Crossbreeding for Egg Production [PDF]
Poultry Science, 1952 Abstract SEVERAL experiments have been conducted for determining the effect of crossbreeding poultry on rate of growth Most of the investigators seem to be in general agreement that crossbreeding tends to improve growth and hatchability. None of the experiments has been conducted, however, to determine the effect of crossbreeding from the standpoint ...
