  • Publication number: 20090005333
    Abstract: One aspect of the current invention is a method of decreasing an involuntary cull rate in farm animals, wherein the involuntary cull results from infection, disease, morbidity, or mortality. Additionally, milk production, animal welfare, and body condition scores are improved by utilizing methodology that administers the isolated nucleic acid expression construct encoding a GHRH or functional biological equivalent to an animal through a parenteral route of administration. Following a single dose of nucleic acid expression vector, animals are healthier and effects are demonstrated long term without additional administration(s) of the expression construct.

  • Publication number: 20080207543
    Abstract: The intramuscular electroporated injection of a protease-resistant growth hormone-releasing hormone (“GHRH”) cDNA into rat dams at 16 days of gestation resulted in the enhanced long-term growth of the FI offspring. The offspring were significantly heavier by one week of age and the difference was sustained to 10 weeks of age. Consistent with their augmented growth, plasma IGF-I concentration of the FI progeny was increased significantly. The pituitary gland of the offspring was significantly heavier, and contained an increased number of somatotropes (cells producing GH) and lactotrophs (prolactin-secreting cells), and is indicative of an alteration in cell lineages. These unique findings demonstrate that enhanced GHRH expression in pregnant dams can result in intergenerational growth promotion, by altering development of the pituitary gland in the offspring.
