One of the fundamental parts of an education in Poultry Husbandry is the study of the various types and breeds of poultry. In the greater part of the schools and colleges now offering courses in poultry husbandry the judging of typical specimens of the best known varieties and breeds has become one of the important branches of such courses, because it is absolutely essential that every poultryman should have a clear working knowledge of the points that go to make up good birds. One of the best methods of stimulating the attainment of this feature of a poultry course is the bringing into the course of a certain amount of competitive judging, not only between members of a class, but between teams from the various institutions that are conducting similar courses. It was with this idea in mind that the American Association of Instructors and Investigators in Poultry Husbandry through . . .

In starting and organizing the Poultry Extension work in Pennsylvania, it was necessary to first gain the confidence of the County Agents. Of the fifty-seven County Agents in the State none had received more than two courses of instruction in poultry and many had never studied poultry at all. Hence they had practically no interest in poultry keeping and also were unable to be of real service to the poultrymen of their county. Thus in order to prove to the County Agents that poultry keeping was a science and a business it was necessary to show them results. The easiest, quickest and most effective way to get the County Agents as well as the farmers interested in poultry work was by demonstrating the value of culling hens.

To one of the County Agents belongs the idea of conducting contest pens. His statement was this: “I don’t believe in culling hens….

The Association now has more than the usual number of invitations from institutions some of which, if indeed not all, seemed particularly anxious to entertain during this next annual meeting. In view of invitations from such widely separated sections of the country as North Carolina, Ohio, Indiana, Montana, and Oregon, and in view of other considerations presently to be mentioned, the matter of a right decision by the officers and directors of the Association seems to be less easy than usual. In consequence the committee that ordinarily decides the time and place of meeting is appealing to the membership of the Association in the hope that the ultimate choice will be best for all concerned.

The Association has before been Invited to hold its meeting in the West, and indeed on one occasion the committee was within one vote of fixing the place of meeting at the University of Saskatchewan….

The Committee met at the Prince George Hotel in New York City on Saturday, November 8th, and after careful consideration made the following suggestions:

1. In order to have a definite basis on which to work in the planning of Contests of this kind, it is necessary to have a set of rules and regulations that will outline the general government of such Contests, therefore, the following tentative schedule is offered.

Tentative Rules and Regulations for the Government of an Annual Intercollegiate Students’ Poultry Judging Contest

1. This contest shall be known as the Intercollegiate Students’ Poultry Judging Contest.

2. This Contest shall be in charge of a Committee appointed by the President of the American Association of Instructors and Investigators in Poultry Husbandry.

3. It shall be held annually in connection with a well-known Poultry Show, on such day of the show as shall be convenient to the Management …

Report of a Cooperative Conference

During the last week of October and the first week of November, 1919, a cooperative poultry conference was held at the International Egg Laying and Breeding Contest at Vineland, New Jersey. Representatives of the Poultry Departments of four of our Eastern Colleges and Experiment Stations participated. The persons in attendance were Prof. W. R. Graham of the Ontario Agricultural College at Guelph; Dr. O. B. Kent of Cornell University, Ithaca, N. Y.; Prof. W. F. Kirkpatrick and Roy E. Jones of the Connecticut Agricultural College at Storrs, Conn., and Prof. H. R. Lewis and Mr. Victor G. Aubry of the New Jersey Agricultural Experiment Station, New Brunswick, N. J. This conference was held at the invitation of Prof. H. R. Lewis of the New Jersey Agricultural Experiment Station, the object being to study in great detail the yearling hens at the Vineland Contest, especially to …

We were unable to find any experimental data bearing on the subject of the position of the yolk of the egg at the time it is laid or of the position of the yolk at any subsequent time. This induced us to try two series of experiments to decide in our own minds if turning egg while saving them for sitting purposes was really necessary.

On June 24th, 1919 24 eggs were selected from trap nests of Single Comb White Leghorns. Two eggs were boiled at the time the eggs were collected and these eggs sectioned transversely to determine the location of the yolk. We also experimented to see if suspending them in a wire basket in boiling water would coagulate the albumin equally on all sides and not make a possible disturbance within the egg while boiling and dislocate the yolk. All of our tests lead us to think …

The factors which cause high mortality of chick embryos during the period of incubation are more or less obscure. Results obtained at the Massachusetts Agricultural College demonstrate that mortality is not evenly distributed throughout the 21 days of incubation.

For the past three seasons we have kept accurate records of the daily mortality from a portion of the eggs incubated at the College plant, and there has been a marked similarity in the death rate with certain periods of incubation.

The mortality by days was determined in the following manner. A number of eggs were placed under hens, and an egg with a normal embryo was broken every twenty-four hours from the first to the twenty-first day, and the embryos were mounted in glass jars. The dead germs taken from the incubators on the 7th, 14th, and 22nd days were broken, except the blood rings, and the dead embryos were …

A ration for growing chicks must carry a certain amount of protein in order to secure normal growth. This protein may be either animal or vegetable. Animal protein is preferable and there are a greater number of these to choose from, while the desirable and available vegetable protein concentrates are very limited. Soybean meal may be mentioned as one which may substitute, or at least partially substitute animal protein in the ration for growing chicks.

When more than the minimum amount of protein required for normal growth is used in a ration the results secured from the excess does not warrant its use from the standpoint of economical feeding. There is, however, a wide range in the amount of protein which may be used in the ration with about equal results. A considerable excess may not prove harmful but it is better to substitute this excess with the less expensive …

That the Annual Meeting is going to the Pacific is agreed by mostly everyone East of Chicago. Many of us know but little of the condition of the middle West or the far West, and perhaps less of the Canadian. We believe our business is of importance all over the Continent. The expense of going to the coast will be considerable. It is perhaps a long way from home but the Western members have favored us with their presence on several occasions.

Recently we have added to the meetings a Judging School. Why not try a travelling school? Say we start some-where West of New York State and ask the members of each College on the line to Oregon if he so desires to run a one-half day Judging School. The balance of the day we could spend at the College and become acquainted with local problems. Also many of …
