I WILL EATEN YOUR COWS
 TUCSON. March a7.-Under the di-
 rection Of the Animal Husbandry De
 pertinent of the University of Arizona
 an experiment. has been conducted on
 the Cochise Dry Farm with four lots
 of COWS and one lot of calves This
 experiment covering a period of IF
 weeks has just been completed. The
 cows were all given 2s5 pounds of cottonseed meal per head daily. sup piemented with silage. fodder and dry pasture. The cows fed sweet sor- ghum silage as a supplement. gained most-averaging ? 1-4 pounds day |, The lot receiving sunfiower silage gained little under two pounds. and the COWS fed sweet sorghum fodder. as well as the calves given sunflow- CT silage. gained an average of 34
 
 range of dry pasture and 1-2 pounds or meal only gained l-2 pound per day
 The cost of gains varied from ten cents per pound for calves, to near fourteen cents with the cows on the dry pasture. Not much difference was noted between the cost of gains in the COWS. The lot receiving sweet sorghum silage as roughage gained one pound at a feed cost of ten cents; those on the fodder eleven cents. and the cows given sunfiower silage cost thirteen cents for every pound gained.
 The calves have been sold to the butcher at 6 l-2 cents per pound and they will weigh around 5s0 pounds. They will make about sS.0o profit per head The highest offer has been { l-2 cents for half fattest cows. The cows receiving the sweet sorghum silage were the fattest. indicating that this roughage is superior to the sun flower silage. The cows fed on fod- der were also fatter at the end of 12 weeks. although they had not gained as much as the cows given sunflower silage. On the other hand. the cows allowed 1-2 pounds of cottonseed meal and free range of dry grass made very little gain. They were strong but did not get fat. and could not be sold for more than they cost when the test began.
 This test proves that old. thin, range COWS can be fattened on the or dinary dry farm roughages, either fod- der or silage, if given to 3 pounds of cottonseed meal daily Previous tests indicate that thin, range cows will take good fill on silage alone over the first three weeks. but w.E not fatten unless given more than si- lnge. The sunflower silage made a very satisfactory feed for COWS along with concentrate rich in protein such as cottonseed meal Calves will make a profit if fed under conditions which obtained this winter On the other hand. thin, old range COWS will not make money if siIage is valued at sS.00 per ton. About the only advau tage from feeding these old COW; .s to be able to market them and the fed grown on dry farms when il is .iiii cult to market old COWS and siiage separately. Many of these COWS would have died on the range during the winter if they had not been given more than the dry grass
 The test is being continued on the COchise Dry Farm, until better of fer is made for the cows. All except the cows on dry grass and six of the oldest and weakest cows are in good condition for the butcher. Several calves have been dropped and a fur ther study is being made of the effect of raising a calf on the cows
