The identification of biomarkers associated with seminal traits could aid in the selection higher quality ejaculates and benefit swine industry. objective this study was to identify boar plasma proteins sperm motility morphology. Twenty from fifteen adult boars a commercial stud were used for work. After routine semen collection analysis, classified into two groups: high-quality (HQS) low-quality (LQS), based on Semen samples processed separation analysis by 2D SDS-PAGE. Total progressive...
This study aimed to evaluate the nutritional profile of commercial plant-based burgers (PBBs) available in Brazil and assess their suitability for fulfilling requirements. Seven PBBs were selected, based on different protein sources used formulations. The proximate mineral compositions evaluated, fatty acid amino profiles determined. contents ranged from 5.25 ± 0.37 13.55 1.16 g/100 g made quinoa a mix proteins, respectively. studied can offer between 46 71% essential (EAA) In addition,...
Mesenchymal stem cells (MSCs) due to their self-renewal potential and differentiation capacity are useful for tissue regeneration. Immunomodulatory trophic properties of MSCs were demonstrated suggesting use as medicinal signaling able positively change local environment in injured tissue. Equine endometrosis is a progressive degenerative disease responsible glandular alterations endometrial fibrosis which causes infertility mares. More precisely, this characterized by phenotypic changes the...
The objective was to determine the effects of corticotherapy, in presence and absence uterine inflammation, on proteomics endometrial fluid from mares susceptible endometritis. In 11 mares, estrus induced seven times with 5 mg PGF(2α) given at 14-day intervals. first a control (no treatment). During third estrus, received glucocorticoid (GC) treatment (20 isoflupredone acetate) every 12 h, for three consecutive days. fifth Infected (intrauterine infusion 1 × 10(9) colony-forming unit/mL...
There is a complex cascade involving proteins during early embryo development and maternal recognition, which very important for maintenance of conceptus. The aim this study was to compare proteomic profile uterine fluid after ovulation in pregnant cyclic mares. In the first cycle, samples 30 mares were collected on days 7 (n = 10), 10 10) 13 post constituted Cyclic group. second same bred fertile stallion. At 7, collected. Immediately sample collection, mare's uteri flushed, those with an...
Corticotherapy is a common treatment in mares susceptible to endometritis. Isoflupredone improves pregnancy rates and affects the protein profile of endometrial fluid comparison untreated mares. Dexamethasone decreases postbreeding accumulation uterine edema; however, its effects on have not yet been studied. The aim present study was verify effect dexamethasone fluid, presence or absence infection, from persistent Nine aged between 7 18 years were used. After checking for signs estrus,...
The aim of the present study was to evaluate effect prepartum artificial photoperiod on pregnancy length and reproductive performance in mares.The included 145 Thoroughbred mares with age between 4 23 years.The were submitted a 15 hour light/9 dark photoperiod/day (10W/m 2 ) during different lengths time before foaling, constituting following groups: <30: less than 30 days photoperiod; 30-45: from 45 46-60: 46 60 >60: more photoperiod.In moment delivery, classified according body condition...
Osteopontin (OPN) is a multifunctional phosphoprotein that has been linked to fertility in bulls. However, the exact mechanism by which OPN contributes fertilisation yet unknown. The biotechnological use of bovine reproduction promising but some gaps remain unfilled. present work aimed: (a) verify whether seminal plasma associated with traits and standard breeding soundness exam; (b) predict interactions integrins, CD44 glycosaminoglycans through molecular docking; (c) develop protocol for...
Plasma concentrations of FSH, LH, oestradiol and progesterone were studied daily during 12 interovulatory intervals 21 periovulatory periods in nine Miniature ponies. The peak the FSH surge that was temporally associated with emergence future ovulatory follicle occurred when ~9 mm, compared a reported diameter 13 mm larger breeds. LH involved slow increase between Days 18 (ovulation = Day 0; 0.6 ± 0.1 ng day–1), minimal or plateau on to (0.04 rapid after (2.2 0.4 day–1; P < 0.0001). end...
Characterization of the uterine proteome before entry conceptus to uterus is essential know factors involved in physiological events gestation. The objective study was compare proteomic profile fluid collected on day 5 post ovulation cyclic and inseminated mares. Samples endometrial secretion were recovered over 2 cycles during fifth ovulation. first cycle constituted Cyclic group following cycle, same mares considered as Inseminated group. All samples subjected two-dimensional...
No presente trabalho, são apresentados dados sobre o diagnóstico de gestação realizado por ultra-sonografia em 45 rebanhos ovinos, durante seis períodos reprodutivos. Foram examinadas 27.089 ovelhas comerciais, acasaladas outono. A porcentagem prenhez(PP) variou 77,3 a 89,9%, com uma PP média 81,6%. Rebanhos raças carne (Hampshire Down, Suffolk e Texel) mostram mais elevada que foi 85,6%, seguidos cruzas, 82,9% finalmente lã (Merino Australiano, Corriedale Ideal) 80,8%. Prováveis causas...
The effect of side corpus luteum on uterine gene expression and protein localization estrogen receptor α (ERα) progesterone (PR) in healthy cyclic pregnant mares 13 days after ovulation (day 0) was investigated. Transcervical biopsies were performed to collect endometrium ipsilateral contralateral regarding the day post-ovulation (n = 6) mares. Blood samples collected daily from 0 until biopsy for 17β-estradiol (E2) (P4) determinations. Receptor determined by immunohistochemistry transcript...
