PROBLEM. 



If an experiment showed that 770 chicks weighed 61 pounds at hatch- 

 ing time, and 140 pounds at the end of two weeks, about how long does it 

 take for chicks to double in weight? 



Questions. 



1. Why does the young bird in growing require food containing 

 more phosphorus than a mature fowl? 



2. Why do growing chicks require more feed in proportion to their 

 size than growing claves ? 



3. How old must a colt be to double its weight? a lamb? a young 

 rabbit? 



PROBLEM. 



1. If a colt will double its weight in 60 days and a chick will double 

 its weight in 10 days, how many times greater is the process of digestion 

 and assimilation in the chick than in the colt? 



The New York Experiment Station has determined certain 

 feeding 1 standards for poultry, of which the following is taken 

 for chicks : 



POUNDS. 



Dry Carbo- Nutritive 



Matter. Ash. Protein, hydrates. Fat. Ratio. 



The above are the digestible nutrients per day for each 100
