Helpful tips from North Dakota State University Extension Service to help cattle cope with cold weather.
Calf loss and dystocia can be stressful for cattle and their owners. Dystocia is the medical term for a difficult birth. Knowing the stages of labor can be helpful in determining when to call the vet for help. Early recognition of a problem will help you save calves and increase the odds of your cow breeding back. The table at the end of this post provides thumb rules for each stage of labor. Veterinary intervention is suggested if cows exceed the time limits of these thumb rules.
STAGE 1 – PREPARATION
During stage 1 of labor, the calf is rotating into the correct position. The cow may be seen getting up and down and will usually separate herself from the rest of the herd. The cow may seem nervous, uncomfortable, and will likely stop eating and chewing her cud. Once the water sac is expelled, this marks the beginning of stage 2 – delivery.
STAGE 2 – DELIVERY
Once the water sac is expelled, the clock starts. If there is not continual progress, something is likely wrong. A cow should deliver her calf within 30 minutes and heifers may take up to 1 hour. The key is PROGRESS – if the animal is not progressing, call for help.
Signs of trouble:
- If the water sac has been visible for over 1 hour and you have not seen any progression (the cow is not trying).
- If the cow has been trying for over 30 minutes and making no progress.
- If the cow has quit trying for more than a 15-20 minute period. Rest periods normally should not last longer than 5-10 minutes.
- If the cow or calf is showing signs of stress or fatigue — like a swollen tongue in the calf, yellow staining of the calf, or severe bleeding from the cow’s rectum or vagina.
- If you suspect that the calf is not in the normal position.
- If the front feet are crossed and the head is not visible, the calf may be malpositioned or too big to pass through the birth canal.
- A thumb rule is that if the calves knees are not visible at the vulva, there is likely a problem.
- A breeched calf is one that is being delivered tail first. This is an emergency and requires assistance to get the back legs extended and into the birth canal.
If the calf is not in the correct position OR if you do not know if the calf is in the correct position – DO NOT attempt to forcefully extract the calf with a calf-jack or winch – call the veterinarian.
STAGE 3 – “CLEANING”
In most cases, the placenta, or “afterbirth” is delivered immediately after the calf. There are a number of reasons why this may become delayed beyond 8 hours. It is not an urgent emergency in cattle, but the afterbirth will need to come out. There are several methods for handling the situation to prevent infection and decreased fertility. See our post on retained fetal membranes for more information on how this condition is managed.
STAGES OF CALVING SUMMARY
|Stage and time||Events|
(2 to 6 hours)
|1.Calf rotates to upright position.
2.Uterine contractions begin.
3.Water sac expelled
|Stage 2 – “Delivery”
(1 hour or less)
|1.Cow usually lying down.
2.Fetus enters birth canal.
3.Front feet and head protrude first.
4.Calf delivery completed.
|Stage 3 – “Cleaning”
(2 to 8 hours)
|1.caruncle-cotyledon (button) attachments relax.
2.Uterine contractions expel membranes.
Calves should be on their feet and nursing within 4 hours. The cows first milk, or “colostrum”, contains antibodies that will protect the calf until it is old enough for vaccines. These antibodies are most optimally absorbed within the first 12 hours of life, and cannot be absorbed after 24 hours of life. Calves that do not get colostrum during this critical period are susceptible to infections and are unlikely to thrive.

TheCattleSite.com published a wonderful overview of “grass tetany” this month. Low blood levels of magnesium is the cause of grass tetany, or “grass staggers”. This condition is normally seen in early spring, largely due to low magnesium and high potassium in lush green pastures. The condition can cause seizures, nervousness, rigid/tetanic muscles, and even death in cattle. Supplementing cows with a high magnesium mineral 30 days prior to calving is a great preventative as spring approaches. Read the full article for an overview of the condition and give us a call if you suspect this condition in your animals.
