In the herds that we have been utilizing ENDOVAC-Dairy, E. coli mastitis control is not only the control benefit seen, it has also benefited us by utilizing Endovac
in that relationship concerning Salmonella. You know, the less shots you have to give, the better off we are. As for the Milk drop, we’ve proven to ourselves through our own research, we do see less milk drop with Endovac. That gives us flexibility where she is in gestation and lactation and that’s a pretty big deal!

Hi, my name’s Jonathan Hess, DVM. My practice is Hess Veterinary Service West based in Hagerman, Idaho. I serve in the Magic Valley. We focus quite a bit on the efficiency of our young stock replacement operations. I always thought Endovac had a place in the young stock just because the amount of gram-negative exposure. We use ENDOVAC-Dairy in the first week of life. It’s very smooth. No matter how good your husbandry is, you’re still going to have a myriad of gram-negatives and those gram-negatives seem to be getting smarter and stronger. Salmonella is really everywhere. It’s not something you get rid of, it’s something you manage. What I like about Endovac is the management of salmonella and any gram-negative really, which is crazy. It’s really helped clients manage through that diarrhea period which usually shows up around 10 days to two weeks and continues into twenty to thirty days. It seems to work well for us.
As far as other uses, I do have other facilities that struggle with gram negative pneumonia problems after the animal leaves the hutch. There’s been gram-negative vaccines in the past that are a little harder on the cow or the calf, especially ones related to respiratory. Endovac is employed there one to two weeks before they move to a different housing situation to address certain gram-negative pneumonias. You know, the ever-present, I say Pasteurella but there’s other things. There’s quite a bit of Salmonella pneumonia that people don’t even want to talk about, but it’s there. Places that use it younger, boost them if you will, to get them ready to go to the co-mingled housing. It has really helped with slowing down quite a bit of the treatment rates on these places. As far as a consistent product that has a 40-year history, it’s smooth and safe. I definitely feel confident to stick with this for gram-negative control.

ENDOVAC-Beef was first presented to me as an immune stimulant, and we started using it on commingled cattle
coming from multiple high stress environments to our ranch. I saw a higher immune response in these cattle and started using Endovac on all of our cattle at all five locations. We have a 2,000 head cow/calf operation and 500 head of stockers with ranches in south Florida and south Georgia. Whenever calves go through the chute, they receive a shot of Endovac. We currently run between .5% and 1% mortality on our calves with Endovac down from 3% before we implemented Endovac. On the calves that are going to the feedlot, we are getting positive feedback of fewer treatments since starting Endovac. When you are selling on reputation that is important. And on top of all that, with the price, you can’t go wrong.

There’s no way to make money planting them, I’ve yet to see one grow. We background calves, have a history in the cow/calf side, and have a finish feed yard in a GAP4 environment. For the last feeding year period, we handled 5,800 to 6,000 head through here. I just finished doing my audit back in early October and I had 27 treatment records. Endovac was recommended to me by a fellow who feeds and starts quite a number of cattle. He had good luck with it in his system. His system was more high risk than ours. We adopted it into our program because of the immune boost of it. The fact that it makes the vaccines work that we give means we simply just don’t treat cattle. For us, receiving cattle is when we set the tone for the production of our farm. Everything we do from the minute that calf walks off the truck, we will reap the benefit on the other end if we do it properly, or we will be backing up the whole time. Cattle health is extremely important in this process because a treated calf is just costly for us. But if you have a known product, the immune booster, is valid. It is what it is.
We also know that the most important thing to cattle when moving is water. You would see a definite difference if you provide fresh clean water or if you don’t. We do, so we don’t know what life is like without it. Same with the Endovac– we use the immune booster. We can’t necessarily tell you that this exact number of calves responded better than others from it, however, we know it is an important component in what we do just as much as fresh water or fresh clean feed to that calf when it is going through a stressful time. The Immune Plus is a huge benefit, and we see it from there on throughout the feeding period of that calf remaining healthy, never coming off feed, doesn’t have to be treated, doesn’t fall out of our market share, or simply just never falls behind on a sick day or feeling off. We set the cattle up the best we know how from day one to perform. We can attribute that to Endovac and the process that we use in trying to cover all those bases. 100%… the responsibility where Endovac is in our system, it works, and it helps the other vaccines we use work better. It’s a no brainer for us!

We have used ENDOVAC-Dairy for over 20 years. ENDOVAC-Dairy gives us the best E. coli Mastitis protection and assists us in keeping our 600 cow freestall operation under 125,000 SCC. We do not see a milk production loss while using ENDOVAC-Dairy and the Immune Plus component of the vaccine helps keep our herd healthy and strong. All our calves are fed colostrum from ENDOVAC-Dairy vaccinated cows, which allows them to stay ahead of E. coli and Salmonella scours.
