DAIRY HUSBANDRY 



W. S. Cunningham, R. N. Davis 



The outlook for dairying in Arizona is much brighter than 

 it was a year ago. The industry is reviving in the Salt River 

 Valley, where many dairy herds were disposed of in 1918, 1919, 

 and 1920, and it is expected that there will be a large increase 

 in the number of cows in that valley during the next year. 

 Dairying is also becoming a major industry in Cochise, Pima, 

 Pinal, Graham, Navajo, and Apache counties. 



One Jersey cow, Aldan's Oxford Nora, and a Jersey bull, 

 Oxford Nora's Fox, have been added to the Jersey herd at the 

 University Farm. A well-bred Holsteirl-Friesian bull, Change- 

 ling Pontiac De Kol, owned by B. Coman of Phoenix, was loaned 

 temporarily to the University. 



A number of the Holstein-Friesian cows on the University 

 Farm were tested officially for Advanced Registry during the 

 year. The following official records were made:

The above named Holsteins and one Jersey, Arizona's But- 

 ter Girl, No. 378677, are on semi-official test. The other cows 

 in the herd will be put on semi-official test during the present 

 year. 



Daily records were kept of the milk yield of all the dairy 

 cows, and a two-day composite sample of milk was tested each 

 month to get an estimate of the fat production. This report 

 covers the period from July 1, 1920, to June 30, 1921, and does 

 not give the production for exact lactation periods. Some of the 

 cows were dry for a portion of the year. Table V. gives 

 the milk and butterfat production for the fiscal year.
