FIG. 3. Plymouth Rock Hen 

 with high record yield. 



3. The Asiatic or Meat breeds. 



(a) Brahmas. 



(b) Cochins. 



(c) Langshans. 



4. The English breeds. 



(a) Dorkings. 



(b) Orphingtons. 



(c) Redcaps. 



The Leghorns lead in the 

 production of eggs. 



The Plymouth Rocks are 

 the best general purpose breed. 

 The Brahmas are the best 

 meat producers. 

 In all cases whether breeding for egg production, general 

 purposes or for meat, pure bred poultry means uniformity of 

 products, better prices and increasing profits. 



Feeds and Feeding for Poultry. 



A chemical analysis of the laying hen and of a fresh egg 

 shows the following composition : 



Water. Protean. Fat. Ash. 



Laying hen 55.8 ^Percent 21.6 17 3.8 



Fresh egg 65.7 11.4 8.9 12.2 



It has also been determined by conclusive experiments that 

 hens in full laying should have the following digestible nutriments 

 per day for each 100 pounds of live weight : 



Dry Carbo- 



M alter. Protein, hydrates. Fat. Ash. 

 pounds. 



(a) Hens of 3 to 5 pounds weight 3.3 0.65 2.25 0.2 0.2 



(b) Hens of 5 to 8 pounds weight 5.5 1.00 3.75 0.35 0.3 



PROBLEMS. 



1. Find the nutritive ratio of the composition of the laying hen. 



2. Find the nutritive ratio of a fresh egg. 



3. Find the nutritive ratio of each of the feeds given above. 



4. What is the average nutritive ratio of the two feeds (a) and (b) 

 for laying hens?
