Abstract: The present invention provides livestock animals and methods to create recipient animals for spermatogonial stem cell transplantation through modulation of the NANOS gene. In one embodiment genome editing issued to create animals with insertions or deletions (indels) that inactivate or otherwise modulate NANOS gene activity so that resulting males lack functional germ cells yet retain functional somatic cells, and females are fertile. These males can then be transplanted with donor spermatogonial stem cells and used for breeding.

Abstract: The present invention relates to genetically edited swine which produce CD163 protein in which the scavenger receptor cysteine-rich 5 (SRCR5) domain (also known as CD163 domain 5) has been deleted. Such swine have been found to be healthy and do not exhibit negative properties, and are resistant to PRRSV infection. CD163 expressed in the edited swine also demonstrates retention of the ability to function as a haemoglobin-haptoglobin scavenger. Methods of producing such swine are also provided.

Abstract: The present invention relates to a genetically edited animal, especially to a genetically edited pig in which expression or activity of the RELA protein has been modified. Such pigs have at least partial protection against the African Swine Fever Virus. The invention also provides, a cell nucleus, germ cell, stem cell, gamete, blastocyst, embryo, foetus and/or donor cell of a non-human animal comprising a genetic modification which alters the expression or function of RELA protein, methods for editing the genome of animals and methods for screening the efficacy of a pharmaceutical agent in such an animal.

Abstract: The present invention relates to genetically-edited swine comprising an introgressed heterologous nucleic acid sequence in the RELA gene. In particular it relates to genetically-edited swine comprising an introgressed warthog allele in the RALA gene of domestic pigs. The invention also related to methods of producing such swine, and cells derived from swine having such introgressed sequences.
