Abstract

One of the primary goals of traditional livestock breeding is to improve growth rate and optimise body size. Growth rate can be significantly increased by integrating a growth hormone (GH) transgene under the control of a ubiquitous promoter, but while such animals do demonstrate increased growth there are also serious deleterious side-effects to the animals health. Here we report the generation and initial characterization of transgenic mice that carried a porcine BAC encoding the porcine GH gene. We show that GH expression is restricted specifically to the pituitary, is associated with elevated IGF-1 levels, and results in growth enhancement. No negative effects to the health of the transgenic animals were detected. This initial characterisation supports the use of BAC pGH transgene in livestock studies.
