Before fertility traits were incorporated into selection, dairy cattle breeding primarily focused
on production traits, which resulted in an unfavorable decline in the reproductive …

Milk and dairy products are valuable sources of food for humans. Increased milk yield and
changes in milk composition in dairy cows have been achieved through a variety of means …

Background Genetic progress for fertility and reproduction traits in dairy cattle has been
limited due to the low heritability of most indicator traits. Moreover, most of the quantitative …

Abstract Background The Nordic Red Cattle consisting of three different populations from
Finland, Sweden and Denmark are under a joint breeding value estimation system. The long …

Reduced female fertility could cause considerable economic loss and has become a
worldwide problem in the modern dairy industry. The objective of this study was to detect …

Background Domestication, breed formation and intensive selection have resulted in
divergent cattle breeds that likely exhibit their own genomic signatures. In this study, we …

Female fertility in Holstein cattle can decline when intense genetic selection is placed on
milk production. One approach to improving fertility is to identify the genomic regions and …

While single nucleotide polymorphism (SNP) is typically the variant of choice for population
genetics, copy number variation (CNV) which comprises insertion, deletion and duplication …

Mendelian variants can determine both insemination success and neonatal survival and
thus influence fertility and rearing success of cattle. We present 24 deficient homozygous …

Background The advent of genomic information and the reduction in the cost of genotyping
have led to the use of genomic information to estimate genomic inbreeding as an alternative …
