding, but rather could be… read more here.

DOI: 10.21451/1984-3143-ar2018-0018
Abstract: The use of genomics has improved response to selection for functional traits with low heritability such as fertility traits. Much of the work on fertility traits has been performed through use of genome-wide association studies… read more here.

DOI: 10.21451/1984-3143-ar2018-0054
Abstract: Fertility performance is a key driver of the efficiency and profitability of seasonal-calving pasturebased systems of milk production. Since the 1990’s and early 2000’s, most countries have placed varying levels of emphasis on fertility and… read more here.

DOI: 10.3168/jds.2019-17068
Abstract: Elongation of the preimplantation conceptus is a requirement for pregnancy success in ruminants, and failures in this process are highly associated with subfertility in dairy cattle. Identifying genetic markers that are related to early conceptus… read more here.
