| abstract |
The present invention relates, in general, to a method of improving the production performance of poultry, by administering to a bird a heterologous protein comprised of inhibin protein, or a fragment thereof and a carrier protein. The present invention also relates to a method of improving the production performance of poultry by administering to a bird a fusion gene product comprising a gene encoded for expression of avia-subunit inhibin protein -alpha, or a fragment thereof, and a gene encoded for the expression of a carrier protein. An effective amount of the heterologous protein or fusion gene product is administered to an animal such that the immune response against the heterologous protein occurs in the animal. The present invention further relates to the above heterologous protein and fusion gene product and the production methods thereof. |
