After the average person gets used to the idea of the use of artificial light to increase egg production, the first or main prejudice commonly met with is that it is a forcing process; that it means overworking the hens and therefore must result, sooner or later, in an injury to them, or in their physical breakdown. The welcome fact is that this…

This bulletin contains an account of investigations in breeding poultry for egg production; the methods employed in the selection of breeding stock; and detailed accounts of the methods of feeding hens and chickens.

This Bulletin contains an account of breeding for egg production, including the egg record of the breeding pens for 1902; experiments upon the amount of floor space and other conditions of housing in relation to egg yields ; and experiments in incubation of eggs.

We hear a good deal said in these days about the 200 egg hen. Some are disposed to deny her existence, and to class her with such fabulous or semi-fabulous birds as the phoenix and dodo. Others admit that she has appeared in isolated instances, but is by no means common. Others contend that if she should appear in large numbers it would be a…

"Here everything but an egg is a by-product."

These words of Edward Corning hold the secret of the great success of the Corning egg farm. That little farm, with its immense product of "fancy" eggs, is a capital illustration of the great possibilities of specialization when applied to poultry products. The great demand in large cities for a…

We have endeavored to obtain for the readers of Eggs and Egg Farms the latest trustworthy information in reference to this important and profitable branch of the poultry industry. Almost every person is in a position to make money by keeping a few fowls to supply the daily egg needs of the home table, or a greater number to satisfy the appetites of…

Few subjects have been so much discussed as that of raising chickens. There are grounds for supposing that the first thing Adam and Eve did after their investigation of the forbidden brought up the problem of the high cost of living was to turn to the hen for a solution.

One of the most important advance steps in commercial poultry keeping in recent years, and one that promises to exercise a truly great influence upon the development and permanent upbuilding of the industry, is the more exact knowledge poultry keepers now have of the characters of individual fowls; also the extent to which these characters, whether…

For many years poultry work has been carried on at the University of Maine. It was not, however, until 1897 that the Maine Experiment Station decided to begin a series of poultry investigations on a somewhat extended scale. Since 1904 this work has been carried on in cooperation with the Bureau of Animal Industry of the United States Department of…

The Egg Safety Action Plan released in 1999 raised many questions concerning egg temperature used in the risk assessment model. Therefore, a national study by researchers in California, Connecticut, Georgia, Iowa, Illinois, North Carolina, Pennsylvania, and Texas was initiated to determine the internal and external temperature sequence of eggs from…

The Egg Safety Action Plan released in 1999 raised questions concerning egg temperature used in the risk assessment model. Therefore, a national study was initiated to determine the internal and external temperature sequence of eggs from oviposition through distribution. Researchers gathered data from commercial egg production, shell egg…

During Egg Safety Action Plan hearings in Washington, DC, many questions were raised concerning the egg temperature (T) used in the risk assessment model. Therefore, a national study was initiated to determine the T of eggs from oviposition through distribution. In part 1; researchers gathered data on internal and surface egg T from commercial…

Restricted shell eggs that do not meet quality standards for retail but maintain acceptable quality for inclusion in further processed eggs are often diverted to further processing. A study was conducted to characterize the microbiological populations present on and in these eggs. On a single day, restricted eggs were collected from three shell egg…

The dopaminergic system is involved in the regulation of aggression in many species, especially via dopamine (DA) D1 and D2 receptor pathways. To investigate heritable differences in this regulation, 2 high aggressive strains [Dekalb XL (DXL) and low group egg productivity and survivability (LGPS)] and one low aggressive strain (low group egg…
