1

If this nerve is damaged, the animal will not have a normal

ejaculatory response

Dorsal nerve

2

This artery supplies the corpus cavernosum of the penis

Deep artery of the penis

3

Muscular contraction of these 2 muscles,

and increased blood supply to the corpus cavernosum via the deep artery of the penis

result in erection

Bulbospongiosus

Ischiocavernosus

4

For penile examination in the bull,

what 2 meds can be used for sedation?

Xylazine

Acepromazine

5

This nerve block

blocks the supply to the retractor penis muscle

allowing for examination of the penis

Pudendal nerve block

6

What is the easiest way to exam the bull's

reproductive system?

View a mating attempt

7

At what age should castration be performed

in bulls?

1 - 3 months old

8

What are the main points supporting the argument

for older castration in bulls?

Claim better growth WITHOUT implants

Claim that Callicrate banders

are the most humane way to castrate an animal

9

What 4 pieces of equipment can be used to

castrate a bull?

Newberry Knife

Elastrator

Callicrate

Burdizzo

10

What is this tool used in the castration of ruminants?

Newberry Knife

11

Name the castrating tool described by the following:

Firm band that stretches over neck of scrotum (testes distal)

and constricts until avascular necrosis of scrotum.

More commonly used in rams than in bulls.

Elastrator

12

What is this tool used in castration?

Elastrator

13

What is the biggest risk of using an Elastrator?

Leaves a large piece of avascular tissue

=

Risk of TETANUS

14

Name the castrating tool described by the following:

Tool used in older bulls for castration.

Pulls and clamps so tight, goes past the point of discomfort.

Callicrate

15

Name this castration tool

Callicrate

16

Name the castrating tool described by the following:

Clamps and crushes the ductus deferens and

vascular supply.

Must remember to stagger the clamp on opposite sides

or will have necrosis of whole scrotum

Burdizzo

17

What is this castration tool?

Burdizzo

18

Describe the cause and etiology of 

ulcers of the preputial orifice

hair clipped too short

urine accumulates

urease-producing organisms produce ammonia

Ulceration, secondary infection

19

This type of ulcer occurs in 

overweight rams that are confined and lay down a lot.

The ulcer forms from laying the prepuce against the ventral

abdomen- basically a bedsore.

It is seen dorsal to the preputial orifice.

Decubital ulcer

20

How are decubital ulcers treated?

SURGICAL EXCISION!

 

Cannot be treated conservatively!

21

Preputial prolapse is mostly seen in this type of cattle

due to their long, pendulous prepuces.

Bos Indicus

22

T/F:

Preputial prolapse is seen more commonly in dairy breeds

FALSE

Beef breeds- Angus

23

How is preputial prolapse treated?

Hold it against the body with a bandage

+

Exercise and hydrotherapy

24

Inability to EXTEND the penis is known as

Phimosis

25

Inability to RETRACT the penis is known as

Paraphimosis

26

A ring of inelastic tissue near the tip of the prepuce

that prevents retraction of the penis

Cicatrix

27

How is stenosis of the penis

(phimosis, paraphimosis)

treated?

SURGERY

Make longitudinal incision

and suture transversely.

NOT a circumferential incision- risk of cicatrix

28

Preputial avulsion/ penile laceration

is only seen in __________ bulls,

typically after return from a lay-off period

AI (artificial insemination bulls)

29

Preputial avulsion/ penile laceration

is treated via prompt _______

surgery- suture tear together

30

What is going on here?

Persistent Frenulum
