ADSA® Develops the Next
Generation of Leaders
Developing the next generation of leaders for the dairy industry is an important objective for the American Dairy Science Association® (ADSA). ADSA sponsors programs for challenging and developing youth for leadership responsibilities. To accomplish this objective, ADSA leans on its student divisions including the
Graduate Student Division (GSD)
and
Student Affiliate Division (SAD).
Both focus on career development, professional growth and leadership development for their members.
In addition to organizational meetings and research presentations, several student activities were included in the recent ADSA Virtual Annual Meeting that encouraged networking and professional development for students.
Bethany Dado-Senn, 2019-2020 President of the GSD, and Jack Myers, 2019-2020 President of the SAD, provided some thoughts on these leadership development activities and networking opportunities that were available through ADSA.
Bethany Dado-Senn shared:
“The Graduate Student Division advisory council was very pleased with student participation in all aspects of the meeting, particularly in research dissemination through virtual abstracts as well as engagement in our career development opportunities. Over 140 students interacted with professional members through two Mix and Mingle sessions and a Career Insights Panel, where we gained valuable insights on areas such as career preparedness, professional and personal commitments, time and team management, and job seeking during a pandemic. Our attendees enjoyed interacting and learning from these professional members, while student-to-student conversations were also facilitated via the chat feature.
The GSD would like to acknowledge the continuous support of ADSA professional members in graduate student endeavors. It was apparent in both the planning and execution of this virtual meeting that student research and professional development were key priorities for ADSA leadership. We also thank professional members who contributed to our GSD events for their time and advice. We hope we can continue to foster these virtual relationships and eventually continue our in-person networking when possible.”
Jack Myers shared:
“SAD Mentoring Sessions: The move to virtual for the SAD mentoring sessions, still provided the same experience and networking opportunities as if we were on site. Professional ADSA members were still able to meet with SAD members and provide valuable advice ranging from graduate school, analyzing posters, and providing specific science based knowledge.
SAD Career Roundtable: While taking a different form this year, the SAD career roundtable featured four panelists consisting of a nutritionist, dairy consultant, extension agent, and a graduate student. Members were able to ask questions in the zoom chat feature and discussion was moderated by SAD officers. SAD members were provided with valuable advice regarding careers in the dairy industry and how the dairy industry is coping with the covid pandemic.
SAD members were also able to enjoy a social night where three small groups of students interacted with virtual game hosts to play a wide variety of games, all while networking with other students.
Overall, SAD members were still able to enjoy nearly all of their typical programming, with only a few minor virtual hiccups. ADSA was yet again able to provide key programming for SAD members, giving them opportunities to network with fellow members and the science presented at the annual meeting. All aiding SAD members as they pursue graduate school or careers in the industry.”
ADSA looks forward to the next generation of scientists and industry leaders present in the GSD and SAD membership and to supporting students in their careers as Professional Members of ADSA in the future.

Heat stress in gestating dairy cows impairs performance of future generations
Research in the
Journal of Dairy Science
®
studies lasting effects of heat stress on dairy cows
It is estimated that in the United States, environmental heat stress in cows costs the dairy industry more than $1.5 billion annually due to decreased milk production, impaired reproductive performance, increased rates of illness, and shortened lifespans. But what effects do heat stress in pregnant cows have on the productivity and health of their female offspring in the future, and how much might this affect dairy producers’ costs? In a recent
article
appearing in the
Journal of Dairy Science
, scientists from the University of Florida and the University of California, Davis investigated the performance and profitability of two future generations of cows born to mothers exposed to heat stress during pregnancy.
According to senior author Jimena Laporta, PhD, of the Department of Animal Sciences at the University of Florida, Gainesville, FL, USA, previous research has found that heifers born to cows that are heat-stressed during late gestation grow to be smaller and produce on average five kilograms per day less milk in their first lactation, compared with heifers born to dams that were cooled during the hottest days of the year.
“This suggests a permanent effect of fetal environment on genetic expression in adulthood,” said Laporta. “We hypothesized that exposure of pregnant cows to heat stress during late gestation will impair daughters’ and granddaughters’ lifetime performances.”
The authors’ first objective was to measure the carryover effects of maternal exposure to heat stress during late gestation on milk yield, reproductive performance, and survival rates of daughters and granddaughters. Their second was to estimate the economic losses related to those outcomes across the United States. Laporta and colleagues pooled and analyzed data collected over a 10-year period on performance of Holstein cows in Florida, the state with the greatest number of heat stress days per year. This gave them information on the lifespans, productivity, and reproductive performance of two successive generations of cows born to dams exposed to heat stress during pregnancy and those born to dams that were provided active cooling during heat stress periods.
The authors found that, as expected, daughters and granddaughters of heat-stressed cows showed negative effects in rates of survival from birth to first calving, length of productive lifespan, and milk performance, including milk yields and nutrient contents through the first three lactations. The team calculated that these impairments translate to considerable annual costs to dairy producers in the United States, with nationwide losses, based on the US average milk price from 2010 to 2015, of up to $595 million annually.
Laporta notes that lactating cows tend to be the focus of heat reduction strategies, possibly because the effects of overheating are more immediately evident among them than among nonlactating pregnant cows, for which the damage may become apparent only later, when they resume milking. But considering the hidden costs that carry over to future generations of cows and the likelihood of increased heat stress due to ongoing climate change, Laporta and colleagues consider cooling techniques for dry cows—such as the use of fans and sprinkler systems—crucial to the continued success of the US dairy industry.

Cheese making relies on milk
proteins to form structure
Protein composition of milk affects coagulation and consequently cheese yield according to a study in the
Journal of Dairy Science
®
Cheese production relies on coagulation of milk proteins into a gel matrix after addition of rennet. Milk that does not coagulate (NC) under optimal conditions affects the manufacturing process, requiring a longer processing time and lowering the cheese yield, which, in turn, has economic impact. In an
article
appearing in the
Journal of Dairy Science
, scientists from Lund University studied the protein composition of milk samples with different coagulation properties to learn more about why only some milk coagulates with rennet.
The authors of this study analyzed protein composition in NC and coagulating milk samples from 616 Swedish Red cows. They reported that the relative concentrations, genetic variants, and posttranslational modifications of the proteins all contribute to whether rennet could induce coagulation in each sample. The NC milk had higher relative concentrations of α-lactalbumin and ß-casein and lower relative concentrations of ß-lactoglobulin and κ-casein when compared with coagulating milk.
“The non-coagulating characteristics of milk relate to protein composition and genetic variants of the milk proteins,” said first author Kajsa Nilsson, PhD, Lund University, Lund, Sweden. “Roughly 18 percent of Swedish Red cows produce noncoagulating milk, which is a high prevalence. Cheese-producing dairies would benefit from eliminating the NC milk from their processes, and breeding could reduce or remove this milk trait,” said Nilsson.
These results can be used to further understand the mechanisms behind NC milk, develop breeding strategies to reduce this milk trait, and limit use of NC milk for cheese processing.
