Thus,despite an obvious preference for coarsely ground grains, laying hens are appar-ently adaptable and will quickly adjust themselves to rations of different texture with little cUcci on egg production. Unless the Iced is so finely ground as to tend 43 to become pasty, the degree of grinding of the ration does not appear to be animportant factor in egg production, so that feeds varying in texture may be safelyfed to laying Figure 12. Metabolism cages such as this provide information onthe digestibility of poultry feeds. Lobster Meal for Growing Chickens Lobster meal is manufactured from the lobster waste from lobster canningoperations. It is prepared by drying and grinding this waste material. It isfairly high in protein (about 35 per cent) but is also high in ash (about 25 per cent).Substantial quantities of lobster waste are available from Maritime lobstercanning factories for conversion into meal. Feeding trials.—A number of feeding trials have been carried out to test thevalue of lobster meal as a source of protein for growing chickens. Results ofthese tests indicate that when fed in moderate amounts with fishmeal, lobstermeal may be used as a source of protein. However, the high ash content hasa depressing effect on growth if too much lobster meal is included in the present it is not recommended that lobster meal be used as the only source ofanimal protein. It should b
