For the vast majority of Holstein breeders, success is not about winning first prize at a cattle show. What they do want are heifers and cows in their herd that efficiently convert high forage based diets into growth and milk products that consumers will buy.  For those breeders tall animals are not the ideal. In fact many breeders are saying that they want cattle that have more heart and lung capacity (Read more: 5 Things You Must Know About Secretariat, Lung Capacity and Dairy Cattle) and less stature to go along with high production, improved reproduction and functional udders and feet and legs. (Read more: Feed Efficiency: The Money Saver)

Moderating Frame

Since size, stature and strength are some of the more heritable type traits in the North American type classification evaluations; it is possible to moderate stature and increase the capacity of chest and heart and lungs depending on the sires used. The challenge is to do that while placing major emphasis on production, health and reproduction traits. As udders and feet and legs have been improved significantly over the past twenty years in herds focused on producing milk, there is less need to place as much emphasis there. As always there are no perfect sires, so it takes careful corrective mating. Instead of generation after generation of breeding for increased stature, it may require that breeders use some sires that are negatively rated for frame traits. (Read more: Are Today’s Holstein Cows Too Tall?)  Today the majority of sires have high ratings on stature than on strength (USA) or chest width (Canada). To increase strength and capacity the sires used need to have higher indexes for strength or width than for stature.

Sire Suggestions

If your dairy breeding model is about production, efficiency and functionality from heifers that are 1150 pounds and 55 inches, calving at 21 months and cows that are up to 1600 pounds and 58 inches at fourth calving, then here are some sires that may suit your needs. The first requirement for making this list was that the sire have a high CM$ value. Cheese Merit was selected instead of Net Merit as the increased global demand for milk will likely come from the protein content.

Bryhill Science P

(200HO06584, Uno x Shottbolt x Goldwyn x September)

Science will be attractive to breeders wanting to introduce the polled gene into their herd. For a polled sire, he has high ratings for CM$ 756 and gTPI 2297 (71%Rel). His stature (+1.79) and strength (+1.20) ratings are moderate so, except for tall and large framed cows, he will hold but not decrease those traits. His inbreeding is slightly above average given his sire stack. His strengths are udders (+2.50), fat (89) and protein (42) yields with good Productive Life (+4.1) and PTAT (+2.75). His pins are high, but his DPR is +0.8 otherwise he has no significant limiting factors.

Bush-Bros Mog Fairfax

(14HO07349, Mogul x Freddie x Lancelot x Nitro)

Fairfax has a high rating for CM$ 974 with a moderately high rating for gTPI 2359 (71% Rel).  His stature (+0.49) and strength (+0.24) ratings are breed average which leads to a lower gTPI given his fat (73) and protein (42) yields. He excels for DPR (2.4), SCS (2.66), PL (7.0) and Calving Ease (5.6). Breeders who are wishing to have average framed cattle that have good udders (+2.36) with non-traditional sires back in his sire stack and desirable management trait ratings should look up Fairfax’s proof sheet.

Cogent Supershot

(224HO02881, Supersire x Robust x Shottle x Aerostar)

Supershot has been a very popular sire for IVF programmed females over recent months. At CM$ 1110 (highest on this listing) and gTPI 2625 (71% Rel), he is at the very top. Currently, his semen price is very high but breeders willing to wait can expect it to decrease. His stature (+1.07) and strength (+1.01) ratings indicate he will leave moderate framed cattle. His strengths are milk (2528), fat yield (100), protein yield (85), PL (7.4) and DPR (1.9). He has no negatively rated type traits, but neither does he excel for type (PTAT 2.2).

Co-op Bosside Massey

(1HO09527, Mascol x Bret x Manfred x Megabuck)

Massey in one of the few sires where his strength proof (1.54) exceeds hi stature proof (+0.94). These ratings along with his 96% Rel gTPI proof (2260) and CM$ 838 make him a sire that breeders wanting strength and production should definitely consider. His sire stack is quite different from other sires in North America. With over 700 daughters in his proof, breeders can expect that his proofs will hold up over time. His SCS proof is excellent (2.52) and he has good ratings for PL (3.7), DPR (0.9) and Udders (2.21). He needs to be protected for high pins and straight rear legs.

Denistier Discovery

(147HO02479, Mogul x Bowser x Toystory x Outside)

Discovery fits the mould well for sires that commercial dairymen wanting less frame should consider using with stature (+0.52) and strength (+0.07). His sire stack is enough different so as to not be a concern about inbreeding. He has excellent ratings for Management Traits – CE 5.5, DCE 5.4, PL 7.4, SCS 2.63, DPR 2.9, and Rump Angle 1.94 and good indexes for milk (1512), fat (65), protein (51) and feet & legs (2.49). In total, he has a very high CM$ 950 rating and a relatively high gTPI 2415 (72% Rel). He will need protection for straight rear legs (-2.25).

De-Su LTM Rodgers 11379

(7HO12023, Lithium x Russell x Wizard x Mtoto)

Rodgers has an uncommon sire stack and excels at CM$ 1008, and his gTPI is high at 2450 (72% Rel). With stature at 0.86 and strength at 0.12 his daughters can be expected to be medium for frame. As with other sires in this listing, he has very high Management Trait indexes – PL 7.7, SCS 2.65 and DPR 2.7. His Maternal Calving Ease at 3.9 is excellent, and his Calving Ease at 5.8 is very good. His milk (1626), fat (86) and protein (57) are also very good. His overall type. PTAT 1.68, is only slightly above average yet he has no serious type weaknesses.

EDG Rubicon

(151HO00681, Mogul x Robust x Planet x Bolton)

Although Rubicon’s sire stack contains many heavily used sires, his CM$ 1004 and gTPI 2531 (72% Rel) standout with moderate ratings for stature (1.50) and strength (1.15), and it warrants his inclusion in this listing.  PTAT 2.68, UC 2.41, FLC 2.54 and PL 6.3 say that his daughters should be trouble free cattle. Breeders desiring medium framed cattle with all other traits well above average should look up Rubicon.

Farnear Alfalfa

(29HO17516, Supersire x Freddie x Shottle x Buckeye)

Alfalfa’s indexes for stature (-0.26), strength (-0.07) and body depth (-0.72) make him the kind of bull breeders wanting to genetically decrease the frame of their cattle should consider using. He has high indexes for CM$ 935, gTPI 2354 (73% Rel), Milk 1622, Fat 71, Protein 49, PL 8.9, DPR 1.3 and MCE 4.6. His full brother Farnear Admiral (7HO12233) has very similar ratings and could also be considered.

Gillette SGO Myspace

(200HO10003, Mogul x Planet x Bolton x Shottle)

Breeders wishing to breed medium framed cows, but not wanting to move away from the breed’s popular sires might consider Myspace.  With stature at 0.69 and strength at 0.22, he fits this listing.  He has high indexes for CM$ 913, gTPI 2402 (73%), Milk 1805, Fat 82, Protein 58, PL 6.9, MCE 5.5 and SCS 2.68. He has good ratings for PTAT 2.46 and DPR 1.0, and he indexes are all positive except for very slight negatives for teat length and set of rear legs, side view.

Mainstreet Manifold

(200HO00042, Oman x BW Marshall x Emory x Adan)

Manifold is a 97% Reliability sire with a unique breeding pattern. Strength at 1.53 and stature at 0.59 says that his daughters are stronger than they are tall. He is just the type of sire that breeders who are wanting to breed for strength, but not for stature should be considering. He is a calving ease specialist (3.7) with good ratings for CM$ (761), gTPI (2188 (97% Rel), PL (4.3) and DPF (1.2).   Breeders should expect to get daughters that are average for type (PTAT +1.18).

MR Mogul Delta 1427

(203HO01468, Mogul x Robust x Planet x Elegant)

Although Delta is rated slightly higher for stature (+0.81) than strength (+0.04), he is just breed average for both of them. He makes this listing because of his extremely high ratings for CM$1076 (second on this listing) and gTPI 2567 (73% Rel) even though he is only average for frame traits. His strengths that get him highly rated for total merit include milk (1643), fat (93), protein (60), PL (7.8) and SCS (2.60) His DPR is 1.2 and, beyond the frame traits, he is positively rated for all type traits (PTAT 2.75).

MR Moviestar Mardi Gras

(534HO00025, Mogul x Planet x Shottle x Oman)

Mardi Gras is slightly higher for stature (+1.31) and strength (+0.78) than most sires in this listing, these traits are rated much lower for his other type ratings. His specialties are CM$ 926, gTPI 2467 (72% Rel), udders +2.96, PL 6.9 and DPR 2.3 with good rating for all other evaluations. His sire stack contains extensively used sires, but his EFI is not high.

RH Superman

(200HO07846, Supersire x Man-O-Man x Baxter x Durham)

Superman is not yet a year old and semen is not yet available but he is a bull to watch for in the future.  His Canadian indexes include Stature +2 and Chest Width +8 which would indicate that he would be the type of sire that needs to be included on this listing. He is rated at 3525 for gLPI (65% Rel) which puts him at the very top. Other traits with 99%RK ratings include Milk 2564 kg, Fat 126 kg, and Protein 96 kg. Traits with 98%RK ratings are CONF 11, Herd Life 113 and DCA 110.

River-Bridge Co-op Troy

(1HO11056, Mogul x Freddie x Mascol x Trent)

Troy is another top sire with CM$ 1057 (third highest on this listing) and gTPI 2508 (72% Rel) that is only average for strength (0.34) and stature (1.06). His strengths include PL 8.6, SCS 2.50, DPR 2.7, UC 2.37 and FLC 2.50. His only limiting factor is straight rear legs -2.07.

Westenrade Altaspring

(11HO11437, Mogul x Gerard x Mascol x Laudan)

Altaspring is the highest rated type sire (+2.82) on this listing yet he is only above average for strength (1.10) and stature (1.62). He is high for CM$ 967 and very high for gTPI 2546 (71% Rel). He is an all-round bull with no significant weaknesses in all his indexes.

There’s a Pattern

Eleven of the fifteen sires on this listing are sired by Mogul (8) and Supersire (3). That should not be a surprise given that for frame traits these two sires are not highly rated. Mogul is rated (USA) Stature 1.59 and Strength 0.79 and (Canada) Stature 1, Chest Width 1 and Height at Front End -6.  Supersire is rated (USA) Stature 1.25 and Strength 0.91 and (Canada) Stature 0, Chest Width 5 and Height at Front End -4.

The Bullvine Bottom Line

As Mogul and Supersire have been used extensively as the sires of A.I. bulls in the past few years, breeders can expect to have more strength bulls available in the future than there have been in the past ten years. Breeding for width and strength are likely to be topics that discerning breeders will be breeding for in the years ahead.

Proven Sire Highlights

Robust jumps to the top of the gTPI list.  Robust goes from #5 to #1 with the addition of 201 daughters for production and 140 daughters for type.  Milk went up 174 lbs.  Fat went up 15 lbs, and protein went up 11 lbs.  while type dropped slightly to +1.88 (down 0.07). Since his debut in August 2013, Robust has gone from #6 to #5 to the current #1 position.  Dorcy, Bookem and Massey all drop one spot but their numbers hold strong.  The highest new release proven sire goes to AltaGreatest (read notes below).  Freddie is #6, AltaIota #7, AltaMeteor #8 and Hill #9.  The second highest new release sire is Picardus at #10 (read notes below). A Casualty of the April Proofs is unfortunately Ladys-Manor PL Shamrock who slips from #8 position to #46.

Robust also jumps to the number #1 spot on the NM$, followed by former number #1 Erdman and Twist who is now #3.  New release sire Yano comes in at #4.  Jarvis #5 and Freddie #6 hold their ranks with another new comer Diesel debuting at #7.

G W Atwood holds on to his #1 position on the conformation list.  Absolute-Red moves ahead of Sabathia to take the #2 spot.  Golden Dreams and Braxton hold on to the #4 and #5 spots with Gold Chip debuting at #6.

Closer look at new release proven sires:


Planet x Bolton x BW Marshall

The highest new release sire is Den-K AltaGreatest (Planet x Bolton x BW Marshall). He comes in at #5 gTPI on the US proven list.  From the Den-K Rudolph Cub Kiddy EX-91 2E GMD DOM family.  An extreme production sire with high components, AltaGreatest also has functional type.  Look for AltaGreatest daughters to have shallow udders with strong suspensory ligaments.  One area the AltaGreatest daughters will need to be protected on is their rump angle and pin width.  AltaGreatest will work well on your straight legged cows, as long as they have good foot angle. AltaGreatest has already been used as a sire of sons with such notable sons as Co-Op Upd Greatest Lifelong  (GTPI +2312), Farnear Briley Boy (gTPI +2273) and Farnear AltaBuzz (gTPI +2248). Interesting to note that AlaGreatest official proof is within 60 points of his initial genomic proof back in April 2011 of gTPI +2315.






PicardusPine-Tree Picardus
Planet x O Man x Rudolph

The second highest new release sire comes from the Wesswood-HC Rudy Missy-ET TV EX-92 3E GMD DOM family.  Picardus’ dam is an Oman daughter of Missy.  As his sire stack would indicate Picardus has a strong production proof with good components.  Picardus daughters are solid with open ribs and high wide rear udders.  One area that he will need to be protected on is his feet and legs.  Low foot angle combined with slightly sickled rear legs means he will need to be correctively mated for this. Picardus official daughter proof is only 31 points below that of his initial genomic proof in April 2011 at +2239.









YanoCo-Op Upd Planet Yano
Planet x Bret CV x Manfred

A product of the Co-Op breeding program, Yano debuts at #3 on the NM$ list.  Yano is the Planet brother to the very popular Massey, sired by Mascol.  Not surprisingly then Yano daughters are extremely durable with strong health and fertility traits.  Yano daughters will work well in a commercial environment though they may lack the dairy strength that some would expect.  They are not tall and can tend to be weak loined.  They do however have extremely strong udders with lots of ligament and snug attachments.









DieselJuniper Planet Diesel
Planet x O Man x Durham

Diesel’s dam has been a very popular bull dam in Europe with two sons already proven (Malke +1758 gTPI and Dada gTPI +1670).  While not a type improver, Diesel does offer strong components and high herd life.  His low somatic cell and high fertility will certainly make him a management trait improver.  However be careful because his daughters have been slower milkers from time to time.  While his udders and legs are sound, he will need protecting on his dairy strength and median suspensory ligament as well as rear teat placement.







Gold Chip

Gold ChipMr Chassity Gold Chip
Goldwyn x Shottle x Champion

The very popular Goldwyn son from Regancrest S Chassity-ET TL TY EX-92 GMD DOM has been leaving high type daughters that have been winning shows across North America.  (Read more: REGANCREST S CHASSITY – 2012 Golden Dam Finalist) So it’s no surprise that great grandson of Regancrest-PR Barbie-ET TV EX-92 GMD DOM would debut with a strong type proof.  Extensively used due to his well known cow family and strong genomic tests, Gold Chip daughters did not disappoint.  Gold Chip daughters are very tall and angular with great feet and legs and very snug udders.  One area breeders may want to protect Gold Chip daughters on is their depth of rib and width of chest.





Genomic Test Sire Highlights (Enrolled with NAAB)

Making his North American debut, Supershot goes straight to the top of the TPI and NM$ lists.  Supershot is followed by former #1 Alta1stclass and #2 Kingboy who now find themselves in 2nd and 3rd respectively.  Another new comer AltaHotrod finds himself in the #4 spot. Coming in at #5 is an early Cash Coin son Draco.

A closer look at new release genomic test sires:


Supershot-042014Cogent Supershot
Supersire x Super x Shottle

The much talked about Supershot did not disappoint when his official numbers came through.   The pedigree behind Supershot is certainly not well known among breeders with last 5 of his 8 generations coming from Dutch breeding. Behind that is the US cow family at Vir-Clar Holsteins, tracing through the highly acclaimed Tirsvad Patron Claire EX92. He hails from the same line as the famous Koepon Classy’s and Anderstrup Claire family, known worldwide for its ability to breed high-ranking females and bulls on numerous different bases.  Supershot has an extremely high genomic test and his pedigree indicates that he should be able to sire those extreme production daughters many breeders are looking for. Supershot should be protected on milking speed and dairy strength.






AltaHotrodGlen-D-Haven Castle
Jerod x Altaiota x Goldwyn

Another new sire debuting on the top gTPI list at #4 is AltaHotrod. While AltaHotrod does not have Planet, O-Man, Justice and Shottle in his pedigree, he does have Goldwyn.  However, he   is still a relative outcross sire because Jerod and AltaIota were not as heavily used.  Look for AltaHotrod to sire extreme production and conformation, with solid health and fertility traits.   While AltaHotrod daughters will not likely be winning the shows, he does have strong type numbers that will make for a significant type improvement in regards to classification and longevity.  AltaHotrod daughters will need to be protected for teat length.







DracoMr Delicious Coin
Cashcoin x Robust x Planet

Draco is an early Cashcoin son who debuts at #5 on the gTPI list.  Draco’s dam Miss OCD Robst Delicious from the WINDSOR-MANOR RUD ZIP-ET 3E 95 GMD DOM family is quickly proving that she can produce high genomic offspring.  She already has 47 offspring over 3,000 LPI and has other sons, MR Delicious Pre 57512, who will also be joining Draco on the top TPI lists shortly and Delta mentioned below.  Look for Draco to sire strong production with good components and durable type.  While not a health and fertility leader, he is sound in all areas.








DeltaMr Mogul Delta 1427-ET
Mogul x Robust x Planet

Joining Supershot in the over 1,000 NM$ club is Delta.  Delta is a Mogul brother to Draco and is from the WINDSOR-MANOR RUD ZIP-ET 3E 95 GMD DOM family.  Delta offers extreme health and fertility traits with solid type and strong production.  Breeders who are looking for tall framey two year olds will certainly not want to use Delta but he does offer significant udder improvement.  Delta is among the breed leaders for productive life.









BeemerPol Butte Mc Beemer
Mccutchen x Goldwyn x Shottle

A new high genomic type sire from the Barbie family that is sure to get a lot of attention is Beemer.  Beemer’s dam is BUTZ-BUTLER GOLD BANNER – VG 88-2YR who is one of the top cows in the breed for EBV type.  From the powerful Barbie family, Beemer is sure to follow in the footsteps of other family members like Brokaw and receive heavy usage during his sampling period.  At +23 DGV conformation in Canada Beemer is one point below the extreme breed leaders (Read more:The 10 Extreme Type Sires Most Likely To Sire the Next World Champion).  Look for Beemer to sire strong dairy cattle that have great udders and are extremely tall.  While his rumps can be a touch high, they should be fine by show standards.

2014 editors choice graphicEveryone is always looking for the next great sire.  That sire that is going to leave them with the #1 daughter or son on the lists.  The problem is with everyone using the same exact sires, from the same exact lists it can be hard to get ahead.  That is why you need to find those sires that have the ability to leave you with the extremes.

Outlier sires have the ability to throw you the son or daughter that is extremely high on genomic lists, well above parent averages and have what it takes to top the charts.  But they also typically have the ability to miss the mark.  They typically have the tendency to through you the largest extremes, so for every list topper they will leave you some that don’t measure up.  Why this is acceptable is that in today’s genetic marketplace, the revenues from the one list topper typically make up for the costs of the others that don’t measure up.

The following are the top 10 sires we found that offer the greatest rate of acceleration with the ability to produce the extreme son or daughter.


HOUSAM71441918      011HO11425

Every now and then there comes a sire that seems to come out of no where.  Alta1stclass is one of those sires.  From a cow family that many have not heard of, Alta1stclass is certainly a development of the genomic era.  Alta1stclass is the 3rd generation in his family to score at least 5% higher on their DGV’s than their parent averages.  That is saying something in today’s current calculations where those progeny that test  at the extremes are regressed back to the rest of the pack.  While not a high production sire, Alta1stclass has strong components and functional type.  Those looking to breed the next VG-89-2YR will not be impressed with his dairy strength scores and his loin strength.  Alta1stclass will give you strong components, high functional type and great health and fertility.  Which when mated correctly will sure leave you the next generation of extreme progeny.



HOUSAM71813434     029HO17571

Rambo has is it all, he is over 1800 lbs of milk with positive components and a near flawless linear.  More importantly he has extreme health and fertility.  Rambo is a Jerod from a Shamrock then CLEAR-ECHO M-O-M 2150 VG-87 EX-MS @ 2-06 DOM, who is in the top 50 gTPI cows.  Expect Rambo to be the sire of many bull mothers, though as we learned in analyzing sires like Goldwyn and O-Man, there seems to be a strong indication that sires that get the majority of their genetics from their mothers tend to not produce the next generation of sons.  Rambo only gets approximately 41% of his genetics from his paternal side, similar to Goldwyn.  (Read more: Why Braedale Goldwyn Wasn’t a Great Sire of Sons)





HOUSAM72128125     151HO00681

With a sire stack that reads like a who’s who of the genetics world, it’s not surprising the Rubicon will have the ability to throw you the extreme list toppers.  In fact the cow family behind Rubicon has been doing that for many generations with his 2nd dam being SANDY-VALLEY PLANE SAPPHIRE VG-87-2YR-USA.  Rubicon has extreme components with a combined Fat and Protein of +153 lbs and add to that over 2.50 on Type and he is in rare company.  But what really make’s Rubicon stand out is his sire stack that demonstrates the ability to sire extremes.  Similar to Rambo, Rubicon’s Chromosomal PTA’s would indicate that he will make a much better sire of bull mothers than a sire of sons.





HOUSAM71506037     007HO12161

For those of you who are looking for an outcross sire who packs a punch, LADD MAN is your guy.  With extremely low inbreeding and relationship values Ladd Man is certainly the high outcross sire and he is polled.  Don’t let the Man-O-Man in the pedigree confuse you when thinking he may not be an outcross sire as he gets approximately 72% of his genetics from his sire Ladd-P Red and only gets about 8% of his genetics from Man-O-Man as opposed to the expected 25%.  While certainly not a production sire by any stretch of the imagination, Ladd Man has strong percentage protein improvement, solid type and very desirable health and fertility traits.  For those breeders looking for an outcross sire to use on your high production cows, Ladd Man-P is perfect.




HOUSAM71813342     029HO17509

If you are looking for more milk that Ladd Man offers then Octavian should do the trick.  With a genomic test that is 6% higher than his impressive parent averages, Octavian will certainly leave you some chart toppers.  At almost 2000 lbs of milk, over 170 combined lbs of fat and protein and over 2.70 for type and strong health and fertility traits, Octavian is the balanced sire that does it all.  More importantly Octavian is the top balanced breeding sire to get more of his genetics from his father than his maternal side.  Which has proven by sires like O-Man to be a key factor in being able to sire the next generation of sons.







Looking for a shot of production?  Then Supershot will score well for you.  The pedigree behind Supershot is certainly not well known among breeders with last 5 of his 8  generations coming from Dutch breeding.  Behind that is the US cow family at Vir-Clar Holsteins, tracing through the highly acclaimed Tirsvad Patron Claire EX92.  He hails from the same line as the famous Koepon Classy’s and Anderstrup Claire family, known throughout the globe for its ability to breed high-ranking females and bulls on numerous different bases.  Supershot has an extremely high genomic test and his pedigree indicates that he should be able to sire those extreme production daughters many breeders are looking for.  Supershot is also the #1 genomic sire for Net Merit $ 1000.  Supershot should be protected on milking speed and dairy strength.



HOUSAM72254526    007HO12266

If milking speed is a deal breaker on Supershot, then look to Yoder.  Yoder is the extreme sire that is sure to ring the bell.  His genomic test is 7% higher than his parent averages and his production predicted daughter deviations are some of the highest in the breed.   (Read more: The Number That Will Change the Way You Look At Genetic Evaluations Forever…) While results are sure to be highly variable, Yoder will certainly be worth taking that shot on with a large framed high production cow from which you are looking to produce that next generation of extreme production daughters and sons.  How many genomic sires are over 160 lbs of combined fat and protein and over 3 points on type?  Two Yoder and Silver.





HOUSAM72156794     029HO17573

Since Supersire put Seagull-Bay on the map (Read more: Charting the Right Course at Seagull Bay Dairy) everyone has been watching to see just who was going to be the next impact sire from this genomicly gifted family.  Now comes Silver who may just have a greater impact than even Supersire has.  Silver is a Mogul from the Snowman sister to Supersire.  Like Supersire, Silver has the ability to leave extreme production.  And just like Supersire he will have a significant impact as a sire of sons as well.  Ranking in the top 1% of the breed for Milk, Fat, Protein, Type, and Udders tells you that Silver is going to make a lot of noise before all things are said and done.






HOUSAM71181872    029HO17576

At over 1.0 for DPR and 2 points for HCR and under 8 for all calving traits combined with under 2.70 for SCS it’s no wonder that Dreamweaver daughters are going to last (+7.2 productive life).  To go with that Dreamweaver is over 2000 lbs of milk, over 120 lbs of combined fat and protein and over 3 points on type.  Not surprisingly he comes from a cow family that has made many dreams come true, as he comes from the SNOW-N DENISES DELLIA EX-95-2E-USA GMD DOM  5* family, well known for their ability to produce long lived sons and daughters.  Dreamweaver should be protected on body depth, set to their legs and angle of their rumps, but nothing that will interfere with the ability to last many long productive lactations.





HO840M3012171355     147HO02472

In addition to Rambo, Kobra is an extreme health and fertility sire worth looking at.  Extreme components, and high type combined with breed leading health and fertility traits has this cow family emerging on every ones radar.  While not a family that contains generation after generation of VG or EX it is a family that test well genomically.  With Kobra being the third generation at least 5% higher on their genomic test than their parent averages.








The Bullvine Bottom Line

In this era of pushing the genetic envelope those breeders looking to stay ahead, or at least at pace with the large genetic corporations are going to have to use outlier sires.  Sires that themselves have made significant gains over previous generations and have been genetically gifted the with best their parents had to offer.  Breeders are also going to have to exit the land of the safe and start using sires that throw more extremes.  These 10 sires are just those sires.  These sires are the 10 outlier sires that will give you the greatest chances at winning the genetics race.
