the Effects of Antibiotics in the Laying Ration Upon Egg-Shell Quality.Cadet, C.M.E. January 1954 (has links)
The adaptation of the poultry industry to accommodate the needs of large scale production has resulted in the division of the industry into specialized units of meat and egg production. Egg production constitutes the major phase, from the aspect of both the percent of the total investment in the industry which is devoted to it and the number of flocks that is kept for egg production. It is to be expected then, that research study in the poultry field has until recently been devoted mainly to the problems associated with large-scale egg production. [...]

To maintain this demand, poultry products must exhibit excellent food value and appealing appearance. In dealing with the fresh egg industry the maintenance of superior quality depends to a large extent upon the quality of the shell encasing the egg. Any malformation of the eggshell, while it may not be serious enough to lead to a more rapid deterioration of the contents, detracts from consumer appeal, a necessity in modern sales programs.
