34 Report or DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
the different dried ground animal by-products. These consisted 
of “meat meal,” “animal meal,” dried blood, bone meal and 
milk “albumen” (a by-product from the milk sugar factories). 
The ducklings in both lots were of somewhat inferior and weaker 
stock and those of lot “A” also late hatched, but at no time did 
any of them seem to suffer at all in health under the unusual 
ration. 
The foods had the composition shown in the following table:

RATIONS. 
In the rations for both Lot A and Lot B during four weeks of 
feeding, 94 per ct. of the dry matter of 98 per ct. of the protein 
came from animal foods. During the last month for Lot A and 
the last fortnight for Lot B these foods supplied over 90 per ct. 
of the dry matter and nearly 97 per ct. of the total protein. In 
the ration for Lot A about 24 per ct. of the dry matter was repre- 
sented by the ash constituents and in that for Lot B about 29 
per ct. The nutritive ratio was excessively narrow. 
RESULTS. 
The birds in Lot A made a fairly rapid growth during four 
weeks without waste of food. During the next month growth 
was slower, and unprofitable. Lot B of older birds made good 
gains at fair expenditure of food during four weeks. For two 
weeks following there was slow increase in weight as is usual 
with birds of this age. Profitable growth would hardly be 
expected owing to the expensive foods used, but for a month with 
each lot the cost was not excessive, although the average cost 
of gain in weight was high.
