Abstract

Four controlled experiments designed to examine aspects of reproductive response in Broad-Breasted males were conducted. 24 males and 168 females were used to evaluate the use of low sperm concentration (30.6 X 106 spermatozoa/AI dose) and examine the relationship of semen characters to fertilising ...

Abstract

The genetic breeding improvement plan carried out in the past decade, put emphasis on the selection characteristics such as weight gain, rapid growth in broiler breeders as cause of reduced fertility rate. This occurred due to the negative correlation between reproductive and productive trials....

Abstract

In order to introduce artificial insemination (AI) for genetic and offspring improvement in turkey population, viable sperm concentration (VSC) was used to choose the breeding males. In addition, technological definitions were established as the timetable frequency, as well as the sperm dose and...

Abstract

A new flow cytometric method has been developed to rapidly determine sperm concentration and viability in semen from bulls and boars. Sperm viability was determined on the basis of staining with SYBR-14 and propidium iodide (PI), and this allowed detection of live (membrane-intact) sperm, dying...

Abstract

Our goal was to determine whether there is any correlation between the mRNA expressions of transforming growth factor β (TGFβ)-isoforms/their receptors and the fertility in chicken sperm stored in vitro for different times. The semen collected from White Leghorn roosters was divided into diluted...
