pasture. During this time the four steers having only alfalfa 

 gained 127 pounds more than the other four. 



For sixteen weeks alfalfa hay was fed against combinations 

 of alfalfa hay with corn fodder, Kaffir corn or sorghum, during 

 which time the four animals receiving the other feeds in combi- 

 nation with alfalfa gained 59 pounds more than those having 

 alfalfa only. 



During the thirty-three weeks that alfalfa only was fed against 

 combinations of alfalfa and other forages, the animals having only 

 alfalfa gained 1.55 lbs. per day while those receiving the combi- 

 nation gained 1.46 lbs. per day. 



In May a car load of range cattle was purchased of Col. H. 

 C. Hooker of Willcox and with them experiments along this line 

 will be continued. 



THE DAIRY HERD. 



On June 19th, 1900, six two-year-old heifers of unknown 

 breeding were purchased. They had all been bred to calve at 

 from eighteen to twenty-four months of age, had been in milk 

 for about six weeks when purchased and were in very poor con- 

 dition. Since their purchase the milk from each cow has been 

 weighed and tested for butter fat and a record kept. During the 

 year for which the record is given below the only feed received 

 by the cows other than pasture was hay during the last two 

 weeks in September and first two weeks in October, and sugar 

 beets for two weeks in November and December. For three 

 weeks in July and two weeks in August and September, instead of 



Notes. — At the close of the last experiment the eight steers referred 

 to above were sold to a San Diego buyer for Christmas beef at $4.30 per 

 cwt., $3.75 and $4.00 being the prevailing prices at. the time. 



These steers were from ten to fourteen months old when purchased 

 and during the year fed gained 3817 lbs., an average of 477 pounds. 



Steers No. 2 and No. 6 made the greatest gain— 503 lbs. each — while 

 steers No. 7 and No. 8 made the least gain — 448 lbs. each. 



Steer No. 6 made the greatest per cent gain over his original weight 

 — 82 per cent — No. 8 being second with 78 per cent gain. 



Steers Nos. 1 and 5, the oldest and heaviest animals, ranked third and 

 fourth in pounds of gain, and seventh and eighth in per cent of gain.
