This study evaluated effects of diet supplementation with omega-3 polyunsaturated fatty acids (PUFA) from microalgae on boar sperm quality. Two groups of boars (n = 3 each) were fed during 75 days either a commercial diet (control), or the same diet supplemented with omega-3 PUFA from the heterotrophic microalgae Schizochytrium sp. (120 g/kg). Sixteen ejaculates were collected per boar. Some sperm kinetics parameters were inferior for supplemented than for control boars (p < .05): distance average path; distance in both curved and straight line; velocity average path, velocity in both curved and straight line; and amplitude of lateral head displacement...

The present study was conducted to determine the effect of flaxseed meal and oat hulls supplementation on growth performance, apparent total tract digestibility (ATTD) of fat, serum lipids, and concentrations of VFA, bile acids (BA), and neutral sterols (NS) in digesta and feces in growing pigs. Forty-eight Genesus [(Duroc boar × Yorkshire-Landrace sows] barrows (25.0 ± 0.32 kg initial BW) were housed in pairs. Pigs were assigned to 1 of the 3 corn-soybean meal-based diets-a basal corn-soybean meal-containing diet (control), a flaxseed meal-containing diet (FM), or an oat hulls-containing diet (OH)-in a completely randomized design...

Azaperone treatment can control aggression and decrease stress due to weaning, re-grouping and hierarchical fighting of gilts and sows. However, the effects of this butyrophenone neuroleptic and sedative administered at weaning on pig reproductive function are poorly characterized. In this year-long study, a total of 619 cross-bred sows (Polish Large White×Polish Landrace) kept on a commercial farm received an i.m. injection of azaperone (Stresnil®; 2 mg/kg BW) just before weaning and were artificially inseminated during the ensuing estrus with 3×109 spermatozoa per dose of an inseminate; 1180 sows served as untreated controls...

Infection of boar-hunting dogs with Paragonimus westermani was investigated in Western Japan. Blood and rectal feces were collected from 441 dogs in the three districts (205 in Kinki, 131 in Chugoku, and 105 in Shikoku District). In a screening ELISA for serum antibody against P. westermani antigen, 195 dogs (44.2%) showed positive reaction. In the 195 dogs, 8 dogs were found excreting P. westermani eggs after molecular analysis of fecal eggs and additional 7 were identified serologically for the parasite infection because of their stronger reactivity against P...

Fresh samples of intestinal contents of three wild pigs originating from the Central Bohemia region were examined for the presence of bifidobacterial strains. During the study, we isolated many fructose-6-phosphate phosphoketolase-positive, strictly anaerobic, irregular rod-shaped bacterial isolates. Three of them were preliminarily identified as representing a novel species of the genus Bifidobacterium because their 16S rRNA gene sequence similarity with the closest relatives of thermophilic bifidobacteria (Bifidobacterium boum DSM 20432T, Bifidobacterium thermophilum DSM 20210T, Bifidobacterium thermacidophilumsubsp...

Spermatogenesis, the complex process of sperm cell development including mitotic cell division and meiosis, relies on spermatogonial stem cells (SSCs). While markers for developing germ cells have been well investigated in mice, developmental stage-specific markers of germ cells in domestic animals have not been identified. Sal-like protein 4 (SALL4) is known as a putative marker for undifferentiated spermatogonia in rodents; however, its expression in domestic animals has not been investigated. The objective of this study was to characterize the expression of SALL4 in the developmental stages of boar testes and SSCs...

Peroxidation damage induces sublethal injury to boar sperm during the storage process. Taurine has already been demonstrated to protect cells effectively from oxidant-induced injury. This study was aimed to evaluate the effect of different concentrations of taurine (0.5, 1, 5 and 10 mmol/L) in Modena diluent on boar sperm quality during liquid storage at 17°C. Ejaculates from sexually mature Duroc pigs were collected, pooled and preserved in the Modena containing different concentrations of taurine. Sperm motility, plasma membrane integrity, acrosome integrity, total antioxidative capacity (T-AOC) activity and malondialdehyde content (MDA) were examined every 24 h...

Adding cryopreservation media with reduced glutathione (GSH) has previously been shown to maintain the motility, membrane integrity and fertilizing ability of frozen-thawed boar sperm, although the effects of GSH on good (GFE) and poor freezability (PFE) ejaculates rely upon the intrinsic ejaculate freezability. The resilience to withstand freeze-thawing procedures has previously been related to the existence of a specific distribution of motile sperm subpopulations, which differs between GFE and PFE. Thus, the main aim of this study was to determine whether the addition of GSH to freezing media has any impact on the distribution of motile sperm subpopulations in GFE and PFE...

Seasonal infertility is a limiting factor in boar fertility, and is increasingly important as climate changes. Spermatogenesis in the boar produces 256 spermatozoa per type A1 spermatogonium, but the process is inefficient such that only 10-30% of these potential spermatozoa are actually produced. Heat further impacts spermatogenesis by reducing the number of specific germ cells produced while increasing the fraction of abnormal sperm. Early studies used whole-animal exposure to simulate seasonal exposure to heat under production settings, but this approach is associated with many confounding factors that make assessment of the mechanisms of heat-induced damage to spermatogenesis difficult...

Porcine teschoviruses (PTVs) constitute 1 of the 31 genera within the Picornaviridae family, comprising at least 13 genetic types (PTV-1 to PTV-13), of which only 11 (PTV-1 to PTV-11) have been recognized as serotypes to date. Specific for swine and wild boars, most PTVs are usually non-pathogenic, but some viral variants cause severe disorders in the central nervous system (Teschen disease) or milder signs (Talfan disease), as well as reproductive, digestive and respiratory disorders and skin lesions. Previous studies revealed a high diversity of teschoviruses circulating in Spanish pig populations...

Microbial environment is one of the important factors that affect the quality of preserved semen. Iodine methionine (IM), participating in the production and activation of metabolic enzymes, is a new type of amino acid chelate. To date, there has been no report to evaluate the effects of IM on boar semen preservation at 17°C. This study was designed to investigate the effects of IM on boar sperm quality and reproductive performance during liquid storage at 17°C and its antibacterial effect. Semen samples collected from six Yorkshire boars were diluted with basic liquid containing different concentrations of IM (0, 20, 40, 80, 160 and 320 μM)...

The evaluation of the genetic variations of Toxoplasma gondii among isolates of a wide variety of animal hosts can provide significant information for better understanding the epidemiology and population structure of the parasite in different geographical areas. The aim of this study was to provide information on T. gondii genetic diversity in host species living in central Italy, which could act as a potential source of human infection. Seventy-seven feline faecal samples, and 36 and 20 diaphragm pillar tissue samples from pigs and wild boars were collected in Umbria (central Italy)...

Androstenone, skatole and indole are main compounds responsible for boar taint, an off-odour in meat of some entire male pigs. Several feed ingredients derived from chicory have been reported to reduce fat skatole levels, while results for indole are more contradictory. The skatole-reducing effect is probably based on the prebiotic effects described for fructan compounds. Inulin and oligofructose have a high and low degree of polymerization, respectively. The fermentation rate decreases with an increasing degree of polymerization, which may result in differing effects of the compounds on skatole and/or indole levels...

Tail biting is detrimental to animal welfare and has negative consequences for producer economy. Poor health is one of the risk factors for tail biting. The first aim of this study was therefore to test for links between health status and behavior related to tail biting at the individual level. The second aim of this study was to test whether variation in cytokines was related to variation in social behavior. These small molecules produced upon immune activation are known to influence behavior both in the direction of withdrawal and increased aggression...

Zika virus (ZIKV) is an important arbovirus that is capable of directly infecting neuronal cells. Infection can cause microcephaly in fetuses and Guillain-Barré syndrome in adults. Recent epidemiological studies have shown that ZIKV is sexually transmitted, especially from infected males to uninfected females. This study aimed to investigate the transmission pattern of ZIKV in semen using boar semen. Experiments were performed ex vivo using semen from healthy boar. The samples were infected with ZIKV, and viral RNA was detected and cell morphology was examined at different time points postinfection...

This study aimed to define sperm membrane protein markers of semen freezability of boars with the aid of a proteomic approach. Semen from fourteen adult boars were subjected to slow freezing and rapid thawing. After thawing, sperm vigor and motility were analyzed, and based on these results, animals were separated into two groups: good (GFEs) and poor freezability (PFEs). Sperm membrane proteins were extracted and subjected to two-dimensional electrophoresis. Stained gels were analyzed by computerized resources to indicate differentially expressed protein spots, that were identified by mass spectrometry...
