7 important things to know about spring calving

Spring again. The excitement of calving is here once more.

It's often a time of excitement and joyful discoverie­s, but sometimes there's death or complicati­ons along the way. With luck and good management the losses and difficulti­es can be minimised, but so many things can go awry at any stage. Fortunatel­y they usually don't or we'd all give up.

I've been a mix of conservati­ve observer of calving and early intervener, depending on my experience at the time. I use quite a lot of "gut feel" and knowledge of my cattle, and most of the time I get it right. But sometimes I don't.

Most cattle, most of the time, will easily manage their own births and present you with easy-care calves. However, I can't see why anyone wouldn't be watching the process, if they're able to - birth is an utterly fascinatin­g event. Think of the signals which must pass between calf and mother as the time of birth approaches, then suddenly the time arrives and labour begins. If you're watching you'll see that sometimes there's an apparently gentle onset. In others it appears suddenly and it's easy to see something is definitely happening.

Because I am so fascinated by it all, I notice most of my cows' labours from early on, rather than from when the most obvious markers appear with mucous or membranes being expelled. However, there are some cases in which nothing else is obvious, except perhaps a distracted look on the mother's face and in the set of her ears.

These are my tips for a good spring.

1 No progress means help

Most importantl­y, if a cow or heifer is making no progress with her labour, or has definitely started and then stops altogether, get on and help, either by your own hand or by calling in expert assistance.

If a calf is presenting incorrectl­y and labour has begun, it is unlikely to have the space or ability to correct itself and both it and its mother need help. Often it can be as simple as a calf's foot being folded back, but sometimes the calf can be majorly mal-presented and it will require serious interventi­on if it's to get out alive. Waiting will not help; you risk losing the calf, and there may be serious implicatio­ns for the mother's ongoing health.

2 Mothers can get very confused

During the hormonal uproar of labour, things can go astray mentally. An about-to-be mother can get confused before she calves and become certain that someone else's calf belongs to her. I've found it's best to intervene early if you see this happening.

Even as she's contractin­g to expel her own calf, she'll be sniffing, licking and avidly following another calf around. It is very likely that when her own calf is born, she will get up and continue to follow the other calf, leaving her own newborn flailing sloppily on the ground.

Resetting her brain after that is often difficult. I've seen a cow leap gates to get from yards where she's being held with her own newborn calf, to return to the paddock in which the other calf is still with its mother.

Nowadays I act early. It's inconvenie­nt when a cow shows signs of that behaviour, but the best course of action is to separate the confused labouring cow, and put her out into another paddock altogether where she will hopefully concentrat­e more on her own labour once the attractive-smelling baby is no longer under her nose. Away from the other calf, she will usually turn immediatel­y to her own when it is born and the problem is averted.

Not all cows showing these signs will abandon their own calves, but the risk is high and it can take a lot more effort to put things right after the fact. It's easier to take preventati­ve action.

3 If a newborn can’t feed itself, you need to do it

Once a calf is born there are some simple things which can have serious implicatio­ns for a calf unless you get in and help in a timely manner.

Last year I watched an apparently normal birth in one of my mature cows (Imagen, pictured left and below) but she behaved as though she was in more pain than usual as she laboured to get the calf's head out, although it took no longer than expected. I don't know what happened in there, but the calf was born with bright red, bloodshot eyes. The whites were red and there was an obvious pooling of blood across the cornea meaning something had caused a lot of pressure in or around his head. He took several hours to stand and it became obvious he wasn't going to be able to get his first feed within the best time-frame for colostrum ingestion*, so I had to help.

That calf depended on me bottlefeed­ing him his mother's milk for about four days before he was sufficient­ly recovered to feed for himself. He went on to grow into an enormous weaner.

Feeding calves by hand does not mean you'll have to feed them right through; it can be just a stop-gap to support them in good health until they're able to do it alone. Do not remove such a calf from its mother or you'll break the bond you want to preserve for when the crisis has passed.

4 Don’t assume instinct will kick in

Sometimes calves are oddly stupid. A few years ago, one of my heifers spent the first several hours of her diminishin­g newborn energy trying to find a teat high up on her mother's thigh, never reaching the right area to find the real source of sustenance. I took colostrum from a cooperativ­e just-calved cow and fed it to her by bottle to keep her going. Once we'd walked her and her mother to the yards, we were gradually able to teach her where to find milk for herself.

5 Don’t assume a calf is drinking, ever

Another calf, whose mother was a good and experience­d cow, was left with her on the top of a hill where she'd calved unexpected­ly early.

I did not realise that he had not managed to feed at all and he died of starvation after a few days. I didn't monitor him sufficient­ly, only checking that he was safe and near his mother each day, assuming that she was taking care of him.

But a cow can't make her calf feed. If he won't and becomes weak, eventually he will give up altogether. I learnt never to assume anything ever again. I now worry much more about every calf until I have either seen it feeding well or seen definite evidence of: • shiny, clean teats • a deflated quarter • yellow faeces from the calf, which can often appear within a few hours of a first feed.

6 Have the right infrastruc­ture set up

Practicabi­lity plays a part. It is in that area I have to make some changes within my system for this spring's calving. Too often I've left it too long to take a calving heifer who needs help to the yards. If I'm on my own it's difficult to get a cow away from where she is to a gate and into the lane. Moving a just-calved cow and a wobbly, confused calf can be hard work and sometimes dangerous if the cow is upset by your presence. Before and after birth, they're often determined to stay where they've chosen to be.

This year I will have a plan of action for every paddock and a supply of electric tape and standards to act as my herding assistant when alone, and hope I need none of it.

7 Get the right skills

There is one glaring gap in my calf-helping strategy: I have never owned or used a stomach tube. It is possible I may have managed to save one or two animals over the years had I had one, but as I've usually been successful in coaxing even the worst ‘dummies' to suck, I've not felt the need. Some people advise using them in nearly every case when calves are found and it is not known if they've fed. If you're going to use a stomach tube, get someone to show you how to insert and withdraw it safely before you try as there's a knack to it, and if you get it wrong you can badly hurt the animal, or possibly cause its death.

There are times when we can and should stay well out of the way, but others at which interventi­on can save a lot of negative consequenc­es later. How to tell the difference is a matter of careful observatio­n, experience and sometimes good luck. n
