ment of these could very well result in an improperly formed giz- 

 zard lining. 



Four feeding experiments were made in which fresh lemon juice, 

 atropin sulfate, arecoline hydrobromide. weak base and acid solu- 

 tions, and cevitamic acid were included in the ration. In one of 

 these experiments, chicks were fed on a ration lacking in Vitamin C. 



The results of these experiments were somewhat contradictory 

 and. until further work can be done on this problem, no conclusions 

 can be drawn. This project is in charge of AT. S. Cover and C. L.

Methods of Administering Medicine to Sheep 



To secure maximum efficiency in administering liquid medicants. 

 sheep should be fasted for at least twenty-four hours previous to 

 the treatment, reports C. L. Martin. When this is done and the 

 medicine is administered to sheep in an upright position, liquid med- 

 icine will follow the esophogeal groove through the rumen and 

 reticulum to the omasum and abomasum. its desired destination, 

 more often than if the sheep are not totally fasted. 



Capsules as a means of giving medicine for stomach worms are a 

 waste of time and money. They go only to the rumen, dissolve their 

 shell, and emjity their contents into the rumen ingesta. By the 

 time this reaches the abomasum, the medicant has lost the major 

 part of its effectiveness. 



This work will be checked further as sheep are ol:)tained. 



Pullorum Eradication in New Hampshire 



A new record for testing the largest per cent of adult birds in any 

 state in the L nion was established during the season 1938-39 under 

 the su])ervision of the New^ Ham]:)shire Department of Agriculture. 

 Division of Animal Industries. Of the total adult birds, 52.5 per 

 cent were tested with 99.8 per cent not reactive. There were 716,- 

 496 blood sam]iles tested for pullorum from 546 flticks, having 

 683.128 chickens, 2,286 turkeys. 40 geese, and 5 ducks, as compared 

 to 549.064 blood samples tested from -142 flocks the previous season. 

 Fifteen new flocks were added to the ])ullorum-clean list, and 5 

 were removed for failure to test, bringing the total to 106. 



The large amount of testing was due to financial assistance given 

 by the Department of .Agriculture toward the eradicatii)n of pullor- 

 um from New Haiui)shire jioultry Hocks. (Miscellnncovs Income) 



Poultry Autopsies 



.\ total of 2.678 autopsies were made during the fiscal vear of 

 19.38-19.^9 by C. A. T.ottorff. C. L. Martin and M. S. Cover. This 

 number involved 731 cases for state poultrymen. For the state 

 work there were 259 chick cases including 1.269 chicks: 4.'34 adult 

 cases, including 901 birds: 38 turkey cases involving 68 turkeys an<l 

 also 3 i)igeons. one song sparrow, one jKirtridge and one swan. 



The leading disease of adults this year was contagious indigestion 

 (blue comb) ; 23 per cent of all cases showed the ])resence of this 

 disease. Ruptin-ed egg yolk was second in importance showing \\\) in
