Abstract
The aim of this study was to examine the effect of twin pregnancy, fetal laterality, the number of corpora lutea (CL) and cavitary CL on pregnancy losses in Holstein-Friesian cows with a positive pregnancy diagnosis based on ultrasonography between days 29-42 after AI. Pregnancy was confirmed by transrectal palpation between days 57-70 after AI and at the time of drying-off as well. Twin pregnancy rate was 8.4% at the time of the early pregnancy examination. Pregnancy loss did not differ between singleton- and twin-carrying animals either between days 57-70 of gestation or at drying-off. More losses occurred in singletons between days 29-42 and 57-70 in cows with cavitary than in cows with noncavitary CL (12.1% vs. 3.6%; P < 0.05) and in cows with double CL than in cows with single CL (7.3% vs. 3.6% %; P < 0.05). Between days 57-70 of gestation and drying-off this difference was still significant (20.7% vs. 3.7%; P < 0.001), while it was non-significant between cows with one CL (5.7%) vs. double CL (3.7%). Cavity occurrence was not affected by hormone therapy prior to AI (either PGF2α or OvSynch; 4.4% vs. 5.4%, respectively); however, the number of CL was reduced by the treatments (11.6 vs. 19.6%; P < 0.0005). In twin pregnancies there was no difference in the pregnancy losses between bilateral and unilateral pregnancies at any time point. The length of gestation was 278.2 ± 10.5 (singleton) and 267.4 ± 31.2 (twin) days, respectively (P < 0.01). The stillbirth ratio was higher in twin carriers than in singleton carriers (19.5% vs. 5.3%; P < 0.001).

Abstract
Dietary supplementation with propylene glycol (PG) increases in vitro production of high-quality embryos in feed-restricted heifers. The aim of the present study was to evaluate the effects of PG in feed-restricted heifers on follicular fluid insulin and insulin-like growth factor (IGF) 1 concentrations, expression of IGF system genes in oocytes and cumulus cells and the expression of selected genes in blastocysts. Feed-restricted (R) heifers were drenched with water or PG during induced oestrous cycles (400mL of PG or water/drench, daily drenching at 1600 hours for the first 9 days of the oestrous cycle). Ovum pick-up (OPU) was performed after superovulation to produce in vitro embryos and without superovulation to recover oocytes, cumulus cells and follicular fluid. OPU was also performed in a control group (not feed restricted and no drenching). Follicular fluid IGF1 concentrations were reduced by R, and PG restored IGF1 concentrations to those seen in the control group. In cumulus cells, expression of IGF1, IGF1 receptor (IGF1R) and IGF binding protein 4 (IGFBP4) was decreased in the R group, and fully (IGF1 and IGF1R) or partially (IGFBP4) restored to control levels by PG. Blastocyst perilipin 2 (PLIN2; also known as adipophilin), Bcl-2-associated X protein (BAX), SCL2A1 (facilitated glucose/fructose transporter GLUT1), aquaporin 3 (AQP3), DNA (cytosine-5)-methyltransferase 3A (DNMT3A) and heat shock 70-kDa protein 9 (HSPA9B) expression were decreased in R heifers; PG restored the expression of the last four genes to control levels. In conclusion, these results suggest that, during follicular growth, PG exerts epigenetic regulatory effects on gene expression in blastocyst stage embryos.

Abstract
Rapid genetic improvement in cattle requires the production of high numbers of embryos of excellent quality. Increasing circulating insulin and/or glucose concentrations improves ovarian follicular growth, which may improve the response to superovulation. The measurement of anti-Müllerian hormone (AMH) can help predict an animal's response to superovulation treatment. The aim of the present study was to investigate whether increasing circulating insulin concentrations, through propylene glycol (PG) drenches, could improve in vitro embryo production in oestrus-synchronised superovulated heifers with different AMH profiles. Holstein heifers were grouped according to pre-experimental AMH concentrations as low (L) or high (H). The PG drench increased circulating insulin and glucose concentrations and reduced β-hydroxybutyrate and urea concentrations compared with the control group. AMH was a good predictor of follicle and oocyte numbers at ovum pick-up (OPU), and of oocyte and embryo quality (AMH H>AMH L). PG in the AMH H group increased the number of follicles and blastocyst quality above that in the control group, but did not improve these parameters in the AMH L group. These results indicate that short-term oral PG supplementation modifies an animal's metabolic milieu and is effective in improving in vitro embryo production, after superovulation-OPU, more markedly in heifers with high rather than low AMH concentrations.

Abstract
Female, 8-week-old BALB/c mice were immunized with the progesterone complete antigen (P4-BSA). Two monoclonal antibodies (MAbs) against P4, named 8G6 and 11A11, were obtained by the lymphocyte hybridoma technique. The titers of the cell culture supernatant and ascitic fluid of MAb 8G6 were 1: 16,000 and 1:512,000, respectively, and the titers of the cell culture supernatant and ascitic fluid of MAb 11A11 were 1: 8000 and 1:256,000, respectively. The subtypes of the MAbs 8G6 and 11A11 were IgMκ. In specific analysis, both of the two MAbs did not react with estradiol. These data demonstrated that the MAbs 8G6 and 11A11 have a potential use for developing diagnostic reagents of progesterone.

Abstract
Progesterone (P4) is a steroid gonadal hormone that is mainly produced from the corpus luteum and placenta and has various biological functions, especially reproductive regulation. It is important to establish a specific and sensitive P4 enzyme-linked immunosorbent assay (ELISA) for the study of ovary activity and reproductive disorders. Therefore, we prepared a monoclonal antibody (MAb) in a completed antigen (11α-OH-P4-HS-OVA). Based on the MAb and our previously prepared completed antigen, a highly specific and sensitive ELISA was developed. In the present study, a competitive ELISA for the determination of P4 was described in dairy cow milk. It was found that P4 concentration in milk samples from five pregnant cows was significantly higher than that from five estrus cows. The diagnosis rate for pregnancy and non-pregnancy in 54 dairy cows were 93.3% and 95.8%, respectively, at 19 to 23 days after pregnancy by detecting milk P4 concentration. In summary, the developed ELISA is a potential tool for P4 research and offers an alternative, simple, rapid technique for detecting P4, especially in future large clinical investigations on pregnancy identification and reproductive disorders in dairy farms in China.

Abstract
Hot season is a major constraint to production and reproduction in buffaloes. The present work aimed to investigate the effect of season on ovarian function, developmental competence, and the relative abundance of gene expression in buffalo oocytes. Three experiments were conducted. In experiment 1, pairs of buffalo ovaries were collected during cold season (CS, autumn and winter) and hot season (HS, spring and summer), and the number of antral follicles was recorded. Cumulus oocyte complexes (COCs) were aspirated and evaluated according to their morphology into four Grades. In experiment 2, Grade A and B COCs collected during CS and HS were in vitro matured (IVM) for 24 hours under standard conditions at 38.5 °C in a humidified air of 5% CO2. After IVM, cumulus cells were removed and oocytes were fixed, stained with 1% aceto-orcein, and evaluated for nuclear configuration. In vitro matured buffalo oocytes harvested during CS or HS were in vitro fertilized (IVF) using frozen-thawed buffalo semen and cultured in vitro to the blastocyst stage. In experiment 3, buffalo COCs and in vitro matured oocytes were collected during CS and HS, and then snap frozen in liquid nitrogen for gene expression analysis. Total RNA was extracted from COCs and in vitro matured oocytes, and complementary DNA was synthesized; quantitative Reverse Transcription-Polymerase Chain Reaction was performed for eight candidate genes including GAPDH, ACTB, B2M, GDF9, BMP15, HSP70, and SOD2. The results indicated that HS significantly (P < 0.01) decreased the number of antral follicles and the number of COCs recovered per ovary. The number of Grade A, B, and C COCs was lower (P < 0.05) during HS than CS. In vitro maturation of buffalo oocytes during HS significantly (P < 0.01) reduced the number of oocytes reaching the metaphase II stage and increased the percentage of degenerated oocytes compared with CS. Oocytes collected during HS also showed signs of cytoplasmic degeneration. After IVF, cleavage rate was lower (P < 0.01) for oocytes collected during HS, and the percentage of oocytes arrested at the two-cell stage was higher (P < 0.01) than oocytes IVF during CS. Oocytes matured during CS showed a higher (P < 0.01) blastocyst rate than those matured during HS. Also, COCs recovered in HS showed significant (P < 0.05) upregulation of HSP70 mRNA expression compared with those recovered in CS. For in vitro matured oocytes, CS down regulated the transcript abundance of ACTB and upregulated GAPDH and HSP70 mRNA levels compared with HS condition. In conclusion, HS could impair buffalo fertility by reducing the number of antral follicles and oocyte quality. In vitro maturation of buffalo oocytes during HS impairs their nuclear and cytoplasmic maturation, fertilization, and subsequent embryo development to the morula and blastocyst stages. This could be in part because of the altered gene expression found in COCs and in vitro matured oocytes.

Abstract
The primary objective of this study was to use macroscopic and histological features of corpora lutea with a cavity and anovulatory cystic ovarian structures, present in 90 pairs of abattoir-derived dairy cow ovaries, as the basis to clarify the nomenclature of ovarian structures. Excluding morphologically normal ovarian fol-licles (antrum < 2 cm, wall < 1 mm), there were 27 fluid-filled ovarian structures. Ovulatory structures > 16 mm in diameter were designated as Group A (cavity ≤ 10 mm and wall > 10 mm) or Group B (cavity > 10 mm and wall < 10 mm). The volume of luteal tissue was less (P < 0.05) in Group B than in Group A, whereas that of a solid corpus luteum (CL) was intermediate (least square means ± SEM: 72 ± 1.92, 11.22 ± 1.57 and 5.84 ± 1.92 cm3, respectively). There was a greater proportion (P < 0.05) of small luteal cells in Group B compared to a solid CL, whereas Group A was intermediate (58.6 ± 5.3, 37.4 ± 5.3 and 44.0 ± 4.4%, respectively). Connective tissue was thicker (P < 0.05) in Group B than in Group A (295.4 ± 46.9 vs. 153.9 ± 38.2 μm). Based on the above-mentioned characteristics and differences, Groups A and B were designated as a CL with a cavity and a cystic CL, respectively. Furthermore, there were three groups of anovulatory ovarian structures. Structures in Group C were termed persistent/anovulatory follicles (overall diameter and wall thickness ≤ 20 and 1-3 mm, respectively). Finally, Groups D and E were designated as a follicle-fibrous cyst and a follicle-luteinised cyst (based on histological structure) for anovulatory structures with an overall diameter and wall thickness of ≥ 20 and ≤ 3 mm, and ≥ 20 and ≥ 3 mm, respectively.
