Abstract

Guinea fowl hens were inseminated weekly once with two doses of spermatozoa (75 million and 100 million) in two different diluents, Beltsville poultry semen extender (BPSE), and Instruments for Veterinary Medicine (IMV), each with and without pre-insemination vaginal douching. Per cent fertility,...

Abstract

In birds, after natural mating or artificial insemination (AI), sperms are transported through cloaca or vagina at the utero-vaginal junction (UVJ) of oviduct. Only 1% of the deposited sperm passes through the selection process in the vagina to reach the UVJ. In the UVJ, sperm enter the tubular...

Abstract

Lactobacillus resides in the hen's gastrointestinal tract, vagina and cloaca. When fed to hens, Lactobacillus has improved egg weight, size and shell strength. However, data from our lab suggests Lactobacillus may be detrimental to semen and possibly fertility. Therefore, the objective of this...

Abstract

Located at the anterior end of the turkey hen's vagina are numerous discrete tubular invaginations of the surface epithelium, collectively referred to as the sperm storage tubules (SSTs). After mating or artificial insemination, sperm ascend the vagina, enter the SSTs, and over the ensuing days and ...

Abstract

Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. However, the precise mechanisms by which sperm are kept alive in the SSTs are still not fully understood. The aim of this study was to determine whether exosomes are secreted by SST cells and play...

Abstract

In this study, whether the secretion of the uterine fluid (UF) exerts a role in the prolongation of functional life-span of the sperm in the hen oviduct was evaluated. The sperm were subjected to upper vaginal artificial insemination (AI) in the vicinity of the utero-vaginal junction (UVJ) under...

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

Egg yolk is one of the most widely used cryoprotective components for sperm preservation and a wide range of factors affect its action on sperm motility, viability and fertilizing ability. The aim of this experiment was to determine the effect of different species egg yolk, namely the domestic...

Abstract

90 White Leghorn (W.L.) ♀♀ were inseminated with semen from 2 W.L. and 2 Red White-tailed ♂♂ Egg fertility in the periods 2-6 and 2-11 days after insemination was 86.8 and 64.0% resp. from vaginal inseminations, and 68.4 and 52.9% from intra-peritoneal inseminations; corresponding figures for...

Abstract

With the " Hiroshima" technique the ♀ is restrained in a special bird holder which suspends the bird so that its abdomen is fully exposed and can easily be massaged. Semen is collected in a special funnel-shaped receptacle which is attached over the vent. There are photographs of the apparatus, and ...
