No Clear Winner In Fertility Race

In August 2008 the United States Department of Agriculture released Sire Conception Rates (SCR) for the first time ever, replacing Estimated Relative Conception Rates (ERCR). The SCR evaluation has proven to be better than ERCR as it is a more accurate measure of a bull’s ability to actually get a cow in calf, as opposed to just measuring non-return rates. Repromax™, Semex’s lineup of high fertility sires, benefits from this new system, as the SCR evaluation is included, forming the world’s only international fertility information.

Semex sires rank well above average for SCR, adding to the confidence breeders can have in using our Repromax™ lineup. The Sire Conception Rate (SCR) rating is an important fertility figure, but should just be part of the decision making process when choosing a mating sire. Therefore, it’s important to keep in mind just what the SCR figure represents. With SCR, the average conception rate for the Holstein and Jersey breeds has been set at 0, therefore a bull that scores 1.0 SCR can be expected to have a 1% higher conception rate than the average bull. And, the opposite is true for a bull with a -1.0 SCR score.

Looking at the industry snapshot of numbers like 1.9… 2.0… 2.1… and 2.3… one wonders how much difference is there between these bulls?

There is a difference of less than half a percet separating the top four competitors in the Holstein breed, and an even smaller difference among the top four competitors in the Jersey breed. These small margins do not lend themselves for any one company to claim complete dominance in SCR rankings.

When is a Bull “Good” or “Bad”?

If only small differences separates so many bulls, technically it is difficult to label one bull better or worse than another for ... Read More...

Semex's Balanced Breeding Gives Dairymen Options

The April 2009 proof release placed the stamp of approval on reliable second crop Semex sires such as 0200HO04779 R-E-W Buckeye and 0200HO03218 Gillette Brilea FBI, while ushering in sires designed to meet the needs of dairymen everywhere. Entering the Semex lineup are sires designed to positively impact bottom lines such as 0200HO09804 Crockett-Acres Eight, sires that meet the needs of Red & White clients, and newly proven sires for those looking for the best proven sons of Semex greats Talent and Titanic.

Buckeye daughters are known for their calving ease, high production, ideal feet & legs and exceptional rear udders, making him one of the most popular BW Marshall sons available today.  The April proof round echoed these same comments dairymen have been making since his release in 2005, and has solidified his place as a Second Crop Success.  Buckeye’s credentials put him in elite ranks for those looking to up their profitability, with +1914M, over 2.52 PTAT, +2.48 for both FLC and UDC, and +2.10 PL and a 6% Calving Ease.  Showing the Power of Balanced Breeding™ and the strength of Semex’s proving program in the USA, Buckeye’s proof has only increased since his initial release, gaining over 140 TPI points overall and adding over 2500 daughters since January 2009.   

Similar to Buckeye, FBI ticks all the boxes for most dairymen, with equivalent figures of +1908M, +2.67 PTAT, +2.05 UDC and +1.90 FLC with +463 NM$ and low 2.76 SCS.  FBI also answers the quest for high fertility, scoring above average on the Sire Conception Rating (SCR) rankings and is a Semex Repromax™ sire.  With over 4000 daughters in his production proof and over 2200 in his type proof, FBI can easily be considered a highly reliable sire. 

Semex’s 0200HO05049 Morningview Ashlar is still one of the breed’s highest ... Read More...
