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...

Semex Master Series™ Sire Buckeye Works at Lansi Farm

As a Semex Master Series™ sire 0200HO04779 R-E-W Buckeye has proven himself time and again.  With his second crop behind him, backing up his proof, we know that Buckeye has stood the test of time, exceeded breeders’ expectations and is poised to make an impact on dairies seeking bulls with durability, reliability, efficiency and profitability assured in their proof.  Buckeye daughters are the real cows on real dairies that dairymen love to work with. 

Sylvain Landry’s Lansi Farms in Saint-Albert, Quebec has 958 head with his 370 cows milked by six robotic milkers.  Sylvain’s Buckeyes are low-maintenance cows that work hard and breed back easily, contributing positively to the herd’s bottom line.  Experience has shown Sylvain that that his Buckeye daughters are positive contributors that increase his profitability.    

"We have 83 registered Buckeyes,” says Sylvain Landry Lansi Farms owner.  “Right from birth, we were immediately impressed by Buckeye’s calving ease.  These calves weren’t very big, but they showed lots of vigor and will to live.  We’re now milking 22 Buckeyes.  They are very consistent and we love working with these young animals. They are very lively and are aggressive eaters who have adapted very well to our environment.  On average, they go to the robotic milker 2.6 times a day.”

“They walk on excellent feet ... Read More...

Popular Sire Pursuit September Storm *RC Passes Away

Semex regrets to announce that popular Red & White sire, 0200HO03067 Pursuit September Storm *RC recently passed away.

As one of several Maughlin Storm sons proven at Semex, September Storm *RC was unique not only in his *RC status, but also because he was a son of the popular Shower family.  His dam was a VG-85-2YR-CAN 4* Astre from the EX-CAN 13* Glen Drummond Shower herself.  This pedigree made him the outcross sire many Red & White breeders had been looking for worldwide, making him popular before he even received an official proof in October 2002. 

September Storm *RC quickly gained popularity in the Red & White show circles and sale rings.  His daughters dominated heifer and milking classes, earning several Premier Sire banners including the coveted Premier Sire Award at World Dairy Expo in 2007 and 2008.  Sale topping daughters by September Storm *RC have made their mark as well, reaching record breaking prices, with Fradon SS Jordan being at the top of the list at $150,000 in 2007.

Most recently September Storm also sired several Black & White show winners including the 2008 Res. All-Canadian Jr. 2 Yr Old, ABF September Cheese VG-89-3YR-CAN, the 2008 Kingsmill Futurity Champion at World Dairy Expo, Miss Macland Sept Juliet EX-91-USA and the 2009 Grand Champion of the European Holstein Show, Planillo September Sara EX-92-ESP, showing his appeal to all bloodlines. 

“Not very often do you have a Red Carrier sire that could compete with the best Black & Whites, so September Storm became popular very fast with Red & White breeders,” says ... Read More...

SEMEXX: It's Worth It!

Aaron Henderson, US Jersey Specialist

In the USA and around the world low milk prices, plummeting equity and lingering high feed costs have left many dairy operators taking a hard look at all costs associated with their businesses, knowing that to be profitable today you have to be more than just efficient.

Cows once worth $2500 US or more are now being sold across the country for $1000 US or less, and springers are now valued at half of what they were once selling for… many times bringing less than $1200 US.

Tough conversations are happening in offices and around dinner tables every day in an effort to increase profitability, whether they’re milking 50 or 5,000 cows.

One of those conversations is whether or not it is worthwhile to pay a premium price for sorted semen, and the added value of producing your own replacements.

Each dairy’s situation is a slightlydifferent, but for Aardema Dairies in southern Idaho, the extra dollars spent is one cost they’re not willing to sacrifice.

The Aardema family along with their General Manager Jeff Wendler, and herd managers John Andersen and Jordan Leak continue to sort through
pedigrees and proofs to find bulls to meet their criteria to use in their herds to make top genetic heifer replacements.

This sifting and winnowing process includes using Semex’s SEMEXX™, gender selected semen.

Buckeye: Definite 2nd Crop Success!

Mike West, Semex Alliance Product Support Specialist & Sire Analyst

Approximately seven years ago the AI industry as a whole purchased many sons sired by the popular Marathon BW Marshall. In October of 2005, Semex graduated several BW Marshall sons, but just one rose to the top of the TPI listing. 0200HO04779 R-E-W Buckeye has maintained his top TPI rankings, making him one of Semex’s most successful sires and another example of Semex’s strong USA proving program.

Today he’s reached another milestone being named a Second Crop success. Buckeye himself was one of the earlier BW Marshall sons to be proven at Semex, and quickly drew international attention as not only a mating sire, but sire of sons. Out of a VG-86-2YRUSA
GMD DOM 2* Rudolph dam, and then a 67,000 kg EX-94-2E-USA Luke, his family’s production capacity has transmitted through the generations. His emergence as a superstar on the international scene was due to his success on the TPI rankings and pedigree appeal with six more generations of VG or EX after the Luke, but also because of the tremendous promise dairymen saw in their Buckeye daughters.
