Transgenesis in farm animals
The production of transgenic animals has many biotechnological applications; however, available techniques still remain inefficient. This review summarizes the contributions of our group to transgenesis in domestic animal. One of the most traditional transgenesis techniques in farm animals is somatic cell nuclear transfer using genetically modified somatic cells. Using this technique, we produc...
متن کاملEfficient transgenesis in farm animals by lentiviral vectors.
Microinjection of DNA is now the most widespread method for generating transgenic animals, but transgenesis rates achieved this way in higher mammals are extremely low. To address this longstanding problem, we used lentiviral vectors carrying a ubiquitously active promoter (phosphoglycerate kinase, LV-PGK) to deliver transgenes to porcine embryos. Of the 46 piglets born, 32 (70%) carried the tr...
متن کاملGenetic diversity in farm animals--a review.
Domestication of livestock species and a long history of migrations, selection and adaptation have created an enormous variety of breeds. Conservation of these genetic resources relies on demographic characterization, recording of production environments and effective data management. In addition, molecular genetic studies allow a comparison of genetic diversity within and across breeds and a r...
متن کاملMolecular Markers for Fertility in Farm Animals
A genetic marker is a gene or DNA sequence with known localization on a chromosome. It can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. Such variations occurring at chromosomal or DNA level can serve as genetic markers. The progress in development of molecular markers suggests thei...
متن کاملA review of leptospirosis in farm animals in Portugal.
This paper presents a review of Leptospira infection in farm animals in Portugal which is based mainly on serological results obtained in the National Veterinary Research Laboratory between January 1987 and December 1993. Serum samples were tested by the microscopic agglutination test, at a minimum dilution of 1:100. Positive titres were obtained in 15.3% of the 9,543 bovine samples examined. S...
