Prodanov-Radulovic, Jasna, Radoslav Dosen, Igor Stojanov, Ivan Pusic, Milica Zivkov-Balos y Radomir Ratajac. "Influence of mycotoxin zearalenone on the swine reproductive failure". Zbornik Matice srpske za prirodne nauke, n.º 124 (2013): 121–29. http://dx.doi.org/10.2298/zmspn1324121p.
Reproductive failure in swine is often a difficult diagnostic problem. If diagnoses of infectious disease or management related problems are not obtained, feed quality and safety may be questioned. Mycotoxins are often present in swine feed in the amount that can have detrimental impact on production and reproduction. Problems are expressed only as alterations of the reproductive cycle, reduced feed intake, slow growth or impaired feed efficiency. In Serbia, generally speaking, high concentrations of mycotoxins were noticed, especially mycotoxin zearalenone. High presence of zearalenone in swine feed is probably due to climatic influence and should be monitored constantly. This paper includes field observations regarding the influence of moldy feed containing mycotoxin zearalenone on the occurrence of the reproductive failure in swine breeding categories (sows, gilts and boars). The material for this research was obtained from four swine farms where certain reproductive disorders and health problems in breeding animals were detected. Depending on the specificity of each evaluated case and available material, the applied research methods included: anamnestic and clinical evaluation, pathomorphological examination, standard laboratory testing for detection of aerobic and anaerobic bacteria, and microbiological feed testing, in order to examine the presence of fungi and mycotoxins by applying the method of thin layer chromatography. On the basis of the obtained results, it could be concluded that mycotoxin zearalenone was detected in all examined feed samples. The presence of mycotoxin in feed was directly related to the reproductive failures in the examined swine categories (vulvovaginitis, endometritis, rebreeding, infertility). Swine reproduction represents the base for intensive swine production. The presence of mycotoxins in swine feed have influence on the reproduction and health status of pigs and under certain conditions may significantly disturb the production process.

Petrujkic, Tihomir. "New biotechnological procedures in swine reproduction". Veterinarski glasnik 56, n.º 1-2 (2002): 111–23. http://dx.doi.org/10.2298/vetgl0202111p.
New biotechnological procedures and the use of hormones in swine breeding are aimed at increasing the number of piglets in the litter. In small herds and groups, selected sows with 16 mammary complexes (tits) can yield up to 32 piglets, or porkers, per year per sow. In order to achieve such reproduction results, special, individual stalls for sow deliveries are used, in addition to biotechnological methods, with a warm core and floor heating, phased diet and clean facilities. The ovulation value in swine is determined by their genetic and paragenetic effects, and it is often provoked and increased with injections and preparations for superovulation. However, the results vary, since any administration of hormone injecions can reduce the reproductive cycle, shorten the duration of estrus, or disrupt the work of ovaries and create cystic follicles. The use of follicle-stimulating hormones in quantities up to 1000 IU per animal for the induction and synchronization of estrus has become customary for sows and gilts, as well as the use of prostaglandins, the use of GnRH for increasing ovulation in swine and increasing the number of follicles >4 mm in diameter in the implementation of new biotechnologies in swine breeding, increases the number of ovulations and fertility in swine. In this way, reproduction is raised to the highest possible level, and artificial insemination of sows has 12 separate rules which enable better and more successful artificial insemination of sows.

This review studies several factors affecting the reproductive performance of swine chiefly focusing on sow-related factors, which have significant economic importance. A sow’s productivity is determined by different reproductive attributes, including litter size, litter weight at weaning, farrowing rate, the return of oestrus, and many more. The increase in number of pigs born alive and weaned piglets per sow is an aim for swine husbandry.Various factors such as parity, housing, feed, gestation length, season, and temperature are considered in this paper. Sows of differing parities have performed differently.The performance was influenced by various feeding systems, comfort, spacing, aggressiveness, and disease transmission in the housing system. Feeding intake and nutrition uptake are directly connected with milk secretion as well as other traits. Season and temperature are correlated with feeding intake, time of puberty, hormonal production, and seasonal infertility.Scientists are globally working for productive breeds. However, the rearing of swine will necessitate the consideration of different non-genetic factors of their reproduction from an economicpoint of view.The goal of this study is to understand non-genetic factors that affect sow reproduction and to advise swine farmers on how to create a better environment for swine to improve productivity.

Problems in the reproduction of pigs may be the result of interaction of various factors, both infectious and non-infectious. Among the infectious agents, the greatest economic losses are caused by viral infection of pregnant gilts and sows. In the present study the most important pathogens causing reproductive disorders in pigs, including parvovirus (PPV), porcine reproductive and respiratory syndrome (PRRSV), swine influenza virus (SIV), porcine circovirus type 2 (PCV2), enteroviruses, encephalitis virus (EMCV), Aujeszky's disease virus (ADV), classical swine fever virus (CSFV), Leptospira spp., Brucella suis and Erysipelotrix rhusiopathiae are characterized. So far, three possible ways of natural infection of the embryo or fetus are identified: via placenta, through the cervical canal, and by infection of the egg cell. The consequences of infection of pregnant females depend on the species of the virus, the gestation period, wherein there is an infection and immune status of pregnant females. The most common changes included: embryo death, resorption of embryos, mummification of fetuses, malformations, abortions, birth of dead or very weak piglets. Because of the importance of the reproduction sector for the competitive production of pigs, the monitoring of the health status of breeding stock, including compliance with all biosecurity rules and vaccination schedules, should be strictly respected by veterinarians taking care of pig breeding herds
Viral infections hold an important place among factors which can cause disorders in swine reproduction. Infections with the porcine parvovirus (PPV) are present in all herds. In the past four years, 70-77% seropositive animals have been registered in herds of the industrial type. There are increasing reports about disorders in swine reproduction, both from individual breeders and mini farmers, caused by parvoviral infections. The objective of this work is to demonstrate the latest knowledge on epizootiology, pathogenesis, diagnostics, and prophylaxis of this diseases.

PRLR gene has been studied as a candidate gene for litter size in swine because of prolactin biological functions and their association with reproduction. Prolactin receptor gene is mapped on porcine chromosome 16. The established PCR-RFLP polymorphism at PRLR locus demonstrated the presence of two alleles, А and В and three genotypes АА, АВ and ВВ. There were found different allele and genotype frequencies in different pig populations with variation of the effects of PRLR genotypes on litter traits. Additional studies should be done in specific breeds and populations to evaluate the association of existing PRLR locus polymorphism with reproductive traits before application of marker-assisted selection in these populations.

Belstra, Brad A. "483 Current Knowledge Gaps in Swine Reproduction". Journal of Animal Science 99, Supplement_3 (8 de octubre de 2021): 212–13. http://dx.doi.org/10.1093/jas/skab235.386.
Abstract Identifying swine reproduction research opportunities, especially those that add value by addressing industry challenges and leveraging assisted reproductive technologies (ART) will be the focus of this talk. ART and genetic selection to increase pork production efficiency have been intertwined since the use of artificial insemination (AI) became widely adopted 30 years ago. Tremendous efficiency gains have been made in part by increasing litter size which is nearly 6 to 7 pigs larger today than it was in 1990. The increased farrowing duration and stillbirths, and decreased piglet birth weight, colostrum intake, and survival to weaning that has been associated with these larger litters are prime targets to be ameliorated with sow and pig management solutions. There is also clear evidence that pigs from smaller litters have the advantage of superior reproductive performance compared to those from larger litters. Thus, litter size and pre-weaning growth may need to be managed, or at least taken into account, to select the best boars and gilts for breeding stock and replacements. Any other accurate, early indicators of boar and gilt puberty, fertility, and lifetime productivity could add significant value. The seasonal fluctuation in fertility that has plagued pig production is costly and may be smoothed out by strategies that mitigate heat stress and improve health. Another opportunity to improve both pig and sow welfare may be intermittent suckling and induction of a fertile estrus and ovulation for breeding during lactation. Even more genetic and pig growth value could be added via AI with sex-sorted semen, if methods to better estimate boar fertility, deliver increased sperm quality, and more precisely synchronize or predict ovulation can be found to reduce the number of sperm required per female. Existing and evolving ART will synergize with genomics and gene editing technologies to unlock new levels of production efficiency.

Austin, Adrian G. y Jeff G. Wiegert. "155 Opportunities and Challenges of Teaching Laboratory Content of a Swine Discipline-focused Course with Limited Swine Access". Journal of Animal Science 99, Supplement_1 (1 de mayo de 2021): 143–44. http://dx.doi.org/10.1093/jas/skab054.244.
Abstract In spring semester, 2020, ANSC 412: Swine Production and Management (4 credits, lecture and laboratory) was offered in the Department of Animal Science at Texas A&M University following a period of nonappearance in the curriculum. Simultaneously, planned renovation of the campus swine teaching farm required depopulation of the existing herd. Hence, animal access for course laboratories was restricted for the 2020 spring and fall semesters. The objective is to present strategies to achieve effective laboratory learning objectives with limited livestock access. Average course enrollment in 2020 spring and fall semesters was 11 students of junior and senior standing. The course laboratory was held for two hours weekly for fifteen weeks. COVID-19 interruption of the spring semester, and arrival of pigs to the campus swine teaching farm in the fall semester, necessitated creation of ten equivalent laboratory sessions per semester. Example laboratory sessions include: panels with swine industry professionals, Pork Quality Assurance version 4.0 certification, virtual farm tours, evaluating genetic merit with National Swine Registry Swine Testing and Genetic Evaluation System EPD data and indexes, understanding least-cost diet formulation with diet formulation software, creating and implementing a Secure Pork Supply enhanced biosecurity plan for the campus swine farm, and multiple case study models of troubleshooting reproductive deficiencies with the US Pork Center of Excellence National Swine Reproduction Guide. Laboratory session execution facilitated achievement of TAMU Department of Animal Science programmatic learning outcomes, specifically: understanding animal breeding programs, animal husbandry, reproductive management, and nutrient conversion, and assessing business models and application of animal management strategies. In future semesters with unrestricted swine access for teaching, live-animal handling will be emphasized in the syllabus, yet preservation of effective classroom-based laboratories will persist. These methods have value for instructors operating without campus swine resources and those whose laboratory content has been impacted by COVID-19 disruption.
Rhéaume, John. "Manganese nutrition in rat and swine reproduction". Thesis, McGill University, 1990. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=74293.
Experiments were conducted with littermate gilts maintained in stainless steel metabolism cages within environmentally controlled rooms and consuming a corn-soybean meal based diet. The objectives of these studies were to investigate the impact of different dietary levels of manganese (Mn) and/or stage of the reproductive cycle on mineral metabolism and more specifically Mn metabolism in primigravid gilts and rats. Nutritional status was assessed using conventional balance studies, the analyses of physiological fluids (urine, plasma, colostrum, milk), tissues of the dam and offspring, and by a radioisotope dilution-balance technique. Trace element retention in the first-litter gilt was not significantly altered by dietary Mn restriction (11 $ mu$g/g DM) or by different stages of the reproductive cycle. In contrast, among the macro elements, phosphorus and perhaps calcium retention were improved in late gestation, whereas magnesium and nitrogen retention were unchanged. The weight of the litter at birth from dams consuming the low Mn (LMn) diet was significantly less than high Mn (HMn) gilts (96 $ mu$g/g DM). The Mn concentration in the liver and kidney of HMn gilts were significantly higher than in LMn gilts at the end of lactation. Likewise, the bones from HMn piglets contained higher concentrations of Mn at birth, and the liver and kidney concentrations were greater at weaning. Dietary Mn intake did not influence the rate of $ sp{54}$Mn excretion by the gilt during late gestation. The endogenous fecal Mn component was of similar magnitude, averaging 0.26 and 0.21 mg/d for the HMn and LMn gilts, respectively. However, the endogenous contribution to total fecal Mn was almost 8 fold different, representing 0.12% and 0.82% of total fecal Mn for the HMn and LMn gilts, respectively. The biological half-life of Mn in the body of the gilt was not influenced by dietary Mn within the intake range of 26 to 210 mg/d and averaged 54 days. The turnover rate (TR) of Mn was es

The purpose of this study was to investigate the effect of intrauterine position and its possibly resultant steroid differential on conceptus growth and steroid content in allantoic and amniotic fluid of pigs. six conceptus variables (placental weight, placental length, fetal weight, fetal length, allantoic fluid volume and amniotic fluid volume) and seven steroids (progesterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulfate, testosterone, estrone and estrone sulfate) were evaluated. Four fetal positions were studied: females between females (f2F), females between males (fOF) , males between females (m2F) and males between males (mOF).
Fetuses examined from ovariectomized (OVX) pregnenolone (PS)-treated gilts showed differences in placental
weight, allantoic fluid estrone and androstenedione content and amniotic fluid androstenedione content as a result of intrauterine position. Fetuses from OVX gilts treated with either medroxyprogesterone acetate (MPA) I or progesterone (P4) showed differences in placental length due to intrauterine position. Allantoic and amniotic fluid content of any of the steroids studied from OVX MPA- and P4-treated gilts was not altered as a result of intrauterine position. Intrauterine position appears to have a definite influence on conceptus development and possibly on steroid content. However, discrepancies' of results among trials possibly as a result of differences in type and amount of exogenous precursor enable us to draw stronger conclusions on the intrauterine position effect.

The present studies were conducted to gain a better understanding of the effects of pregnenolone (P₅), human chorionic gonadotropin (hCG) and 3' 5', cyclic adenosine monophosphate ( cAMP) on porcine placental and endometrial production of progesterone (P₄), testosterone (T) and estrone (E₁) at 30, 60 and 90 days of gestation. Duplicate 300 mg samples of placenta, endometrium or both (co-incubation) were incubated in medium199 containing either no P₅, P₅, P₅ + hCG or P₅ + cAMP for either zero (control), .5, 1 or 2 h.
The first study compared P₄ and E₁ production with or without addition of P₅. At d 30, 60 and 90, respectively, P₄ production (ng/g) increased significantly in the presence (vs absence) of P₅ in the incubation medium of placental (13.2 vs 7.5, 73.9 vs 42.7, 137.4 vs 113.5, respectively) coincubation (14.5 vs 10.0, 33.6 vs 22.3, 77.9 vs 49.4, respectively) and endometrial (16.0 vs 13.3, 23.0 vs 16.0, 17.1 vs 6.7, respectively) tissue. Presence of P₅ increased E₁ production in d 60 (1.3 vs .7 ng/g) and d 90 (51.7 vs 34.6 ng/g) placental tissue and d 90 endometrial tissue (9.8 vs 8.0 ng/g).
In a second study, P₅ + cAMP increased (vs P₅ alone) P₄ in placental tissue at d 30 (11.6 vs 8.7 ng/g) and coincubation tissue at d 90 (103.7 vs 75.3 ng/g). Cyclic AMP stimulated increased P₄ synthesis ( vs P₅ alone), throughout the incubation period in d 60 and d 90 tissue. E₁ production by endometrial tissue at d 30 (4.1 vs 2.9 ng/g), and placental tissue at d 60 ( 1. 2 vs . 9 ng/g). Presence of hCG in the incubation medium had no overall effect on either P₄ or E₁ accumulation. Only trace amounts of T were detected in either study, suggesting rapid aromatization of C₁₉ steroids to estrogens. M.S.

Thesis (M. Tech. Agriculture) -- Central University of Technology, Free state, 2012 Frozen-thawed boar sperm has the potential to impact the future of the swine industry. The objectives of the study were to characterise semen of Kolbroek and Large White boars, find a suitable holding temperature and extender, determine the effect of breed and pregnancy rate following artificial insemination by frozen-thawed boar semen. A total of eight boars and 33 sows were used in this study. The 120 ejaculates were collected from each individual Kolbroek and Large White boars with the gloved-hand technique. Macroscopic and microscopic sperm characteristics were recorded. The bodyweight of Kolbroek (154.7 kg) was significantly lower compared to Large White (189.9 kg) boar. However, no significant differences were observed in Kolbroek and Large White boar semen volume (140 and 170 ml), sperm concentration (0.727 and 0.761 x 109 sperm/ml), and total sperm motility (95 and 91%). A positive correlation existed between bodyweight and semen volume of Kolbroek (r= 0.22) and Large White (r= 0.26). Conversely, the bodyweight of Large White was positively correlated to sperm concentration of Large White (r= 0.37) but negatively correlated to Kolbroek (r= -0.66). Storage time and temperature did not affect Large White boar sperm motility rate. However, Kolbroek sperm total motility rate (61.0%) was affected at 25°C after 24 hours. The highest total sperm motility rate was observed for semen diluted with Tris-based extender (74.1%) in Kolbroek boars at 48 hours of storage. Large White boar semen diluted with BTS (62.9%), Kobidil+ (69.3%) and Tris (65.1%) showed significantly higher sperm motility rate at 48 hours of storage, compared to Citrate (27.6%) extender. Cryopreservation significantly reduced sperm motility rate for Kolbroek (30.2%) and Large White (24.0%) boars. However, a high pregnancy rate was recorded in both sows of inseminated with raw diluted (100% vs. 81.3%) and frozen-thawed (50% vs. 50%) semen of Kolbroek and Large White boars. In conclusion, the bodyweight of Kolbroek and Large White boar was positively correlated with ejaculated semen volume. Kolbroek and Large White boar sperm stored at 18°C for 24 hours maintained the acceptable sperm motility rate. Kolbroek boar semen diluted with Tris-based extender maintained high sperm motility rate. Cryopreservation significantly reduced sperm motility rate regardless of breed; however, pregnancy rate from frozen-thawed semen was high for Kolbroek (50%) and Large White (50%) even though the frozen-thawed fertility was low.
