The Egg Breeding Work at the Maine Station.

As is well known the Maine Station was for years considered by all poultrymen to be doing a great and beneficial work in breeding for increased egg production. Up until the fall of 1907, the poultrymen of the country were of the opinion that this work was in every way successful, and a large number of private breeders had taken up the use of trap-nests in an effort to build up the egg production of their fowls.

When early in 1908 Bulletin 157 of the Maine Experiment Station was published, it showed by averages as given in the table on page 202 that the egg yield at the station was for the entire period on the decline. In Bulletin 157, the statement was made that "arithmetical mistakes" and "faulty statistical methods" accounted for the discrepancies between the former publications and the criticised data. The further explanation that "the experiment was a success as an experiment," etc., only appeared to the public mind as a graceful way of explaining what was, to the practical man, an utter failure of the entire work.

The unfortunate death of Professor Gowell, together with the fact that he had equipped a private poultry farm with station stock, added to the confusion, and the result of the bulletin was the precipitation of a general "pow-wow" in which the poultry editors were about equally divided between those who were casting insinuations upon the personnel of the station, and those who decried the whole effort toward improving the egg yield.

After going over the publications of Professor Gowell, visiting the station and meeting the present force, I came to the following conclusions regarding the matter:

Professor Gowell's work is open to severe criticism. Errors have been made in conducting the work at Maine which have made it possible for a mathematical biologist to take the data and seemingly prove that selection, as practiced by Professor Gowell, actually resulted in lowering inherent egg capacity of the strain of Plymouth Rock hens under experimentation. Had Professor Gowell's successor been a practical poultryman, it is my candid opinion that the public would have been given a radically different explanation of the results.

Professor Gowell is the author of the following statement: "The small chicken grower is earnestly urged to use an incubator for hatching." This opinion is not in accord with that of the majority of breeders and the more progressive experiment station workers. The opinion has been expressed by Professor Graham and others, that the particular results at the Maine Station may have been due to the decrease of vitality caused by continued artificial hatching. This view may be wholly without foundation. Nevertheless, as the common type of incubator is under heavy criticism, and it is pretty well proven that chicks so hatched have not the vitality of naturally hatched chicks, surely a series of breeding experiments would carry more weight if the replenishing of the flock had been accomplished by natural means.

For the first few years of the breeding work the house used was the old-fashioned double walled and warmed pattern. The last few years of this work were conducted in curtain front houses. That the cool house is an improvement over the warm house is generally conceded, but there are many poultrymen who are still of the opinion that the warm house will give a larger egg yield, though at a greater expense and less profit.

In the early years of the work the method of feeding was also a time-honored one, and included a warm mash. About the middle of the experimental period Professor Gowell brought out the system of feeding dry mash from hoppers. This custom became a great fad and Professor Gowell and Director Woods have preached it far and wide. Perhaps it is an improvement, but it is to-day much more popular with novices than with established egg farms. Many old line poultrymen have tried dry mash only to go back to wet mash, by which method the hens can be induced to eat more which is conducive to high egg yields. Whether these changes in housing and feeding have been improvements as claimed by those who introduced them, or whether their popularity may be explained in part at least by the psychology of fads, is a point in question, but certainly the marring of a breeding experiment by introducing radical changes in the factors of production is at best unfortunate.

A much more serious criticism than any of the foregoing is to be found in a change of the size of flocks and amount of floor space per fowl. I have gone over carefully the published records of Professor Gowell, and the review of Dr. Pearl, and the following table represents, as near as I can determine, these factors for the series of years. In the year 1903 I find no clear statement as to the manner in which the birds were housed, and I may be in error in this case. Otherwise the table gives the facts.
