Abstract

The frequency of insemination in hens affects the costs associated with artificial insemination in poultry. A reduced frequency implies a larger insemination interval and therefore a reduction in costs. The objective of the study was therefore to assess the effect of insemination intervals on...

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,...

AbstractFull Text

Morphological characteristics of turkey Meleagris gallopavo semen were recorded and hatchability percentages of the artificially inseminated hens were assessed. To study the effect of natural mating on hatchability 15 (3♂, 12♀) M. gallopavo were randomly selected, were kept separately and were...

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

The objective of this study conducted was to determine the influence of different levels of sperm concentration, including catalase (CAT) and vitamin E (VitE) in rooster semen extender on postthawed quality and fertility of rooster semen. Semen was collected twice a week from six roosters (Arian)...

Abstract

DNA uptake in the post-acrosomal region of the spermatozoa takes place exclusively in immotile spermatozoa that are naturally unable to fertilize eggs. The present study aimed to assess whether passive transmission of non-viral vectors to the surrounding areas of chicken embryos could be an...

Abstract

The purpose of this study was to evaluate the optimum number of spermatozoa for highest fertility in Ross-308 broiler breeder chicken. About 24 Ross hens in 4 treatment groups were used. Semen was collected from 8 Ross roosters by abdominal massage and pooled in glass tube. After initially dilution ...

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...

AbstractFull Text

Cryopreservation of domestic animal spermatozoa has been widely used for artificial insemination and egg yolk is one of the most commonly used cryoprotectants during the freezing-thawing process. The aim of the present study was to compare the effectiveness of different duck egg yolk (DEY)...

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 ...
