Two strategies for enhancing gene expression in transgenic animals are described with particular reference to targeting expression to the mammary gland. Gene constructs in which the protein-encoding DNA sequences are contained within a genomic segment (comprising most or all of the natural introns of the corresponding gene) are shown to be expressed more efficiently than their intronless counterparts. Secondly, co-integrating an otherwise poorly expressed transgene in the vicinity of an actively expressed transgene can dramatically improve its efficiency of expression.
