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 …

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

At the time of the first Transgenic Animal Research Conference, the lack of knowledge about
promoter, enhancer and coding regions of genes of interest greatly hampered our efforts to …

The improvement of animal production by transgenesis is expected to be complementary to
other breeding techniques including genetic selection (by conventional methods and using …

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 livestock came into existence in 1985 with the production of the first transgenic
pigs and sheep (Hammer et al., 1985). Since then, various technologies have been …

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 …

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 …

The introduction of foreign DNA into the genome of livestock and its stable integration into
the germ line has been a major technical advance in agriculture. Production of transgenic …

The first transgenic livestock were produced in 1985 by microinjection of foreign DNA into
zygotic pronuclei. This was the method of choice for more than 20 years, but more efficient …
