  • Creating an experience that makes the interaction between technology and farmers as intuitive as possible.


Putting Value on Purity and Conception
Kevin Ziemba, STgenetics
Sponsored by STgenetics

As dairies emphasize where their heifer calves come from, the purity and conception of the sexed semen they use has a greater economic value. Unwanted heifers from bottom cows are not necessary for a dairy, but likewise incrementally minimizing bull calves from top-end cows can add huge value to herds that want only replacement heifers and beef calves born on the farm. If we can improve the percent of heifer calves through purity and maximize conception rates through semen quality, dairies can manage with precision and efficiency.


Can Intranasal Vaccines Impact Health and Performance of Immune Challenged Calves and Dairy Cows?
Victor Cortese, Zoetis
Sponsored by Zoetis

Stress and challenged cattle can suffer from immune suppression, leading to increased disease risk, performance and production losses, failure to respond to vaccinations and even culling and death. This happens in calves, as well, as even the stress calving places on adult dairy cows. Research into how intranasal vaccines can provide a different pathway to get immune responses that improve health and performance has only recently emerged. Some of the latest research into this area will be presented.


New Technologies, Data-driven Decision Making and How to Make Sense of it All
Michel Baldin, milc group
Sponsored by milc group

While sometimes it’s okay to follow your instincts, the vast majority of your business-based decisions should be backed by metrics, facts or figures related to your aims, goals or initiatives that can ensure a stable backbone to your dairy operations. In this session, we will discuss scenarios where we can implement successful data-driven decision-making strategies to help your dairy become more profitable and sustainable. We will talk about selecting the appropriate new technology to measure variables of interest and what to do after data have been collected. Tips will be provided to help attendees implement data-driven decision-making strategies to enhance cow nutrition, reproduction, health, team management and increased overall bottom line. Remember, if you can’t measure it, you can’t improve it (Peter Drucker).


Supporting Normal with Effective Probiotics
Steve Lerner, Chr. Hansen
Sponsored by Chr. Hansen

There is a large and continuously growing body of evidence that effective probiotics support all of the normal functions of the gastrointestinal tract, including, digestive, absorptive, barrier and immune functions. All humans, from premature infants in neonatal intensive care units to the elderly, benefit from daily ingestion of effective probiotics. All production animals, from birth to departure, benefit from daily ingestion of effective probiotics. Effective probiotics increase the likelihood of us and the animals in our care being normal. As a producer or supporting nutritionist or veterinarian, what would feel better than having every animal in your herd, lot, flow or flock be normal?

How the Immune System Affects Transition Cow Performance
Lance Baumgard, Iowa State University
Sponsored by TechMix, Inc

Transition dairy cow immune activation is caused by metritis, mastitis, leaky gut and lung infections. Even in seemingly healthy cows, there is subacute inflammation. The engaged immune system takes priority over milk synthesis and nutrients (glucose, calcium, amino acids), which would have otherwise been used by the mammary gland to make milk, used by the immune system. Thus, the severity of immune stimulation has a large influence on immediate and long-term cow profitability. Minimizing immune activation and nutritional strategies aimed at mitigating transition cow illness will be reviewed.

R.E.S.E.T-ing the Dairy Industry to Attract and Retain Employees
Jorge Delgado, Alltech
Sponsored by Alltech

For all producers, one of the most important resources is farm labor. While it may not be easy to find people willing to work long hours – especially long hours of performing the physically demanding task of milking cows – we should make every effort to attract and retain people to work on our dairies. Although this is not an easy task, with the right conditions and the right tools, employees will see the dairy industry as a unique place that supports and cares about them.

Dairy producers and industry supporters must change their mindset about human resources and start dedicating time and effort to this area, regardless of the size of their dairies. This does not require a big investment, but it does require time and securing the right information about how to reduce the challenges around labor and the workforce. Attracting and retaining employees is not a new problem, but the current circumstances are different than before, mainly driven by immigration challenges and competition for labor with other industries.

To create a positive culture on a dairy, the organizational basics must be in place and there should also be a reset in the way employees are managed. R.E.S.E.T the business to create the right organizational structure for reducing turnover and minimizing employee management frustrations.

Dry Cow Therapy: Aim, Applicability and Advice (Presented in Spanish)
Maristela Rovai, South Dakota State University assistant professor and extension dairy specialist
Raul Mendoza, South Dakota commercial dairy farm herdsman

Dry therapy is a common practice among dairy cattle farms and its proper management plays a key role in the following lactation. Drying off involves interrupting lactation for generally 45 to 60 before calving. In this period, in addition to the demanding final phase of fetus development, there are structural changes in the mammary gland secretory tissue that influence both colostrum and milk production in the subsequent lactation.

One of the most important concerns during the dry period is the high gland susceptibility to intramammary infections. To ensure a cow’s comfort and udder health during this period, several dry-off protocols are available that may include prophylactic antimicrobials and teat sealants. Dry cow therapy may seem simple, but it requires care, consistency and responsibility.

In this session, participants will receive an update on the recommendations and precautions to be considered during drying-off treatment. In addition, attendees will have a real udder, hands-on experience to apply the knowledge acquired in this talk.

This workshop will be offered in Spanish.

Terapia de Secado: Objetivo, Aplicabilidad y Recomendaciones
Maristela Rovai, South Dakota State University assistant professor and extension dairy specialist
Raul Mendoza, South Dakota commercial dairy farm herdsman

La terapia de secado es una práctica común entre las explotaciones de vacuno lechero, y el buen manejo de la misma juega un papel clave en la siguiente lactancia. El secado implica interrumpir la lactación por generalmente 45-60 días antes del parto. En este periodo, además del desarrollo final del feto que exige más energía por parte de la vaca, hay cambios estructurales del tejido secretor de la ubre que influyen tanto en la producción del calostro como en la producción de leche en la siguiente lactación.

Una de las preocupaciones más importantes durante este periodo de descanso o “renovación” de la glándula es la susceptibilidad a las infecciones intramamarias. Para asegurar la salud de la ubre durante este periodo, se disponen de varios protocolos de secado que pueden incluir antimicrobianos de uso profiláctico y sellador de pezones. La terapia de secado puede parecer sencilla, pero exige cuidado, consistencia y responsabilidad.

En esta charla, los participantes recibirán una actualización sobre las recomendaciones y cuidados necesarios al momento de secar las vacas antes del parto. Además, se llevará a cabo una disección de ubre para aplicar los conocimientos adquiridos en la charla. El taller será ofrecido en español.


R.E.S.E.T. eando la industria lechera para atraer y retener empleados
Jorge Delgado, Alltech
Patrocinado por Alltech

Para todos los productores, uno de los recursos más importantes es la mano de obra agrícola. Si bien puede que no sea fácil encontrar personas dispuestas a trabajar largas horas, especialmente largas horas de realizar una tarea físicamente exigente como la de ordeñar vacas, debemos hacer todo lo posible para atraer y retener a la gente para trabajar en nuestras lecherías. Aunque esta no es una tarea fácil, con las condiciones y las herramientas adecuadas, los empleados verán a la industria lechera como un lugar único que los apoya y se preocupa por ellos.

Los productores de leche y los que apoyan la industria deben cambiar su mentalidad sobre los recursos humanos y comenzar a dedicar tiempo y esfuerzo a esta área, independientemente del tamaño de sus lecherías. Esto no requiere una gran inversión, pero sí requiere tiempo y asegurar la información correcta sobre cómo reducir los desafíos en torno a la mano de obra y la fuerza laboral. Atraer y retener empleados no es un problema nuevo, pero las circunstancias actuales son diferentes a las anteriores, impulsadas principalmente por los desafíos de inmigración y la competencia por el trabajo con otras industrias.

Para crear una cultura positiva en una lechería, los conceptos básicos de la organización deben estar en su lugar y también debe haber un restablecimiento en la forma en que se manejan a los empleados. Hay que R.E.S.E.Tear el negocio para crear la estructura organizativa adecuada para reducir la rotación de empleados y minimizar las frustraciones del manejo de empleados.

Prácticas de manejo alimentario para mejorar la rentabilidad de la explotación y la salud de las vacas
Fernando Diaz

El coste de alimentación continúa siendo el mayor coste individual en los sistemas intensivos de producción lechera. Según el Servicio de Investigación Económica del Departamento de Agricultura de los EEUU (USDA), durante la última década el coste de alimentación representó entre el 42 y el 56% del coste total de producción de leche. Con el coste de los alimentos constituyendo el mayor coste operativo, la nutrición y las prácticas de manejo alimentario son los principales factores que afectan a la rentabilidad de las lecherías. Este seminario, dirigido a Encargados y Técnicos de Alimentación, explicará la fisiología y comportamiento

Alimentario de las vacas lecheras, prácticas de manejo enfocadas en el suministro de una dieta consistente a lo largo de un periodo de 24 horas para prevenir la selección de alimentos y maximizar la producción de componentes lácteos y, con ello, la rentabilidad del negocio.
