Calving Signs Cow or heifer becomes restless Loss of appetite Discharge Bag up – udder fills with milk
(colostrum)
Difficulties with Calving
Dystocia difficult birth, typically caused by a
large or awkwardly positioned fetus, by smallness of the maternal pelvis, or by failure of the uterus and cervix to contract and expand normally.

Correct Positioning of Calf
• Feet First• Then Nose• Within 30 – 45 minutes calf
should be on the ground
Problems with the calf
A-F • All of these positions can
present potential problems with the parturition process.

Twins The worst of the situations with twins is when each calf presents itself in the birth canal.

Problems with Mom
Torsion• The twisting of the uterus,
therefore not allowing the calf to pass.
• The solution is untwisting the uterus. Which requires a phone call to your local large animal vet.
Time to get the calf out.
Step 1: get the chains properly positioned around front legs.
Step 2: Offset the shoulders and pull
Discussion Activity:
- As soon as you have the chains on, do you just yank the calf out?
- Discuss with those around you what you might think the next step would be upon placing the pull chains on the calf.
