DAIRY INSPECTION 153 



tory movements is a symptom of disease, except when it occurs 

 after exercise. A decrease in the intensity or depth (shallow 

 respiration) is observed in pleurisy and in painful conditions 

 of the chest wall. 



5. Udder. Examine the udder by inspection. This 

 can be done best when the udder is full. Compare the 

 form and size of the different quarters. Look for swell- 

 ing (mastitis), atrophy, furuncles (feed boils), altera- 

 tions of cowpox, etc. 



6. Appetite. Look into the manger and see if the 

 feed has been eaten and note if the animal is ruminating. 



7. Muzzle and Nostrils. Touch the muzzle and 

 determine the degree of temperature and moisture. Ex- 

 amine the nostrils for pathological discharges. 



The muzzle is dry and sometimes roughened in fever and 

 diarrhea. It is alternately hot and cold in fever, and cold and 

 dry in low conditions endangering life. Vesicles occur on the 

 muzzle in foot and mouth disease. 



A discharge from the nostrils occurs in exudative diseases of 

 the respiratory tract, but in tuberculosis the discharge is 

 frequently not present because the exudate is usually coughed 

 up and swallowed. A nasal discharge may escape notice in 

 cattle because it is generally licked off with the tongue. It is 

 most likely to be seen after coughing. A slight mucous dis- 

 charge is normal. 



8. Submcuvillary and Peripharyngeal Regions. At- 

 tempt to palpate the submaxillary, parotid, retropharyn- 

 geal and atlantal lymph glands ; they cannot be felt unless 

 enlarged. 



The submaxillary lymph-gland is situated within the pos- 

 terior angle of the lower jaw, between the sternocephalicus 

 (sternomaxillaris) muscle and the submaxillary salivary gland.
