Background. Oxidative stress is associated with infertility. This study was conducted to determine the effects of glutamate and aspartate on serum antioxidative enzymes, sex hormones, and genital inflammation in boars suffering from oxidative stress. Methods. Boars were randomly divided into 4 groups: the nonchallenged control (CON) and H2O2-challenged control (BD) groups were fed a basal diet supplemented with 2% alanine; the other two groups were fed the basal diet supplemented with 2% glutamate (GLU) or 2% aspartate (ASP)...

Mx1 (Myxovirus (Influenza virus) resistance 1, interferon-inducible protein p78) gene has been implicated in the resistance to a wide range of RNA viruses including influenza A in several species such as Sus scrofa. In the present study a 28-bp deletion in exon 14 of the Mx1 gene has been identified in Iberian domestic pigs but not in other domestic breeds neither in wild boars. The mutation produces a frameshift giving a protein with 6 amino acid substitutions and the extension of the C-terminal region with additional 20 amino acids with respect to the wild type MX1 protein...

Mycobacterium bovis is the causative agent of tuberculosis in farms, wildlife and causes sporadic disease in humans. Despite the high similitude in genome sequence between M. bovis strains, some strains like the wild boar 04-303 isolate show a highly virulent phenotype in animal models. Comparative studies will contribute to link protein expression with the virulence phenotype. In vitro, the 04-303 strain was more phagocytized by J774A.1 macrophages in comparison with 444 strain (a cow isolate with the same genotype) and BCG...

Energy produced by mitochondria via oxidative phosphorylation (OXPHOS) is essential for mammalian sperm motility. Mammalian mitochondrial DNA (mtDNA)-encoded proteins are subunits of the OXPHOS system. Paradoxically, there are less mitochondrial and mtDNA contents in motile sperm than less motile sperm. Here, mature boar sperm was used as a model to investigate the relationships between mtDNA content, mitochondrial activity, and sperm motility. Motile and less motile sperm were separated by centrifugation on a discontinuous percoll density gradient...

This study was designed to determine the degree and type of bacterial contamination in boar semen (79 ejaculates from Large White and Landrace boars) and its consequences for sperm quality during storage (27 extended semen samples, 16°C for five days) under practical conditions of artificial insemination (AI). The results revealed the presence of aerobic bacteria in 99% of the ejaculates (from 80 to 370 ×106 colony-forming units/mL). Most of the ejaculates contained two or three bacterial contaminants, while the Staphylococcus, Streptococcus, and Pseudomonas bacterial genera were most frequently isolated...

Boar taint is an unpleasant odour and flavour present in some entire male pigs that is due to the presence of androstenone and skatole. The aim of the study was to assess the sensitivity of 150 consumers to androstenone and to compare the acceptability and liking of meat from castrated and entire pigs, cooked with different cooking methods. Meat samples consisted of loins from castrated (CM) and entire male pigs (EM) with high levels of androstenone cooked by two cooking methods: sous-vide and fried/breaded with garlic and parsley...

This study aimed to determine whether heat stress (HS) could induce autophagy in immature boar Sertoli cells (SCs) and test whether HS-induced autophagy could regulate lactate secretion by SCs. Cultured immature boar SCs were incubated at 43 °C for 30 minutes. The ratio of LC3B-II to LC3B-I and the mRNA transcript levels of LC3B showed time-dependent changes 0 to 48 hours after HS treatment, which peaked at 24 hours and increased by 30.25% or 260%, respectively, compared with control SCs. The density of autolysosomes, which were labeled with a red dye, was higher at 24 hours than at any other time point...

Since the sequence of hepatitis E virus (HEV) was determined from a patient with enterically transmitted non-A, non-B hepatitis in 1989, similar sequences have been isolated from many different animals, including pigs, wild boars, deer, rabbits, bats, rats, chicken, and trout. All of these sequences have the same genomic organization, which contains open reading frames (ORFs) 1, 2, and 3, although their genomic sequences are variable. Some have proposed that they be classified as new family, Hepeviridae, which would be further divided into different genera and species according to their sequence variability...

Hepatitis E virus (HEV) is the causative agent of hepatitis E, a food- and water-borne disease. In developed countries, consumption of meats from pigs, wild boars and deer is a major source of infection. Although HEV and HEV-related viruses have been detected in many animal species, their zoonotic potential and prevalence has not been completely understood. To detect anti-HEV antibody in mammalian species, a simple enzyme-linked immunosorbent assay (ELISA) was established using extract from cells expressing HEV capsid protein and protein A/G as an antigen and a reagent for detection of antibody...

The Ryukyu wild boar (Sus scrofa riukiuanus) is an endemic, morphologically defined subspecies of the Eurasian wild boar (S. scrofa) found on five islands of the Ryukyu Archipelago (a group of small islands stretching from mainland Japan to Taiwan). Two hypothetical scenarios have been proposed regarding the origin of the current Ryukyu wild boar populations: 1) natural dispersal and 2) transportation and subsequent release by prehistoric humans. To test these two hypotheses, we compared the mitochondrial cytochrome b gene sequence (1140 base pairs) in 352 individual wild boar samples that included representatives of all five insular populations of the Ryukyu wild boar and populations of other conspecific subspecies in insular East and Southeast Asia and the Eurasian Continent...

The objective of this study was to evaluate relationships between common semen quality estimates including sperm motility, sperm morphology, spontaneous capacitation status and seminal plasma proteins and boar fertility using heterospermic inseminations and subsequent paternity testing. All boars (n=12) used in the study had excellent semen quality (≥70% normal sperm) that resulted in average farrowing rates and litter sizes of 88.9±0.7% and 11.7±0.1 pigs, respectively. Their ejaculates were combined to make heterospermic insemination doses in such a way that each boar was tested against all of his contemporaries...

To assess the status of research on wildlife diseases in the Republic of Korea (ROK) and to identify trends, knowledge gaps, and directions for future research, we reviewed epidemiologic publications on wildlife-associated diseases in the ROK. We identified a relatively small but rapidly increasing body of literature. The majority of publications were focused on public or livestock health and relatively few addressed wildlife health. Most studies that focused on human and livestock health were cross-sectional whereas wildlife health studies were mostly case reports...

Trichinellosis is one of the most widespread parasitic zoonoses. Trichinella Owen, 1835 nematodes are found in pigs, horses, and humans in the domestic cycle, and in many carnivores and omnivores in the sylvatic cycle, such as wild boars, red foxes, raccoon dogs, and wolves. Carnivores are known to be involved in the circulation of Trichinella nematodes and they act as a reservoir in the sylvatic environment. The aim of this study was to determine the occurrence of Trichinella spp. infection in red foxes in Poland...

Fixed-time post-cervical artificial insemination (FTAI) drastically reduces labour requirements and increases the use of boars with higher genetic merit. This study evaluated the efficiency of eCG administration combined with/without the GnRH agonist buserelin for the induction and synchronization of ovulation in weaned sows submitted to FTAI. The sows were allocated into three groups. In the control group, the first artificial insemination was performed at the onset of oestrus and repeated every 24 hr. In the eCG+GnRH group, sows received 600 IU eCG at weaning and buserelin (10 μg) after 86-89 hr of eCG, and in the GnRH group, sows received only buserelin after 86-89 hr of weaning...

Both feed efficiency and sow production are economically important traits in pig breeding. One challenge in a maternal line such as Norwegian Landrace is to breed for highly feed efficient fattening pigs and, at the same time, produce sows with high daily feed intake to maintain their BCS in multiple parities. The aim of this study was to estimate genetic correlations among novel feed efficiency measurements on Norwegian Landrace boars and piglet production, stayability, and body condition in Norwegian Landrace sows...

Toxoplasmosis is a major public health issue, due to the presence of Toxoplasma gondii, mainly in pork. The aim of this study was to determine the occurrence of T. gondii in pigs and wild boars bred in different production systems in the Czech Republic using ELISA and qPCR methods. Our results show that T. gondii infection is widespread in pigs and wild boars bred and slaughtered in the Czech Republic and that there is a higher exposure to T. gondii in backyard slaughter operations and organic pig farming, indicating a potential risk for meat consumption...

Trichinellosis is a rare parasitic zoonosis caused by Trichinella following ingestion of raw or undercooked meat containing Trichinella larvae. In the past five years, there has been a sharp decrease in human trichinellosis incidence rates in the European Union due to better practices in rearing domestic animals and control measures in slaughterhouses. In November 2014, a large outbreak of trichinellosis occurred in Belgium, related to the consumption of imported wild boar meat. After a swift local public health response, 16 cases were identified and diagnosed with trichinellosis...

Reactive oxygen and nitrogen species (ROS-RNS) are important defence substances involved in the immune response against pathogens. An excessive increase in ROS-RNS, however, can damage the organism causing oxidative stress (OS). The organism is able to neutralise OS by the production of antioxidant enzymes (AE); hence, tissue damage is the result of an imbalance between oxidant and antioxidant status. Though some work has been carried out in humans, there is a lack of information about the oxidant/antioxidant status in the presence of tuberculosis (TB) in wild reservoirs...
