ral weeks. It would seem from these
facts, together with the fact that during the experiment the
nitrogenous fed hens laid more than three times as many eggs, that a
nitrogenous ration stimulates egg production.
THE RESULTS OF SLAUGHTERING.
On November 27 the fowls were slaughtered. Each fowl was weighed,
wrapped in a bag to prevent floundering, and killed by severing an
artery in the roof of the mouth. The blood was caught in a glass jar.
The fowls were then picked and the feathers weighed, after which the
body was laid open longitudinally by cutting alongside the sternum and
through the back bone. When all had been thus prepared, they were hung
up in groups to be photographed, but the photographs were quite
unsatisfactory so far as showing the relative proportions of fat and
lean. The accompanying drawing made from the photograph shows the
relative development of an average pair of chickens. Attention is
particularly called to the thighs.
[Illustration]
One-half of each fowl was tested by cooking for flavor, succulence,
and tenderness. The other half was carefully prepared for chemical
analysis by separating the meat from the bones. The flesh was
thoroughly mixed and run through a sausage cutter, mixed again, and
the process repeated three times. From different parts of this mixture
a large sample was taken, from which the chemist took his samples for
analysis. The right tibia of each fowl was tested for strength by
placing it across two parallel bars and suspending a wire on its
center, on which were placed small weights until the bone gave way.
