Multiple ovulation embryo transfer (MOET) is used to make more rapid progress in animal breeding schemes. On dairy farms, where female calves are more desired, embryo sex diagnosis is often performed before embryo transfer. Fresh transfers have been

Nykyaikaisessa karjanjalostuksessa huippuemien jälkeläismäärää voidaan lisätä alkiohuuhtelujen avulla. Huuhdeltavan eläimen munasarjat aktivoidaan hormoneilla, jolloin ovulaatiossa irtoaa kerralla jopa kymmeniä munasoluja. Eläin keinosieme

The aim of this study was to evaluate embryo production in superovulated Holstein-Friesian dairy heifers and cows inseminated with either X-sorted spermatozoa (2 million/dose) or unsorted semen (15 million/dose). Experiment 1 at the research farm inv

Lypsykarjalla sperman sukupuolilajittelulla on monta etua: nuorten sonnien testityttärien tuottaminen pienemmillä siemennysmäärillä, huippusonnien X-sperman käyttö parhaille lehmille ja lihasonnien Y-sperma keskitason lehmille. Tehokkain tapa

Oocyte quality affects subsequent embryo development and quality. We examined the impact of bovine oocyte in vitro maturation (IVM) conditions on subsequent embryo yield, quality and cryosurvival. Cumulus-oocyte complexes (COCs) were sampled for cyto

SummaryWe studied whether bovine embryos developing after in vitro fertilization (IVF) with sex-sorted spermatozoa differed in developmental kinetics, quality and sex ratio from embryos produced with unsorted spermatozoa. Abattoir-derived oocytes wer

We report a method for multiplex genotyping of bovine embryo microblade biopsies. We have tested the reliability of the method and the viability of the embryos in vitro and in vivo. Two polymorphic gene markers (GHR F279Y and PRLR S18N) associated wi

Oxygen consumption is a useful parameter for evaluating embryo quality, since it provides a valuable indication of overall metabolic activity. Over the years, several approaches have been used to measure the respiration rates of individual embryos, b
