Gender selected or sexed semen has been commercially available to the dairy industry for almost a decade. However, sexed semen from beef bulls became commercially available only recently. The availability of sexed semen from beef bulls along with concerns about success of the technology at the ranch level has limited the use of sexed semen in purebred and commercial beef operations. Recent chan...

The effect of gelatin addition to the semen extender on the viability and acrosome integrity of rabbit spermatozoa was studied. Pooled semen samples were processed in a boar semen extender with or without gelatin addition. Semen samples were stored at 5 degrees C for 72 h. Viability and acrosome integrity was evaluated by light microscope. Results showed that gelatin addition had a significant ...

The screening and confirmatory tests available to a forensic laboratory allow evidence to be examined for the presence of bodily fluids. With the majority of evidence being submitted involving sexual assaults, it is important to have confirmatory tests for the identification of semen that are straightforward, quick, and reliable. The purpose of this study was to compare two commonly used semen ...

A total of 120 ejaculates from six adult Black Bengal bucks were studied to determine the semen attributes and evaluate their fertility. The various semen attributes of fresh semen were volume, sperm concentration, mass motility, live spermatozoa and normal spermatozoa percentage. All the semen attributes differed significantly (P<0.05) except normal spermatozoa percentage between the bucks. A ...

BACKGROUND Acute lung injury (ALI) is an inflammatory disorder. Semen Cassiae has potent anti-inflammatory activities. The aim of our study was to investigate whether Semen Cassiae plays a protective effect on lipopolysaccharide (LPS)-induced ALI and, if so, to elucidate its potential mechanism. METHODS Male Sprague-Dawley rat lungs were injured by intratracheal instillation of LPS. Rats were...

OBJECTIVE To determine the prevalence of herpes viruses in the semen of an asymptomatic male cohort with and without infertility problems and its association with altered semen parameters. DESIGN A prospective randomized study. SETTING Medical school and IVF clinic. PATIENT(S) One hundred seventy-two male patients undergoing routine semen analysis: 80 with normal semen parameters (control...

The sperm quality index (SQI) is a tool used to predict overall rooster semen quality, fertility, and hatchability. However, semen must be diluted before SQI analysis, and research has shown that the SQI is most predictive of fertility at lower semen dilutions. Therefore, the present study was undertaken to determine why the SQI is not as predictive of fertility at higher semen dilutions and wh...

In this paper, the overall framework for chilled water system in heating, ventilation, and air-conditioning (HVAC) system was analyzed, then aiming at the chilled water system, the control loop in secondary pump frequency pressure difference was identified and the Generalized Prediction Control (GPC) algorithm was designed and deployed for the strategy of fixed pressure difference control. The ...

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...

Semen from 5210 sperm bank donors was analyzed and trends in semen quality were evaluated at Shandong Human Sperm Bank between 2008 and 2014. After 2-7 days of abstinence, semen samples were collected. Measurements of semen volume, sperm concentration, sperm forward motility, and total sperm count were performed. There were significant declining trends in semen volume, sperm concentration, sper...
