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. Submacillary and Peripharyngeal Regions.—A- 
tempt to palpate the submaxillary, parotid, retropharyn- 
geal and atlantal lymph glands; they cannot be felt unless 
enlarged. 
The submazillary lymph-gland is situated within the pos- 
terior angle of the lower jaw, between the sternocephalicus 
(sternomaxillaris) muscle and the submaxillary salivary gland.
