osteoporosis is considered as an important public health problem especially in postmenopausal women. there are some hypotheses support the contributory effect of pregnancy and lactation on osteoporosis later in life. high calcium demand during pregnancy and lactation and low estrogenic state support those hypotheses. numerous studies have investigated on the issue but there is no consensus abou...

An extensive review of Wisconsin Veterinary Diagnostic Laboratory(WVDL) accessions along with the results of slaughter house surveys indicate that copper is accumulating in the livers of Wisconsin Holsteins of all ages. Two hundred eleven WVDL accessions were reviewed based on breed(Holstein), age and results of inductively coupled plasma-mass spectroscopy(ICP-MS) liver element testing. The ove...

OBJECTIVE Holsteins are known as the world's highest-milk producing dairy cattle. The purpose of this study was to identify genetic regions strongly associated with milk traits (milk production, fat, and protein) using Korean Holstein data. METHODS This study was performed using single nucleotide polymorphism (SNP) chip data (Illumina BovineSNP50 Beadchip) of 911 Korean Holstein individuals. ...

A genetic correlation near unity between ovulation rate in heifers and later twinning frequency led to consideration of using measures of ovulation rate in heifers for each estrous cycle, beginning at puberty, to increase accuracy of selection for twinning rate. An initial evaluation with a multiple trait animal model for predicting breeding values included six genetic groups: 1) selected Scand...
