Abstract

The techniques of artificial insemination (Al) have been developed on the basis of the studies on the species-related features of reproduction. The efficiency of Al in poultry depends on dose of sperm; sperm quality; motility and inseminating activity of spermatozoa; preservation of the spermatozoa ...

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...

Abstract

Sperm motility is used to predict the semen quality and fertilization ability of breeder roosters. Indigenous chicken breeder roosters show variation in sperm motility, but less has been known about its relationship with other reproductive attributes. In this study, 40- to 44-wk-old Beijing-You...

Abstract

The in vitro and in vivo functionality of cryopreserved spermatozoa was examined over two breeding seasons in a zoological colony of Magellanic penguins (Spheniscus magellanicus). Frozen-thawed semen was inseminated into five anesthetized females, over a total of eight egg production cycles, with a ...

Abstract

The aim of this study was to evaluate the effects of supplementary CoQ10 in the diets of aged broiler breeder hens on productive and reproductive variables. A total of 128 hens (44 weeks of age) were randomly assigned to one of 16 groups (eight hens per group). The hen-groups (with equal mean egg...

Abstract

This study was designed to evaluate orally administrated Letrozole (Lz) on reproductive performance, plasma testosterone and estradiol concentrations and relative abundance of mRNA of GnRH, FSH and LH in roosters. Ross 308 roosters (n=32) that were 40-weeks of age were individually housed and...

Abstract

Currently most breeds and lines of geese in use at a commercial scale are derived from two wild species; the swan goose (Anser cygnoides L.) and the true goose-greylag (Anser anser L.). Interestingly, local selections performed for centuries from these two ancestors have resulted in strains or...

Abstract

Incidence and effects of epididymal stones on gonad indices in 3 groups of 15 broilers each of breeder grandparent, broiler breeder and indigenous roosters are described. Epididymal stones (ES) were found in the epididymis of all groups. The gonado somatic index, relative epididymal to testes...

Abstract

Having antioxidant and androgenic effects, Chrysin was orally administrated to roosters and reproductive performance including sperm quality and fatty acid composition, testis index, fertility and hatchability rates as well as blood testosterone concentration were assessed. Twenty eight 40-week-old ...
