Abstract
We aimed to identify the functional characteristics of the corpus luteum (CL) by color Doppler ultrasonography and changes in interferon-stimulated gene (ISG) expression in peripheral blood mononuclear cells (PBMCs) during early pregnancy in beef cows. We then aimed to use these features to establish earlier pregnancy diagnosis methods. In experiment 1, the CL size and blood flow were accessed by Doppler ultrasonography, and the PBMCs were isolated on Days 8, 12, 15, 18, 20, 22, 25, 30, 45, and 60 post-timed artificial insemination (TAI) from pregnant (n = 10) and nonpregnant cows (n = 12). The abundance of ISG (OAS1, MX1, MX2, and ISG15) transcripts was measured by quantitative PCR. Analyses of OAS1 and MX2 expression in isolated PBMCs (ISG-PBMC method) and Doppler imaging of CL (Doppler-US method) were performed to test the accuracy of these methods for the diagnosis of pregnancy on Day 20 post-TAI (n = 110; experiment 2). In experiment 1, the luteal volume and blood flow were reduced in nonpregnant cows during the first weeks post-TAI, but an evaluation of CL vascularization and size was efficient in identifying nonpregnant cows on Day 20 post-TAI. The expression of ISGs in PBMCs can be stimulated by the presence of a viable conceptus between Days 15 and 22 post-TAI, and the expression of these genes reaches a peak on Day 20. In experiment 2, the Doppler-US and ISG-PBMC methods resulted in similar specificity (85.5 and 87.7%, respectively). However, only the Doppler-US method resulted in 100% sensitivity. In conclusion, the greatest abundance of ISGs in PBMCs and a high detection of luteolysis by Doppler imaging on Day 20 post-TAI can be feasibly used for the earlier detection of nonpregnant cows in reproductive programs. The level of accuracy for our described pregnancy methods is high on Day 20 (80%-91%), but only the Doppler imaging method results in an absence of false-negative diagnoses.

Abstract
The objectives of the present study were to establish a nonsurgical transfer method for elongating bovine conceptuses and to combine this method with biopsy and sexing. Bovine conceptuses were recovered from donor cows on days 13-14 of the estrus cycle. In experiment 1, day 13 conceptuses were transferred to recipient cows using a standard day 7 embryo transfer (ET) method. The pregnancy rate of day 13 conceptus transfer (CT) is comparable to that of day 7 ET. In experiment 2, day 14 conceptuses were transferred using modified methods (balloon catheters or ET guns with modified sheaths). Using the standard ET method, no pregnancies were obtained; however, when balloon catheters or ET guns with modified sheaths were used, the pregnancy rates after CT were 48.0% and 44.8%, respectively. In experiment 3, day 14 conceptuses were biopsied without a micromanipulator, sexed using the loop-mediated isothermal amplification method and transferred to recipient cows. The pregnancy rate of biopsied conceptuses was 46.2% and did not differ significantly from that of unbiopsied conceptuses. Moreover, all pregnant cows transferred conceptuses following biopsy and sexing delivered calves with the expected sexes. These results suggested that the nonsurgical bovine CT method was comparable to day 7 ET and that this technique enables biopsy and sexing without expensive equipment such as a micromanipulator or specialized skills.

Abstract
BACKGROUND Early identification of viable pregnancy is paramount for successful reproduction. Detection of specific signals from pre-implantation viable embryos in normal pregnancy circulation would indicate initiation of embryo-maternal interaction and create a continuum to accurately reflect embryo/fetal well-being post-implantation. Viable mammalian embryos secrete PreImplantation Factor (PIF), a biomarker which plays key, multi-targeted roles to promote implantation, trophoblast invasion and modulate maternal innate and adaptive immunity toward acceptance. Anti-PIF monoclonal antibody (mAb-based chemiluminescent ELISA) accurately detects PIF in singly cultured embryos media and its increased levels correlate with embryo development up to the blastocyst stage. Herein reported that PIF levels (ELISA) in early maternal serum correlate with pregnancy outcome. METHODS Artificially inseminated (AI) blind-coded Angus cattle (N = 21-23) serum samples (day 10,15 & 20 post-AI) with known calf birth were blindly tested, using both non-pregnant heifers (N = 30) and steer serum as negative controls. Assay properties and anti-PIF monoclonal antibody specificity were determined by examining linearity, spike and recovery experiments and testing the antibody against 234 different circulating proteins by microarray. Endogenous PIF was detected using <3 kDa filter separation followed by anti-PIF mAb-based affinity chromatography and confirmed by ELISA and HPLC. PIF expression was established in placenta using anti-PIF mAb-based IHC. RESULTS PIF detects viable pregnancy at day 10 post-AI with 91.3% sensitivity, reaching 100% by day 20 and correlating with live calf birth. All non-pregnant samples were PIF negative. PIF level in pregnant samples was a stringent 3 + SD higher as compared to heifers and steer sera. Assay is linear and spike and recovery data demonstrates lack of serum interference. Anti-PIF mAb is specific and does not interact with circulating proteins. Anti-PIF based affinity purification demonstrates that endogenous PIF is what ELISA detects. The early bovine placenta expresses PIF in the trophoblast layer. CONCLUSION Data herein documents that PIF is a specific, reliable embryo-derived biomarker conveniently detectable in early maternal circulation. PIF ELISA emerges as practical tool to detect viable early pregnancy from day 20 post-AI.

Abstract
BACKGROUND In food production animals, especially cattle, the diagnosis of gestation is important because the timing of gestation directly affects the running of farms. Various methods have been used to detect gestation, but none of them are ideal because of problems with the timing of detection or the accuracy, simplicity, or cost of the method. A new method for detecting gestation, which involves assessing interferon-tau (IFNT)-stimulated gene expression in peripheral blood leukocytes (PBL), was recently proposed. PBL fractionation methods were used to examine whether the expression profiles of various PBL populations could be used as reliable diagnostic markers of bovine gestation. METHODS PBL were collected on days 0 (just before artificial insemination), 7, 14, 17, 21, and 28 of gestation. The gene expression levels of the PBL were assessed with microarray analysis and/or quantitative real-time reverse transcription (q) PCR. PBL fractions were collected by flow cytometry or density gradient cell separation using Histopaque 1083 or Ficoll-Conray solutions. The expression levels of four IFNT-stimulated genes, interferon-stimulated protein 15 kDa (ISG15), myxovirus-resistance (MX) 1 and 2, and 2'-5'-oligoadenylate synthetase (OAS1), were then analyzed in each fraction through day 28 of gestation using qPCR. RESULTS Microarray analysis detected 72 and 28 genes in whole PBL that were significantly higher on days 14 and 21 of gestation, respectively, than on day 0. The upregulated genes included IFNT-stimulated genes. The expression levels of these genes increased with the progression of gestation until day 21. In flow cytometry experiments, on day 14 the expression levels of all of the genes were significantly higher in the granulocyte fraction than in the other fractions. Their expression gradually decreased through day 28 of gestation. Strong correlations were observed between the expression levels of the four genes in the granulocyte fractions obtained with flow cytometry and with density gradient separation. CONCLUSIONS The expression profiles of ISG15, MX1, MX2, and OAS1 could be a useful diagnostic biomarker of bovine gestation. Assessing the expression levels of these genes in a granulocyte fraction obtained with density gradient separation is a practical way of detecting gestation in cows within three weeks of insemination.
