Anim Sci J 2020 Jan;91(1):e13408

Institute of Agrobiological Sciences, National Agriculture and Food Research Organization (NARO), Tsukuba, Japan.

We examined the allelic expression and positioning of two pluripotency-associated genes, OCT4 and SOX2, and two housekeeping genes, ACTB and TUBA, in 4- and 8-cell porcine embryos utilizing RNA and DNA fluorescence in situ hybridization (FISH) in single blastomeres. The proportion of blastomeres expressing SOX2 bi-allelically increased from 45% at the 4-cell stage to 60% at the 8-cell stage. Moreover, in 8-cell embryos, SOX2 was expressed bi-allelically in significantly more blastomeres than was the case for OCT4, and this was associated with a tendency for SOX2 alleles to move toward the nuclear interior during 4- to 8-cell transition.

Analysis of differential strategies to enhance detection of low-abundance proteins in the bovine serum proteome.

Anim Sci J 2020 Jan;91(1):e13388

Department of Animal Science, College of Agriculture and Life Sciences, Cornell University, Ithaca, NY, USA.

Serum-based biomarkers hold propitious applications for addressing livestock health, and management. However, discovery of protein biomarkers in complex biological fluids like serum is wholly intractable due to the large dynamic range of protein concentrations; that is, ˜10-12 high abundance proteins constitute >90% of the total protein content and effectively mask proteomic detection of low-abundance biomarkers. Toward addressing this limitation, we test a continuous elution size-based fractionation method, and two approaches that use affinity interaction-based separation of proteins in preparing bovine serum, and compare liquid chromatography tandem mass spectrometry protein identification to neat serum.

Effects of oocyte-derived paracrine factors on release of extracellular vesicles by murine mural granulosa cells in vitro.

Anim Sci J 2020 Jan;91(1):e13385

Laboratory of Applied Genetics, Department of Animal Resource Sciences, Graduate School of Agricultural and Life Sciences, The University of Tokyo, Tokyo, Japan.

Both oocytes and extracellular vesicles (EV) have emerged as critical regulators of mammalian follicular development; however, the possible interaction between the oocyte-derived paracrine factor (ODPF) and EV signals has never been examined. Therefore, to explore the possibility of an interaction between oocyte and EV signals, the effects of ODPFs on the biogenesis of EVs as well as the expression levels of transcripts related to EV biogenesis in mural granulosa cells (MGCs) were examined using mice. The results showed that, while oocyte coculture has some effects on the expression levels of transcripts related to EV biogenesis, the number of EV particles present in the conditioned medium were not significantly different between ODPF-treated and non-treated MGCs.

Effects of feeding early-harvested orchardgrass-perennial ryegrass mixed silage instead of heading stage harvested timothy silage on digestion and milk production in dairy cows.

Anim Sci J 2020 Jan;91(1):e13376

Hokkaido Agricultural Research Center, NARO, Sapporo, Japan.

We evaluated the effects of replacement of heading stage harvested timothy silage with early-harvested orchardgrass-perennial ryegrass mixed (OP) silage while maintaining or reducing concentrate input on dry matter intake (DMI), milk production, nutrient digestibility, and N balance in dairy cows. Nine multiparous Holstein cows were used in a replicated 3 × 3 Latin square design with three dietary treatments: TYL, a diet containing timothy silage where forage-to-concentrate ratio (FC) was 50:50; OPL, a diet containing OP silage where FC ratio was 50:50; and OPH, a diet containing OP silage where FC ratio was 60:40. We observed that an equal replacement of timothy with OP silage increased DMI, milk yield, milk protein production, and nutrient digestibility but decreased milk fat content (TYL versus OPL).
