PASTURING ALFALFA SUPPLEMENTED WITH MIXED CONCENTRATES. 
It is not an uncommon practice among swine growers on the irri- 
gated lands to feed hogs mixtures of two or more grains or of: one 
grain and some other feed. In this way use is made of swine in 
utilizing materials which are not readily marketable or which other- 
wise would be wasted. Table XIII contains data from 13 lots of 
pigs to which mixed concentrates were fed as supplements to alfalfa 
pasture. All these lots had an excess of pasture except Nos. 10 and 
11, which grazed 1 acre, and Nos. 12 and 13, which had access to 0.4 
of an acre of pasture. Lots 1 to 8, inclusive, were on farms on the 
North Platte Project; lots 9, 10, and 11, on the Uncompahgre Proj- 
ect; and lots 12 and 13, on the Truckee-Carson Experiment Farm. 
Taste XIII.—Results secured with 13 lots of pigs on irrigated alfalfa pasture 
supplemented with mired concentrates on three reclamation projects.
