CONDIMENTAL STOCK FOODS 



Condimental stock foods or feeds, sometimes called 

 proprietary stock foods, are usually mixtures made up of 

 one or inore common feed stuffs like wheat bran, wheat 

 middlings, linseed-oil meal, dried blood, cottonseed meal, 

 with a base, filler, or diluent of grain screenings, ground 

 oat hulls, corncob meal, peat or peanut hulls, to which 

 have been added certain condiments, herbs, and drugs, 

 such as common salt, Epsom salts, Glauber's salts, gentian, 

 charcoal, ginger, fenugreek, anise, saltpeter, copperas, 

 as "tonics," "regulators," "appetizers," "conditioners," 

 and so on.^ 



Experimental feeding trials. 



In view of the fact that the manufacturers of these 

 products make large claims concerning their value when 

 fed in rather minute quantities with the regular rations, 

 and due to the fact, also, that their cost is high and their 

 use quite common, a detailed study was made of all 

 American and Canadian pig-feeding experiments in which 

 various brands of stock-foods had been fed. In all, eight 

 experiments have been made which involved the use of a 

 total of 261 pigs averaging approximately 110 pounds 

 when the trials began. The experiments were conducted 

 under dry-lot conditions, excepting those made at the 

 South Dakota Station. In two of these trials the pigs 

 had access to limited areas of rape, and in one, both 

 groups of pigs were on blue-grass. The length of the 

 average feeding period was 77 days. The stock foods were 

 purchased on the open market and fed in each case 

 according to the manufacturer's directions. In Table
