Basic Lambing
Length of labor
Signs of labor
Jugs/bonding pens
not lambing pens
High stress high reward
Lambing patterns
Feeding times and lambing
activity
Sleep
timely breeding
Facilities
Bonding pens
4X6 or 5X5
Barn space
15-20 square feet
Causes of Death
Starvation
Poor ewe condition
Weak ewe or lamb
Plugged teats
Mastitis
Mis-mothering
Poor suckling
Prevention: Weak or Starved
Adequate ewe nutrition (i.e. good condition)
Energy level of diet
Crossbreeding
Exercise
Weaning management
Prevention: Weak or Starved cont.
Pre-lambing shearing
Observation
Condition score
Dryer environment
Lamb indoors
Easier nursing
Intake
Solution - Observation
Paint brand
Cubicles & lambing jugs
Shear pre-lambing
Stomach tube
Proper feeding at lambing & weaning
Selenium &Vitamin E status
Trouble Shooting-Use the Thermometer
Normal temp. - 101° - 102°F
Elevated temp.-above 103°F
(think infection)
Cold Lambs
- mild hypothermia 99°-102°F
- severe hypothermia below 99°F
Mild Hypothermia 99°-102°F
1) Remove and dry
2) Supplement warm dry heat
(100°-103°F max. temp.)
3) Tube feed 120-200 ml colostrum
(20 ml/lb.)
4) Return when rectal temperature is normal (1-3 hours)
5) Assure future nutrition
Elevated Temperature-above 103°F
- or animals showing clinical signs
- assume infectious process
- probably pneumonia, joint ill or liver abscess
treat as per VCP relationship-health protocol
- Insure nutrition and hydration
Severe Hypothermia-below 99°F
Under 6 hours old
remove and dry
supplement heat
warm dry moving air 100-103°F
tube feed 120-200 ml colostrum
return when temperature normal
1-3 hours
insure future nutrition
Severe Hypothermia-below 99°F
Over 6 hours old
remove and dry
supplement heat with warm dry moving air
tube feed 120-200 ml colostrum
precaution
inject 50 ml of 20% dextrose into body cavity
1 inch beside and 1 inch behind navel
w/ 20 ga 1/2 inch needle
return when temperature normal
1-3 hours
insure future nutrition
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% ß in lamb losses
University of Wyoming
S.D. State University
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 water ?
