The insulin receptor substrate 1 (IRS1), phosphoinositide 3-kinase (Pi3k), protein kinase B (Akt1), Forkhead Box O3a (FOXO3a) pathway is directly involved in aging and ovarian activation of follicle growth. Therefore, the aim this work was to measure expression genes related for primordial follicles FOXO3a phosphorylation between young old female Ames dwarf (df/df) normal (N) mice.For study ovaries from N (n = 10) df/df mice were collected at 5-6 months age 21-22 age. For...
The method of transportation and the conditions imposed on ovarian tissue are pivotal aspects for success cryopreservation (OTC). aim this study was to evaluate effect size (e.g. whole ovary, biopsy transplant size) during different times storage (0, 6, 12 24 h) structural integrity equine transported at 4°C. Eighteen pairs ovaries from young mares (<10 years old) were harvested in a slaughterhouse processed simulate fragment sizes (biopsy groups) or kept intact (whole ovary group) stored...
Abstract Many microorganisms from various sources may be present in ejaculates of bulls. This study identified and isolated bacteria bull sperm samples a commercial stud evaluated their resistance to antibiotics. The number colony‐forming units was determined semen collected at distinct steps during freezing thawing. minimum inhibitory concentration the bactericidal were for four antibiotics commonly used studs. A total 135 25 genera isolated. After sensitivity test, all ( n = 55) resistant...
To evaluate reproductive and financial performance for commercial swine herds grouped on the basis of pattern removal female swine.Cohort study.25 herds.Lifetime productivity was summarized as number pigs weaned per herd day mated days pig female. Factors associated with these 2 measures were determined by use linear regression. Financial data from a database used to estimate maximum parities at profitability. Sensitivity analysis simulate how variations in daily maintenance cost value would...
Although fixed-time artificial insemination (FTAI) protocols are available for sheep, estrus resynchronization has not been previously reported. The objectives of this study were to evaluate the effect with exogenous progestogen on endogenous progesterone levels and compare pregnancy rates after two consecutive synchronizations in ewes. In Experiment 1, ewes (n = 20) received an intravaginal device (IVD) containing 60 mg medroxyprogesterone acetate (MPA) 10 days. At IVD withdrawal (D0), 250...
This study evaluated the quality of frozen-thawed dog spermatozoon after inclusion egg yolk plasma (EYP) instead whole (EY) in cryopreservation extender and distinct periods exposure to EYP. Seven mongrel dogs were used as sperm donors, EYP was obtained by centrifugation. In Experiment 1, post-thawing motility (MOT) integrity membrane (INT) acrosome (ACR) superior for extended with 20% T2 than EY (P < 0.05), although normal morphology (MOR) did not differ > 0.05). 2, ejaculates cooled at 5°C...
