"FDA's "Animal Health" section for the post-puberty period in pig clones consists of a single sentence: "No reports on aging and maturity in swine clones were identified." The Agency later repeats that it "was not able to identify any peer-reviewed studies on non-reproductive postpubertal studies (sic) in swine clones." Thus, the Agency relies solely on the Viagen data for this period, which, as noted above, consisted of data on just five clones, and found that clones weighed less than natural comparator animals and had reduced marbling and back-fat thickness."
