true

3

Name two NSAID drugs available for food animals.

Meloxicam and Flunixin meglumine

4

Why do we castrate?

Behavior modification, prevent unintended births, improve carcass quality, and pathologic processes

5

What are the basic means of castration?

hormonal, chemical, and physical (non-surgical and surgical)

6

Describe the process of surgical castration of camelids using a newberry knife.

1. Give ketamine/xylazine/butorphanol mixture 2. Give lidocaine locally 3. Use either the newberry knife or a blade at the junction of the middle and distal third of the testicles

7

Post-castration, what should you check for?

bleeding, stretch your incision, look for swelling, infection, hemorrhage, and tetanus

8

True or False: It is best to wait until cattle are over 6 months of age to dehorn

false - it is best if they are under 6 weeks of age

9

When should you utilize paste disbudding?

at less than 48 hours of age (before feeding)

10

How long to you apply a cautery/hot iron to calves, male goats, and female goats?

calves: 5-7 seconds male goats: 5 seconds female goat: 3 seconds

11

What is a potential complication of using a Barnes dehorner?

you can expose the sinus, causing sinusitis

12

What dehorner is used in older cattle?

keystone dehorner

13

What complications are associated with the keystone dehorner?

sinusitis, surgical site infection, hemorrhage, and improperly performed procedures

14

What is the most common neoplasia of the bovine eye?

squamous cell carcinoma

15

Aside from neoplasia, what are some indications for enucleation?

infectious bovine keratoconjunctivitis, panophthalmitis, and trauma

16

Where can you apply lidocaine for enucleation blocks?

retrobulbar and four point

17

What are the potential complications of enucleation?

hemorrhage, infection, dehiscence, recurrence of disease, and convulsions if you inject lidocaine into the meningeal reflection optic nerve

18

What are some indications for digit amputation?

injury, septic arthritis to the distal interphalangeal joint, severe foot rot and secondary osteomyelitis, and severe phalangeal fractures

19

When should you not amputate a digit?

sepsis of the fetlock joint or involvement of both digits on the same foot

20

While there is a rapid recovery and it is fairly cheap to amputate a digit, what are potential disadvantages to digit amputation?

early removal from herd because of early breakdown and lower market value

21

What antibiotics can you give to prevent infection after digit amputation?

Ampicillin-sulbactam, ampicillin, florfenicol

22

What do we use to make an angled cut for ampuation of a claw?

Obstetric wire between proximal and distal interphalangeal ligament

23

What can help an umbilical hernia heal post-surgery?

a hernia belt

24

26

What instrument does minimally invasive surgery usually utilize?

a camera

27

Not sure why this is important... but who used a cytoscope to examine the abdominal cavity of dogs?

George Kelling

28

Why do we choose to do minimally invasive surgery?

less blood loss, less scarring, shorter hospital stays, decreased pain, and earlier resumptions of new activities

29

What are some cons to minimally invasive surgeries?

operations are longer, may cost more, need extra training, may not see all of the lesions, higher mortality

30

Identify some of the applications for minimally invasive surgery.

laparoscopy, arthroscopy, endoscopy, cytoscopy, hysteroscopy, biopsies, orthopedics
