Bird flu study highlights need to vaccinate flocks effectively

...nfectious Diseases, said: "Vaccination reduces the chance of birds becoming infected and reduces the amount of virus they shed and the time over which they shed it.

...y." "Because two implanted embryos have twice the chance of MZ twins than a single implanting embryo the best way of minimising MZ as well as DZ twinning is to transfer one embryo at a time, irrespective of the age of the mother to be", he said.
