Procuring your calf care products just got a little easier as GENEX introduced ReMOOV™ horn paste, an easy-to-use caustic paste that inhibits horn growth. This product contains a mixture of calcium hydroxide and potassium hydroxide in an aqueous glycerine gel. Using the paste over other horn growth inhibiting methods means:
› Less stress to the animal
› No expensive equipment
› No bad smell
This new product has even more great features:
› ReMOOV™ horn paste is packaged in a uniquely designed syringe that measures out the perfect amount of paste needed for each horn button.
› The syringe also has a special tip enabling precise application to the horn bud.
"Not only does the syringe make this product easy to administer but it is also less painful to the animal, less stressful for the animal and you, and there is not bad burning smell like there is with hot irons," states Bob East, senior manager of the GENEX herd care line.
ReMOOV™ horn paste is available in 1.6 oz syringes that can disbud approximately 24 animals. They are packaged at six syringes per box.

Anna Whitt of Spring Hill, Tennessee, was selected as the GENEX Beef intern for the summer of 2018. Based on the opportunities she had, the knowledge she gained and the people she met, she called it the internship of a lifetime. Here she shares her thoughts:
Never would I have imagined the opportunity to travel out west for a summer, much less participate and become more educated on what I truly care about: breeding cattle and all the factors that go with it. However, being the GENEX Beef intern gave me that opportunity and more.
Coming from a smaller, 40-head black Angus herd in Tennessee, I never realized how different things are out west! The fast pace, hard work, dedication and care for cattle that goes into artificial insemination (A.I.) breeding projects is more than I ever imagined. Additionally, knowing synchronization protocols and bull EPDs are major factors that create the desired genetics producers want in their herds.
Throughout the internship, I was often asked, “What’s your favorite place you’ve been so far?” I can honestly say I didn’t have a favorite. I saw mountains, valleys, hills and canyons. I was around all ages, sizes and breeds of cattle. One thing was certain, though: I met so many wonderful people along the way who share a love for cattle.
As the saying goes, “If you love what you do, you’ll never work a day in your life.” This statement couldn’t be any more accurate for the GENEX teams I worked with during my internship. Everyone cared not only about their quality of work, but also the relationships with producers they built along the way
This internship was the experience of a lifetime. I was able to further my knowledge, skills and hands-on experiences in something I am truly passionate about. After helping breed over 4,000 head, traveling over 6,000 miles and visiting eight states, I’d say GENEX has provided this ole homebody Tennessee girl with the perfect start to pursuing her dreams. And, I couldn’t be more thankful or blessed!

Searching and sorting dairy bulls from across the industry just got easier with the release of a new app from GENEX. The Dairy Bull Search app - available for download on Apple, Android and Windows devices - includes genetic and predigree data on over 40,000 bulls.
The app enables your to search for Holstein, Jersey, Brown Swiss, Guernsey, Ayrshire and Milking Shorthorn bulls by entering their short name, NAAB code or registration number.
"The app also allows users to filter active bulls by genetic criteria to generate a list of sires that meets your breeding objectives," explains Joe Binversie, GENEX Value Added Programs Manager. "This list can be downloaded as a Microsoft Excel or CSV file which you can save to your device or send via email or text message. It makes bull searching and sorting quick and easy!"
Look for the Bull Search app in an app store today. After the initial download, an internet connection is not required for search or sorting bulls.
To help with your next beef cattle synchronization project, GENEX has compiled answers to the most frequently asked questions.
There isn't an easy answer to this question. Research does suggest some protocols perform better than others, but just because research says it's the best protocol doesn't necessarily make it the best protocol for your operation.
Instead, ask yourself these three questions before choosing a synchronization protocol:
» How many times am I willing to put the female through the chute?
» How much am I willing to spend on synchronization drugs?
» What are my expectations for results?
Once you know the answers to these questions you can objectively analyze which synchronization program best fits your operation. No matter what the research or experts tell you, the best protocol for your operation is one that aligns with your goals and one you are 100% confident you can perform perfectly from start to finish.
The answer depends if you are synchronizing heifers or cows.
Criteria for synchronizing heifers:
» Should have achieved at least 65% of mature body weight
» Minimum of 50% should have a reproductive tract score of ≥ 4 at six weeks before breeding
If you don't have a veterinarian in your area that offers reproductive tract scoring, don't panic! You can achieve the same thing by visually observing your heifers for heat in the weeks and months leading up to breeding. You want to observe that at least 50% of heifers are cycling six weeks prior to breeding.
Criteria for synchronizing cows:
» Body Condition Score of ≥ 5 at calving
» An average postpartum interval of ≥ 40 days at the beginning of the protocol
» A minimum of 21 days postpartum at the time of Eazi-Breed™ CIDR® insertion
» Low incidence of calving difficulty
Synchronization drugs should be given in the muscle (IM), with the exception of LUTALYSE® Hi-Con which can be administered IM or subcutaneously. When administering synchronization drugs, it is recommended to use a 1-1/2 inch, 18-gauge needle. You should also wear gloves when handling synchronization drugs to avoid contact with skin.
CIDR® inserts are labeled as a one-time use item by the manufacturer, and it is recommended that you follow this guideline. CIDR® inserts can be one of the most expensive parts of a synchronization protocol (retailing at $10 to $12) and it is tempting to cut that cost in half by using it a second time, however if tempted ask yourself what another A.I. calf is worth. It’s likely a lot more than $5 to $6.
Your pre-breeding vaccination program is an important part of an overall successful A.I. program. However, several studies have shown injection of naïve heifers with a modified live vaccine (MLV) around the time of breeding result in ovarian lesions and decreased pregnancy rates. Therefore, it is recommended that you give all pre-breeding vaccinations at least 30 days prior to breeding.
While there isn't any research that suggests administering dewormer at breeding will have a negative impact on fertility, plan to do that at least 30 days prior to breeding as well. The less stress you put on females around breeding time, the better your success. To achieve optimal results, it's best to do as little as possible to the females during the synchronization and breeding process.
The most critical time for embryonic development occurs between day five (when the embryo begins migrating from the oviduct to the uterus) and day 42 (when the embryo has made definitive attachment to the uterus). Research indicates shipping your cows during this critical time can cause a 10% decrease in pregnancy rates. The best time to move cattle is prior to insemination or days one to four post-breeding. If you can't move them within this time period, it's best to wait until after day 45.
Despite what research might say, no single synchronization protocol fits every operation. Know your operation, follow the suggestions above and trust your gut. And, if you have any questions, don’t hesitate to contact your local GENEX representative.
Many issues can impact an animal’s ability to show heat. If you feel you are not finding cows in heat, it might be time to take a closer look at the issue.
First, you need to determine if the problem exists throughout the entire herd or within a specific subgroup. To do this, analyze your dairy's computer record system. Look at records for reproduction and events that have happened by lactation or lactation group. Once the group in which the problem exists is determined, you will be better able to find possible causes and solutions.
Here are some potential causes to consider:
Slippery floors can be a deterrent to cows exhibiting heat and can also cause injury to animals. Generally concrete is the most common flooring surface in dairy facilities. To make concrete flooring more cow-friendly, one could groove or scabble slippery floors. Caution must be used when using grooving or scabbling floor options, as not to make the surfaces too abrasive on hooves. Another option is to use grooved rubber belting or similar rubber products.
Lameness causes stress on an animal. Lameness also tends to cause animals to lie down and eat less. Obviously, if an animal lies down more, it becomes more difficult to observe signs of heat. And, if an animal eats less, lameness can cause a cow to lose body condition.
A one-point loss in body condition can inhibit an animal's ability to exhibit heat. Keeping the ration adequate to prevent body condition loss is critical. Remember a cow is a mother; she needs enough energy to produce milk (feed her calf) before she will want to reproduce again.
The higher the number of pregnant cows in a pen the lower the amount of estrus that is shown; pregnant cows and cows in mid-cycle are much less likely to mount cows in or near heat. A possible solution for this issue is to maintain a higher percentage of open cows within the breeding group.
The more metabolic problems an animal has when freshening, the greater probability of anestrus. According to research, clinical ketosis, dystocia and retained placentas are associated with more days to first service and a lower conception rate at first service. Overcrowding of transition groups may also lead to more metabolic problems at or after calving.
Some estimates place undetected heats on farms in the USA at 50%. One solution for the issue of failure to properly observe estrus may be to adequately train employees in heat detection technique. In regard to specific timeframes for observing animals for heats, the proper time to observe animals is not while they are eating; instead, for best results, it should be every employee's job to make sure they observe animals at all times and properly identify the animals in heat. If herds are housed in stanchion barns, they need to be turned out daily, to conduct proper heat detection.
It is harder to detect heats during times of extreme high temperatures, and if you are able to catch them in heat, many have a hard time staying pregnant. A solution is to engage in heat abatement strategies, which may include sprinklers, fans, tunnel-ventilated barns, or multiple water sources for cows on pasture.
In conclusion, there are many different factors that could cause you to say, "My cows are not showing heat and conceiving the way they should." To overcome the obstacles, drill down through all layers to find the source of the problem - problems that could relate to the cows not showing heat or people not heat detecting correctly. Several products are also available to aid in heat detection such as Reveal™ Livestock Markers, Allflex® Livestock Intelligence cow monitoring systems, heat detection training and more. Work with your local resources (veterinarian, GENEX representative, etc.) to determine your challenges and the right fix for your operation.
