GLAND EXPERIMENTS
BREEDING OUT OF SEASON. SHEEP AND COWS REACT. Two British scientists, Dr I. Hammond, a Cambridge animal geneticist, and Dr A. S. Parkes, of the Medical Research Council, are making sheep breed out of season, which in Britain is from August to February. The method is to inject into the ewe hormone obtained from the pituitary gland of the horse. Ewes so treated at Cambridge farm school last June, _ two months before the start of the normal breeding season, have lambed successfully. All the animals arc quite healthy. Large-scale experiments are being carried out on Essex. Suffolk, Norfolk. Glamorgan. Lincolnshire and Scottish farms. It is even possible that in future the lamb crop may be trebled or quadlupled. Ewe lambs, too, can be made to breed in the first year of life instead of at 18 months old, as at present.
Cows have also been injected at the Cambridge Farm Sclfool, in the hope that twins may be induced in beef breeds.
