REPORT OF THE ANIMAL HUSBANDRY SECTION. 



Director R. S. Shaw, 



Dear Sir : 



I have the honor to submit the following report of the experimental work 

 conducted by the Animal Husbandry section during the past year. 



Another year's work on the use of stover silage for fattening steers has been 

 concluded. The work this year embraced three lots of steers. Lot 1, was 

 fed normal corn silage as previously, lot 2, stover silage, and lot 3, stover silage 

 plus an amount of corn equal to that which was removed from the stover 

 when it was placed in the silo. Lot 1 made an average daily gain of L94 

 pounds; lot 2, L42 pounds and lot 3, 1.58 pounds. Not only was the gain 

 greater in lot 1 but the cost was much lower in lot 1 than in the other two lots, 

 both of which averaged about the same in cost. The results this year were 

 decidedly in favor of placing the corn in the silo along with the stover or 

 the making of normal silage. Plans are already under way for the repetition 

 of this work the coming winter. It is earnestly hoped that before another 

 year facilities will be added to our equipment to permit the handling of a 

 much larger number of steers, as the feeding of one carload in our present 

 quarters greatly overcrowds the beef breeding herd, and a single carload of 

 steers does not provide a sufficient number of animals to work out the various 

 angles entering into the question of the use of stover silage. 



The experimental work with pig feeding as reported last year is being 

 repeated, as we felt that the amount of grain required to produce 100 pounds 

 of pork as shown in the tests reported was rather large, and an effort is being 

 made to discover if there is any reason for this. The tests will be repeated 

 twice, making five trials in all before the work is reported on, which we think 

 will be sometime early next spring. 



Respectfully submitted,

 Professor of Animal Husbandry.

REPORT OF THE ANIIMAL PATHOLOGY SECTION. 



Directors R. S. Shaw, 

 Dear Sir: 



I herewith submit the report of the Animal Pathologist for the year ending 

 June 30, 1921. 



Two problems have been studied the last year, namely, the pathology of 

 pyometra in cattle, and the effects of medicinal agents on the uterine mucosa 

 of the cow. 



A report of this work has been submitted for publication as Technical Bul- 

 letin No. 54, and a detailed discussion here would be unnecessary repetition. 

 Briefly, it may be said that pyometra is a common and serious sequel of 

 abortion infection and is characterized by a jDurulent inflammation of the
