Abstract: The present invention relates to methods of modulating traits, particularly production traits, in avians such as chickens. In particular, the invention relates to the in ovo delivery of a dsRNA molecule, especially siRNAs, to modify production traits in commercially important birds.

Abstract: The present invention relates to a polypeptide based toxin that originates from Clostridium perfringens. The invention further relates to immunogenic compositions comprising the toxin and methods to vaccinate animals, for example chickens, such that they are less susceptible to clostridial diseases. Methods to determine whether an animal has been exposed to the toxin, polynucleotides encoding the toxin and attenuated bacteria that express a reduced or less active form of the toxin are also disclosed.

Abstract: The present invention relates to nucleic acids and methods for modulating the sex of avians. In particular, the invention relates to the in ovo delivery of a dsRNA molecule, especially siRNAs, to increase the production of female birds.

Abstract: The present invention relates generally to novel recombinant polypeptides having avian cytokine properties and to genetic sequences encoding same. More particularly, the present invention is directed to recombinant avian Type III interferon polypeptides, and genetic sequences encoding same, together with cellular expression systems and uses for same. Even more particularly, the present invention is directed to avian interferon-? (IFN-?) and functional derivatives, homologues and fragments thereof and to methods of use thereof. The molecules and cells of the present invention are useful in a wide range of applications including, but not limited to, providing a means for the treatment and prophylaxis of disease conditions, in particular avian disease conditions, or for use as an immune response modulator. Also provided are diagnostic means for screening for immune response and screening means for identifying modulators of IFN-? protein or nucleic acid functionality.
