A Study on Genes of Bayanbulak Sheep [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2013
The average twin lambing rate of Bayanbulak sheep is 2% to 3%. However, a flock of sheep with a close genetic relationship and an average of 2 to 3 lambs per birth has been found recently.

The chicken embryo and its micro environment during egg storage and early incubation [PDF]

open access: yes, 2008
When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.

ASSESSMENT OF THE EFFICACY O SEPHADEX FILTRATION OF BUFFALO SPERMATOZOA FOR CRYOPRESERVATION [PDF]

open access: yesVeterinary Medical Journal - Giza, 2006
In the present study, two experiments were conducted. The first experiment aimed to study the influence of buffalo bull semen filtration throughout different grades of sephadex columns (G-25, G-50, G-75, G-100 and G-200) on semen quality.

Global DNA methylation profiles of buffalo (Bubalus bubalis) preimplantation embryos produced by handmade cloning and in vitro fertilization

open access: yesScientific Reports, 2022
Somatic cell nuclear transfer technique (SCNT) has proved to be an outstanding method of multiplication of elite animals but accompanied with low efficiency and live birth rate of cloned animals. Epigenetic alterations of DNA has been one of the culprits

CRISPR/Cas9-mediated mutation of tyrosinase (Tyr) 3′ UTR induce graying in rabbit

open access: yesScientific Reports, 2017
The 3′ untranslated regions (UTRs), located at the end of mRNA molecules, are believed to play a role in RNA replication and/or protein translation. Mutations in the tyrosinase (Tyr) gene are known to cause recessive albinism in humans and other species.

Embryo donation families : a follow-up in middle childhood [PDF]

open access: yes, 2007
Couples who conceive using donated embryos rear a child to whom they are genetically unrelated. It has been suggested that this may have negative consequences for parenting and child development.
