This document discusses various conditions affecting the neck region in working cattle and buffaloes, including yoke gall, abscesses, tumors, and torticollis. Yoke gall is an inflammation of the skin on the neck caused by friction from the yoke. Abscesses in the neck should be incised and drained once mature to release pus. Tumors can be removed through enucleation. Torticollis involves twisting of the neck due to injury. Fistula wither affects horses and results from bursal inflammation between the spine and ligament, often due to trauma from ill-fitting saddles.
Affection and treatment of neck
- 1. Affection and treatment of Neck Dr. Bikash Puri Assist. Professor Nepal Polytechnic Institute, Chitwan
- 2. Yoke Gall • IT is a localized acute inflammation of the skin and subcutis on the dorsum of the neck of working cattle and buffalo bullock due to constant friction caused by yoke. • Incidence: – Draught purpose bullocks and buffalo bulls (i.e. used for carting or ploughing) are more affected. • Predisposing factors: – Rough roads and extra heavy loads. – Young animal with tender necks skin – Force animla to prolong work – A yoke with rough surface – Improper selection of pair of animals
- 3. How does it form? • The pressure of the yoke combined with its movement induces friction causing separation of the layers of the skin and subcutaneous tissue. • This is followed by infiltration of serum and inflammatory exudates • More or less circular diffuse swelling results. The size of the swelling may be small or as large as football. • The moist condition of skin due to sweat or rain favour formation of a gall.
- 4. Clinical symptoms • Swelling on dorsum of neck. • The swelling may be variable i.e may be the size of the cricket ball to as large as football. • Initially, the swelling appears warm and painful. • Swollen mass is soft with fluid inside or hard in consistency on palpation. • Infection leads to abscess formation • Skin flold in region due to diffuse cellulitis.
- 5. Diagnosis • On the basis of history and clinical symptoms • Exploratory puncture confirms for absess, tumor, e
- 6. Treatment • If the condition is of acute type- – Give cold therapy – Paint the swollen area with iodine onitment to facilitates reabsorption of the exudate. – Administer NSAIDS parentrally – Give rest to animal.
- 7. Yolk abscess • If the abscess is immature allow it to mature before being incised to drain the pus. • Maturation of abscess can be achieved by hot fomentation or by of iodine ointment. • Once matured the abscess should be incised at the most dependent part with a knife or scalpel. • Irrigate the pus cavity by hyper tonic saline and dress with antiseptic. • Pack the cavity with moist antiseptic gauge dip into tincture iodine on first day. From next day don’t use tincture iodine as it will injure the newly formed granulation tissue and hence better to use non irritant antiseptic like acriflavin. • Antibiotic therapy for 5 days.
- 8. Tumor neck • Treatment: – Enucleation (or extripation) may be indicated. • Steps: – Prepare the site aseptically after clipping and saving. – Paint the surgical site with ethyl alcohol – Infiltrate local analgesia around the base of the tumor – Make two elliptical skin incision across the swelling . Incision should be slightly oblique rather than longitudinal or vertical to avoid the tendency to gape when animal lowers head. – After incision of skin undermining the skin to reach the base of fibrous mass. – Check the haemorrhage if any and Enucleated the disintegrated fibrous mass completely. – Irrigate with iodine solution and apply topical antibiotic pv. And finally suture the wound with nylon or silk.
- 9. torticollis • Twisting or distortion of the neck is called torticollis or wry neck. The condition has been observed in calves adult cattle, buffaloes and horses. Mostly the condition is seen when animal fall with head and neck under body. • Symptoms; – There may be subluxation of one or more joints of certain cervical vertebrae or spasm of certain cervical muscles. – Presence of unilateral muscle paralysis in the region of neck – The head is kept lowered slightly twisted and turned to one side. – Severe pain in initial stages • Treatment: – Subluxation can be corrected after local inflammation and pain subsides to a certain extend – Use of splint on either side of neck to mmobilize.
- 10. Fistula wither • Results from inflammation of the typical bursae situated between spine and ligamentum nuchae. • Common condition of horses. • Etilogy: • A. Predisposing factors: • The withers of horse does not have massive muscular covering and hence more chance of trauma. • Bad confirmation • B. Exciting causes: • Trauma resulting form an ill filled saddle. • A saddle which is too small or too big may be more traumatic. • In narrow chested animal, the saddle may frequently slip forward and causes trauma. • Infectious: Bacterial infection example: Burcella abortus. • Vitamin E deficiencies.
- 11. Symptoms • A well marked local swelling due to distention of bursa • May or may not be painful to touch • In chronic cases, bursal enlargement may extend into the surrounding tissue in the form of pocket. • In case of bacterial infection the suppurative inflammation occurs and bursa may rupture like an abscess. • The pus escape through small sinus opening on the skin in the region of wither (Hence termed fistula wither) • The pus migrate downwards and spread easily through intramuscular spaces of the external thoracic and cervical muscles and thus pus collect either infront of shoulder or behind shoulder • Suppuration may also extend to neighbouring tissues like: • Ligamentum nuchae • Supraspinous ligament • Cartilage of dorsal spine • Cartilaginous portion of scapula and ribs etc.
- 12. Prognosis • Guarded and require prolonged treatment. • Treatment: • Discontinue the use of saddle • Enlarge the sinus opening to facilitate drainage • Touch the interior with caustics • Remove the necrotic tissue • Drain the pus from the surrounding tissue • Use of antimicrobial both locally and paranterally after sensitivity test.
