David and Mina Covert of Prattsburg, New York began dairy farming in the spring of 1977 with just 30 cows. Over the years they’ve grown their operation to 1,036 milking cows and 2500 acres of crops.
Today, Damin Farms LLC includes David and Mina, as well as their three children, spouses and grandchildren. Daughter Keri and her husband Marc Clemons are in charge of the cows and heifers, making all management, genetic and nutritional decisions.
Marc began working on the farm when he was just 13, and with 24 years of experience he’s become a driving force on the dairy. The 1000+ cows are now milked 3x/day and are boasting an impressive herd average of 24,470 3.5% 865 3.0 723 lbs and a 30% conception rate.
A partner in Semex’s young sire program, Premier™, since April 2004 Marc is proud of the results in his herd.
“I think Semex does an excellent job selecting the bulls that they sample,” Marc says. “I am impressed with the number of bulls I have used that Semex has returned to their active line-up.”
Bulls used at Damin through the Semex’s young sire programs include 0200HO01818 Blue- Haven-Ltd Brick, 0200HO05217 Vieuxsaule Malicieux and 0200HO03315 Braedale Pagewire. Marc’s Malicieux daughters have been widely publicized with Damin-Acres Malicieux 1214 VG-86-(EX-MS)-3YR-USA and Keri-Co Malicieux 1212 GP-84-3YR-USA being featured in Malicieux advertising around the world.
Important to Marc is his herd’s longevity and the durability built in by using Semex Premier™ Young Sires.
“We’re happy with the sound, functional daughters we’ve bred with Semex,” comments Marc. “Most of these daughters have outstanding longevity, lasting for several lactations. This is important because we know that Semex is helping us grow the herd internally. We don’t have to go looking for replacements”
“For cows to last for us they have to have good udders, and exceptional feet & legs to take them back and forth to the parlor.”
“We have more Semex sired daughters than any other in ... Read More...

Developing cows that are built to last is key to reducing expenses and increasing profitability on dairies worldwide. These long-lasting, trouble-free cows are the real cows on real dairies that deliver real profitability day after day. They are the favourites on any operation and at the Royal Winter Fair on November 13, they were among the favourites at the entire show.
The Holstein Mature Cow Class was an impressive display of dairy strength and longevity for the thousands of visitors who watched as the 100% Semex-sired class proudly entered the ring. These veterans were sired by seven different Semex sires, known to deliver profitable daughters including: Shoremar James, TCET Lyster, Silky Cousteau, Comestar Lheros, Innwood Terrason, Markim Thunder and Comestar Stormatic.
Led by the 2009 Grand Champion cow, EX-97-2E Thrulane James Rose, who has nearly 64,000 kgs of 4.6F and 3.8P lifetime, each of these cows showed the qualities that spell durability and endurance. They each possess tremendous dairy strength, strong mammary systems and great feet & legs, and an average final score of 94 points, showing that they exemplify long-lasting, functional conformation.
Production drives profitability and these impressive individuals average 43,477 kgs of 4.1F and 3.4P lifetime to date, showing that Semex sires not only deliver long-lasting cows, but also deliver the real cows that deliver real results and real profitability.
Providing the genetics to breed those real cows on real dairies that are profitable and long-lasting is Semex's #1 goal.

The 2009 Semex Walk of Fame as always was the place to be at the Royal Agricultural Winter Fair. Hundreds of international guests visited the display, as well as Canadian country music stars Michelle Wright and Doc Walker, who both took their turns milking a cow. Additionally, Prince Charles, who made a brief stop on his busy tour through the fair to see Semex’s Walk of Fame cows, paid a Royal visit. Most importantly, dairymen from around the world visited Semex's display and reviewed the outstanding display of Semex sired daughters. Selected for their ability to sire healthy, long-lasting daughters, this year’s display featured 10 different Semex Holstein sires with daughters from very different environments. These 10 sires represent the best from Semex and their daughters showcased Semex sires’ ability to work everywhere: Anchoring the row was a daughter of 0200HO04608 Regancrest-MR Samuelo, Extondale Samuelo Fiona VG-88-2YR-CAN. Fiona was 2nd Milking Yearling at the 2009 World Dairy Expo and was able to display Samuelo’s proven ability to sire balance while maintaining excellent mammary systems and foot structure. As a Repromax™, Master Series™ and Health$mart™ sire, Samuelo demonstrated why he is the complete package, ready to work everywhere. 0200HO09804 Crockett-Acres Eight had an exceptional uddered daughter in the display in Buttermoor Apricot Eight VG-86-3YR-CAN.

The Royal Agricultural Winter Fair traditionally marks the end of the North American show season and is the culmination of 364 days of hard work by both breeders and exhibitors. The 2009 Canadian National Holstein Show was no exception as Judge Barclay Phoenix assisted by Judge Roger Turner placed 321 of North America’s finest Holsteins.
Semex sires out shown all others with extremely impressive results. Virtually dominating the show, 95 of the 157 individuals in the top 10 in their respective classes were Semex sired. These 95 individuals included 13 class winners and seven of the nine champions, representing 25 different Semex sires, showing not only our strength but also Semex’s influence and the respect our bulls have earned throughout North America.
In the heifer classes, Semex sires were predominant, with six of the seven classes going to Semex sires. Braedale Goldwyn quickly showed why he is still the world’s most highly demanded sire and the most hotly anticipated sire of sons as he began his early path to the Premier Sire Award.
His daughter T-Triple-T Gold Prize once again won the Intermediate Yearling Class and defended her Junior Champion title earned last month at World Dairy Expo. Honourable Mention Jr Champion was awarded to Philmardo Watch Out Im Here, the 1st place Jr Yearling sired by Semex’s Gillette Watch Out.
The milking classes were heavily influenced by Semex sires, with Goldwyn leading the way in the young cow classes, siring all the winners in the Intermediate Champion lineup.
Fine details separated many placings, with the judges choosing the winning Jr 3 Yr Old, Salem Goldwyn Theresa, as the Intermediate Champion, the winning Sr 2 Yr Old, Sherona-Hill-JH Rachel, as Res. Intermediate Champion and the second place Jr 3 Yr Old, ABF September Cheese, as the Hon. Mention Intermediate Champion.
“These cows send chills up my spine,” said Judge Barclay Phoenix. “They are the epitome of what dairy cows are supposed to be. They’ve got ... Read More...

Amid a week of champions at the Royal Agricultural Winter Fair, one Semex sired daughter stood above others attracting international, mainstream media attention.
Like other famous celebrities featured on CNN and CTV, this famous Braedale Goldwyn daughter now just goes by just one name… “Missy”.
Selling for $1.2 million dollars at the “Morsan Road to the Royal Sale” on Wednesday, November 11, attracted international attention as Eastside Lewisdale Gold Missy VG-89-2YR-CAN went down in the record books as the most expensive cow ever sold. But for Holstein enthusiasts worldwide, Missy was already a household name.
“We’ve been working with Missy and the folks at Morsan in Alberta for over a year,” says Semex Sire Analyst Mike West .
“She’s a tremendous individual who really is the complete package for us. She has what all breeders are looking for… She’s from an outstanding cow family, has top-notch genetics and show-winning appeal. We’re looking forward to working with her new owners and further developing her through her sons at Semex.”

Mark E. Carson BSc. (Agr). MSc., Gencor Herd Reproduction Analyst
When analyzing a herd’s reproductive performance, it’s important to know what heat detection tools are being used to select cows for breeding and then also the subsequent performance of these tools.

Take an example of a herd using a combination of observed heats, electronic activity monitoring and Ovsynch to breed their cows. For this particular herd, the breedings must be categorized as one of the following:

Observed heats
Activity monitored
First service synch
Re-synch

My preference is to categorize first service synch from re-synch cows (timed A.I. used on second breeding or above). This allows me to gain additional insight into the performance of timed A.I. protocol.

Categorizing breedings provides you with two key pieces of information about your herd:

The number of cows being submitted by each tool
What the conception rate is for each method

Having this information helps you make better reproductive decisions by knowing both what tools are working and also what tools need improvement.
For Dairy Comp 305 and Scout users, activating the Breeding Code feature will help categorize and track breeding the performance of each breeding tool. If you’re not tracking how your cows are being submitted for breeding, work with your herd veterinarian or Semex representative to help set up a system to collect this valuable information.
