In Japan, the development and application of living modified organisms (LMOs) are regulated by law (conservation and sustainable use of biological diversity law). Procedures are classed as type 1 for the use of LMOs where no preventive measures against their dispersal into the environment are required and type 2 for the use of LMOs where preventive measures are stipulated. Development and research on transgenic livestock falls under the responsibility of the Ministry of Education, Culture, Science, Sports and Technology. Field use of transgenic livestock is controlled by the Ministry of Agriculture, Forestry and Fisheries. The author describes risk assessment and management of transgenic livestock by both ministries.

Porcine epidemic diarrhoea virus (PEDV) is a porcine enteric coronavirus, outbreaks and epidemics of which have caused huge economic losses to the livestock industry. The disadvantage of existing PEDV vaccines is that the unstable efficacy and high cost limit their widespread use. Therefore, there is an urgent need to develop a recombinant transgenic vaccine candidate for PEDV.

Background And Aim: Papillomaviruses (PVs) infections have been documented in numerous animal species across different regions worldwide. They often exert significant impacts on animal health and livestock production. Scientists have studied natural products for over half a century due to their diverse chemical composition, acknowledging their value in fighting cancer.

Polyunsaturated fatty acids (PUFAs) such as linoleic acid (18:2, n-6) and α-linolenic acid (18:3, n-3) are essential for the growth, development, and well-being of mammals. However, most mammals, including humans, cannot synthesize n-3 and n-6 PUFAs and these must be obtained through diet. The beneficial effect of converting n-6 polyunsaturated fatty acids (n-6 PUFAs) into n-3 polyunsaturated fatty acids (n-3 PUFAs) has led to extensive research on the flax fatty acid desaturase 3 () gene, which encodes fatty acid desaturase.

Classical preimplantation embryo culture is performed in static fluid environments. Whether a dynamic fluid environment, like the fallopian tube, is beneficial for embryo development remains to be determined across mammalian species. Objectives of these proof-of-concept studies were to determine if controllable dynamic microfluidic culture would enhance preimplantation murine, bovine, and human embryo development compared to static culture.
