follicular wave of camelid

successive follicular waves with long receptivity period and short non-receptive periods

follicular phase repeats until ovulation occurs and continue during luteal phase

1

stimuli that cause a camelid to ovulate

- penile cervical penetration
- treading and clasping of male's legs on female's back
- guttural humming sounds (orgling)
- substance within seminal plasma (OIF = ovulation inducing factor)

2

how do you synchronize follicular growth?

altrenogest (regu-mate) - 2.2mg/45kg daily
prostaglandins - 2 injections 10 days apart

3

**what do you give to assist with ovulation: GnRH or hCG?**

**according to Brittany - GnRH**

4

** how large should a follicle be in order to breed?**

**greater than 7mm and growing**

5

when to inseminate?

before ovulation: 22 - 24 hours after induction of ovulation
after ovulation: within 2 hours after ovulation detection

6

** what horn does pregnancy tend to occur on?**

*** the left - 98% of the time! ***

7

gestation length?
CL dependent until when?
placenta type?

gestation length = 335 - 360 days
CL dependent: to term. progesterone dependent to term
placenta type: epitheliochorial, diffuse, microcotyledonary, non-deciduate. amnion adhered to chorioallantois

8

indirect pregnancy diagnosis

behavioral refusal

progesterone assay (P4 > or = to 1ng/ml at 21 days after breeding)

9

direct pregnancy diagnosis

rectal palpation > or = 35 days after breeding/ovulation

ultrasound
transrectal: early as 12 - 16 days
transabdominal; 60 - 90 days = left side; > 90 days = right side

10

termination of pregnancy

prostaglandins - IM
cloprosternol
dinoprost
don't use higher doses - may be life threatening

11

female developmental abnormalities

segmental aplasia
double cervix
double uterus - didelphia
persistent hymen

12

ovarian abnormalities

hypoplasia
cystic follicles
hemorrhagic follicles
neoplasia

13

uterine abnormalities

bacterial endometritis
metritis
uterine scarring (fibrosis)
cystic glandular distension

14

what are some commonly isolated organisms from uterine culture?

strept, e.coli, staph, bacillus, bacteroides, fusobacterium necrophorum

15

what are some testicular abnormalities in camelids?

hypoplasia, degeneration, cryptorchidism, orchitis, hydrocele, neoplasia

16

penile abnormalities?

preputial stricture, persistent frenulum, corkscrew penis, penile deviation, balantis, posthitis

17

**what male accessory sex glands are in the camelid? **

prostate, bulbourethral gland, ampullae

** no vesicular gland!! **

18

***should you use steroids in camelids to hasten fetal maturation?***

NO!
** steroids cause fetal death in camelids **

19

what is the most common cause of dystocia?

lateral flexion of the head

20

when to intervene in a dystocia?

stage 1 > 6 hours - no vaginal discharge or straining seen
stage 2 > 2 hours
