c) Snake bite<br />

Venormnous snakes fall in to 2 classes: the elapine snakes which include cobra and the<br />

viperine snakes which comprise Russels viper, Elapino snakes have short fangs and tend to<br />

chew their victims. Their venom is neurotoxic and kills the victim by paralysing the<br />

respiratory centres. Viperine snakes attack once and then withdraw . Their venoms mainly<br />

haemolytic causing pronounced local damage.<br />

Experimental work suggest an order of decreasing sensitivity is horse, sheep, ox, goat, dog,<br />

pig and cat. <strong>Sheep</strong> is usually bitten on udder or scrotum. The presence of hair may abscure<br />

the typical fangs marks though a close examination should reveal the point of entry. Prolonged<br />

pain, muscular weankess, impaired vision, nausea, paralysis are generally exhibited. Shock in<br />

all its classical elements accompanies all severe snake bites.<br />

If antivenin is not available and the bite is located in an area where tourniquatus cannot be<br />

applied excision of an area of skin, 7 cms. in diameter, including the associated sub-cut tissue<br />

may be life saving. Normally no treatment is possible due to sudden death in grazing areas.<br />

d) Electricution<br />

One of the natural calamity where death ensues in few seconds. Common couses are short<br />

circuit in electric line, leakage of current in wire fencing.<br />

The animals are generally found dead with eyes wide open and pupil dilated. The anus<br />

may also left dilated with some faecal material voided out. On autospsy haemorrhages of<br />

varying size are observed under the skin and viscra. Heart may show streaks of haemorrhages<br />

on myocardium with pin point haemorrhanges. The blood may appear black and liquified.<br />

This needs to be differentiated from lightening stroke when there is no evidence of lightening<br />

fall and no signs of scrarching and sinking of skin and hairs on the body of the animal.<br />

e) Wouds<br />

During monsoon season, a large number of animals suffer from wounds at various sites.<br />

Around the ear, sternum, under surface of fore and hind legs are usual places. The main reason<br />

may be the awns of Aristida and Hetropogan grasses, which initially break the continuity of<br />

skin which is attacked by flies making the wound infected and maggoty. Antiseptic dressing<br />

with fly repellents, i.e turpentine with chloroform is applied over the wound and adjacent area.<br />

As the weather changes the incidence is also reduced.<br />

Grass seed infestation viz. Hetropogan controtus and Aristida sp. play a vital role in<br />

certain areas in the production of stress in young lambs with consequent ill effects. Abcess<br />

formation specially on various places at head and legs are not uncommon. It causes<br />

conjunctivitis, opacity of cornea and blindness.<br />

f) Dystokia (Caesarean operation)<br />

Common causes are insufficient opening of cervical canal, heavy lambs specially<br />

crossbreds, position of embryo, uterine torsion. The pregnant ewe should not have fever and<br />

the operation should be conducted at a clean place on clean table.<br />

Skin of the near about area is to be cleared and shaved with soap water and on cleaned<br />

area Tricture iodine or similar antiseptic prepaation should be applied.<br />

2% Novocain is the best anesthesia which can be used. Left or right flanks can be used.<br />

Right side is better because, rumen is not an obstacle and uterus will be found immediately<br />

after opening 20-25 cm. long incision leaving 3 fingers from tubercoxae directing towards<br />

knee joint. The impregnated horn should be lifted towards the opening and uterus should be<br />

opened taking care that no embryonal water should go in the peritioneal cavity. Alive lamb<br />

should be cared by an helper, who should clean it. The umbilicus should be cut nearnest to<br />

endomestrium and uterus should be closed keeping sufficient antibiotic, specially terramycin<br />

and closed though catgut. Skin should be sutured separately with muscles. Muscles can be<br />

sutured with intermittent sutures putting sufficient antibiotic to aviod any sepsis. For 3-4 day,<br />

antibiotic should be given parentrally also.<br />
