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...

Abstract

A total of 160 Inshas and Gimmizah laying hens, 35 weeks of age, was divided into eight groups of 20 hens each. Groups 1 and 3 were inseminated once a week, while groups 2 and 4 were inseminated twice a week. The depth of intravaginal insemination was 3 cm in groups 1 and 2 and 5 cm in groups 3 and ...

Abstract

Our objectives were to evaluate: (1) the efficacy of the Sperm Mobility Test on commercial turkey farms, and (2) the influence of sperm mobility phenotype on fertility when insemination parameters are varied. In research flocks, differences in sperm mobility among toms are predictive of fertility....

Abstract

White Leghorn hens were artificially inseminated at 13.00 and 16.00 h with differently treated frozen semen stored over different periods. Lake's diluent with 11 per cent glycerol was effective for cryopreservation of fowl semen. The Beltsville poultry semen extender (BPSE) with 4% dimethyl...

Abstract

Semen was collected 3 times a week from 48 roosters and pooled. Semen was cooled and 4, 6, 8 or 11% glycerol, dimethyl sulfoxide (DMSO) or dimethylacetamide (DMA) were added. Samples were then frozen in straws or as pellets and were thawed in water bath at 5°C or on a hot plate at 60°. The...
