DISEASES FOLLOWING PARTURITION. 253 



This serves to unload the head, by favoring the gravitation backward 

 of its blood, and protects the brain against injurious shocks. 



Cases often recover very quickly. A cow is found up and eating 

 which was down utterly insensible a few hours before. Others recover 

 more slowly, and require careful, restricted feeding and a daily dose of 

 saltpeter and nux vomica for several days. Other complications must 

 be met according to their nature. 



PALSY AFTER CALVING DROPPING AFTER CALVING. 



This consists in a more or less complete loss of control of the hind 

 limbs occurring after calving, and duo either to low condition, weak- 

 ness and exposure to cold, or to injurious compression of the nerves of 

 the hind limbs by a large calf passing through the pelvis. Its symp- 

 toms do not diflTer from those of palsy of the hind limbs, occurring at 

 other times, and it may be treated in the same way, excepting so far 

 as bruises of the vagina may demand special soothing treatment. 



CONGESTION OF THE UDDER GARGET. 



In heavy milkers, -before and just after calving, it is the rule that the 

 mammary gland is enlarged, hot, tense and tender, and that a slight 

 exudation or pasty swelling extends forward from the gland on tho 

 lower surface of the abdomen. This physiological congestion is looked 

 upon as a matter of course, and disappears in two or three days when 

 the secretion of milk has been fully established. This breaking up of 

 the bag may be greatly hastened by the sucking of a hungry calf, and 

 the kneading it gives the udder with its nose, by stripping the glands 

 clean thrice daily, and by active rubbing at each milking witli the 

 palm of the hand, with or without lard, or, better, with camphorated 

 ointment. 



The congestion may be at times aggravated by standing in a draft of 

 cold air, or by neglect to milk for an entire day or more (overstocking, 

 hefting) with the view of making a great show of udder for purposes of 

 sale. In such cases the surface of the bag pits on pressure, and the 

 milk has a reddish tinge or even streaks of blood, or it is partially or 

 fully clotted and i.s drawn with difficulty, mixed, it may l>e, with a yel- 

 lowish serum (whey) which has separated from the casein. This should 

 be treated like the above, though it may sometimes demand fomenta- 

 tions with warm water to ward oft' inflammation, ami it may be a woek 

 before the natural condition of the gland i.s restored. 



INFLAMMATION OF THE UDDER SIMPLE MAMMITIS. 



Congestion may merge into active inflammation, or it may arise 

 direct, in connection with exposure to cold or wot, with standing in a 

 cold draft, with blows on the udder with Hubs, stones, horns, or feet, 

 with injury from a sharp or eold stone, or the projecting edge of a board
