Considerable progress has been made in methods for production of transgenic livestock;
beginning with pronuclear microinjection over 20 years ago. New methods, including the …

The introduction of specific genes into the genome of farm animals and its stable
incorporation into the germ line has been a major technological advance in agriculture …

Current applications of gene transfer in farm animals include the improvement of product
quality and quantity, disease resistance, the production of valuable proteins in the mammary …

Transgenic research usually involves a large investment in carrying out a series of low-
efficiency steps to produce a few transgenic founder animals, and then characterizing a …

Microinjection of DNA that contains genes into the pronuclei of zygotes from pigs, sheep,
cows and goats has resulted in the production of “transgenic” livestock containing new …

Transgenic animals are produced by introducing 'foreign'DNA into the genetic material of
pre-implantation embryos. This DNA is present in all tissues of the resulting individual. This …

Transgenic animal technology is one of the most fascinating technologies developed in the
last two decades. It allows us to address questions in life sciences that no other methods …

The notion of directly introducing new genes or otherwise directly manipulating the genotype
of an animal is conceptually straightforward and appealing because of the speed and …

Microinjection of DNA constructs into pronuclei of zygotes has been the method of choice for
the generation of transgenic livestock. However, this procedure is characterized by low …

Until recently, pronuclear microinjection of deoxyribonucleic acid (DNA) was the standard
method for producing transgenic animals. This technique is now being replaced by more …
