§ Sir P. Hurd
asked the Minister of Agriculture what stage has been reached at the animal research station at Cambridge under Dr. John Hammond in the treatment of cows of good beef type so as to induce the birth of twin calves, thereby promoting the more economical production of high quality beef in this country.
§ Mr. T. Williams
The work at this station on the inducement of twinning in cattle by the injection, before mating, of pregnant mare serum hormone has not reached the stage at which its practical application can be recommended. Attempts are being made to test the use of the method under commercial conditions with a few cows on farms in the eastern counties.
