Abstract
Photoperiod is an important environmental factor that influences seasonal reproduction behavior in birds. Birds translate photoperiodic information into neuroendocrine signals through deep brain photoreceptors (DBPs). OPN5 has been considered candidate DBPs involved in regulating seasonal reproduction in birds. We found that OPN5 could mediate light to regulate the follicle development in ducks. In this study, we further verified the effect of OPN5 on follicular development in Shan Partridge ducks by immunizing against the extracellular domain (ECD) of OPN5. We investigated the specific regulatory mechanism of photoperiod mediated by OPN5 on the reproductive activity of ducks. The trial randomly divided 120 Shan Partridge ducks into 3 groups with different treatments: the immunization of OPN5 group was done at d0, d15, d30, and d40 with 1 mL of vaccine containing OPN5 protein (thus containing 1, 1, 0.5, and 0.5 mg of OPN5-KLH protein), and the control group (CS and CL groups) was injected at the same time with the same dose of OPN5-uncontained blank vaccine. The group of CS (900 lux), OPN5 (600 lux), and CL (600 lux) lasted for 40 d in 12 L:12 D photoperiods, respectively. Then, the groups of CS, OPN5, and CL subsequently received 12 L:12 D, 12 L:12 D, and 17 L:7 D light treatments for 33 d, respectively. The ducks were caged in 3 constant rooms with the same feeding conditions for each group, free water, and limited feeding (150 g per duck each day). Duck serum and tissue samples were collected at d 40, d 62, and d 73 (n = 12). It was found that before prolonged light, the group of immunization (group OPN5) and the group of strong light intensity (group CS) were higher than the group of CL in egg production. Subsequent to prolonged light, the group CL in egg production rose about the same as the group immunization, while the strong light group (group CS) was lower. Group OPN5 increased the ovarian index of ducks, and both the immunization of group OPN5 and group CL (extended light) increased the thickness of the granular layer and promoted the secretion of E2, P4, LH, and PRL hormones. Compared with group CS, group CL and OPN5 increased the mRNA level and protein expression of OPN5 in the hypothalamus on d 62 and d 73 (P < 0.05). The gene or protein expression patterns of GnRH, TRH, TSHβ, DIO2, THRβ, VIP, and PRL were positively correlated with OPN5, whereas the gene expression patterns of GnIH and DIO3 were negatively correlated with OPN5. The results showed that immunization against OPN5 could activate the corresponding transmembrane receptors to promote the expression of OPN5, up-regulate the expression of TSHβ and DIO2, and then regulate the HPG axis-related genes to facilitate the follicular development of Shan Partridge ducks. In addition, in this experiment, prolonging the photoperiod or enhancing the light intensity could also enhance follicle development, but the effect was not as significant as immunizing against OPN5. Our results will offer beneficial data and more supportive shreds of evidence in favor of elucidating the role of OPN5 in relation to photoperiods and reproduction.

Abstract
The mitochondrial quality control system is crucial in maintaining cellular homeostasis during environmental stress. Granulosa cells are the main cells secreting steroid hormones, and mitochondria are the key organelles for steroid hormone synthesis. The impact of the mitochondrial quality control system on granulosa cells' steroid hormone synthesis and survival under heat stress is still unclear. Here, we showed that acute heat stress induces mitochondrial damage and significantly increases the number of mitophagy-like vesicles in the cytoplasm of duck ovary granulosa cells at the ultra-structural level. Meanwhile, we also found heat stress significantly increased mitochondrial fission and mitophagy-related protein expression levels both in vivo and in vitro. Furthermore, by confocal fluorescence analysis, we discovered that LC3 was distributed spot-like manner near the nucleus in the heat treatment group, and the LC3 spots and lysosomes were colocalized with Mito-Tracker in the heat treatment group. We further detected the mitophagy-related protein in the cytoplasm and mitochondria, respectively. Results showed that the PINK1 protein was significantly increased both in cytoplasm and mitochondria, while the LC3-Ⅱ/LC3-Ⅰ ratio increase only occurred in mitochondrial. In addition, the autophagy protein induced by acute heat treatment was effectively inhibited by the mitophagy inhibitor CysA. Finally, we demonstrated that the alteration of cellular mitophagy by siRNA interference with Drp1 and PINK1 inhibited the steroid synthesis of granulosa cells and increased cell apoptosis. Study provides strong evidence that the Drp1 regulated PINK1-dependent mitophagy pathway protects follicular granulosa cells from acute heat stress-induced injury.

Abstract
Gonadotropin-inhibitory hormone (GnIH) plays a crucial role in regulating reproduction in the hypothalamus of poultry and has been intensely investigated since its discovery. This study aimed to assess the effects of GnIH on testicular development, as well as on reproduction-related hormone release and gene expression levels in roosters. The administration of exogenous GnIH resulted in a significant reduction in testis weight, testis volume and semen quality (p < 0.05). Additionally, exogenous GnIH significantly up-regulates the expression of GnIH, and down-regulates the expression of PRL (p < 0.05). GnIH application also decreased the GnRH, vasoactive intestinal peptide (VIP) and luteinizing hormone β subunit(LHβ)gene expression levels. Meanwhile, by neutralizing the effects of endogenous GnIH through immunization, testicular development on day 150 in roosters was significantly promoted. Compared to the control condition, GnIH immunization significantly down-regulated the expression of the VIP and PRL genes (p < 0.05). In conclusion, we found that exogenous GnIH treatment inhibited testicular development, reduces PRL gene expression, and suppressed reproductive performance in roosters. Conversely, GnIH immunization down-regulated VIP and PRL genes, activates the reproductive system, and promotes the reproductive activity and testicular development of roosters.

Abstract
Lipopolysaccharide (LPS) reduces the reproductive performance of laying ducks, especially during the hot summer months. To study the underlying mechanisms, we investigated the effects of different LPS concentrations and heat on duck granulosa cell (GC) proliferation and steroid biosynthesis in vitro. We investigated GC proliferation, secretion, and activation of the MAPK pathway. The cell cycle results showed that LPS treatment alone did not significantly affect cell proliferation, whereas the mRNA expression levels of IGF2, IGFBP2, and CyclinD1 were downregulated and p27kip1 was significantly upregulated after 2000 ng/mL LPS treatment when compared to untreated cells. In steroid hormone synthesis, although LPS increased the expression of most steroid biosynthesis genes, it inhibited the expression of CYP11A1 at high LPS concentrations. High temperatures enhanced the inhibitory effect of LPS on the expression of proliferation-promoting genes. Heat significantly reduced CYP11A1 and CYP19A1 expression. In addition, the phosphorylation of P38 was significantly upregulated by high temperatures combined with LPS, whereas the phosphorylation of ERK1/2 and JNK was downregulated. The relative protein expression of Bax/BCL-2 was upregulated at high temperatures in combination with LPS. Heat treatment enhanced the inhibitory effects of LPS on the proliferation and hormone biosynthesis of duck GCs in vitro.

Abstract
Stocking density critically affects the growth and subsequent performance of animals in modern poultry production. This study investigated the effects of stocking density on ovarian development, ovarian maturation, and the mRNA expression of key genes in the reproductive axis during the rearing period of Shan-ma ducks. The experiments involved 180 healthy 7-wk-old Shan-ma ducks and randomly divided into low stocking density (LSD; n = 30, density = 5 birds/m2), medium stocking density (MSD; n = 60, density = 10 birds/m2) and high stocking density groups (HSD; n = 90, density = 15 birds/m2), for rearing. After examining ovarian development and measuring hormone levels in the plasma and expression levels of key regulatory genes in the reproductive axis at 19 wk of rearing, analysis of the gonad index analysis, reflecting stocking density, uncovered statistically significant differences. The gonad index of the LSD group was significantly higher than those of the MSD and HSD groups (P < 0.01), while no significant difference was observed between the MSD and HSD groups. pre-ovulatory follicles (POFs) and small yellow follicles (SYFs) development was only apparent in the LSD group, with the large white follicles (LWFs) number of this group being significantly higher than that of the MSD group (P < 0.05). The blood levels of E2 (estradiol), P4 (progesterone), and T (testosterone) were significantly higher in the LSD group than in the MSD and HSD groups (P < 0.05 or 0.01). Also, the levels of both P4 and T were significantly higher in the MSD group than in the HSD group (P < 0.01). The gene expression levels of GnRHR, FSH, AMHR, and FSHR were significantly increased in the LSD group compared to the MSD and HSD groups (P < 0.05 or 0.01), while the expression levels of GnIHR and GDF9 were significantly decreased in the LSD and MSD groups compared to the HSD group (P < 0.05 or 0.01). Steroid biosynthesis pathway genes such as StAR, CYP11A1, 3β-HSD, CYP19A1, and BMP15 were significantly downregulated at greater stocking densities (P < 0.05 or 0.01). Likewise, the protein expression of StAR, 3β-HSD, and CYP19A1 was also significantly decreased (P < 0.05 or 0.01). These results demonstrate that both medium and high stocking densities suppressed the expression of the key reproduction-promoting factors, while the expression level of the key reproductive inhibitory factors was enhanced. Therefore, rates of ovarian development and maturation could be reduced by a high stocking density leading to a delay in reproduction performance during the rearing period of Shan-ma ducks.

Abstract
Resveratrol, a natural antioxidant, anti-inflammatory plant extract, was found to have a protective effect in poultry subjected to heat stress. In this study, we strove to characterize resveratrol on intestinal of duck exposed to acute heat stress and investigate the underlying mechanism. A total of 120 Shan-ma ducks (60 days old) were randomly divided into 2 groups. The control group was fed a basal diet, and the resveratrol group was fed a basal diet supplemented with 400 mg/kg resveratrol. Animals in 2 groups were kept at a temperature of 24°C ± 2°C for 15 d. Then, animals of both groups were placed in an artificial climate room at 39°C. Twelve ducks of each group were sacrificed for sampling at 0, 30, and 60 min, respectively. Results indicated that resveratrol increased the ratio of villus height to crypt depth, increased the number of goblet cells, and reduced the histopathological damage of jejunum caused by acute heat stress. Furthermore, the gene expression of heat shock proteins (HSP60, HSP70, and HSP90) and tight junction proteins (CLDN1 and OCLN) was significantly increased in the resveratrol group compared to that in the control groups. Simultaneously, resveratrol significantly activated the SIRT1-NRF1/NRF2 signaling pathways, improved ATP level of jejunum, and increased SOD and CAT antioxidant enzymes activities. In addition, we found that the NF-κB/NLRP3 inflammasome signaling pathways were repressed under acute heat stress. Meanwhile, supplement resveratrol further inhibited the NLRP3 inflammasome pathway, decreased protein level of NLRP3 and caspase1 p20, reduced the secretion of IL-1β. Taken together, our results indicate that resveratrol against the oxidative damage and inflammation injury in duck jejunum induced by heat stress via active SIRT1 signaling pathways.

Abstract
Granulosa cells (GCs) play an important role in the development of follicles. In this study, we investigate the impact of heat stress at 41°C and 43°C on duck GCs' proliferation and steroids secretion. And, the transcriptomic responses to heat treatment were examined using RNA-sequencing analysis. Digital gene expression profiling was used to screen and identify differentially expressed genes (fold change ≥ 2 and Q value < 0.05). Further, the differential expression genes (DEGs) were classified into GO categories and KEGG pathways. The results show that duck GCs blocked in the G1 phase were increased on exposure to heat stress. Meanwhile, the expression of proliferative genes, which were essential for the transition from G1 to S phase, was inhibited. At the same time, heat stress inhibited the estradiol synthesis of GCs by decreasing CYP11A1 and CYP19A1 gene expression. A total of 241 DEGs including 181 upregulated and 60 downregulated ones were identified. Transcriptome result shows that heat shock protein and CXC chemokines gene were significantly activated during heat stress. While collagenases (MMP1 and MMP13) and strome lysins (MMP3) were downregulated. And, the hedgehog signaling pathway may be a prosurvival adaptive response under heat stress. These results offer a basis for better understanding the molecular mechanism underlying lay-eggs-less in ducks under heat stress.

Abstract
Outbreaks of short beak and dwarfism syndrome (SBDS), caused by a novel goose parvovirus (NGPV), have occurred in China since 2015. This rapidly spreading, infectious disease affects ducks in particular, with a high morbidity and low mortality rate, causing huge economic losses. This study analyzed the evolution of NGPV isolated from Jing-Xi partridge duck with SBDS in South China. Complete genome sequences of the NGPV strains GDQY1802 and GDSG1901 were homologous with other GPV/NGPV and Muscovy duck parvovirus (MDPV) strains. Phylogenetic analysis showed that the NGPV isolated from mainland China was related to the Taiwan 82-0321v strain of GPV. In contrast to 82-0321v and the SDLC01 strain, which was first isolated from China, the two isolates showed no deletions in the inverted terminal repeat (ITR) region. Further, in these isolates, 24 amino acid sites of the replication protein were different compared to that of GPV live vaccine strain 82-0321v, and 12 sites were unique across all NGPV isolates. These isolates also showed differences in 17 amino acid sites of the capsid protein from that of 82-0321v, two of which were the same as those in MDPV. Recombination analysis identified the major parents of GDSG1901 and GDQY1802 as the NGPV-GD and NGPV-Hun18 strains, and the minor parents as the classical GPV 06-0329 and GPV LH strains, respectively. GDQY1802 and GDSG1901 are recombinant GPV-related parvovirus isolated from domesticated partridge duck. Recombination is evident in the evolution of NGPV, and as such, the use of live attenuated vaccines for NGPV requires further study.

Abstract
This study was performed to evaluate effects of Armillariella tabescens (A. tabescens) on the growth performance and intestinal immune response and microflora in early-weaned pigs when used as feed additive. A. tabescens mycelia were added to basal diets at concentrations of 0%, 0.1%, 0.3% or 0.9% (w/w). A total of 144 commercial cross-bred piglets were randomly allocated to one of these four diets and fed for 30 days. The growth performance of early-weaned piglets displayed improvement with diets containing 0.1% and 0.3% dried mycelia powder from A. tabescens. Supplementing with 0.1% or 0.3% A. tabescens mycelia induced a 2.6- and three-fold increase in secretory immunoglobulin A (sIgA) content in the jejunal mucosa, respectively, but had only a marginal effect on sIgA in the ileal mucosa. Expression of interleukin-2, interferon-γ, and tumor necrosis factor-α in the jejunal mucosa were elevated with A. tabescens mycelia administration. Increased amounts of Lactobacillus spp. and Bifidobacterium spp. in the jejunum, and decreased amounts of Escherichia coli in the jejunum and ileum were observed with the administration of A. tabescens-containing diets. This study demonstrated that A. tabescens had beneficial effects on the growth performance and intestinal microflora of early-weaned pigs.

Abstract
In order to explore the feasibility of cryopreserving primordial follicles in attaining their developmental competence following freezing and thawing, ovaries from newborn mice were cryopreserved and the thawed ovaries were xenografted into kidney capsules of adult female mice. Ovaries were isolated from newborn B6C2F(1) female mice, infiltrated by Leibovitz 15 (L-15) medium containing 10% (V/V) fetal bovine serum (FBS) and 1.5 mol/L dimethylsulfoxide (DMSO), and then packed into 0.25 ml plastic straws. The ovaries contained in straws were frozen under nitrogen vapour at -40 degrees C in Cryocell 1200 programmable freezer, and stored in liquid nitrogen for periods ranging from 1 week to 6 months. Upon thawing, the straws were dipped into room temperature water for 10~20 s, after which the ovaries were collected and washed in L-15 buffer containing 10% (V/V) FBS without DMSO to remove cryoprotectant. The thawed ovaries were transplanted into kidney capsules of 8~12-week old adult B6C2F(1) female recipient mice by two protocols, with either 1 or 2 ovaries in each capsule. Upon withdrawal after at least 14 d of transplantation, only 45.00% (72/160) of the ovaries were recovered from 40 recipients transplanted with 2 ovaries in each capsule, compared to 82.50% (33/40) in 20 recipients with only 1 ovary in each capsule. The grafted ovaries exhibited similar follicular developmental progression to that of natural ovaries. There were antral follicles present in the transplanted ovaries on day 14, whose number increased more substantially on day 19 after transplantation. Following stimulation of the recipient mice with 10 IU PMSG on day 19 after xenografting, follicles further developed to preovulatory stage with appearance of cumulus oocytes and enlarged antrum. Oocytes from these fully grown antral follicles were collected and matured in vitro in modified essential medium-alpha (MEMalpha). After 16~17 h of culture, 40.90% of the oocytes exhibited germinal vesicle breakdown (GVBD) and among which 89.02% proceeded to the metaphase II (MII) stage as indicated by exclusion of the first polar body. The remaining oocytes were further cultured and 50.83% of which initiated GVBD by 20~21 h of culture, but only 21.40% of which proceeded to MII. The above results demonstrated that the primordial follicles in newborn mouse ovaries were capable of sustaining freezing and thawing, and reinitiating development following xenograft into kidney capsule in adult recipient female mice. Production of mature oocytes from such re-developed follicles following gonadotrophin priming and the subsequent oocyte in vitro maturation implied immense prospect of application of this method to preserve female germ cells, conserve endangered species, establish animal gene stock, and utilize oocytes in assisted reproductive techniques.
