Semex's Repromax™ Featured In Holstein International

In the August 2009 Holstein International Semex's Repromax™ product was featured as a reproductive solution for dairymen around the world.

Magazine editor Stephan Schneider writes, "The fact that the basic concept behind the product Repromax™, developed by Semex, differs from those of many other suppliers results from its international alignment and the mix of information sources."

"In total, fertility information on over 3,000 bulls (including Jersey bulls) is hidden behind the Repromax values calculated by Semex scientists. Repromax is a fertility index combining the non-return rates (NRR) from Canada, Agri-Tech analyses (ATA) from 12 western US states, and the SCR proofs (sire conception rate) calculated by the US data center within one value from August 2008 on."

Five Benefits of Excellent Reproduction

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst

Achieving excellent reproductive performance is hard work. Here is a quick reminder about the benefits of working hard and delivering excellent reproductive performance in your herd.

1) Higher reproductive performance equals more milk. The average cow in your herd will spend a great portion of lactation near peak performance. Remember, every day open past 100 days in milk cost you approximately $4.50 US per day per cow.

2) Reduce reproductive culls of profitable cows. With more pregnancies occurring, you will have less forced culls due to reproductive failure, giving your herd more culling options. More culling options provides you the opportunity to cull less profitable cows, such as ones with low milk production.

3) Increase the number calves being born each year. With an increase in the number of pregnancies, your herd will have more heifers. These extra heifers can replace less profitable cows, be sold for more revenue or expand your herd from within.

4) More calves being born equals faster genetic improvement. Top daughters will enter your herd sooner, giving your herd a genetic edge.

5) Decrease transition cow problems. Cows that have long lactations and dry periods are at higher risk of developing health problems during their next transition period. Strong reproductive performances can reduce the number of cows that have extended lactations, providing you with less future transition problems.

Semex Adds Breed Leading Jersey Sires

Jersey breeders talk a lot about outcross in the Jersey breed, and have incorporated bloodlines from around the world including the Danish bloodlines that now dominate the top of the JPI listing. Considering the impact of Jace, one is left wondering where to find the new outcross sires.

Semex is thrilled to release two bulls that will outcross on most of the top 100 JPI bulls available today. The first is a bull that is now ranked #1 LPI by quite a distance, 0200JE00430 Lencrest On Time and second is 0200JE00018 BW Bombardier.

On Time is a Sultan son out of the well-known Declo Belle, and elite brood cow that has already given us the impact sire 0200JE00423 Lencrest Blackstone. With On Time you will be using a sire that not only will produce the show winners, but he will also make you money at home with 815 pounds of milk after the MACE conversion, plus for both component percentages and Productive Life, proving that these cows will last.

On Time is not only the perfect mating for Jace and Danish bloodlines, but will work on the Action daughters without taking away what you love about them. Semex has been using On Time extensively as a mating sire, showing confidence and belief that he just may be the most balanced bull on the market today.

BW Bombardier is a WF Brook Bomber x BW Montana Nicole x BW Berretta Prize, the same cow family that has brought to the Jersey breed high profile, impact sires such as Country, Blaise and Carrier. Bombardier could arguably be the best JUI bull the Jersey breed has ever had coming in at an amazing 10.47 for JUI. He sires ... Read More...

Semex Introduces Health$mart™ Sires To Reduce Dairy Expenses

Working with dairymen around the world, Semex knows that today’s tight dairy economy has left dairymen searching for answers to reduce their expenditures and increase profitability. Looking at herd expenses one can quickly determine that health issues have a detrimental effect on a dairy’s ledgers. 

Removal of animals from the herd, whether voluntary or involuntary, is an expense most dairymen are looking to reduce. Replacing that animal and filling her stall is a costly venture. In 2008 De Vries and Olson obtained DHIA lactation records from 38 states from Dairy Records Management Systems and estimated that the national average cull rate was approximately 33%. Meaning, roughly 1/3 of all cows on these farms studied left the herd each year.

Increasing the herd’s survivability and decreasing the involuntary cull rate, therefore, is key to increasing profitability.

“At Semex, we’re working to help the dairyman increase his profitability,” says Nicolas Caron, Semex Alliance Geneticist. “One of the quickest ways to reduce costs and drive up profits is by reducing cows leaving the herd.  In today’s economic market, losing heifers in their first lactation before they’ve returned on your investment is not an option.  We’re working to deliver the very best genetic solutions, and Health$mart sires are selected to give dairymen an excellent option to help reduce costs at the ground level.  Simply put, healthy cows cost less.”

Semex has identified Health$mart™ sires as those that sire the most valuable and ... Read More...

Semen Care: Proper Handling = More Pregnancies

SEMEN CARE: PROPER SEMEN HANDLING = MORE PGS
Don’t let semen handling be a “forgotten link” in your herd. Below are 12 steps herd owners and managers, herdsmen, inseminators and professional AI technicians can put in to practice to help get more cows pregnant.


Locate all items necessary to thaw semen and perform AI, including tweezers, water bath and thermometer, AI gun, sheaths, scissors, paper towels, plastic sleeves, and lubricant. Work close to the liquid nitrogen tank, preferably in a clean and dry location.
Check the water bath temperature using a thermometer. Most semen packaged in .5-mL or .25-mL straws should be thawed in water 95˚F/35˚C.
Keep an accurate semen inventory including storage location.
Work at or below the frost line in the neck of the tank to minimize the possibility of premature thawing of semen straws. After locating and grasping the desired cane, remove the straw with tweezers. Quickly transfer the straw to the water bath, while gently lowering the cane back into the canister, and the canister back into storage position. When thawing more than 1 straw simultaneously, do not allow straws to touch in the water bath.
Semen should be thawed for a minimum of 45 seconds. Use a watch or clock to monitor the ... Read More...

Recording Disease Key In Solving Conception Problems

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst

Often when a herd is having reproductive problems focus is given to what is currently happening to the cows in the herd.  Sometimes, however, looking back on our historical data we can find the root causes of many fertility issues.

The transition period, for example, is the most critical time in a cow’s lactation.  It’s during this time that cows are at a higher risk of developing disease; and, disease during the transition time can lead to reduced production and fertility throughout the entire lactation.

During a herd visit last winter, we visited a dairy with excellent disease recording and calving information.  Unfortunately, though, this herd was battling reduced conception, especially at first service.  Luckily, part of their disease recording protocol included documenting all diseases that occurred to their transition cows.  To detect problems in the herd, an accurate starting point needs to be determined.  Having recorded all disease information using a herd management program such as Dairy Comp 305, an owner, herdsman or herd advisor can more efficiently pinpoint reproduction problems and their causes. 

With this information available, we began to see that a significant percentage of the cows experiencing conception problems were the same cows that had problems at calving.  We identified that a group of cows that had Metritis during the summer ... Read More...

Semex's Maughlin Storm Still Making Headlines

Semex’s iconic Maughlin Storm continues to make headlines more than 13 years after his initial proof as his 800th daughter scored EX this week.  Keriday Storm Sasha, like the 799 Storm daughters before her, has shown exceptional development, durability and strength netting her a score of EX-91-CAN in her fourth lactation. 

An original Semex Master Series™ sire, this most recent accomplishment sets Storm well above all other sires in Canada, as the sire with the most EX daughters ever.  By comparison, his sire Madawaska Aerostar has 53 EX daughters from 22,856 classified and his grandsire, the breed patriarch Hanoverhill Starbuck, has 418 EX daughters from his 37,960 classified. 

Storm’s statistics speak for themselves with 800 EX daughters of his 42,899 daughters classified, giving him an incredible 69% Good Plus or better ranking still today.  Among these daughters are some of the most tremendous and high impact cows of our time.  These cows have been and still are bull mothers, record milk producers, index toppers, brood cows, barn favorites and show winners.  Real cows working around the world.

As a sire of sons, Storm has proven himself again and again, siring nine Semex sires including modern day Master Series™ sires 0200HO07030 Ladino Park Talent *RC, 0200HO03067 Pursuit September Storm *RC, 0200HO04624 Brigeen Givenchy and former #1 ... Read More...
