A healthy and efficient herd stands at the base of an excellent lifetime production. Genetic progression is the key, and consistent breeding brings results. CRV offers you an extensive sire selection for improving your herd with an excellent lifetime production and high components.

Daughter proven sires confirm predictions
During the most recent NRM, a quite youthful and promising group of Finder was presented by CRV. This August proof run adds another 500 daughters to his proof data, giving Bouw Finder a near total of 750 daughters.
Raising his Feet & Leg score is another highlight! Finder daughters combine a high lifespan (+959 days) with very high components (+0,11% Protein and +0,46% Fat). CRV adds Delta Reporter tot their portfolio, a sire that will breed no-nonsense cows with all-round, efficient (+13%) traits. Reporter (Skyfall x Belfast x Surprise) will combine high production (1.049 Milk) with a big plus in protein percentage (+0,14). Reporters’ daughters will excell in efficiency, carried on very good legs.

The undisputed number one, longevity king Bouw Rocky remains on top (+1148 days) with currently over 300 daughters being in their third lactation. His daughters represent strength and durability, cows that can produce milk with ease and persistence, remaining healthy throughout.

First Ranger sons make promising debut
Double W Ranger solidifies his leading position with great scores (405 NVI). His all-round profile makes him a universal bull to breed with, adding high scores for Conformation (116), fantastic udders (115) and Feet & Legs (111). Catching our attention are a number of Ranger sons  Abundant P RF, Yes, Woody and Wirdum, with high scores for rich milk and conformation, a future promise! Adding Abundant P RF to the sire directory brings opportunities for Red and/or Polled Holstein breeders to use Ranger’s genetics.
Striking catalog debut for Delta Maiko
The previous proof run introduced Delta Maiko as the most prominent daughter-proven newcomer. Delta Maiko (Perfect Aiko x Camion) is daughter-proven and currently available, his proof based on 496 daughters. Combining production (829), components (+0,23% Fat and +0,15% Protein), all-round conformation and positive daughter fertility (103) makes him a universal bull to use. With a plus for milk and protein percentage, high daughter fertility and positive health traits, Delta Maiko also breeds easy-to-manage cows.

Young sires
Delta Pitcher Red (Jetstream x Potter Pp x Aram) transmits very high daughter fertility (107) and udder health (108). He will breed daughters with ideal type, who will produce lots of protein (69kg) with surprising ease. Delta Jacko PP-Red (Leader Pp x Brasil x Snowfever) offers the complete Polled Package, starting with (+11%) Better Life Efficiency. He owes this score to a production of 960 kg milk with good components, combined with a very high expected longevity. Jacko has an overall good health trait profile and his daughters will maintain their production yield.

Premium milk
During this proof run, Delta Listrotto Red (Rody x Maestro RF x Atlantic) has improved himself tremendously on NVI (327), thanks to his high components (+0,22% Protein). Listrotto transmits an excellent longevity, combined with great health traits and strong feet & legs.

Polled newcomer enters MRIJ stage
Meervelder Primeur P
(Don Quichot P x Ewald x Baltimore) carries 75% MRIJ and is heterozygous polled. His daughters have very good type and exceptional udders.

Circular agriculture

New is the idea of ​​circular, or recycle agriculture, not. "Omnivores" such as pigs and chickens used to scrape their food together at the farm yards. "Left overs" from arable farming and from dairy farming and dairy production were thus brought to great value.

The vision of Carola Schouten, Minister of Agriculture, Nature and Food Quality on Dutch agriculture about circular agriculture offers opportunities for cows. The appreciation for sustainable food consumption is increasing, as is the demand for animal-friendly produced products. It is precisely the closing of cycles that makes this possible.

The earth is expected to be populated by 9.5 billion people in 2050. Only with a radical transition can this world population be fed within the limits of our planet. People must find a new balance between the consumption of animal and vegetable proteins. Ideally we extract at least 50 to 60 grams of protein from our food per day. Specific groups, such as the elderly and chronically ill, need more.

In a sustainable diet, about a third of the protein is of animal origin. That is less animal protein than in the current Western diet. Dutch experts argue for the use of vegetable residual flows and "grassland that is not suitable for arable farming" for animal feed.

This prevents waste and reduces land use. Animals can graze land that is unsuitable for growing human food. And they convert residual flows extremely efficiently into meat, milk or eggs. Sources of high-quality protein.

Technology and innovation
But with circular agriculture we certainly do not go back to the past. Recycle farming certainly does not mean that the achievements of new technology remain behind the scenes. Modern Dutch agriculture is praised for its economical use of raw materials, thanks in part to High-tech methods and precision applications. The Netherlands is also known for the so-called optimized carcass value: the use of all animal parts. They are necessary qualities in the endeavor to feed the world and to close the cycle.

It sounds good, but what does it mean for the cow? The Dutch cows can be compared to top athletes; changes in diet make themselves felt in milk yield and quality. With all the knowledge and skills and associated sensor technology that is available in-house, a structured approach is being looked at. So that in addition to enough attention and veterinary care for cows, we also look at our animal protein production with a greater eye for welfare.

Ella 192 and Jose 2 most beautiful cows in the Netherlands

On Saturday 29 June, the National Cattle Show in the Netherlands (NRM) produced two beautiful general champions. Bons-Holsteins Ella 192 (by Seaver) won with the black and whites, Twente Dairies Aplle Jose 2 (Big Apple) won with the red and whites.

For the owners of Ella 192, Nico and Lianne Bons from Ottoland, it was the third time they took the general championship home. In the 2017 edition, Bons-Holsteins Ella 158 (by Mailing), the dam of Ella 192, was the most beautiful black and white cow in the Netherlands. Harrie Tijhuis from Hooghalen, the owner of Jose 2, had managed to reach the highest podium already once before. That was in 2006 with the Convincer daughter Milenium.

Stadel daughter Janet most beautiful 100,000kg cow
At the NRM, the class with a total of 19 cows that gave more than 100,000 liters of milk (!) was won by Welberger Janet 347. Stadel's daughter, owned by dairy farm Wiltink from Nijbroek, is 15 years old and has already calved 11 times. Nevertheless, she was still very youthful with a great udder and well-used legs.
Judge Paul Hannan from Ireland was full of praise for the class with superb old cows. “Ladies” he called them. 'This is what the Holstein breed stands for: cows that can grow old and achieve a high lifetime production. What a treat when you are asked to judge such a class of cows.’


NRM news: Bouw Finder, Delta Fun P and Bouw Rocky

CRV has presented three daughter groups at the NRM: one group with the late-maturing daughters of health specialist Bouw Finder, a group of the Nr.1 homozygous-polled and progeny-tested bull in the Netherlands Fun P, and a group of the reliable longevity specialist Bouw Rocky.
The daughters of Bouw Finder are youthful, still somewhat raw, with fine legs. The shallow udders have ideal teat placement for a milking robot. Dairymen that are using Finder on their young stock do receive somewhat 'slow starters', cows that can easily cope with the production and grow old in good health.

The same goes for the dairy daughters of Fun P. With spacious chests and rumps, shallow and wide rear udders and fine legs with healthy claws, the animals are well put together. The group at the NRM had an average of no less than 87 points for general appearance and they clearly demonstrated how they continue to grow nicely.

Also the third bull in the progeny-group demonstration writes Sustainable and Healthy with capital letters. Bouw Rocky is a longevity specialist, his daughters are persistent and late maturing. With a flat lactation curve they are inconspicuous cows in the barn. They have great udders, use their legs very well and get better with every lactation.

Milk production worldwide will increase by 45 percent
Up to the year 2040, milk production around the world will increase by 45 percent, is the expectation of dairy research organization IFCN. This increase is necessary to meet a rising demand for dairy products, caused by a growing population and an increasing need for milk.
Between 1998 and 2018, milk production has already grown by 63 percent, a conclusion reached by dairy experts from 48 different countries. Fact is, that the present number of companies worldwide (20 million) will start to go down. The farms that remain will have more animals, and will also realize a higher milk yield per cow, so that ultimately more milk will be produced with fewer farms.

Persistent milking for less trouble
Dairy farmers which use persistent milking at their farms say that they benefit in particular from the lower number of calvings, for it results in fewer health problems for the cows and less unforeseen work for the farmers.

This is evident from the "Tailored Lactation" study by Wageningen University & Research into persistent milking, in which 14 dairy farmers, for some time already, are deliberately extending the lactation period at their farms. The reasons for prolonging the lactations are mainly found in the area of cow health. Most health problems occur during calving. In addition, calving cows usually generate a lot of unforeseen labor for the farmers. These problems could be largely avoided by allowing the cows to calve less often. As a result, dairy farmers experience more work pleasure.

Financially, persistent milking not only will make a difference where veterinary costs and labor are concerned, but also with respect to concentrates costs.

Antibiotics use of Dutch cows more than halved in 10 years
Dutch dairy cows produce their milk more and more healthily. The use of antibiotics has fallen by no less than 63.8% in the last 10 years. Especially a more targeted drying off of cows makes a considerable contribution to the decrease. Cows with good udder health do not need antibiotics in the dry period. Previously, all cows were structurally treated with antibiotics at drying off. Thanks to monitoring of the cell counts, also the tank-milk cell count in the Netherlands has steadily fallen to around 180,000 cells/ml in recent years.

Eating cheese reduces the risk of cardiovascular diseases
“Eating cheese is beneficial to one’s health”, researchers at McMaster University in Canada have found. By eating more than two servings of cheese per day, there is a reduced risk of strokes and cardiovascular diseases. Cheese also helps digestion to get going. This was especially true for certain cheeses, such as the Gouda cheese. In the study 130,000 people participated, ranging in age from 35 to 70 years and originating from 21 different countries.

More inseminations polled bulls
In the first months of 2019, a total of 3.7 percent of the number of Holstein inseminations were performed with polled bulls, according to figures from CRV. The use of polled breeding bulls has been increasing slowly in recent years. In 2013, not even 1 percent of the inseminations were performed with semen from a bull carrying the polled gene. In 2019, the counter so far indicates more than 3.7 percent. This involved in 0.6 percent of the inseminations a homozygous polled bull and in 3.2 percent of the inseminations a heterozygous polled bull.

Predicting moment of insemination and calving with sensors
By combining information from leg and neck sensors and location sensors, the most optimal moment of insemination and calving can be predicted more accurately. With the three sensors the accuracy of the predictions increased considerably. With one sensor, the ideal moment of insemination could be predicted with an accuracy of 58 to 64 percent, when combining three sensors this reliability increased to 72 to 87 percent. For the moment of calving, the same improvement was possible: from 40 to 63 percent accuracy with one sensor to 67 to 79 percent with multiple sensors.
