Livestock meat is generally low in n-3 polyunsaturated fatty acids (PUFAs), which are beneficial to human health. An alternative approach to increasing the levels of n-3 PUFAs in meat is to generate transgenic livestock animals. In this study, we describe the generation of cloned pigs that express the cbr-fat-1 gene from Caenorhabditis briggsae, encoding an n-3 fatty acid desaturase. Analysis of fatty acids demonstrated that the cbr-fat-1 transgenic pigs produced high levels of n-3 fatty acids from n-6 analogs; consequently, a significantly reduced ratio of n-6/n-3 fatty acids was observed. We demonstrated that the n-3 desaturase gene from C. briggsae was functionally expressed, and had a significant effect on the fatty acid composition of the transgenic pigs, which may allow the production of pork enriched in n-3 PUFAs. © 2013 Springer Science+Business Media Dordrecht.
