The objective of the present study was to evaluate estrus synchronization and conception rate after progesterone releasing intravaginal device (PRID) treatment from the early luteal phase in the presence or absence of estradiol benzoate (EB) in heifers. Heifers (n=11) were assigned randomly to two treatments; insertion of a PRID containing 1.55 g progesterone with a capsule attached including 1...

The global proteome of sperm and seminal plasma of fertile stallions was investigated to determine whether associations with relative in vivo fertility exist. Seven stallions at stud in a commercial breeding station were collected throughout the breeding season and bred to a total of 164 mares to determine conception rates. On three occasions during the breeding season, raw semen was obtained f...

The present investigation was carried out to assess the effect of Sephadex (G-15) filtration on the post thaw bull semen quality and conception rate. Post thaw unfiltered (control) and Sephadex filtered semen from four healthy bulls (three cross bred and one pure bred Holstein Friesian) were subjected to microscopic examination viz. sperm concentration, individual motility, live sperm count and...

coccidiosis is a common disease of poultry breeding industry in the world that cause by eimeria spp. objective of the present study was comparison of anticoccidial effect of diclazuril and toltrazuril and their effects on the breeding function and intestinal oocyst shedding rate. therefore, 300 broilers from ross breed with 47 gr weigth average were divided into 3 groups randomely. then chicken...

We studied the immunomodulatory and clinical effects of the empirical formula "tiaomian III decoction" on maternal blood blocking antibody deficiency and recurrent spontaneous abortion. Sixty-one patients with blocking antibody deficiency were divided in the experimental group (N = 31), who took tiaomian III decoction, and the control group (N = 30), who received active immunotherapy with pater...

The recent decline in fertility is a serious problem in the dairy industry. To overcome this problem, we performed a genome-wide association study using 384 Holsteins and identified four loci associated with conception rates. Two of them contained gap junction-related genes: PKP2 and CTTNBP2NL. Further analysis confirmed that PKP2 increased connexin 43, a gap junction protein, whereas CTTNBP2NL...

BACKGROUND The efficacy of preventing perinatal transmission (PT) of human immunodeficiency virus type 1 (HIV-1) depends on both viral load (VL) and treatment duration. The objective of this study was to determine whether initiating highly active antiretroviral therapy (ART) before conception has the potential to eliminate PT. METHODS A total of 8075 HIV-infected mother/infant pairs included ...

OBJECTIVE To investigate whether assisted conception is associated with an increased risk of admission to a residential early parenting program for treatment of maternal mood disorder or infant feeding or sleeping disorders in the postpartum year. DESIGN Systematic audit of consecutive medical records. SETTING Masada Private Hospital Mother Baby Unit (MPHMBU), Melbourne, Australia. PATIEN...

OBJECTIVE To evaluate the effect of hysterosalpingo-contrast sonography (HyCoSy) on natural conception in the infertile patient. METHODS We conducted a prospective observational study recruiting 180 patients admitted to Infertility Center of Ferrara University from January 2010 to February 2012. The essential inclusion criteria was the couple's desire to perform only diagnostic evaluation on ...
