Watch a calf being born

Although we keep an eagle eye over cows as they approach calving time, most give birth perfectly naturally without any help from us just like this lovely lady. Her calf was up and walking within the hour and running by the afternoon. These little animals are amazing sprinters! Just ask eight-year-old Zoe, who tried and failed miserably to outrun a three-day-old calf this morning!

Stealing the calf’s milk

There’s an urban myth that dairy farmers rear calves away from the herd so we can harvest the special buttercup-yellow milk that comes with the first milkings after calving called colostrum. The irony is that one of the main reasons we collect calves early is to ensure they get plenty of colostrum.

According to a Dairy Australia fact sheet on colostrum management:

“Unlike humans, the placenta of the cow keeps the maternal blood supply separate from that of the unborn calf. This prevents the transfer of antibodies from the cow to the calf before birth and the calf is born with no ability to fight disease.”

“Colostrum is the substance that provides the antibodies that form the main protection from infectious diseases for the calf in the first 6 weeks of life, until the calf can develop antibodies of its own. Without colostrum, a calf is likely to die.”

What’s more, calves need it immediately, as DA goes on to explain:

“It is important to be clear about two key facts relating to colostrum:
• The calf’s intestine absorbs the large IgG molecules easily straight after birth
• The intestine’s ability to absorb antibodies decreases after birth—it decreases by 30–50 % within 6 hours of birth
• It stops completely between 24 to 36 hours after birth”

Yes, it’s vital to our calves.

We don’t sell a drop of the precious stuff (few farmers do, which is why it’s so expensive) and we’re not allowed to mix it with the rest of the milk because it goes off quickly. “Stealing colostrum from calves” is certainly not why we raise the calves away from the herd.

Beautiful birth

By the time I took this photo at 11.50 yesterday, I’d been watching over cow 506 for an hour or so. She’d been showing all the classic signs of a cow about to calve: restlessness, getting up and down. It was a relief to see her labour had progressed. I came back again an hour later to make sure everything was okay and look what I found! Licking her little one with gusto, she looked very comfortable.

Of course, it’s not always this simple. Sometimes the calf is too big, sometimes breech, sometimes the cow herself has a problem. With 340 cows set to calve over the next few months, it’s an anxious time for us.

To make it easier to keep an eye on our ladies, we do a weekly sort-out, drafting cows that are about three weeks from calving out from the rest so they can get extra special TLC in our calving paddock. This paddock is small and close to the house and dairy. We check it three times a day and, if any of the cows look like they’re about to calve, we hop up during the night to check them as well. Some of the signs are a swollen vulva, mucus, tight udder and unusual behaviour. The reality is though that, despite breeding programs meddling with the cow’s biology for thousands of years, almost all of them calve quite easily.

I hate comparing women with cows but, at almost 36 weeks myself, I can’t help wondering why it seems so much more complicated for us!
