Boar semen cryopreservation remains a challenge due to the extension of cold shock damage. Thus, many alternatives have emerged improve quality frozen-thawed boar sperm. Although use seminal plasma arising from sperm-rich fraction (SP-SRF) has shown good efficacy; however, majority actual sperm evaluation techniques include single or dual parameter analysis, which overrates real viability. Within this context, work was performed introduce flow cytometry fourfold stain technique for...
Boar spermatozoa arising from the sperm-rich ejaculate fraction are reported to have a more stable plasma membrane and resistant cold shock premature acrosome reaction than whole ejaculate. Furthermore, seminal (SP) can increase cryotolerance of boar spermatozoa, in other domestic species, it has ability reverse cryopreservation damage. This study aimed evaluate effects SP (SP-SRF) on integrity, stability, peroxidation sperm membranes after thawing. Each ( = 24) was divided among 4...
The production of reactive oxygen species (ROS) in boar spermatozoa increases refrigeration; this can have an impact on sperm quality and fertilization capacity. We evaluated the effect polyphenol-rich aqueous extract murtilla ( Ugni molinae Turcz) stored at 17°C order to reduce oxidative stress improve long term. Five experiments were performed: first, characterization polyphenol content from five genotypes murtilla; second, determination genotype with best antioxidant (MT-Ex); third,...
Abstract Holding at room temperature is the first step in most boar semen cryopreservation protocols. It well accepted that a holding time (HT) of 24 h increases sperm cryotolerance. However, effect HT on ejaculates with different freezability not entirely clear. The aim this study was to understand how influences spermatic and seminal plasma metabolite profiles these possible changes affect freezability. A total 27 were collected extended 1:1 (v: v) BTS split into two aliquots. aliquot...
Fatty acids are important in male reproductive function because they associated with membrane fluidity, acrosome reaction, sperm motility and viability, but limited information exists about the fatty acid profile of ram semen. Our aim was to determine composition spermatozoa seminal plasma. Sixty ejaculates were obtained from three (20 ejaculates/ram) using artificial vagina. Ram (RS) plasma (SP) separated centrifugation, analysed by gas chromatography. Total lipids 1.8% 1.6% Saturated (SFA)...
ABSTRACT: To date, no studies have been performed evaluating the effect of boar spermatozoa concentration in 0.5mL freezing straws, leading us to examine this question. Each sperm-rich fraction ejaculate (n=25) was diluted at five different sperm concentrations (100, 200, 300, 600 and 800 x 106 spermatozoa/mL), packaged subsequently frozen. After thawing, from all treatment groups were analyzed determine motility characteristics using a class analyzer (SCA-CASA), their plasma acrosomal...
The risk of chronic diseases such as cardiovascular disease, cancer, inflammation, obesity, and autoimmune disease is linked to the quality dietary fats, with lower intake saturated higher n-6 n-3 polyunsaturated fatty acids (PUFA) considered beneficial health. This study investigated effect supplementing sows’ diets cow’s milk biofortified or PUFA, at varying n-6/n-3 ratios (8.26, 7.92, 2.72) during their growing phase throughout gestation lactation on reproductive performance...
This study evaluated the effects of supplying altrenogest from day 6-12 pregnancy on endometrial glandular epithelium, corpora lutea (CL) morphology, and CL gene expression. A total 12 crossbred females (Landrace × Large White) were used. The assigned to 4 treatments according a random design with 2 factorial arrangement, two categories (sow or gilt) (non-treated treated altrenogest). On 6 pregnancy, animals allocated one following groups: non-treated (NT, n = 6; 3 sows gilts), (T, gilts)...
O botulismo é uma doença causada pela bactéria Clostridium botulinum, que produz neurotoxina levando a sintomas neurológicos graves. Foram documentadas quatro formas de botulismo, sendo alimentar mais comum. A confirmação do diagnóstico feita por testes laboratoriais. estudo buscou identificar as características na população pediátrica em comparação com adultos. utilizou dados SINAN-DATASUS referentes casos no Brasil 2007 2022, extraídos meio script linguagem R. Variáveis como sintomas,...
