Abstract

Transplantation of male germ line cells into sterilized recipients has been used in mammals for conventional breeding as well as for transgenesis. We have previously adapted this approach for the domestic chicken and we present now an improvement of the germ cell transplantation technique by using...

Abstract

This study was carried out to determine the optimum frequency of semen collections, dilution rate, and artificial insemination dose of Domyati duck semen in order to set up the commercial semen quality which could be applied to the conservation of genetic resources, breeding, and commercial...

Abstract

In the present study, anti-viral transgenic chickens were developed by transfecting spermatogonial stem cells (TTSSCs) with the fusion gene ECFP-MMx. After injection of the fusion gene ECFP-MMx into testis, frozen testis sections underwent PCR and dot blot testing at 30, 40, 50, 60, 70 and 80 days. ...

Abstract

The use of artificial insemination (AI) in poultry can be traced back until the beginning of the 20th century. The development of suitable methods to collect sperm as well as insemination, dilution and preservation of sperm have resulted to a useful and significant method in poultry breeding. This...

Abstract

The present study was conducted in order to determine the proper extender for poultry semen among Beltsville, Ringer and milk and the comparison of various proportions of different extenders applied for dilution (semen-over-extender ratios 1:1 and 1:2) and its impact on fertility and semen storage...

Abstract

The semen quality of Cabot's Tragopan, the dependence of sperm yields on frequency of semen collection, and the duration of sperm storage in females were investigated. The results are as follows: (1) The average duration of the period in which Cabot's Tragopan can produce an ejaculate was about 70...

Abstract

Glycerol (GLY) and egg yolk (EY) are good cryoprotectants of avian and mammalian sperm, but in birds, they strongly inhibit the eventual fertilization of ova. Using the sperm penetration (SP-holes) assay and fertility trials, the present study investigates (1) the possible mechanism by which this...

Abstract

Semen cryopreservation is fundamental both for the practice of artificial insemination, and for the conservation of genetic resources in cryobanks; nevertheless, there is still not an efficient standard freezing procedure assuring a steady and suitable level of fertility in fowl, and consequently...

Abstract

The sperm storage tubules (SST) of the turkey hen, which are located in the uterovaginal junction (UVJ) of the oviduct, maintain viable sperm for up to 10 wk after a single insemination. The mechanisms of this in vivo sperm storage are poorly understood. Our objective was to evaluate mRNA and...

Abstract

A series of experiments was designed to evaluate the quality of cryopreserved rooster sperm and its fertility so that programs needing to bank germplasm and recreate animals can do so utilizing a minimal amount of cryopreserved semen. In experiment 1, rooster semen from the National Animal...
