Flashcards in FAC34: Bovine Teat Diseases Deck (29):
1

What are the different types of bovine teat diseases?

Infectious of the teat SKIN

Non-infectious of the teat

Teat injuries/obstructions

2

What does papillomatosis look like?

Warts - rice grain type or more florid projecting warts

3

What makes papillomatosis a difficult milking disease?

It acts as a mechanical interference with milking and harbour bacteria

4

How do you treat teat warts?

Self-limiting in most cases, but you can ligature or rubber ring or snip off, or cryosurgery

5

What virus is responsible for herpes mammillitis?

Bovine herpesvirus 2

6

What makes herpes mammillitis difficult for milking?

The cow develops vesicles then ulcers which are painful and made worse by milking machinery

7

How do you treat herpes mammillitis?

Treat symptomatically with udder cream and control spread by parlous hygiene using iodophor based teat dips

8

What is the aetiology of pseudocowpox?

Parapoxvirus

9

Is pseudocowpox zoonotic?

Yes

10

What does pseudocowpox look like?

Raised papules then healing scabs

11

How do you treat pseudocowpox?

None. Control through parlour hygiene and teat disinfection

12

What is another name for udder impetigo?

Necrotic dermatitis

13

What is necrotic dermatitis caused by?

Staphylococci spp and is associated with poor environmental conditions or skin trauma (allowing the infection)

14

How do you treat udder impetigo?

Based on cleaning and topical application of antiseptic udder cream or occasionally systemic antibiotic

 

May be secondary to udder oedema

15

Which cows usually get udder oedema?

Primiparous heifers close to calving

16

How do you treat udder oedema?

Usually resolves when lactation starts

If it doesn't, induce with corticosteroids

17

What are teat chaps?

aka Summer sores

Traumatic lesions caused by poor milking machine function or in beef cows - aggressive suckling

Flies will exacerbate the lesions

18

How do you treat teat chaps?

Symptomatic topical treatment, remove cause, and manage against flies

19

What causes hyperkeratosis?

Caused by poor milking machine function and can be risk factor for mastitis

20

How do you measure the degree of hyperkeratosis?

Teat end scoring

21

What is the cause of blackspot?

It is a secondary infection caused by fusibacterium necrophorum

22

How do you treat teat lacerations?

Most are treated conservatively with topical creams but surgery can be attempted if it is a FRESH WOUND

23

Why should treating a teat end injury be done with lots of consideration?

There is a high risk of developing mastitis 

24

How do you treat a teat end obstruction caused by a flap of skin?

Use sterile hypodermic needle or teat knife - may need canula inserted while healing

25

What are the different types of acquired teat obstructions? What causes them?

Caused by mucosal proliferation/granulation

Teat peas/floaters or Pencil Obstruction 

26

How do you treat a teat pea?

Enlarge teat orifice and squeeze

Use teat instruments

27

What are the infectious causes of teat diseases?

Papilllomatosis

Herpes mamillits

Pseudocowpox

Bluetongue

Cowpox and vesicular stomatitis

Udder impetigo

Necrotic dermatitis

28

What are some non-infectious disease of teat skin?

Udder oedema

Photosensitisation

Teat chaps

Milking machine induced lesions

Teat lacerations

Teat cistern obstructions

 

29

What is the cause of a pencil obstruction?

Follow diffuse teat trauma leading to a chronic granulomatous reaction of the teat mucosa. Milk will only flow in a very small amount and a firm pencil like obstruction can be palpated in the teat cistern.
