(Dan) Hey folks, welcome to DocTalk, excited about the show today. We’re going to have Dr. Dave Rethorst with us and we’re going to talk about some of the things that you’re going to do at that spring turnout or turnout processing of calves, cows and your pre-breeding shots for the bulls and the cows. Thanks for joining the show. More after these messages.

(Dan) Hey folks, welcome to DocTalk. Dr. Dave… (Dave) Good to be here Dan, as always. (Dan) Folks, this is my friend and colleague Dr. Dave Rethorst and Dr. Dave is the Outreach Veterinarian for the Veterinary Diagnostic Laboratory here at Kansas State University and he’s one of those people that we call on for expertise in the beef cattle area, all things cows and calves and bulls is Dr. Dave’s subject expertise. Thirty some years… (Dave) Thirty—–eight years since I graduated. (Dan) That’s cool. So, a lot of experience, is the way we like to phrase it. And Dr. Dave when we talk about cows and calves, we’re going to talk about turnout processing and branding programs folks. But Dr. Dave we’ve got some checklists. Let’s go through the annual checklist. We’ve got calves, we’ve got cows, we’ve got bulls. The thing that producers are going to be thinking about, first of the year, springtime, fall. (Dave) OK. (Dan) What are we working on? (Dave) OK. Right now we’re getting all these cows calved out, so here in a couple of months we’ll do that turnout processing. We need to think about what vaccines we’re going to use preparatory for weaning. We’ll come back, we’ll do some other things preparing for weaning. This fall, we’ll get those calves ready to go to the feedyard. (Dan) So those calves, we’re going to calve them out first of the year, come back two to four months, that spring processing turnout. Then they’re going to go out on the pasture with Mama. (Dave) Yep. Absolutely. (Dan) They’re going to be out there til they’re seven months old, come back and we’re going to wean them. (Dave) Then we’re going to wean them. (Dan) Now, what about the cows? (Dave) Cows, again, we’ll do some of the vaccinations when we get done calving preparatory for breeding season. Come back when those calves are weaned, we’ll preg check those cows, find out which ones get to be Mamas again next year and then go on, those that are pregnant then we’ll come back and process them again many times right before they calve. (Dan) And you’ll do that just like a pre-calving, kind of that colostrum boost to get a better pass of immunity to that calf. (Dave) Right, right. (Dan) OK. And then the old bulls? (Dave) Señor bull. (Dan ) That’s right. (Dave) This time of the year, they’re just out there eating. It’s time to start thinking about getting them ready. We’ll do our breeding soundness exams, many of those going on right now, some vaccinations, get those bulls ready to go out and do their job for 60 to 90 days. (Dan) So, when we’re doing spring turnout, that’s when we’re going to start doing our breeding soundness exams, making sure that the bulls are fertile and available for breeding, turn them out, body condition score usually around a six? (Dave) Five and half to six. (Dan) When we turn those bulls out, and that’s it. So, calves, cows, bulls and obviously you want to vaccinate your bulls for your venereal diseases and things to that nature, the pre-breeding vaccinations when we semen test. When we come back from break, Dr. Dave and I are going to jump on this branding or turnout processing for these baby calves. We’re going to talk about cattle handling, preparing them. Thanks for watching. More after this break.
(Dan) Hey folks, welcome back to DocTalk. Dr. Dan Thomson here with Dr. Dave Rethorst. We are here at Kansas State University’s College of Veterinary Medicine where Dr. Rethorst serves as the Outreach Veterinarian for the Veterinary Diagnostic Laboratory. Thirty-eight years of cow/calf and feedlot production medicine and individual animal medicine practice experience and someone who just has a true passion for the beef industry, the veterinary profession and things that we do. We’re going to talk Dr. Dave, about vaccines first. Let’s jump on what do we, and folks remember this, always work with your local veterinarian. (Dave) Absolutely. (Dan) Dr. Dave and I are going to give you some general core vaccine strategies. There will be others out there that your veterinarian knows your cows, knows the geography, knows the epidemiological survey of your area, but we’ll just visit. (Dave) We’ll just visit, give our preferences. (Dan) That’s right. (Dave) Then they can discuss it with their veterinarian. (Dan) Don’t get us hung up now. So, let’s talk about vaccines. What kind of vaccines are you looking to give these baby calves at branding? (Dave) I start off, the viral vaccination is as important, if not more important to me, than the Black Leg. And the Black Leg is pretty important. But we want to give that Black Leg… (Dan) So walk me through the antigens in that viral vaccine. (Dave) OK. We can go simple or we can complex. The basics that I really want to see is an IBR and a BVD. Now, we can add BRSV and we can add PI3 to that and in most cases those are added and by the time you throw the second strain of BVD in there that’s where we get our 5-way modified live vaccine. (Dan) And you are using modified lives on these baby calves? (Dave) Yes. I do recommend modified lives on these baby calves. It does a better job of priming that immune system getting ready for fall. (Dan) And I do too. We’re going to look at that 5-way modified live viral and then Black Leg. (Dave) And then Black Leg. (Dan) Now some of these people, this might be the second Black Leg vaccine? (Dave) It could be the second Black Leg. There are some people that give a Black Leg at birth when they tag that calf trying to shut down some of those enterotoxemia, these absomasal ulcer type things. (Dan) And if you have a pasture that is, there are Black Leg pastures and non-Black Leg pastures. (Dave) Absolutely. (Dan) And so if you have had cases of Black Leg, we really recommend that you get that vaccine in those calves at birth, follow up at branding. Other vaccines? (Dave) An awful lot of Pink Eye vaccine used on these spring turnouts. People use it. I sometimes question whether it’s worth the dollars we spend on it. I think we ought to spend that buck and a half a head on fly control and we’d be better off. But each to their own. (Dan) So when we come back from the break, we can jump into some of that fly control and fly tags and things to that nature. But the three big vaccines we’re going to do, 5-way modified live viral, a Black Leg and potentially a Pink Eye. (Dave) Absolutely. (Dan) Great. When we come back, we’re going to talk a little bit more. We’re going to talk about castration. We’re going to talk about steroid implants. You’re watching DocTalk. Dr. Dan. Dr. Dave. Kansas State University. More after these messages.
(Dan) Hey folks, welcome back to DocTalk. Dr. Dan Thomson here with Dr. Dave Rethorst. He is the Outreach Veterinarian for the Kansas State University’s College of Veterinary Medicine, Veterinary Diagnostic Laboratory, 38 years of bovine practice experience and just a wealth of knowledge. Lucky to have him as a colleague and a friend. One thing is I want to make an announcement that we’re going to start doing here on the show and you can see here on the set, we’re going to build some shelves folks. And what we’re going to do on these shelves is if you will send in or mail in your ranch cap, we’re going to start highlighting different ranches and the caps along the back of the set in the studio here. Just something that we want to do to help recognize you folks that are out there watching the show and you know now, keep it clean. It can have manure on it. But I just meant on the verbiage on the cap. Alright? So we all have some creative names, and so anyway, it will be fun and we’ll get you some information to mail those in, or email us and we’ll shoot you out the address. But it will be a lot of fun. Now, Dr. Dave we’ve vaccinated the calves. What are we going to vaccinate the cows and the bulls with? (Dave) Again, we’ve got to reduce that viral pool in the cow herd if we’re going to cut down respiratory disease in the calves and cut down antibiotic use. It’s kind of a big vicious circle Dan. So, I like to use, particularly in the younger cows, a modified live 5-way viral on these cows pre-breeding. (Dan) OK. (Dave) We’ve got again after that IBR, we’re after both strains of BVD on that. We also need our Vibrio vaccine and our 5-way Lepto vaccine. (Dan) So, 5-way modified live IBR, BVD Type One-Type Two, BRSV, PI3 followed up with the Lepto, Vibrio vaccination. (Dave) Yes sir. (Dan) Any other vaccines for those cows at this time? Again, maybe the Pink Eye, but the jury is still out? (Dave) Yes, the jury is still out on the Pink Eye vaccine. We’ve had an awful lot of Trich in the state of Kansas in the last few years. Not quite so much last year compared to ’13. It’s still out there. There are some people using that vaccine. Jury is still kind of out on that one too. It will improve pregnancy rates a little bit, but it really doesn’t get it out of your herd. (Dan) Same vaccines for the bulls? (Dave) Yes, except the Trich vaccine. The Trich vaccine is not approved. Work hasn’t been done on Trich vaccine in bulls. But the IBR, BVD, Vibrio, Lepto on the bulls, maybe Pink Eye. (Dan) And so basically same vaccines-cows, calves, bulls- but the calves will get Black Leg instead of the Lepto, Vibrio. (Dave) Yes. (Dan) Good. Good solid vaccination platform. And then that leaves us folks with what we’re going to finish on those baby calves, and basically it’s just castration, dehorning and disbudding, right? (Dave) Right. (Dan) I mean implants. (Dave) Implanting. (Dan) And deworming-a lot of people will either deworm at branding.. (Dave) Right. (Dan)…or wait until June. (Dave) Some people I’ve worked with over the years will use an injectable in those babies when they’re doing the rest of their processing, some of them will wait and use an oral product through the mineral, through the feed in June. That strategic deworming, trying to keep the pastures clean. (Dan) But what about the cows? Sometimes we’ll clean up those cows, give them a vaccination. (Dan) This is some great information. Let’s take a break. Folks, when we come back we’re going to talk more with Dr. Dave about pre-turnout processing of cows, calves and bulls.
(Dan) Folks, welcome back to DocTalk. Dr. Dan and Dr. Dave, Kansas State University where Dr. Dave is the Veterinary Outreach Veterinarian for the Veterinary Diagnostic Lab. And let’s clear up the deworming real quick. Some people will deworm calves, most don’t at turnout. (Dave) Right. (Dan) Some will deworm cows with an injectable at turnout because we have them caught. (Dave) Right. (Dan) And then the strategic, oral safeguard Fenben dissolve type deworming in the summer. (Dave) Right. (Dan) OK. Now, fly tags. And I know that this is another one of those controversial things, but we’ve got to, the best would be to put them in later in summer, but we’ve got to do it when we’ve got them caught. (Dave) Right. A lot of fly tags go in at the time of this turnout processing. I understand that. It’s better then than not at all. But most of those fly tags have a two to three month window, so if you’re going to handle cows, if you’re changing pastures, going by corrals the first part of July that’s the ideal time to put in fly tags because you’re going to have the most bang for your buck with those tags. (Dan) Gotcha. (Dave) But if that isn’t an option, get them in now. Use the oral larvicides, that sort of thing, but let’s get a handle on flies. (Dan) Alright. Now, we’ve had Dr. Reinhardt on here talking about which steroid implants to use on these steer calves and we’ve covered suckling implants for heifers, if you know they’re going to be breeding heifers, don’t implant them. (Dave) Right. (Dan) If you don’t know if you do it at one to two, during branding, you’ll be OK with a low potency implant. But what about the importance of castrating these calves at the time of branding? (Dave) I think it’s absolutely essential to castrate these calves as babies. It’s less stress on them as babies, than it’s going to be at weaning. We can help cut down on some of our respiratory disease stuff because of that stress. If we look at castrate, put a low potency implant in them, those calves 30 days post weaning are going to be heavier than a bull calf that’s castrated at the time of weaning. (Dan) Oh big time. I think people don’t understand that there’s no advantage to leaving the testicles on for performance prior to puberty. (Dave) Right. (Dan) Until we have puberty, we don’t get testosterone production so there’s no advantage and there’s a huge disadvantage to performance and stress. (Dave) Absolutely. (Dan) As always my friend, great information. Folks, hopefully you’ve got a better appreciation for the annual cowherd flow. Got an appreciation of what we’re going to do at spring turnout and processing for the calves, for the cows, for the bulls. Vaccines, castration, steroid implants, lots of things going on. Remember always work with your local veterinarian. And if you want to know more about what we do here on the show you can find us at www.doctalktv.com. I’m Dr. Dan Thomson. Thanks for watching DocTalk today and I’ll see you down the road.
