After thirteen years of effort, a state-owned agency has scrapped its program, citing unacceptable death rates:
Only about 10 per cent of cloned animals survived through the trials, with the main problems being spontaneous abortions and hydrops – where a cow’s uterus filled up with water, leading to the mother being euthanised as well.
The work was being done ultimately for the benefit of humans, but Dr Suttie said scientists took animal welfare standards and ethical issues very seriously.
So seriously that they continued this boondoggle of a program, which caused staggering amounts of animal suffering, for thirteen years. (Thanks, Jeannie.) Link.
