CRV bulls reaffirm the confidence of farmers

The introduction of the one-step model as an improvement of the breeding value estimation significantly increased the reliability of genomic breeding values at this proof run. This means that farmers can use the top InSire bulls from CRV’s breeding programme with even more confidence to improve their herds.

For the first time, the red-and-white Delta Wingstar received a breeding value based on the performances of more than 400 daughters. With +0.28% fat and +0.28% protein, they confirm their sire’s qualities as a component sire. Wingstar’s breeding value for productive life rises to +785 days, he has a good all-round score for health traits and improves his conformation traits to 110 total score with 109 for feet and legs.

Wingstar fits into CRV’s FeedExcel breeding strategy for developing a herd that produces higher milk yields, requires less feed, achieves higher profitability and lower emissions. Since the introduction of FeedExcel, there has been rapidly growing interest in breeding for feed efficiency. A large number of farmers have started genomic testing their herd with HerdOptimizer, included FeedExcel into the mating programme SireMatch, by putting more emphasis on feed efficiency, health and longevity in their breeding goals and started selecting FeedExcel certified bulls.

The red-and-white daughter proven bulls in CRV’s line-up definitely add value to the red and white holstein population but also the black-and-white population. And that is also certainly true for a number of young InSire bulls.

The highest red-and-white InSire bull for NVI is Delta Borax. His high NVI score is on account of (among other things) more than 1,500 kg of milk with +0.31% fat, +859 days productive life, 107 total conformation with 108 udder and 106 feet and legs and 111 udder health. The Poppe Freestyle son has a breeding value for feed efficiency of 110, making him a FeedExcel bull par excellence. In Germany, Borax total index of 162 RZG, makes him the number one in the ranking of red-and-white bulls. In Germany, Borax scores 128 for feet and legs.

InSire bull Delta Sunburst is also a FeedExcel bull. His pedigree goes back to the Skalsumer Pietjes, the exact same cow family of which Sunny Boy was also born from. Sunburst sires more than 1,500 kg of milk with positive components, resulting in 168 kg of fat and protein and almost 500 Euros Inet in combination with 113 feet and legs and 111 total score.

Seducer with 112 hoof health, Sparkle with 116 feet and legs

InSire bull Delta Seducer P, from the well-known Caudumer Lol cow family and hence closely related to Delta Launch PP, has an appealing breeding pattern with very high components (+0.71% fat and +0.38% protein), 109 feet and legs and 108 total conformation. This calving ease sire fits into the FeedExcel breeding strategy and also scores well for daughter fertility (104) and excels on hoof health (112).

The new InSire bull Delta Sparkle (Powerlift x Jacuzzi) is a downright asset for the red-and-white holstein population, with an all-round breeding profile with more than 1,000 kg of milk with +0.43% fat and +0.12% protein, positive proofs for health traits and 113 total conformation, with as much as 116 for feet and legs.

This proof run, the homozygous polled InSire bull Delta Primetime PP (Taskforce P x Abundant P) improved his breeding value for milk production. He went up by 2 points for feet and legs, to 112, and also two points for total conformation, to an absolute top score of 115. Primetime is exclusively available through the Create programme.

Primetime PP is a flagship of CRV’s successful breeding programme for polledness. This program results, among other things, in two bulls in the top 10 red-and-white PP in Germany, such as the high component sire Delta Scrambler PP with 151 RZG. Three CRV bulls can be found in the German top 10 black-and-white PP, including Delta Volkmar PP (149 RZG) and Delta Tycho PP (148 RZG).

The black-and-white Willem’s-Hoeve Woody has managed to significantly improve his breeding values this index run; with an increase of 200 kg milk to +2,126 kg of milk (still having positive components) and +22 Euros Inet to 539 Euros Inet. His breeding value for feet and legs has improved by 3 points to 109 and he added 2 points to his breeding value total conformation to 112. He also gained in udder health (108) and hoof health (108). With a breeding value for feed efficiency of 109, the Ranger son is also a FeedExcel bull. With 152 RZG, Woody ranks at the fourth position in the ranking of daughter-tested bulls in Germany.

With Delta Universe P (Drone PP x Woody), CRV already has a polled and very interesting grandson of Woody on offer. He sires high production with more than 2,000 kg of milk with +0.25% fat and +0.20% protein, resulting in more than 200 kg of fat and protein. With a breeding value of 111 for feed efficiency, this FeedExcel bull surpasses his grandfather and with for 109 feet and legs and 106 udder health, he stands out for these sustainability traits. Universe P is already exclusively available through the Create programme.

FeedExcel bull Delta Glory (Perfect x Martin) is also a high-yielding bull with sires almost 2,000 kg of milk and positive components. In addition, this grandson of Midwolder Martin scores breeding values of 111 for feet and legs, 110 total conformation, 107 udder health and 109 hoof health. For persistency, Glory has a unique breeding value of 118.

Delta Nobrainer has made a significant leap forward in his breeding values. He shows an all-round profile at a very high level with (among other things) +0.78% fat and +0.22% protein, 110 udder health and 107 hoof health and +840 days productive life. Nobrainer is also a FeedExcel bull.

Delta Keystone is new to CRV’s line-up. He is an excellent production sire with +1,255 kg of milk with +0.21% fat and +0.17% protein and improves feet and legs (111) and hoof health (111). He sires modest stature which is desired by many dairy farmers and combines this with sufficient width through the bodies. Keystone is a FeedExcel bull pedigreed as Perfect x Ramsey x Benz, making him a sire with a different bloodline.

With his first 72 daughters, Peak Upswing (I-Pursuit x Duke), from CRV’s North-American breeding programme, keeps his genomic breeding values perfectly in line as expected. He sires 739 lbs of milk with +0.26% fat and +0.08% protein and scores 906 NM$ and 2,941 TPI. For the exclusive CRV breeding value hoof health, Upswing scores 107. With 1.87 PTAT, he is an excellent conformation sire, siring wide and ideally sloped rump structures.

With Peak Hammerhead (Overtake x Zazzle), CRV adds an absolute top ranking gTPI bull to its lineup. With 3,210 points, he ranks in the top 25 active and available bulls. Hammerhead shows a complete breeding pattern at a very high level with 1,206 lbs of milk with +0.30% fat and +0.09% protein, 1,172 gNM$ and 1.62 PTAT with 2.11 Udder Composite and 0.95 Feet & Legs composite. Hammerhead is exclusively available through the CRV's Create programme.

Peak Fugleman (Zazzle x Positive), reinforces his position as a well-balanced bull with a very complete breeding pattern, resulting in 3,026 points gTPI. He sires 1,370 lbs of milk with high components (+0.20% fat and +0.10% protein) and also scores 2.08 PTAT. With 108 for feed efficiency and 968 gNM$, this FeedExcel bull will guarantee dairy cows that will pay the bills for their owners. Fugleman has a distinctive aAa code 516.

Fugleman’s half-brother Peak Lavezzi (Zazzle x I-Pursuit) increased to 3,055 gTPI and 1,002 gNM$. Lavezzi is a calving ease sire with 108 for feed efficiency. This FeedExcel bull sires 1,304 lbs of milk with +0.21% fat and +0.08% protein. For the exclusive CRV breeding value hoof health, he scores 107.

CRV also distinguishes itself on polledness in its North-American breeding programme. This index run resulted in two polled bulls with more than 3,000 TPI. Genosource Fug Titus P is a son of Peak Fugleman with 1,064 gNM$. He is a winner in terms of production with +1,557 lbs of milk with +0.18% fat and +0.09% protein and sires A2A2 beta casein and BB kappa casein. Titus P will sire medium stature and the desired curvature to the rear legs. He is a FeedExcel bull with 109 for feed efficiency and high scores for health and productive life.

Wesselcrest Lamont P (High Energy x Limelight P) is an interesting bull that increases components with 1,098 lbs of milk and +0.19% fat and +0.10% protein. With 2.01 Udder composite he is also a perfect udder improver.

The full brothers Peak Hylander and Peak Holymoly (Holysmokes x Big Al) both sire a complete package of production, health, conformation and feed efficiency. Holymoly scores 3,110 gTPI and 1.83 PTAT and sires 160 lbs of fat and protein in combination with good daughter fertility and excellent udder health resulting in 6.5 productive life.

With +23% CRV Efficiency, 176 lbs of fat and protein, 5.5 productive life and 113 feed efficiency, Hylander is an absolute winner for breeding high yielding and efficient herds. With 107 udder health, he is also responsible for easily high producing daughters. Like Holymoly, Hylander is, of course, a FeedExcel bull and is exclusively available through the Create programme.
