The present invention relates to the production of recombinant equine chorionic gonadotrophin (reCG), to a veterinary composition comprising reCG, and to the use of reCG or the composition comprising reCG. The reCG of the present invention has a glycosylation profile similar to that of commercially available chorionic gonadotrophins and exhibits the level of in vivo activity corresponding to eCG and similar to that of the FSH and LH hormones. The present invention has application in the field of biotechnology, more specifically, in the field of assisted-veterinary reproduction, being especially suitable for use in the treatment of veterinary conditions related to mammalian reproduction and ovulation, for the manufacture of diagnostic kits or as supplement for cell culture.
