EXPERIMENT STATION RECORD. 



In a test In which peas and oats, alfalfa, mixed grasses, and clover were 

 compared as supplements to a grain ration it was found that the peas and oats 

 pasture made a relatively good showing. The mixed pasture was found to be 

 not so valuable. 



In the hogging off of peas one lot containing 1.32 acres was used for 25 days 

 by 20 pigs averaging 78.5 lbs., a second lot of 1.42 acres for 38 days by 20 pigs 

 averaging 84.8 lbs., and a third lot of 1.51 acres for 30 days by 15 pigs averaging 

 54.7 lbs., and for 44 days by 30 pigs averaging 70.8 lbs. Figuring pork at $6.00 

 per 100 lbs., the peas produced an average return of $25.53 per acre or $2.13 

 per 100 lbs. of peas in the field. In this experiment the second lot was fed 

 rolled barley as a supplement at the rate of 2 lbs. per 100 lbs. of live weight, 

 but the results did not justify the additional labor. 



The following table is compiled from four years' weights of fleeces, two years' 

 records of weights of ewes, weights of lambs at birth, and daily gains of lambs, 

 and a single season record on relative breed maintenance.

[Live stock experiments] {Xcw Mexico Sta. Kpt. 19 io, pp. 69-79). — In an 

 experiment witli four lots of 8 pigs each, in which lot 1 was given a full con- 

 centrate ration, lot 2 a part concentrate ration in the proportion of 1 lb. con- 

 centrate to 100 lbs. live weight, lot 3 a concentrate and dried beet pulp ration 

 in the proportion of 1 lb. concentrate and 0.5 lb. beet pulp to each 1(K) lbs. of 

 live weight, all of the lots receiving as much choice alfalfa hay as they would 

 eat, the results favored the feetling of a full ration. The addition of beet 

 pulp to the ration increased the gains 20 per cent, but this was not enough to 

 pay for the increased cost. 



Two lots of pigs were fed an allowance of 2 lbs. of concentrate for each 100 

 lbs. live weight, lot 1 receiving in addition all the corn silage and lot 2 all 

 the alfalfa hay they would consume. The results of this exiieriment were In 

 favor of alfalfa hay, both in gains and cost of gains. 



In an experiment to determine what use may be made of crops grown under 

 dry-farm conditions for feeding range steers for beef one lot of steers was fed 

 entirely on dry-farm crops, making use of cowpea hay to furnish the protein 

 necessary to balance the ration properly. The other lot was given an allow- 

 ance of cotton-seed meal in place of the cowpea hay. Both lots were fed silage 

 made of milo maize and Katir corn, and both had an allowance of ground niilo 

 maize and Kafir-corn heads, but the roughage fed to one lot was shreddeil 

 milo maize fodder and to the other cowpea hay. The results for 76 days show 

 quite marke<lly in favor of the cowpea-hay fed lot, in both daily gains and cost 

 of gains. The average dally gain per head of the co\ATea-hay fed lot was 

 2.86 lbs., while with the cotton-seed meal lot it was 2.4 lbs. 



In continuation of a nutrition project, begun several years ago, calves and year- 

 lings, 2-year-olds and 3-year-olds, were fed for 120 days on alfalfa and milo-maize
