Abstract
In an effort to enhance reproductive management and reduce non-productive periods in swine breeding, this study presents a novel, non-invasive metabolomics approach for the identification of early pregnancy biomarkers in sows. Utilizing an untargeted metabolomics approach with mass spectrometry analysis, we examined saliva samples from pregnant (n = 6) and non-pregnant control sows (n = 6, artificially inseminated with non-viable sperm). Our analysis revealed 286 differentially expressed metabolites, with 152 being up-regulated and 134 down-regulated in the pregnant group. Among these, three metabolites, namely Hyodeoxycholic acid, 2'-deoxyguanosine, and Thymidine, emerged as potential early pregnancy biomarkers. These biomarkers were further evaluated using targeted LC-MS/MS quantification and qualification, accompanied by ROC curve analysis. The study confirmed Hyodeoxycholic acid and 2'-deoxyguanosine as promising biomarkers for early pregnancy detection, offering potential for future implementation in swine production environments. This research establishes a robust theoretical foundation for the development of innovative molecular diagnostic techniques and explores new avenues for molecular genetic breeding and non-invasive diagnostics, ultimately enhancing fertility and productivity in sow herds.

Abstract
This review addresses the influence of homebox A10/a10 (HOXA/Hoxa10) gene on reproductive tract anatomy and functional fertility in mammalian species, and discusses major endocrine and environmental regulators of HOXA/Hoxa10 expression. Female reproductive efficiency or success is a function of several factors including the ovulation and fertilization rate, and uterine receptivity. A family of HOX/Hox genes establishes the segmental identity of the reproductive tract during embryogenesis and retains its physiological plasticity in sexually mature animals and humans. In particular, the HOXA/Hoxa10 gene is an intrinsic component of implantation, decidualization, and immunomodulation in the adult uterus. It was, therefore, suggested that knowledge of HOXA/Hoxa10 regulation might be essential in navigating molecular mechanisms with the aim of enhancing female reproductive potential. However, a recent study in pigs revealed a lack of associations between endometrial HOXA10 expression and reproductive tract morphology, and very poor correlations with sows' fertility metrics. Retinoic acid mainly regulates 3' HOX/Hox paralogs but may also modify the expression of downstream HOX/Hox genes, including HOXA/Hoxa10. Sex steroids directly regulate HOXA/Hoxa10 expression. The vitamin D receptor pathway modulates HOXA/Hoxa10 expression in the adult reproductive tract. Lastly, endocrine disruptors such as diethylstilbestrol, methoxychlor, bisphenol A, and isoflavones were shown to alter HOXA/Hoxa10 expression, thus affecting reproductive competence of the female.

Correlates of reproductive tract anatomy and uterine histomorphometrics with fertility in swine. Theriogenology 2021; 165:44-51. [PMID: 33611173 DOI: 10.1016/j.theriogenology.2021.02.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 02/03/2021] [Accepted: 02/07/2021] [Indexed: 11/25/2022]
Abstract
Economic potential of the swine industry hinges upon the reproductive performance of sows, which may be enhanced by improving uterine capacity, a component trait of litter size and piglet productivity. Previous attempts at characterizing morphological traits indicative of high uterine volume have not been completely successful, resulting in the continued need for a reliable method of predicting reproductive value to improve production efficiency of the sow. Hence, the main objective of this study was to scrutinize macro- and micro-morphology of the sow's reproductive tract for quantitative correlations with fertility indices. Reproductive records from Polish Landrace × Polish Large White sows were used to examine the associations between fertility and ovarian/uterine morphology (n = 34) or uterine histomorphometry (n = 10). Several measures related to the ovary, including right and left ovarian weight (r = 0.50, p = 0.005 and r = 0.49, p = 0.006, respectively), were positively correlated with the litter size, while left ovarian number of corpora lutea (r = -0.38, p = 0.04) was negatively correlated with the mean litter size. Analysis of histomorphological characteristics of the uterine wall collected during the luteal phase of the estrous cycle revealed correlations between mean litter size and myometrial vascular content (r = 0.75, p = 0.03), the proportion of myometrial stroma (r = -0.68, p = 0.03), and the variability of endometrial thickness (r = -0.72, p = 0.02) in sows. Eight ovarian, vaginal and uterine characteristics were significantly correlated with mean lifetime numbers of live born and stillborn piglets/litter or the last litter size before slaughter. In conclusion, several anatomical and histomorphological metrics that relate to reproductive performance of swine may be used to inform production protocols and as a tool for selection of elite breeding sows, warranting future research into non-invasive or minimally invasive techniques for obtaining such measures.

Administration of a single dose of 300 IU of human chorionic gonadotropin seven days after the onset of estrus improves pregnancy rate in dairy goats by an unknown mechanism. Domest Anim Endocrinol 2021; 74:106579. [PMID: 33161234 DOI: 10.1016/j.domaniend.2020.106579] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 10/01/2020] [Accepted: 10/02/2020] [Indexed: 12/17/2022]
Abstract
This study examined the effects of exogenous hCG administration on ovarian function and pregnancy rates in estrous-induced dairy goats during the transition into the breeding season. Eighty-six Toggenburg does received 60 mg of medroxyprogesterone acetate intravaginal sponge for 6 d plus 200 IU of equine chorionic gonadotropin and 30 μg of d-cloprostenol i.m. 24 h before sponge removal, and were then bred for 96 h. Seven days (D7) after first mating the does received either 1 mL of saline (the control group, n = 43) or 300 IU of hCG (the hCG-treated group, n = 43) i.m. Transrectal ovarian ultrasonography (B-mode and color Doppler) was performed on D7, D13, D17, and D21 and ultrasonographic pregnancy detection on D30. Pregnancy rate was higher (P < 0.05) in hCG-treated goats (90.7%; 39/43) than that in control animals (74.4%; 32/43). Accessory luteal structures (ALSs) were detected in 46.5% (20/43) of hCG-treated does. All hCG-treated does that had ALSs and 82.6% of goats without ALS post-treatment remained pregnant. The total luteal area increased (P < 0.05) from D7 to D13 in pregnant animals of both groups, whereas mean vascular area declined (P < 0.05) by D21 in all nonpregnant does. Serum progesterone concentrations increased (P < 0.05) on D21 in pregnant goats of both groups, but they were related to changes in luteal tissue content only in control does throughout the present study. Mean daily numbers of small- and medium-sized antral follicles decreased (P < 0.05) only in pregnant animals of both groups with a decline in medium follicle numbers occurring earlier in hCG-treated (D13) compared with control does (D17). To summarize, a single dose of hCG given on D7 after estrus was followed by a decrease in the number of medium-sized antral follicles in gestating hCG-treated does, induced the formation of ALSs in ~47% of all hCG-treated does, and significantly increased the pregnancy rate in estrous-induced Toggenburg goats in the transition to the breeding season.
