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

Artificial insemination is commonly used in breeder farms to stabilize fertility. Hens are able to store sperm for a long time and remain fertile, so that they can extend the chicken insemination interval, and thus achieve better economic benefits. In this paper, dwarf brown-shell laying hens were...

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

Artificial insemination (AI) in vitro had been pioneered by Russian scientist V.P. Vrassky (1855) and later has been developed and advanced by I.I. Ivanov. The latter has been the first who inseminated hens artificially with the sperm obtained from the seminal ducts of slaughtered cocks (1902). AI...

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

Artificial insemination made a predominant contribution towards the improvement of genetic potential and increased productivity in animal husbandry sectors. In frozen semen technology, about 50% of sperm died because of cryoinjury or cryodamage during the process of cryopreservation and thawing of...

Abstract

Since early fertility decline is a permanent problem of broiler breeders, the aim of this study was to test the effects of various sex ratios, spiking strategies and additional artificial inseminations (AI) on their breeding efficiency. Six breeder flocks were analysed during the whole reproduction ...

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

Female birds store sperm in sperm storage tubules (SSTs) in the uterovaginal junction of their reproductive tract for days or weeks (depending on species) before fertilization. Sperm are transported from the SSTs to the infundibulum where fertilization occurs immediately after ovulation of each...
