Vaginal Prolapse
Management problem
Over feeding roughage
Large bales
Obese ewes
Short tail docking
Respiratory
Causes of Death
 Starvation
Poor
ewe condition
Weak ewe or lamb
Plugged teats
Mastitis
Mis-mothering
Poor suckling
Stillbirths/dystocia

Symptoms of dystocia
 yellow
fleece
 causes - Fat ewes, Poor hybrid vigor, large
BW

Was it truly born dead?

Stillborns
 -infectious
 -hypoxia
(observation)
Solutions
Condition score
 Observation

 Intercom,
video camera
Feed antibiotics
 Vaccinate against campylobacter
and chlamydia
 BoSe ??????
 Assist after 30 minutes in labor
 Selection

Pneumonia

Causes
poor air quality
too many sheep
wet bedding
Solution
20 ft.2 for ewes with lambs
 Sulfa water treatment
 Improve ventilation

 Open
up barn
Use more bedding
 Pre-lambing shearing

Antibiotics Feeding
60-65 mg/day
 6 weeks prior to lambing
 Results

65-73%  in lamb losses

Intestinal Disorders - Causes
Wet bedding
 Stress
 Inadequate colostrum

Newborn Management
1 - Colostrum intake
 minimum
2 ounces/8 pounds
 ideal 10% of BW first 24 hrs.
2 - Clip - Dip - Strip
 castrate and dock early
3 - Lambing Jugs
4
x 6, 5 x 5
 S 24 hr, Tw 48 hr, Tr 72 hr
4 - Observe often
5 - Check for inverted eyelids
Mastitis Management

Early weaning
 60
days or less
 Dry up ewes prior to weaning
 Reduce
protein
 Reduce energy
 Remove
