Reading the post about the cow going down with MF and wishing the vet had come sooner, I thought this video might be helpful. We only have one vet in our area and he is always busy. We are very lucky if we can get him out when needed so we've decided to be prepared to make do without him when we have to. We had a case of ketosis over the holiday weekend and had the supplies to do the iv ourselves and were successful thanks to this video. Now, I keep the medicine chest complete with the calcium iv and dextrose iv along with a new iv set. I also keep the B shots and many other things which have proved to be very helpful. When you need it, you need it right away. Anyway, hope this helps someone.

I have the second link (the farm girl one) listed on my website. (http://spiritedrose.wordpress.com/jersey-cattle/medicine-box/how-to-give-an-iv-for-milk-fever/) It's not exactly how we do it, but realistically, if you find your cow with milk fever, she's not going to be in condition to walk into a stall for you!!
Some great info there! I was also wondering if administering via tail vein would be an option, i know id feel more confident from that end, so I did some research and from what I can gather it said tail vein is great for blood collection, but as the vein is small an iv would be very slow running through the tail vein, imagine holding the tail up:) I haven't had to treat for MF so don't have any experience, but it seems that the calcium iv has to be run slowly so tail vein maybe another option? Maybe someone with experience will chime in:)
Hi Rosalind, how long typically does it take for the calcium to run through & do you give just straight calcium or? I didn't know about having solution at the withers, when I read it has to run slowly I was thinking of a smaller gauge needle, what size needle do you normally use? No I won't try tail vein not after reading up about it:)
I've never actually timed it.... but I would think somewhere between 5-10 minutes? We go more by the air bubbles that come up thru the tube into the bottle. If it's really fast bubbles, then it's too fast for calcium. If it's slow bubbles, then it's okay.
"straight calcium" is still diluted in Dextrose. There's also CMPK (calcium/magnesium/phosphorus/potassium) that is very effective, because often cows are imbalanced in more than just calcium and they all function together. Then, there's also "striaght" Dextrose and saline. Saline would be for a cow that's sick and not drinking, it's a way to get her thirsty. Dextrose is a general "pick-me-up" for a cow that's sick and not eating well, it gives her time/energy to heal.
We use a 14 gauge needle. Most people probably use 16. My husband's been doing IV's his whole life, so he's practiced in doing it. Plus, the larger needle is more stable as far as staying in the vein. Like I said earlier, we adjust the speed by how high up we hold the bottle, just a gravity trick.
Just watched my vet do all of this for Dottie; she was down with MF this morning. It really isn't as hard as it looks. But then I'm a nurse and do IV's all the time on people, so I'm less intimidated by the idea.
A couple of things the vet told me today that I found helpful:
1.) She gives IV calcium until she either feels the heart rate slow (she feels the pulse while she's holding the IV in the vein) or until the cow starts to shiver. If either of those signs occurs, she stops the IV calcium.
2.) As much as it can be risky to give IV calcium, she's never seen that alone actually kill a cow. She's actually seen vets try to give it fast to euthanize a cow when there was no other option, and it never worked. In her experience, if a cow dies during an IV calcium infusion there was probably something else contributing. So I'm less nervous about giving it myself now if I have to.

Thanks for that info Joelle, I'm hoping I will never have to deal with MF (wishful thinking) and won't need to site & administer the iv, I'm a phlebotomist so the actual iv won't be a problem, it was the speed & thought that I could possibly kill my girl that had me worried, after reading what u have posted puts me a bit more at easy, if & when the time comes:)

Couldn't hear the video because sound on my computer isn't working grr... lol but a lot of people have difficulty finding the vein in the neck. Although if your patient you can see it pop like in the video. So for those people that need to do an IV without a vet around and cannot find the vein in the neck I would reccomend putting it in the milk vein. The big fat vein you can see running from the cows udder up her belly (if your not sure the one google search milk vein) this one is very simple because you can already see the vein so all you have to do is jab the needle into it and blood will start pouring out. Use a new needle so its nice and sharp. If their really sick they wont kick. If they have some spunk to them still get a person to tail jack the cow (lift the tail straight up) This method works just as well as the vein in the neck, but if you miss it, or go through it you can cause it to get an alcer. so just be gentle when doing it. Also once your finished giving the drug hold the area off for a few seconds with your finger because this spot really bleeds.
Also if administering calcium be very careful giving it in the neck vein. if you aren't monitoring their heart pinch the IV hose off every 4 to 5 seconds with your fingers. If it is given too fast your cow can drop dead or so my vets told me. Dextrose, and drugs for mastitis that need to be IV'd can go in fast.

Regarding giving IV fluids (of any sort) in the milk vein: I've done it hundreds of times. There are a couple caveats, however. First, only do it with mature cows where the milk vein is truly really obvious, never first calf heifers as their milk vein isnot prominent. Why? If you miss the milk vein and create an abscess, you'll regret you ever gave it there as the area will swell terribly for a good couple weeks. They'll be off-feed and in pain. Like someone said, maybe have someone tail jack the cow, that's good. Also slap the vein firmly 4-5 times before jagging the needle in. I always point it towards the udder, but it doesnt really matter. When you're giving the fluids, make sure you place the IV line against her side with the back of your hand that's not holding the bottle, so the line isn't just dangling otherwise they may kick as it might feel like a fly. More importantly is that if they start to kick, the needle may have gotten misplaced somehow and the fluid is going next to the vein, not in the vein. How do you tell if you are in the vein (milk vein or jugular vein)? By lowering the bottle lower than the needle. Blood should immediately start coming back into the line. If so, great, raise the bottle up again and keep running it in. If blood is not seen right away, then you could well be outside the vein and you need to re-stick her. Don't ignore kicking at the site when you are runnin gin fluids into the milk vein. By the way, you can hold any kind of fluid as high as you want. You will feel like the statue of liberty after a while. But do NOT run in calcium products fast - my safe method is to hold them no higher then the backbone at the shoulder blades. Haven't killed a straight up milk fever yet in having done hundreds. Also, hitting the milk vein in a standing cow is very handy compared to tying up their head, which by the way I always have the nose near the ground and turned to the right side to do a jugular vein in a standing cow. Like I said, I've done countless IVs in the milk vein of standing cows - just NOT first calf heifers or real "witches" as they can kick the living crap out of you when you first jag them with the needle. I use 14 gauge 2 inch needles for cow IV, whether in the milk vein or jugular. When a cow is down with milk fever it is always better to give in the jugular so you can check if you're in the vein by lower the bottle lower than the needle, which you can't do with a milk vein in a lying down cow.

My Jersey Violet got milk fever again. She calved last Thursday, came down with milk fever on Friday. Called a vet he recommended the calcium gel. We gave her some, and some of you kindly posted to give her calcium sub Q. Luckily she seemed to be doing fine, put the calf back on her, two days later, and today she went down again. Luckily for me my son and son-in-law were able to get some calcium and an IV kit and with some coaching over the phone by my father,(an old hand at it) they were able to get the calcium in her and she is now standing on her own, (Thank goodness). I didn't know a cow could come down with milk fever twice. The vet recommends that we take her calf off of her for a week. Does anyone know how long before I dare try milking her? She sure has had me worried.
I have a cow that is about to calf that has had milk fever with her previous owner. I have oral calcium and the calcium IV. The reading I had done said subQ was good enough because the risk involved in the vein. Has anyone had success with the subQ?
