The male parent seems to play the im- portant and really decisive role. This has been brought out as a new fact by the most thorough and scientific inves- tigations made by the Maine Experi- ment Station (a station that has done so much for the poultry keeper). In regard to the influence of good roos- ters, Dr. Raymond Pearl, of that station, says in Farm and Fireside: "How does a hen ever get to be high layer if she cannot inherit this quality from her mother ? The answer is simple: The high-laying hen gets the excess- production factor, which is necessary to make it a great producer, from its sire. " Here, too, is evidently the clue to the riddle which has puzzled so many who have trap-nested their flocks, when they find that some high-producing hens have good laying daughters, while other equally high producers have daughters that are poor layers. It all turns on the male used as the sire. De- pending upon the hereditary constitu- tion of the males used, it is to be ex- pected that different proportions vary- ing all the way from 100 percent to none, of the daughters of a high-pro- ducing hen will be themselves high producers. This is proved by experi- ments extending over a period of years, and involving a large number of birds, 'these results demonstrate the importance of getting the proper kind of males with respect to their heredi- tary constitution if one is to make per- manent and definite progress in breed- ing for increased egg production. "The aim is to get males that are 'pure-bred' in regard to the excess production factor. These can only come from high producing mothers bred with certain types of males. It is of the utmost importance in any scheme of breeding for production to select high-laying females, but it is not, as has been generally s
