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

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

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

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

Transplantation of male germ line cells into sterilized recipients has been used in mammals for conventional breeding as well as for transgenesis. We have previously adapted this approach for the domestic chicken and we present now an improvement of the germ cell transplantation technique by using...

Abstract

In the present study, anti-viral transgenic chickens were developed by transfecting spermatogonial stem cells (TTSSCs) with the fusion gene ECFP-MMx. After injection of the fusion gene ECFP-MMx into testis, frozen testis sections underwent PCR and dot blot testing at 30, 40, 50, 60, 70 and 80 days. ...

Abstract

This study was carried out to determine the optimum frequency of semen collections, dilution rate, and artificial insemination dose of Domyati duck semen in order to set up the commercial semen quality which could be applied to the conservation of genetic resources, breeding, and commercial...

Abstract

Five so-called Osaka ducks of the Pékin breed were artificially inseminated with semen from a Muscovy drake. The semen was obtained by electro-ejaculation and diluted 1: 10 with 0. 85% physiological saline solution. The insemination technique used has already been described [see A. B. A., 26, No....

Abstract

THE semen is injected by a hypodermic syringe penetrating the skin in the ovarian region to a depth of 6-8 cm. depending on the size and conformation of the bird. An adequate dose is 0.05-0.l cm.3, which may be discharged in one place or spread over the area by moving the needle slightly. The risk...
