Electronic Cow-Management: Trust the Data and Breed the Cow as the System Recommends. It Works!

June 2019

As herds get larger and livestock handling systems become more mechanized, time spent on heat detection for each individual cow continues to dwindle. However, next to top nutrition and elite genetics, getting cows to reproduce regularly is the next most important link in the chain of effective farm management. Activity monitoring is becoming increasingly popular as an aid to successful reproduction programs. We sought some practical farm experiences.

Hoof Health: Improvements Possible Via Breeding

June 2019

Problems with hoof health (lameness in cows) is among the biggest irritations of dairy farmers – the costs of lost milk production, additional labour, veterinarian visits, involuntary culling, and lower fertility quickly add up. Via management and nutrition, many hoof issues can be prevented, or at least minimized. But… breeding is also offering more and more possibilities. After Scandinavia and the Netherlands, Canada and Germany also recently introduced official indexes for hoof health.

Extreme Weather is on its Way: Alleviate the Impact of Heat Stress

June 2019

Soon the stifling heat of summer will be with us and that can adversely affect the production levels of high yielding dairy cows. Here we look at some of the management steps you can take to help alleviate the impact and stress to your cows of extreme weather this summer.

Robots and Sire Selection: Breeding “a Robot Cow”

May 2019

Over the forecast period of 2017-2023, the robotic milking market is projected to grow at an annual growth rate of 9.78%. Yes: We can expect a lot more robot dairy farms in the future! From changing the barn to accommodate robots, to learning how to decipher copious amounts of information, changing to an automated milking system brings a whole lot of change. One of these changes is a breeder’s approach to sire selection – here we discuss breeding in the robot world.

LPI and Pro$: The Inner Workings of Canada’s Total Merit Indexes.

May 2019

Canada has two main total merit indexes. The Lifetime Performance Index (LPI) has been the recognized measure of Canadian genetics for decades, while the Pro$ was added as an alternative ranking commencing in August 2015. The Pro$ is targeted to meet the needs of producers who generate essentially all their revenue from milk sales, while the LPI is more suited for those who desire to market genetics, where the conformation and appearance of the animal provide added value.

Beef-on-Dairy: Various Beef Breeds Have Their Own Selection Programs

April 2019

In HI’s February issue (pgs. 10-11) you became acquainted with the phenomenon Beef-on-Dairy: the breeding of dairy cows to beef bulls. As the result of extensive use of sexed semen in many prominent Holstein countries, this is a growing practice. In this article, we will consider a number of breeding programs which have been developed to select the best possible beef bulls to meet this end goal. And you receive an overview of the bulls from various beef breeds that are recommended by AIs for use on dairy cows. Also with Beef-on-Dairy, it is the case: do not use “just any bull”; also here, better bulls clearly lead to better results.

Management: Natural Ways of Disease Prevention

April 2019

Antibiotic resistance and reducing the amount of antibiotics used in livestock production – it’s a topic all livestock producers have heard over and over during the past decade. Of course from a genetic perspective, selection for health traits has arrested the downward trend in health trait performance of the dairy cow and we are now seeing general improvements in disease resistance... but what management options exist as an alternative to antibiotic use?

Mastitis – The New Heavyweight Among Health Traits

March 2019

Theoretically, a breeding value for somatic cell score (SCS), as is routinely calculated in most countries around the world, could continue to serve as a genetic indicator for udder health well into the future. In countries where a breeding value for mastitis is calculated, the correlation between it and SCS can go from 0.6 to 0.9. that is very high. Nonetheless, more and more breeding indexes are directly incorporating breeding values for mastitis. Here we will explain why that is and how mastitis breeding values are obtained.

“Beef on Dairy”: Significant Increase in the Use of Beef Bulls on Dairy Cows

February 2019

In HI, we seldom or never write an article about the beef breeds. Nevertheless, there is a good reason to do that now, because the use of beef bulls on Holstein cows is becoming commonplace. In most Holstein countries, the number of inseminations with so-called “beef on dairy” sires has increased tremendously in recent years, in some cases even to nearly 50%. HI spoke with specialists about the phenomenon “Beef on Dairy”. Which breeds are being used for this? And: what is the emphasis in sire selection?

Wellness Traits: Building a Healthier Herd

February 2019

Use of genomics in official genetic evaluations has transformed the dairy cattle breeding industry over the past decade. Now genomics is being used to offer breeders new options when it comes to selecting healthier animals: the wellness traits.

Preventing Holsteins from Becoming Too Tall

January 2019

The breeding of tall, impressive looking cows has been the goal for many a breeder down through the years. Now, slowly the tide of opinion is changing and many believe the stature of Holsteins is already tall enough. However, the selection for increased stature appears to be built into our breeding systems at various levels. How do we slow the rate of increase in stature of our cows?

TPI and Net Merit: Do You Know Exactly What They Include?

January 2019

With US Holstein genetics playing a major role on the international scene, the TPI is widely recognized and has become a common language understood in many different countries around the world. However, do you know exactly what traits are included in the TPI? Here you can learn in 2 pages about the many valuable traits included!

Lepoint: ‘Genomics Overestimates Popular Families. That Needs to Change.’

December 2018

France has two large breeding companies: Evolution and Gènes Diffusion. At the latter, Frédéric Lepoint has already been employed for 28 years and thus is both a genetic manager and an ambassador. HI spoke with Lepoint about developments at Gènes Diffusion, cooperative efforts and the potential of genomics. Lepoint calls himself “pro-genomics” but places significant conditions on that. Something needs to change, according to this expert.

Cow Comfort: What Are the Main Options for Bedding Material?

December 2018

Improved cow comfort is often listed as a major contributor to increased milk production. Improved barn design, increased air flow and ventilation, better access to the feed bunk, and more spacious stalls all help to make for a more efficient operation. This month we discuss the various choices when it comes to another significant contributor to cow comfort, bedding material.

Bull Fertility - Much Consulted Trait in Sire Selection

November 2018

Timely pregnancy of heifers and cows is critical to the economics of dairy farms. That is the reason why during the past number of years, fertility has received increased attention within breeding programs. It is no longer possible to imagine indexes for daughter fertility being omitted in the sire selection process. But also bull fertility – no matter how small the contribution may be in the total spectrum – is also carefully considered by many farmers. The figure can even be crucial for the career of a bull.

Arnout Dekker about the Positive Effects of OmniGen-AF

October 2018

‘Stress reduces the resistance of cows, causing the likelihood of infections to increase. And the number of stress moments is quite high actually; cows are like people with autism, they do not handle changes well.’ Speaking is Arnout Dekker, a practicing veterinarian with years of experience who now works at Phibro, the supplier of OmniGen, the product that offers proven support to the immune system of, among others, dairy cows, and thus maintains a high resistance level. In turn this results in fewer cases of disease and reduced use of antibiotics.

10 Years of Revolution: Paul VanRaden Looks at the Evolution of Genomics

August 2018

It is now almost 10 years since the arrival of the genomics. In that time it has evolved into the biggest revolution the cattle breeding industry has seen. To look at some of the developments as genomics has been implemented over those 10 years we spoke to Dr Paul VanRaden, a research geneticist with the USDA Agriculture Research Service Animal Genomics and Improvement Laboratory in Maryland.

Growing Demand for AI Equipment

August 2018

A common sight on many farms around the world is the arrivial of the AI technician to breed cows. Now the number of farmers with their own tanks and doing their own inseminations is steadily climbing.

Pieter Karst Bouma: Get the Most from the Cows with a Milking Robot and Extra Information

July 2018

A daily production of 40 kg/cow; Pieter Karst Bouma wants to reach this goal within two years. ‘After raising the roof on the old barn, that is certainly realistic,’ says the farmer from the Dutch province of Friesland. Bouma is in tune with all aspects of his farm and is trying to get the most out of his herd: With the assistance of information from the milking robots and surrounded by the right specialists.

Udder Health: How do you Maintain a Low Somatic Cell Count?

June 2018

Elevated somatic cell counts not only cause production losses, but also increase the likelihood of mastitis, with all the associated problems and costs. To prevent financial damage and animal losses, it is important to decrease, or maintain the somatic cell count on the farm at a low level. Easily said, but what does this look like in practice? Which factors play a big role in this? HI spoke with an independent milking expert and two dairy farmers that have an average somatic cell count of 100,000 or lower.

ProFitPlus in Germany: “The Program for Healthy Cows”

June 2018

“The Program for Healthy Cows”: That is how the ProFitPlus program is described on the websites of the German AIs RinderAllianz (RA) and Rinderzucht Berlin Brandenburg (RBB). For more specific background, experiences and results on this unique project, HI spoke with Jan Körte, Head of Breeding at RA. In his working region, Mecklenburg-Vorpommern, in the far northeastern part of Germany, already since 2005, standardized field data from thousands of cows has been compiled in the areas of mastitis, hoof health and calving, among others. This resulted three years ago in indexes that are much appreciated in the field.

Tremendous Efficiency Potential Possible with Smart Use of Management Support. Top Farms Heading Towards 1 Million Kg Milk per Robot

May 2018

Average daily milk production per robot for all Lely milking robots world-wide reaches 1628 kg, while the top farm is now above 3000 kg! ‘The robots are the same everywhere, the difference lies in management,’ state Lely representatives Frank van der Staak and Rutger van de Streek, who present lots of remarkable data and share engaging stories about the developments of the automatic milking systems, and especially about the growing stream of information from numerous sensors that offer farmers management support. They provide insight about goals, and how to realize those goals with the proper application of modern technology.

Hoof Health: A Trait of Major Economic Importance

May 2018

In August 2011, the Nordic Total Merit (NTM) index – used in Denmark, Sweden and Finland – became the first total index worldwide to include the trait Hoof Health as one its components. ‘Now farmers can see the result for themselves through better longevity and fewer cases of lameness,’ comments Lars Nielsen from Viking Genetics. ‘Hoof health has a correlation of .40 with longevity, while feet & legs have a correlation of just .15/.20 with longevity. Our best bull for Hoof Health reduces the cases of lameness by 50%.’

Dry Cow Management: Crucial Weeks for a Long-lasting Dairy Herd

February 2018

Whether or not to use dry cow treatment, housing in one or two groups, a dry period of six weeks or is eight weeks better? Experts think differently about the ideal dry period. What all experts do agree on, though, is that without a good dry period, milking cows will not get old. HI spoke with Boclair Holsteins in Scotland, the Dijk-de Bruin partnership in the Netherlands and Hendel Farms in the US; three enterprises with high-producing and long-lasting herds that have proven to have good dry cow management.

Barn Equipment To Boost Milk Production

December 2017

Whether you are thinking about enhancing your existing barn or building a new one –integrating milk-boosting tools will most likely be an advantageous goal. Here we investigate some possibilities.

Key Management Factors at Pine Tree Dairy

September 2017

The name Pine-Tree is synonymous with the Rudolph Missy family. Bulls such as Supersire, Mogul, Balisto – the most dominant bulls of the genomic era – all stem from the Missy family that was developed at Pine-Tree. However, this month we are not focusing on the Rudy Missy family but instead on the management practices of this world-renowned Ohio dairy operation.

Calf Raising: Focus on Colostrum Management gives Calves a Good Start

August 2017

One of these busy mornings when you are lamenting the fact that you have so many calves to feed, spare a thought for Ty Fullmer and his team at Fullmer Cattle Company in Kansas – they raise 35,000 calves per year! We talked with Ty to discover what it takes to have success in calf raising.

TransitionRight: Breeding Healthier Cows

August 2017

Selection emphasis on fitness traits over the last 15 years has arrested the declining genetic merit for health in the dairy cow that had developed as an unwanted side-effect of many years of intensive selection for production. While progress in breeding a healthier cow has been slow, we now have some proprietary indexes to help select for improved health. Here we highlight the TransitionRight program from ABS.
