PROGRESSIVE SHEEP RAISING 



Pancreatin, another medicine, is made from the pan- 

 creatic gland, and still another from the mammary glands. 



The thyroid gland (seat of goitre in humans) yields an 

 important medicinal product. 



A class of oleo oil is made from the better grade of 

 mutton tallow, and enters into the manufacture of oleo- 

 margarine. 



Inedible greases are used in soaps. An important by- 

 product of soap-making is glycerin, which is in great 

 demand for the manufacture of nitro-glycerin and other 

 explosives and war munitions. The blood, dried and 

 ground, makes calf feed and fertilizer. Hide trim- 

 mings make glue. Bones and other waste make tankage 

 and fertilizer. 



The complete utilization of all by-products of the sheep 

 and other meat animals has been found practicable only 

 in the largest packing plants, and is one of the triumphs of 

 large-scale operation. It is made possible by two con- 

 siderations the comparatively recent development of 

 large-scale refrigerative control of highly perishable by- 

 products and the enormous volume of those by-products 

 handled. 



This wholesale utilization of by-products brings about 

 a number of important economic results of benefit to the 

 whole country, among which may be mentioned: 



1 . The increased price which the packer is able to pay 

 the farmer for his sheep and other live stock; 



2. The more uniform and perfect meat which the large 

 packer is able to sell the local butcher at a lower cost than 

 that at which he could buy and kill it locally for himself; 

 and 



3. The employment of thousands of persons in the 

 manufacture of these by-products, many of which would 

 otherwise be discarded as of no value by the farmer 

 himself or local butchers, who are even yet throwing them 

 away as of no commercial value.
